I'm looking for a simple quoting software for our service business that's easy to use on the go.

When you are running a service business on the move, you need an app that lets you build, price, and text/email a professional quote before you even step back into your truck—without getting bogged down by clunky desktop software.

Depending on how "simple" you want to go (purely fast estimates vs. light field-service management), here are the top options tailored for mobile use:

1. Best for Pure Speed & Simplicity: Invoice Simple

• The Vibe: Exactly what it sounds like. It strips away complicated accounting and heavy CRM bloat.
• Mobile Experience: Highly rated iOS and Android apps that let you whip up an estimate or quote in under a minute.
• Key Features: Turn estimates into invoices with a single tap, save recurring clients and line-item services, and capture customer signatures right on your phone screen.
• Best for: Solopreneurs or small mobile crews who just want to get quotes out and get paid fast without a learning curve.

2. Best Built-For-Mobile Field Service: QuoteIQ

• The Vibe: Built specifically by operators in the field, prioritizing a fast mobile-first workflow.
• Mobile Experience: Designed from the ground up for smartphones, featuring quick-estimate calculators for small jobs and AI-assisted pricing.
• Key Features: Instant quote generation, built-in price books with margins, automated quote follow-ups (crucial for closing deals on the spot), and route optimization to manage your day.
• Best for: Hands-on service contractors (landscaping, mobile detailing, pressure washing, handymen) working out in the field.

3. Best Popular All-In-Ones (Slightly More Robust): Jobber or House Call Pro

• The Vibe: Industry standards for field service. They are heavier than Invoice Simple, but their mobile apps are polished if you want scheduling and dispatching tied to your quotes.
• Mobile Experience: Excellent mobile apps, though best utilized if you want customers to approve quotes via an online client portal.
• Key Features: Professional customizable quoting templates, job scheduling, automated text reminders, and easy credit card processing on-site.
• Best for: Growing service businesses that want quotes to seamlessly turn into scheduled jobs and invoices in one ecosystem.

To help narrow it down, tell me:

• What specific type of service business do you run?
• Do you just need estimates and invoices , or do you also need scheduling and dispatching for a team?

If your main goal is “I’m at the customer’s property, I need to make a professional quote quickly from my phone”, I’d keep the shortlist pretty small.

My top picks

• joist.com — simplest option. Best if you mainly need estimates, invoices, deposits/payments, and basic customer/job records. It’s mobile-first and starts around $10/month.
• getjobber.com — best overall for a growing service business. It gives you professional quotes, online approvals/deposits, scheduling, invoicing, payments, and follow-up. Current entry pricing is around $49/month.
• housecallpro.com — best if you want quoting plus more field-service automation. Strong mobile workflow, scheduling/dispatch, payments, customer communication, and flat-rate estimating. It costs more, starting around $59–$79/month depending on plan/billing.

What I'd choose

If you're a small business and primarily want quoting: Joist.

If you want the quoting system to eventually handle your whole operation: Jobber.

If you have technicians/crews and need dispatching and stronger field-service features: Housecall Pro.

The big question is whether you need just quotes/invoices or quotes → customer approval → scheduling → job → invoice → payment. If you tell me what type of service business you run and roughly how many people are in the field, I can narrow it down to the best 1–2 options for you.

For a service business that needs to fire off estimates and quotes from a phone or tablet while sitting in the truck or standing at a client's kitchen table, you want something mobile-first , fast, and uncluttered.

Here are the best, easiest-to-use options broken down by what style of business you run:

• Invoice Simple — The absolute fastest, most polished phone experience for typing up a quick line-item estimate on the fly. It's built strictly for speed, lets you text or email a clean PDF quote immediately, and converts it to an invoice with one tap once the client says yes. Check it out on Invoice Simple.
• Square Invoices — Best if you want to seamlessly bundle your quoting with on-the-spot mobile payments. You can build and send a professional estimate from the Square Invoices mobile app , the client clicks 'approve' right from their phone, and you can swipe or tap a card right there when the work is done.
• Housecall Pro — Best if you run a home/field service business (plumbing, HVAC, cleaning, landscaping) and want room to grow. It’s a bit more robust than a basic receipt app, but their Housecall Pro Mobile App makes it ridiculously easy to pull up customer history, click-and-send customized quote templates, and capture digital signatures on the spot.
• Invoice2go — A fantastic, lightweight mobile app designed for contractors and sole operators on the move. It lets you spin up a professional estimate in under a couple of minutes and even gives you read-receipt notifications so you know the exact moment your client opens your quote. Explore features on Invoice2go.
• Zoho Invoice — The top pick if you are looking for a completely free tier that doesn't restrict how many core documents you send. It has a reliable mobile companion app and handles the full estimate-to-invoice workflow smoothly, though the interface feels a bit more traditional/desktop-derived than the others. Learn more at Zoho Invoice.

To help narrow this down, let me know:

• What type of service business do you run (e.g., contracting, mobile detailing, consulting)?
• Do you need to collect credit card payments directly from the quote, or just send the estimate?

If you want something simple, mobile-friendly, and built for a service business, I’d focus on tools that let you create a quote while you’re at the customer’s site, send it by text/email, and ideally turn it into an invoice later.

Here are some good options:

A quick way to choose:

• Just need to make quotes quickly from your phone: QuoteKit or QuoteMe.
• Need quotes + scheduling + customer history: Jobber or Housecall Pro.
• Need a professional-looking quote approval process: TapQuote.
• Have a small crew and want everything connected: Runly.

If you tell me:

1. what type of service business you run (cleaning, HVAC, landscaping, remodeling, etc.),
2. how many people are on the team, and
3. whether you need invoices/payments or only quotes,

I can narrow it down to the best 2–3 options.

If your main priority is “I’m standing in front of a customer and need to build/send a quote from my phone quickly,” I’d narrow it to three:

*Pricing changes, so I'd verify the current plan before signing up. Current 2026 comparisons put Joist at the low end and Jobber/Housecall Pro higher as you add scheduling, CRM, and team functionality.

My pick: Joist

If by “simple” you mean quotes are the primary thing you need, I'd start with Joist. It's specifically designed around creating estimates on a phone, with line items, photos, markups, deposits, invoices and payments. You can go from estimate → invoice without adopting a giant field-service-management system.

The tradeoff is that Joist doesn't give you much scheduling/dispatch/CRM functionality. If you expect to grow into multiple technicians and want the quoting system connected to the rest of the business, I'd look at Jobber instead.

If you want something that grows with the business

Jobber would be my second choice. Its mobile app lets you create quotes on-site, including from templates, and it connects quoting with scheduling, customer management, invoicing and payments.

Housecall Pro is worth considering if you're running a home-service operation with technicians. It's more of an all-in-one field-service platform, with quoting, scheduling, dispatch, payments and customer communication.

Bottom line:

• Solo/small service business + primarily need quotes: Joist
• Need quotes + scheduling/CRM: Jobber
• Multiple techs + full field-service operation: Housecall Pro

If you tell me what type of service business you run, how many people are in the field, and whether you need invoicing/payment collection too, I can narrow this down to the 2 best options and compare their actual costs/features for your situation.

When you need to quote on the go, you want an app that lets you punch in a few line items, attach a site photo , and text or email a professional PDF before you even pull out of the driveway.

Here are the best simple, mobile-friendly quoting and estimating options tailored for service businesses, broken down by how they work:

• Joist — Best for pure, straightforward estimates. Joist is widely loved by solo operators and small trade crews because it isn't bloated with heavy management tools. You can build itemized estimates, add notes or photos, collect digital signatures, and quickly convert approved quotes into invoices right from your phone. It offers a solid free tier to test out.
• Jobber — Best for a smooth transition from quote to schedule. If quoting is just the first step before booking a job, Jobber's mobile app is exceptionally polished. It allows you to create great-looking quotes with optional upsell packages, triggers automated follow-ups if the client doesn't reply, and lets customers approve quotes online through a self-serve portal.
• Billdu — Best for phone-first invoicing and basic expenses. Billdu is designed specifically as a light, mobile-first layer for entrepreneurs who need to generate fast estimates and invoices without dealing with heavy corporate accounting software. The app runs smoothly on iOS and Android, keeping client info and document tracking right in your pocket.
• Square Invoices — Best if you already use Square for payments. If you want an all-in-one app with no extra monthly software fees just to send basic paperwork, Square lets you send free estimates from your mobile device and instantly convert them into payable invoices the second the client gives the green light.
• Contractor+ — Best all-in-one mobile estimator. Built specifically for field service and contracting work, it packs estimates, line-item pricing, a client CRM, and a free entry tier into a fast mobile app designed for on-site use.

To help narrow down the best fit, tell me:

• What specific type of service do you provide (e.g., cleaning, contracting, landscaping, consulting)?
• Do you need to schedule the job and invoice from the same app, or just send the quote?

When you are running a service business on the move, you want an app that lets you pull out your phone at a client's kitchen table or job site, tap in a few numbers, and text or email a clean, professional quote before you even walk to your truck.

The best "dead-simple" mobile quoting and estimating tools focus on speed, e-signatures, and one-tap conversion into invoices without forcing you to learn a bulky enterprise CRM:

• Invoice Simple - Best for absolute simplicity. It is designed specifically for creating fast estimates and mobile invoices. You can save standard service items, autofill repeat clients, and text or email a PDF quote with a tap.
• Joist - Best for contractors and field services. It lets you build itemized estimates with material and labor costs right from your phone, get client sign-off on the spot, and turn approved quotes into invoices instantly.
• Square Invoices - Best if you want integrated payments. It offers a very clean mobile app where you can send free estimates and seamlessly convert them into payable invoices with a built-in "Pay Now" button, operating on a pay-as-you-go processing structure.
• QuoteIQ - Best for field service speed. It is built for small service crews who want fast local estimating, digital contracts, and quick turnarounds from estimate to paid invoice without heavy software bloat.
• FreshBooks - Best if you need light accounting too. While it’s a bit more fully-featured, its mobile app makes generating and tracking estimates on the go exceptionally smooth and converts billable time or materials straight into invoices.

If you can tell me your specific trade or service (e.g., landscaping, cleaning, handyman, mobile repair) and whether you need it to sync with accounting software like QuickBooks , I can narrow this down to the exact best match for your workflow.

If your main goal is “I’m at the customer’s house, I want to make a quote in a couple minutes and send it from my phone,” I’d keep the shortlist pretty small:

My pick: Joist

For the wording “simple quoting software”, I'd start with Joist. It seems deliberately designed around the quote → approval → invoice → payment workflow rather than trying to become your entire business-management system. It also offers a 14-day trial with no credit card required.

If you have multiple technicians and need scheduling/dispatching, I'd move up to Jobber or Housecall Pro.

If you tell me what type of service business you run, how many people are in the field, and roughly how many quotes you send per week, I can narrow this down to the best 1–2 options and compare their current pricing.

If your main need is “I’m at the customer’s house, build a quote on my phone, send it, and move on,” I’d keep the shortlist pretty small:

My pick

Start with Joist if you don't need complicated scheduling/dispatch. It's specifically designed to get a contractor from estimate → approval → invoice → payment without turning into a giant field-service-management system.

If you have multiple technicians and need scheduling/dispatch, I'd move up to Jobber or Housecall Pro.

If you tell me what kind of service business you run, how many people are in the field, and roughly how many quotes you send per week, I can narrow it down to the 2 best options and compare their current pricing/features.

When you are running a service business from the field, you need an app that lets you punch in a few numbers, attach a site photo , get a digital signature, and email a clean PDF before you even back out of the client’s driveway.

The best mobile quoting tools tailored for speed, simplicity, and on-the-go use are categorized below by how they fit a service workflow:

• Joist — Best for pure, straightforward speed. Joist is built explicitly for quick, clean estimating and invoicing on iOS and Android. It features a solid free tier, an item/price list library, and lets clients sign off digitally right on your phone or tablet. It doesn't bog you down with heavy dispatching or complex accounting structures.
• QuoteIQ — Best for contractors and home service pros. QuoteIQ is a mobile-first app designed by people in the field. It stands out for on-the-go features like good/better/best options pricing tiers, instant PDF generation with photo attachments, and satellite property measurement tools so you don't have to manually pace out a site. It also handles one-tap conversion from quote to invoice.
• Contractor+ — Best all-in-one mobile command center. If you want quoting to flow seamlessly into scheduling, client management (CRM), and payment collection without sitting at a desktop, Contractor+ offers a robust mobile experience with a generous entry-level free tier.
• Square Invoices — Best for zero monthly fees and simple billing. If your primary goal is to send a quick digital estimate and turn it into a payment-processing invoice the second the client says yes, Square’s mobile app is completely free to use (you only pay standard processing fees when they pay).
• Jobber — Best if you plan to grow a team. If you are a solo operator right now but plan on adding field techs or dispatching crews soon, Jobber has a stellar mobile app that bridges quick on-site quoting with robust scheduling and job tracking.

• Are you looking for a completely free starter option or a paid professional tier?
• Do you need it to integrate with an existing accounting tool like QuickBooks?
