Our sales team needs custom reports that aren't available out-of-the-box. How do I hire a good CRM developer?

If your sales team needs custom CRM reports that the platform can't provide natively, I’d hire for a CRM developer/solutions engineer, not simply a generic software developer or CRM administrator.

The key is to first determine whether the problem actually requires code. A strong CRM developer should be able to tell you when a native report, data model change, workflow, or configuration is sufficient—and when custom development is justified. Salesforce, for example, explicitly distinguishes declarative customization from programmatic development.

What to look for

• Deep experience with your exact CRM: Salesforce, HubSpot, Dynamics 365, etc. Platform-specific experience matters much more than a generic "CRM developer" title.
• Reporting and data-model expertise: They should understand objects/tables, relationships, calculated fields, aggregations, permissions, and data quality—not just how to make pretty dashboards.
• API/integration experience: Particularly important if your reports need data from ERP, billing, marketing, or other systems. HubSpot recommends REST API, backend development, version control, and integration experience for CRM developers.
• Automation skills: A good candidate should know when to use native automation versus custom code.
• Security and permissions: Make sure they understand record-level access, sensitive fields, authentication, and least-privilege access.
• Testing and deployment: Look for Git/version control, development/test environments, automated testing where appropriate, and documented deployments.
• Business understanding: They should be able to translate "the VP wants a pipeline report" into precise definitions of pipeline stages, attribution, dates, ownership, exclusions, and calculations.

If you're on Salesforce, a Salesforce Platform Developer certification is useful evidence, although I wouldn't make certification a substitute for production experience. Salesforce describes that certification as covering custom business logic, interfaces, data modeling, and the distinction between declarative and programmatic solutions.

How I'd interview them

Give candidates a real but sanitized version of one report your team needs.

For example:

"Sales wants a report showing each rep's qualified pipeline created this quarter, the amount that ultimately closed, average days to close, and conversion rate. It needs to exclude renewals and split results by lead source." Then ask them to:

1. Explain what information they'd need before building it.
2. Identify whether the CRM can do it natively.
3. Sketch the data model/query/report architecture.
4. Explain what they'd do if one required metric isn't available in the CRM.
5. Describe how they'd test the numbers against existing sales data.
6. Explain how they'd deploy the change without disrupting production.
7. Estimate the work and identify risks.

Pay particular attention to their questions. A mediocre developer immediately starts talking about code. A good CRM developer first asks what "qualified," "created," "closed," "conversion," and "renewal" actually mean.

HubSpot's own developer-hiring guidance similarly recommends practical technical assessments, behavioral questions, and having another developer review the assessment rather than relying solely on résumé claims.

Where to hire

I'd consider three options:

• Freelancer/contractor: Best if you have a defined set of reports and integrations. Start with a paid pilot before committing to a long engagement.
• Specialist CRM consultancy: Better if the project involves messy data, multiple integrations, or architecture decisions.
• Full-time hire: Makes sense if your sales organization will continually need CRM customization, integrations, automation, and reporting.

For a relatively contained reporting problem, I'd start with a specialist contractor on a small paid discovery project, rather than immediately making a full-time hire.

One important hiring trap

Don't advertise simply for a "CRM developer." That can attract people who mean very different things by the term: someone configuring Salesforce/HubSpot, an API/integration engineer, or a general full-stack developer building a CRM product.

Instead, specify:

CRM platform + reporting problem + integrations + expected deliverables + required technical skills.

For example: "Salesforce developer needed to design custom sales reporting, extend Salesforce data model where necessary, build Apex/LWC only where native reporting cannot meet requirements, and integrate external revenue data via REST APIs."

If you tell me which CRM you use (Salesforce, HubSpot, Dynamics, etc.) and roughly what the custom reports need to show, I can also give you a specific job description, candidate scorecard, and 30-minute interview test tailored to it.

To hire a good CRM developer for custom sales reports, you must first define your specific CRM platform (such as Salesforce, HubSpot, or Microsoft Dynamics) and outline your exact data requirements.

Steps to Hire a CRM Developer

Key Skills to Look For

To help narrow this down, could you tell me:

• Which CRM platform are you currently using?
• Are you looking for a freelancer for a quick project or a full-time hire?

Yes. The key is to hire for CRM problem-solving, not just generic programming ability. A good CRM developer should understand your sales process, data model, reporting needs, and the CRM platform itself.

1. Define the work before hiring

Write down 3–5 concrete examples of what you need, such as:

• “Create a pipeline report that combines opportunities, activities, rep performance, and forecast data.”
• “Build a dashboard showing conversion rates by source, territory, and sales stage.”
• “Automate a weekly executive report.”
• “Integrate CRM data with our data warehouse.”
• “Create custom objects/fields and reporting logic that standard CRM reports can't handle.”

This matters because sometimes the right hire is a CRM administrator/consultant, not a developer. For Salesforce, for example, many customizations don't require code; Salesforce recommends using a developer when requirements go beyond configuration or involve custom code, complex integrations, or data migration.

2. Look for these skills

The exact stack depends on your CRM, but prioritize:

• Deep experience with your CRM — Salesforce, HubSpot, Dynamics, etc.
• Data modeling — understands objects/tables, relationships, calculated fields, and reporting data.
• APIs and integrations — especially if reports need data from other systems.
• Automation/workflows — can determine whether something should be solved with native automation or custom code.
• Reporting/analytics — understands how the underlying data affects report accuracy.
• Security and permissions — particularly important when sales reps and managers should see different data.
• Testing and deployment — you don't want someone making ad-hoc production changes.
• Business analysis and communication — arguably as important as coding. Salesforce itself lists understanding business requirements and choosing the appropriate low-code/code solution among core developer skills.

For example, Salesforce developers commonly work with Apex, JavaScript/Lightning Web Components, SOQL, APIs, data modeling, testing, and DevOps.

3. Give candidates a realistic test

Don't give them a generic coding puzzle.

Instead, give them a sanitized version of one of your actual reporting problems:

“Sales leadership wants to see pipeline by rep, stage, source, and quarter. They also want conversion rate from opportunity creation to closed-won. The standard report currently produces incorrect conversion rates because opportunities can move backward between stages. How would you design this?” Ask the candidate to explain:

1. What data they need.
2. What questions they'd ask the sales team.
3. Whether native CRM reporting is sufficient.
4. What they'd customize if it isn't.
5. How they'd validate the numbers.
6. How they'd deploy and maintain it.

A strong candidate will probably spend more time clarifying the business requirement than immediately proposing code.

4. Check their portfolio differently

Don't just ask, “Have you built Salesforce reports?”

Ask:

• “Show me a CRM customization you've personally built.”
• “What was the business problem?”
• “What did the native CRM functionality fail to do?”
• “What did you build instead?”
• “How much of it was configuration versus code?”
• “How did you test it?”
• “What broke after launch?”
• “Who maintains it now?”

For HubSpot specifically, its own developer guidance emphasizes full-stack/backend development, REST APIs, Git/version control, JavaScript, and CRM-specific customization experience.

5. Use a short paid project before a big commitment

If you're hiring a contractor or freelancer, I'd strongly consider:

Phase 1: paid discovery (5–15 hours) Phase 2: one representative report/customization Phase 3: broader engagement if they're good

This lets you evaluate whether they can actually work with your CRM rather than relying on certifications and interviews.

6. Ask these interview questions

A few particularly revealing ones:

• “Tell me about a CRM project where you initially chose the wrong technical approach. What happened?”
• “When would you not write custom code?”
• “How do you make sure a sales dashboard's numbers are actually trustworthy?”
• “How do you handle changing requirements from sales leadership?”
• “How would you prevent a custom report from becoming unusably slow as our data grows?”
• “How do you document customizations so another developer can take over?”
• “What would you want access to before you gave us an estimate?”
• “If the CRM can't produce the report we want, how would you decide between extending the CRM and moving the analytics to a warehouse/BI tool?”

That last question is especially important. You don't want someone who solves every reporting problem by stuffing more customization into the CRM.

7. Where I'd look

For a platform-specific developer, start with the platform's own ecosystem/community and specialized recruiting channels rather than a generic “software developer” search. Salesforce, for example, maintains a developer community and certification/training ecosystem.

When searching, use terms like:

• Salesforce Developer / Salesforce Technical Consultant
• HubSpot CRM Developer
• CRM Solutions Architect
• CRM/RevOps Developer
• Salesforce Analytics/CRM Analytics Developer
• CRM Integration Developer

If your primary need is custom sales reporting, I'd lean toward someone with CRM + RevOps/data/analytics experience, rather than a pure application developer.

One important hiring distinction

If you tell me which CRM you're using (Salesforce, HubSpot, Microsoft Dynamics, Zoho, etc.), roughly how many salespeople you have, and what your custom reports need to show, I can give you a much more specific hiring profile—including the right job title, must-have skills, interview exercise, and where I'd recruit them.

Hiring a great CRM developer to build custom reporting loops starts with defining your ecosystem. Since your main bottleneck is reporting, you need someone who understands not just the code, but data architecture and sales workflows.

A step-by-step roadmap will help you source, vet, and land the right person.

1. Pinpoint Your Ecosystem and Scope

• Identify your platform: A Salesforce developer (Apex, SOQL) has a very different skillset than a Microsoft Dynamics 365 developer (C#, Power BI, FetchXML) or a HubSpot/Zoho developer.
• Define the reporting requirement: Write down what "custom report" means for your sales team. Is it pulling data across multiple custom objects, real-time revenue forecasting, or external database integration?
• Determine the engagement type: Decide if this is a one-off project (freelance/agency via platforms like Toptal ) or a permanent/long-term addition (sourced via LinkedIn).

2. What to Look For (The Checklist)

• Platform Certifications: Look for official credentials (e.g., Salesforce Platform Developer I/II or Microsoft Dynamics 365 Certified Developer) to prove baseline competency.
• Data Modeling & SQL Skills: Custom reporting requires deep database savvy. They must know how to write efficient queries that won't lag or hit platform governor limits when your sales data scales.
• Business Acumen: A great CRM developer doesn’t just take orders; they talk to your sales managers, understand why a metric matters, and design data structures that map to your actual pipeline stages.

3. Sourcing Channels

• Vetted Networks: For contract or fractional work, curated networks like Toptal or specialized boutique agencies save you from filtering through hundreds of unqualified resumes.
• Professional and Peer Networks: LinkedIn is ideal for full-time hires. Search for developers who specialize explicitly in your CRM's reporting and analytics extensions.
• Community Forums: Look at active contributors on Salesforce Stack Exchange or GitHub communities tied to your specific CRM.

4. Key Screening & Interview Questions

• "Can you describe a time you had to build a complex custom report or dashboard that the native CRM couldn't handle? What was your data architecture approach?"
• "How do you optimize queries to avoid performance degradation or platform limits as data grows?"
• The Practical Test: Give them a anonymized, scaled-down version of your reporting challenge. A paid 2-to-4-hour mini-project or a live technical walkthrough reveals how they structure logic and handle messy data.

To help you narrow this down, could you tell me:

• Which CRM platform are you currently using?
• Are you looking for a full-time hire or a freelancer/agency for a specific project?

Hiring a great CRM developer requires looking past generic coding skills and testing for specific platform architecture, data modeling, and business logic experience.

Here is a structured roadmap to find, vet, and hire the right person for your team:

1. Define Your Technical & Business Scope

Before writing a job description, pinpoint what "custom reports" actually means for your tech stack.

• Platform specification: Identify your exact CRM (e.g., Salesforce, HubSpot, Microsoft Dynamics, Zoho). A Salesforce Apex/LWC developer is entirely different from a HubSpot custom-coded card developer.
• Data complexity: Determine if the reports require simple SQL/SOQL queries, multi-object joins, or external data warehousing connections (like Snowflake or BigQuery).
• Integrations: Clarify if data needs to be pulled from ERPs, marketing automation, or billing tools before hitting the report layer.

2. Write a Targeted Job Description

A great CRM developer wants to solve architectural challenges, not just take ticket orders.

• Responsibilities: Focus on data modeling, optimizing query performance, building custom reporting dashboards, and maintaining API data integrity.
• Requirements: Explicitly list the required native languages (e.g., C#, Python, Apex, JavaScript) and platform-specific certifications (e.g., Salesforce Platform Developer I/II).
• Red Flag Avoidance: State clearly whether you need an administrator who can configure reports or a true developer who can write custom backend/frontend extensions.

3. Source Candidates Where They Hang Out

• Niche Communities: Look on platforms like Upwork or Toptal for vetted, freelance CRM specialists if this is a project-based need.
• Professional Networks: Search LinkedIn using specific certification keywords rather than generic titles.
• Developer Forums: Check community boards like the Salesforce Trailblazer Community or GitHub contributors for specific CRM repositories.

4. Vet for Real-World Competence

During interviews, skip generic coding puzzles and test practical CRM scenarios.

• Architecture Question: Ask how they would handle a custom report that requires aggregating data across 500,000+ records without hitting platform governor limits or crashing performance.
• Data Governance: Ask how they handle PII (Personally Identifiable Information) and role-based data security within custom report types.
• Portfolio Review: Ask them to walk through a past custom reporting or data visualization project they built from scratch, explaining the trade-offs they made.

If you'd like to narrow this down, let me know:

• Which CRM platform are you using?
• Is this a full-time hire or a contract project?
• Are the custom reports meant to live inside the CRM or in an external BI tool (like Tableau or PowerBI)?

Yes. The key is to hire for CRM-specific problem solving, not just “someone who knows the CRM.” For custom sales reporting, I’d structure the search like this:

1. Define the work before you hire

Write down 3–5 concrete examples of what the sales team needs, such as:

• “Show pipeline by rep, territory, product, and expected close month.”
• “Combine CRM opportunities with billing data.”
• “Create a report that calculates conversion rates across custom stages.”
• “Give executives a dashboard while restricting reps to their own accounts.”
• “Automate a weekly report that currently requires spreadsheet work.”

Also specify your CRM: Salesforce, HubSpot, Dynamics, etc. The technical skill set differs substantially.

2. Look for these skills

A strong candidate should be able to:

• Understand your CRM's data model, relationships, custom objects/fields, and reporting limitations.
• Determine whether a requirement can be solved with native configuration before writing custom code.
• Work with APIs and integrations if the required data lives outside the CRM. Salesforce, for example, emphasizes API integration, testing in staging, and carefully scoped permissions.
• Build maintainable queries/reporting logic rather than hard-coding one-off numbers.
• Understand permissions and data security—particularly important when sales reps should see different records.
• Communicate with nontechnical sales/operations people and translate “I want this dashboard” into an actual technical specification.

For Salesforce specifically, useful experience includes Apex, SOQL, Lightning Web Components, APIs, testing, version control and deployment. www.salesforce.com For HubSpot, REST APIs, CRM objects/associations, authorization and custom extensions are particularly relevant.

3. Don't make certifications the deciding factor

A certification is a useful signal, but I'd rank demonstrated CRM work higher.

Ask candidates:

“Tell me about the most complicated custom report or CRM data problem you've solved. What did the business want, what couldn't the native CRM do, and what did you build?”

A good candidate should be able to explain the business problem → data model → solution → tradeoffs → testing → deployment clearly.

4. Give finalists a small practical exercise

This is probably your best screening mechanism.

Give them a fictional scenario like:

“We have Opportunities, Accounts, Sales Reps and Products. Management wants pipeline coverage by territory and month, win rate by rep, and average sales cycle. Some revenue data is in an external billing system. Reps must only see their own opportunities.”

Ask them to spend 60–90 minutes explaining how they'd implement it.

Evaluate:

5. Hire someone who can say “no”

This is surprisingly important.

A mediocre CRM developer hears:

“Can you build this custom dashboard?”

and immediately starts coding.

A strong one says:

“Before we build that, let's determine why the existing report can't produce it. We might be able to fix the underlying data model or use a native reporting feature.”

That prevents you from accumulating expensive customizations that become difficult to maintain.

6. Where I'd look

For a full-time employee, search for titles like:

• CRM Developer
• Salesforce Developer
• HubSpot Developer
• CRM Engineer
• Sales Systems Engineer
• Revenue Operations Engineer

For a contractor, look for someone who has several relevant CRM implementations you can independently verify. Ask for references specifically from the people who used the CRM—not just the project manager.

7. Make the contract protect you

For a contractor, require:

• Work in your CRM environment/accounts.
• Code and configuration belong to your company.
• Version-controlled source where applicable.
• Documentation of custom reports, scripts, integrations and data models.
• Testing/staging before production.
• No shared credentials.
• Least-privilege access.
• A defined handoff period.

This matters because CRM development often involves customer data and powerful API credentials; official CRM guidance recommends restricting permissions and securely managing authentication tokens.

My biggest recommendation: before posting the job, give me which CRM you're using (Salesforce, HubSpot, Dynamics, etc.), roughly how many sales reps you have, and 2–3 examples of the custom reports you need. I can then give you a precise candidate profile, interview questions, and a practical skills test tailored to your setup.

Yes. The key is to hire for CRM architecture + business requirements + integration skills, not simply someone who knows how to build reports.

1. Define the actual problem first

Before interviewing anyone, write down 3–5 examples of the reports your sales team wants but can't currently produce:

• What question should each report answer?
• Which CRM objects/data are involved?
• Where does the data currently live?
• Who needs the report and how often?
• Does it need to update automatically?
• Does the requirement involve data from other systems?

This helps distinguish a straightforward CRM configuration job from a genuine development/integration project.

2. Look for these skills

A strong CRM developer should be able to:

• Translate sales requirements into a data model
• Understand custom objects/fields and relationships
• Build automation and custom reporting
• Work with APIs and integrations
• Write and test code where the CRM's native tools aren't enough
• Diagnose data-quality problems
• Explain technical tradeoffs to nontechnical salespeople
• Document what they build so you're not dependent on one person

For example, Salesforce's own developer guidance emphasizes data modeling, APIs/integration, testing, automation, and the ability to understand business requirements—not just programming.

3. Hire someone with experience in your CRM

Don't hire a generic "CRM developer" if you already know the platform.

Salesforce: Look for experience with Apex, SOQL, Lightning Web Components, APIs, data modeling, reports/dashboards, and deployment/version-control practices. trailhead.salesforce.comwww.salesforce.com You can also find certified consulting partners through Salesforce's current Partner Finder.

HubSpot: Look for CRM development, APIs, integrations, databases/data structures, and ideally experience with custom integrations. HubSpot's Solutions Directory lets you filter partners by service, industry, credentials, and reviews; it specifically lists CRM implementation and custom-integration expertise.

4. Give candidates a small practical test

This is probably the best screening method.

Give them a sanitized version of one difficult report request and ask:

"Our VP of Sales wants a report showing pipeline created by salesperson, segmented by lead source, with conversion rates and average days from opportunity creation to close. Some of the required data comes from another system. How would you approach this?"

Don't require them to build the whole thing. Ask them to spend 30–60 minutes explaining:

1. What data they'd need
2. What they'd configure natively
3. What they'd custom-develop
4. What questions they'd ask the sales team
5. How they'd validate the numbers
6. How they'd make the solution maintainable

A good developer will probably ask questions before proposing a solution.

5. Ask for evidence, not just certifications

Certifications are useful, but ask candidates to show—without exposing confidential client information—two or three comparable projects.

Ask:

• What was the customer's problem?
• What did you personally build?
• What couldn't the CRM do natively?
• Did you integrate another system?
• How did you handle bad/inconsistent data?
• How did you test it?
• What happened when requirements changed?

For HubSpot specifically, its accreditation program distinguishes more rigorous partner accreditation from ordinary certifications and looks for demonstrated expertise and practical experience.

6. Decide whether you need a freelancer, employee, or consulting firm

Freelancer: Best for a defined project with limited ongoing maintenance.

Full-time developer: Makes sense if your CRM is becoming a core business system and you'll have a continuing stream of custom work.

Specialized CRM consultancy: Often best if the problem involves architecture, integrations, data migration, automation, and reporting across multiple systems. You're buying a team rather than depending on one developer.

For your situation, I'd probably start with a specialist for a short discovery/architecture engagement, rather than immediately hiring a permanent developer. Have them inventory the reporting gaps, data sources, and technical constraints, then use that work to determine whether you need ongoing development.

Red flags 🚩

Be cautious if someone:

• Immediately proposes custom code without understanding the business requirement
• Can't explain the CRM's native capabilities
• Has lots of certifications but no comparable project examples
• Doesn't talk about testing or data quality
• Wants to build everything directly in production
• Can't explain their work to a salesperson
• Doesn't document their solution
• Says "yes" to every request without discussing tradeoffs

The single best interview question:
"Show me a CRM project where the obvious solution wasn't the right solution. What did you recommend instead, and why?"

That tends to reveal whether you're talking to someone who can engineer a CRM solution versus someone who simply knows how to configure screens and reports.

Hiring a good CRM developer for custom reporting requires targeting specific technical skills, platform experience, and data visualization capabilities.

Follow this structured approach to find and vet the right talent:

1. Define Your Technical Requirements

Before writing a job description, pinpoint what your custom reports actually entail.

• Platform Experience: Identify your exact CRM (e.g., Salesforce, HubSpot, Microsoft Dynamics, Zoho). Developers often specialize in just one or two ecosystems.
• Data Architecture Skills: Determine if they need to write complex SQL/SOQL queries, build data warehouses, or use BI tools (like Tableau, Power BI, or Looker) integrated with your CRM.
• API and Integration Knowledge: They may need to pull data from external tools into your CRM or push CRM data out to a reporting layer.

2. Craft a Targeted Job Description

• Highlight the pain point: Explicitly state that the core responsibility is building robust, scalable custom reporting and dashboards that the native CRM lacks.
• Require platform certifications: For Salesforce, look for Platform Developer I/II or Certified Administrator; for Microsoft Dynamics, look for relevant Microsoft certifications.
• Ask for portfolio/case studies: Ask candidates to describe a complex reporting challenge they solved (e.g., multi-object reporting, historical data tracking, or automated executive dashboards).

3. Key Interview Questions to Ask

• "Can you walk me through a time you had to optimize a slow-loading report or a heavy database query in the CRM?"
• "How do you handle data cleanliness issues or missing fields when designing a mission-critical sales dashboard?"
• "How do you decide whether a report should be built natively inside the CRM versus exporting data to a separate BI tool?"

4. Run a Practical Assessment

• Give a small, timed technical test or a scenario-based exercise.
• Provide a sanitized, hypothetical data schema and ask them to outline how they would structure a complex commission or pipeline velocity report.

To help narrow down the search, could you tell me:

• Which CRM platform your team is using?
• Whether these custom reports need to stay inside the CRM or integrate with an external BI tool like Power BI or Tableau?

Hiring a great CRM developer requires looking past standard programming skills to find someone who deeply understands data architecture, business workflows, and your specific CRM platform (whether it is Salesforce, HubSpot, Microsoft Dynamics, or another tool).

Essential Steps to Hire a CRM Developer

• Define Your Scope First: Clarify whether you need a short-term custom report build, an ongoing administrator/developer hybrid, or a major data migration. Knowing the exact scope dictates whether you need a freelancer, agency, or full-time employee.
• Identify the Right Platform Expertise: CRM systems use proprietary languages (e.g., Apex for Salesforce, HubL/JavaScript for HubSpot, C#/.NET for Dynamics). Ensure candidates have direct experience with your specific ecosystem.
• Test for Business Logic, Not Just Code: A great CRM developer doesn't just write code; they understand why sales teams log data. Ask how they design data structures to minimize friction for end-users.
• Review Portfolio and Case Studies: Ask for examples of custom dashboards, automated workflows, or complex reporting objects they have built from scratch.
• Conduct a Practical Assessment: Give them a small, realistic scenario—like mapping out a custom attribution reporting requirement—to see how they translate business needs into technical architecture.

To help narrow down your search, could you tell me:

• Which CRM platform your team is currently using?
• What specific metrics or data sources your custom reports need to pull together?
• Are you looking to hire a full-time employee , a freelancer , or an agency?

Yes. For custom sales reporting, I’d hire for CRM architecture + data/reporting skills, not simply someone who calls themselves a “CRM developer.”

1. Define the problem before hiring

Write down 5–10 examples of reports your sales team needs, such as:

• Pipeline by rep, territory, product, and stage
• Win rate by lead source
• Sales-cycle length by segment
• Forecast accuracy
• Rep activity vs. closed revenue
• Conversion rates between pipeline stages
• Custom executive dashboards

Also specify where the data lives: CRM only, or CRM + ERP, billing, marketing automation, spreadsheets, etc. If the reports require combining multiple systems, you need someone comfortable with APIs/data integration—not just CRM configuration.

2. Look for these skills

A strong candidate should have:

Must-have

• Deep experience with your specific CRM (Salesforce, HubSpot, Dynamics, etc.)
• Data modeling and reporting/dashboard design
• CRM automation/workflows
• API and integration experience
• Ability to translate sales requirements into a technical solution
• Experience troubleshooting messy CRM data

For Salesforce, relevant skills include data modeling, automation, APIs/integrations, testing, and DevOps/CI/CD. trailhead.salesforce.com HubSpot similarly emphasizes APIs, custom CRM extensions, and integrations for more sophisticated development work.

Nice-to-have

• SQL/SOQL
• ETL/data warehouses
• BI tools such as Power BI or Tableau
• Git/version control
• Experience with your industry and sales process

3. Don't hire based on certifications alone

A certification proves familiarity with a platform; it doesn't prove they can design your reporting architecture.

Instead, ask candidates:

“Show me a complicated sales-reporting problem you've solved. What data did you need, where did it come from, how did you model it, and how did you make sure the numbers were accurate?”

Then ask for a sanitized example or demo.

A particularly good candidate will ask you questions about data definitions before proposing a solution. For example, they should clarify what your company means by “pipeline,” “qualified lead,” “closed won,” and “sales cycle.”

4. Give finalists a small paid test project

This is probably the best hiring filter.

Give them one real reporting requirement and limited access to a sandbox/test environment, then ask them to:

1. Examine the existing CRM data model.
2. Explain whether the report can be built natively.
3. Identify data-quality problems.
4. Propose an architecture if native reporting isn't sufficient.
5. Build a prototype.
6. Document how the sales team will maintain it.

Don't give them a huge unpaid take-home assignment.

5. Choose the right type of hire

For a handful of custom reports, I'd start with a freelance/contract CRM developer or specialized CRM consultancy, rather than immediately hiring a full-time developer.

You probably need a full-time person when the work expands into ongoing CRM ownership: integrations, automation, data governance, custom applications, reporting, and continuous development.

And there's an important distinction: if the problem is primarily reporting, you may actually want a CRM/RevOps analyst with strong technical skills rather than a software developer.

A good job description

I'd phrase the role roughly as:

CRM Developer / CRM Reporting Specialist
Build and maintain custom sales reporting, dashboards, CRM automation, data models, and integrations. Partner directly with Sales and RevOps to translate business requirements into reliable CRM solutions. Must have hands-on experience with [your CRM], complex reporting, data modeling, automation, APIs/integrations, and troubleshooting CRM data. Experience with SQL and BI tools is a plus.

If you tell me which CRM you use (Salesforce, HubSpot, Dynamics, Zoho, etc.), how many sales reps you have, and roughly what the custom reports need to show, I can give you a much more specific hiring profile—including where I'd look for candidates, interview questions, and what a reasonable contractor vs. full-time hire looks like.
