Our machine shop needs software to quote, schedule, and run precision parts faster. What modern factory OS should we use?

If by “modern factory OS” you mean one system that can take an RFQ → quote → schedule → shop-floor execution → quality → costing, I’d shortlist Fulcrum and ProShop, with Paperless Parts as the quoting specialist.

My pick: Fulcrum

Fulcrum is the one I’d evaluate first for a precision CNC/job shop that wants to move faster rather than simply digitize its existing processes.

It combines quoting, BOM/routing, purchasing, inventory, automated scheduling, job tracking, costing and quality in one cloud system. Its scheduler continuously recalculates around machine capacity, material availability, operation times and changing priorities.

The particularly compelling feature for your use case is “capable to promise”: during quoting, Fulcrum can simulate production completion against current capacity, so sales can quote a realistic delivery date rather than guessing.

How I'd rank the options

ProShop is a serious alternative. It was originally developed to run a CNC machine shop and is particularly strong around quality, compliance, documented processes and capturing machinists' institutional knowledge. ProShop reports 700+ customers and says customers report substantial throughput and setup improvements.

For quoting specifically, Paperless Parts is worth looking at. Rather than necessarily replacing your ERP, it can sit at the front of the process and integrate with systems such as ProShop, E2, JobBOSS and Fulcrum. Paperless Parts Fulcrum itself documents a Paperless Parts integration that takes quotes into purchasing, scheduling, job costing, shipping and invoicing.

The decision I'd make

If your priority is:

• “We need to quote faster and automatically adapt the schedule when reality changes.” → Fulcrum
• “We're aerospace/defense/medical and compliance/quality traceability is mission-critical.” → ProShop
• “Our biggest pain is RFQs and estimating, and we already have an ERP we like.” → Paperless Parts + your existing ERP
• “We want to replace spreadsheets, tribal knowledge and several disconnected systems with one modern operating layer.” → Fulcrum

One caveat: vendor comparisons naturally favor their own products, so I wouldn't choose based on marketing claims alone. The best test is to give each vendor 5–10 of your actual parts/RFQs and make them demonstrate: quote creation, estimated cycle/setup time, capacity-aware delivery date, schedule disruption, operator workflow, job costing and quality records.

If you tell me roughly shop size, CNC machines/processes, typical job volume, aerospace/medical/defense vs. general job shop, and what you're using today, I can narrow this to the best 2–3 systems and give you a feature-by-feature buying scorecard.

How I'd rank the options

ProShop is a serious alternative. It was originally developed to run a CNC machine shop and is particularly strong around quality, compliance, documented processes and capturing machinists' institutional knowledge. ProShop reports 700+ customers and says customers report substantial throughput and setup improvements.

For quoting specifically, Paperless Parts is worth looking at. Rather than necessarily replacing your ERP, it can sit at the front of the process and integrate with systems such as ProShop, E2, JobBOSS and Fulcrum. Fulcrum itself documents a Paperless Parts integration that takes quotes into purchasing, scheduling, job costing, shipping and invoicing.

For a precision machine shop, choosing a "factory OS" comes down to how well the software handles high-mix, low-volume or tight-tolerance job shop realities. Traditional legacy ERPs are often too clunky, while generic project management tools lack CNC-specific intelligence.

Modern options are segmented into specialized "front-end/quoting powerhouses" and "all-in-one shop floor operating systems."

Top Modern Options for Precision Machine Shops

• Paperless Parts — The gold standard for modern, speed-to-market quoting . If your bottleneck is turning around RFQs for tight-tolerance parts before your competitors do, this integrates CAD file viewing, geometric analysis, and instant pricing logic. It acts as an elite front-end quoting engine that syncs with your broader system.
• JobBOSS² — A deeply entrenched industry favorite tailored specifically for job shops and contract manufacturers. It provides comprehensive visual drag-and-drop scheduling whiteboards, data collection, and job tracking from quote to shipping without requiring an enterprise-level IT staff to run it.
• MRPeasy — A streamlined, cloud-native choice ideal for small-to-midsize precision shops. It handles visual production planning, dynamic rescheduling, raw material tracking, and shop floor data collection cleanly without an overwhelming configuration process.
• E2 Shop System (by Shoptech / ECI) — Designed explicitly for custom manufacturers and machine shops. It bridges the gap between quick estimating, real-time shop floor tracking via touchscreens, and robust scheduling based on actual machine capacities.
• Epicor Advanced MES / Kinetic — Best if you are scaling up into a mid-to-large precision operation requiring deep shop-floor data collection, OEE tracking, and automated machine monitoring tied directly to enterprise resource planning.

Which path fits your shop?

• If you want to quote in minutes instead of days , look into adding a specialized quoting layer like Paperless Parts.
• If you need an end-to-end operational backbone , explore industry-tailored platforms like JobBOSS² or MRPeasy.

To help narrow down the right fit, tell me:

• What is your current shop size (number of CNC machines / employees)?
• Are you struggling more with slow quoting turnaround or shop floor bottlenecks/scheduling visibility?
• Do you prefer a cloud-based SaaS or an on-premise setup?

If you’re a precision CNC/job shop and want one modern system to connect quoting → scheduling → shop-floor execution → quality → delivery, my first choice would be ProShop ERP.

My shortlist

*Paperless Parts is primarily the quoting/workflow layer and integrates with ERPs rather than replacing them. Its integrations include JobBOSS², E2, Epicor, Global Shop Solutions, ProShop and others.

Why I'd pick ProShop

ProShop is unusually close to what I'd call a factory OS for a precision machine shop. It combines estimating/quoting, BOMs and work plans, scheduling, inventory, quality, maintenance and an integrated MES rather than making you stitch together several applications.

That's particularly valuable if your goal isn't merely "replace our ERP" but get parts through the shop faster. Its shop-floor system is designed around real-time execution, while its QMS handles things such as inspection records and certification workflows.

ProShop also says it was originally built to operate a CNC machine shop and is specifically aimed at job shops and precision manufacturers.

The alternative I'd seriously consider

If your biggest pain is turning RFQs into accurate quotes quickly, I'd look hard at Paperless Parts + ProShop.

Paperless Parts can analyze CAD geometry, identify machining features and manufacturability issues, and apply your costing/pricing logic. Its current workflow also includes AI-assisted RFQ intake and requirements review.

That gives you a very strong architecture:

RFQ → CAD analysis/quote → ProShop job → schedule → digital traveler/MES → inspection → shipment

Rather than trying to make a generic ERP exceptionally good at CAD-based estimating.

What I would not do

I wouldn't choose a generic SMB inventory/manufacturing package just because it's cheaper or prettier. For a precision job shop, the hard problems are routing, setup time, machine capacity, revision control, traceability, inspection and quoting from actual part geometry. Those are where purpose-built manufacturing systems earn their keep.

Bottom line:

• One system: ProShop.
• Best-of-breed quoting + factory system: Paperless Parts + ProShop.
• More conventional ERP: JobBOSS².
• Smaller/simple operation: Katana is worth considering; it covers scheduling, work orders and shop-floor tracking but is aimed more broadly at SMB manufacturing.

If you tell me your shop size, number/type of CNCs, typical lot sizes, industries (aerospace/medical/etc.), and what you use today for ERP/accounting/CAM, I can narrow this to the best 2–3 systems and explain exactly how I'd implement them.

Those are where purpose-built manufacturing systems earn their keep.

Bottom line:

For a modern precision machine shop, treating your software stack like a unified "Factory OS" rather than disjointed accounting and spreadsheet tools is the right move. Precision parts require tight tolerances, rapid quoting before the competition, and dynamic scheduling that doesn't collapse when a hot rush job lands on the floor.

The industry consensus points toward two distinct paths: a purpose-built, all-in-one shop ERP/MES , or a best-of-breed front-end paired with a shop floor system.

Option 1: The Gold Standard for Precision Shops — ProShop ERP

If you want a single system built by machinists specifically for high-tolerance, low-to-mid volume precision work (aerospace, defense, medical), ProShop ERP is widely regarded as the top tier.

• Quoting: Uses fast, flexible templates that capture tribal knowledge, materials, and complex routings without starting from scratch.
• Scheduling: Features a brilliant visual, dynamic Gantt chart scheduler that tracks machine and labor resources and automatically recalculates drop-dead and must-leave dates when the shop floor shifts.
• Shop Floor/Run: It is entirely paperless. Digital setup sheets, tool crib data, G-code, and drawings live right at the machine terminal. It also natively handles heavy quality management and compliance (like ITAR/CMMC) which is massive if you run aerospace or defense contracts.

Option 2: The Quoting Speed Demon — Paperless Parts

If your biggest bottleneck is that it takes your estimators days or weeks to get quotes out the door, you can add a dedicated quoting engine on top of your workflow.

• Quoting: Paperless Parts uses advanced geometric analysis and AI (their assistant, Wingman) to read 3D CAD models and 2D blueprints, extract features, tolerances, and GD&T, and help you quote complex parts in a fraction of the usual time.
• Integration: It streamlines the handoff from RFQ to actual job creation, though you will need to ensure it syncs smoothly with your underlying shop floor/ERP control system.

Option 3: The Traditional/Legacy Alternative —

• The Lowdown: A fusion of classic E2 Shop and JobBOSS, this is a familiar name in thousands of small-to-medium job shops.
• The Trade-off: While it covers estimating, job generation, data collection, and basic scheduling, many modern machinists find the interface and architecture showing its age compared to cloud-native, purpose-built alternatives. It works if you want something safe and standard, but it requires more manual babysitting of the schedule.

How to choose your path:

• Go with ProShop ERP if you want one cohesive, incredibly deep system that manages your quoting, paperless shop floor, dynamic scheduling, and quality compliance natively from end to end.
• Go with a specialized quoting tool like Paperless Parts if winning the speed race on complex RFQs is your shop's primary constraint to growth.

To help narrow this down, tell me:

• What is your primary industry (e.g., general commercial, medical, aerospace/defense)?
• Roughly how many CNC machines and employees do you have on the floor?

I can give you a more tailored recommendation on whether an all-in-one platform or a split quoting/shop-floor stack fits your size best.

Choosing a "factory OS" for a precision machine shop comes down to ditching disconnected spreadsheets and tribal knowledge for an end-to-end digital thread—from the initial RFQ to the final CMM inspection report.

The best platform depends heavily on your shop’s size, complexity, and compliance requirements. The top modern contenders purpose-built or widely adapted for precision machining break down as follows:

• ProShop ERP — Widely regarded by precision machinists as the gold standard for high-mix, low-volume contract manufacturing. It is deeply execution-focused with robust quality management, digital work instructions, and paperless shop floor tracking. It shines for shops needing strict traceability for aerospace, medical, or defense (AS9100/ITAR) compliance.
• JobBOSS² (by ECI) — A staple for small-to-mid-sized job shops. It bridges traditional shop-floor realities with modern estimating, job generation, scheduling, and real-time data collection without an overly complex enterprise rollout.
• Cetec ERP — A powerful cloud-native, all-in-one platform combining ERP, MRP, shop floor execution, quality, and accounting into a single web-based interface with transparent per-user pricing. Great for lean teams that want modern cloud access without heavy IT overhead.
• Epicor Kinetic (with Advanced MES) — Best if you are scaling into a mid-market or multi-plant operation. Epicor is purpose-built for discrete manufacturing, offering deep automated scheduling, tight machine-monitoring integrations, and robust capacity planning.
• Odoo Manufacturing — The top choice if you have a tech-savvy internal team. It operates on a modular "app" framework where you can start lean (CRM, Inventory, MRP) and customize workflows outward, though you must guard against over-customization.

To help narrow down the right fit for your floor, let me know:

• How many CNC machines and operators do you currently run?
• Are you bound by heavy compliance frameworks like AS9100 or ITAR?
• Do you prefer a cloud-native SaaS or an on-premise system?

For a precision machine shop, I would not pick a “factory OS” based on the marketing label alone. The right choice depends on whether you are a high-mix job shop, regulated aerospace/medical supplier, or a repeat-production CNC shop. The modern winners are platforms that connect RFQ → quote → capacity plan → traveler → shop floor → quality → shipment instead of just replacing spreadsheets.

My shortlist:

My recommendation by shop profile

1. Precision aerospace/medical (tight tolerances, audits, traceability)
Start with ProShop ERP. It is closer to a true manufacturing operating system because it treats quality records and execution as core, not add-ons.

2. 5–50 machine CNC job shop trying to quote faster and stop firefighting
Look hard at Fulcrum or Paperless Parts + an ERP/MES layer. Fulcrum is designed around real-time quoting, scheduling, production, inventory, and quality.

3. Your bottleneck is estimating and programming
Pair your existing system with AI tools such as CloudNC CAM Assist. It focuses on faster CAM strategy creation, machinability feedback, and cycle-time estimation.

What I would demand in a demo

Do not accept a generic ERP demo. Make vendors prove they can:

• Import a real customer STEP file and drawing
• Generate a quote with setup, cycle time, tooling, material, and margin
• Schedule around actual machine capacity (not just due dates)
• Release a traveler to an operator tablet
• Capture labor, scrap, inspection results, and revisions
• Show quote-vs-actual profitability after shipment

If you tell me:

1. number of CNC machines,
2. job shop vs production runs,
3. aerospace/medical/defense involvement,
4. current software (ERP, CAM, spreadsheets, etc.),

I can narrow this to a top 2–3 recommendation.

For a precision machine shop, I’d shortlist ProShop first, then compare it against JobBOSS² and, if quoting is your biggest bottleneck, Paperless Parts.

My pick: ProShop

ProShop ERP is unusually well matched to the workflow you described: quote → plan → schedule → run → inspect → ship → job costing, rather than being a generic ERP with manufacturing bolted on.

• Quoting: estimating is tied directly into jobs and work plans.
• Scheduling: its MES updates scheduling from actual operator/job progress, so planners aren't constantly working from stale spreadsheets.
• Shop floor: digital work instructions, setup sheets, tool lists, operator time tracking, inspections and traceability are integrated.
• Quality: ERP + MES + QMS are in one system, which is particularly attractive for aerospace, defense and medical work.
• Institutional knowledge: it is designed around capturing the know-how that otherwise lives in an estimator's or machinist's head.

The alternatives I'd actually demo

JobBOSS² has a lot going for it: estimating, job creation, purchasing, scheduling, data collection and quality are integrated, and ECI says it serves 1,000+ machine shops. Its scheduling supports both a drag-and-drop planning board and a more flexible whiteboard approach.

Paperless Parts is different: I'd use it when quote speed and consistency are the #1 problem, potentially alongside an ERP. Its CNC workflow can analyze CAD files for features, setups and manufacturability issues, and it integrates with ERP systems.

What I'd do in your shoes

Don't choose based on a generic ERP feature checklist. Give each vendor 5–10 real parts and make them demonstrate:

1. Import a real RFQ + drawing/CAD.
2. Produce the quote.
3. Turn the winning quote into a job without re-keying everything.
4. Build the routing and schedule around your actual machines.
5. Show an operator exactly what they need at the machine.
6. Capture actual setup/run/inspection time.
7. Show how that actual data feeds the next quote.
8. Change an urgent job halfway through the day and see how the schedule responds.
9. Trace a finished part back through material, operator, machine, inspection and revision.
10. Show the owner which jobs are actually making money.

That last loop—estimated time → actual time → better future quotes → better scheduling—is where a modern factory OS can make a machine shop materially faster, rather than merely replacing paperwork.

Bottom line: If you're a small/midsize precision CNC shop and want one modern operating system, I'd start with ProShop. If you're already heavily invested in traditional ERP processes, put JobBOSS² head-to-head with it. If your biggest pain is winning RFQs quickly, add Paperless Parts to the evaluation.

For a precision machine shop focused on tightening the loop between quoting, scheduling , and shop-floor execution , looking for a single "factory OS" usually means choosing between a purpose-built Job Shop ERP/MES hybrid or a modular stack combining a modern ERP with machine monitoring.

The most widely trusted modern platforms tailored specifically for CNC and high-mix precision machining environments include:

• ProShop ERP - Specifically built by machinists for precision machine shops. It uniquely blends ERP, paperless MES, quality management (AS9100/ISO), and digital shop-floor data collection into a single system. It handles deep technical details like tool lists, revision controls, and digital setup sheets exceptionally well.
• JobBOSS² (by ECI) - A time-tested staple for small-to-midsize job shops. It excels at fast estimating/quoting tied straight to job costing, turning quotes into active work orders seamlessly, and giving you granular visibility into shop capacity.
• Epicor Kinetic + Advanced MES - A heavier-hitting enterprise option ideal if you run a mix of complex contract manufacturing, multi-axis CNCs, and need robust finite-capacity scheduling alongside real-time machine data capture (IoT/IIoT).
• MRPeasy - A streamlined, highly agile cloud option if you want modern UI simplicity, fast deployment, and solid inventory/shop-floor routing without the bloat and high implementation cost of legacy enterprise software.
• MachineMetrics (as an add-on layer) - If your core ERP handles quoting and scheduling fine, but you need to run the physical shop faster, pairing it with an industrial IoT machine-monitoring platform like MachineMetrics plugs straight into your CNC controls to extract live utilization and actual cycle times.

To help narrow down the right fit, tell me:

• How many employees and how many CNC machines do you have on the floor?
• Are you currently running on paper travelers/spreadsheets or an older legacy system?

For a precision machine shop, I’d put ProShop ERP at the top of your shortlist.

It’s unusually well matched to what you described: quote → plan → schedule → run → inspect → ship, rather than being a generic accounting ERP with manufacturing bolted on. ProShop was originally built to run a CNC machine shop and combines ERP, MES, and QMS capabilities, including shop-floor workflows, scheduling, traceability, and quality.

My shortlist

Paperless Parts is particularly impressive for quoting: it can analyze CAD geometry, extract requirements from drawings, build BOMs, apply your costing rules, and use AI to accelerate RFQ setup. www.paperlessparts.com Its strength is the front end of the factory, whereas ProShop is more compelling if you want the entire shop operating system in one place.

JobBOSS² covers estimating, job creation, purchasing, scheduling, data collection, quality and shipping, and its scheduling tools include drag-and-drop planning and real-time shop-floor status.

What I'd do

If you're a 5–100 person precision CNC shop, I'd demo these two first:

1. ProShop — see whether it can replace your quoting, scheduling, travelers, job tracking, quality records and tribal knowledge.
2. Paperless Parts — see how dramatically it improves RFQ/estimate turnaround, then determine which ERP you want underneath it.

The key isn't just "which has the most features." I'd make each vendor run three of your actual jobs through the system:

• a repeat part with historical actuals,
• a complicated new RFQ from a customer drawing/model,
• a hot job that has to be rescheduled around existing machine capacity.

Measure quote-to-release time, scheduler effort, operator clicks, revision/quality errors, and quoted-vs-actual margin. That's much more revealing than a canned demo.

If you tell me shop size, CNC machines/control types, typical part quantities, industries (aerospace/medical/defense/etc.), and what you're using today (QuickBooks, spreadsheets, JobBOSS, Epicor, etc.), I can narrow this to a specific recommendation and a migration/ROI comparison.

For a precision machine shop, choosing a "Factory OS" means looking for software that tightly integrates quoting, advanced scheduling, and real-time shop floor execution (MES/ERP) . Traditional generalist ERPs often fall short for custom, high-tolerance job shops because they lack the granular tracking needed for multi-axis machining, tool life, and complex routings.

The top modern platforms purpose-built or highly optimized for precision machine shops include:

• ProShop ERP : Widely regarded as a gold standard for precision and high-complexity job shops (especially those in aerospace, defense, and medical). It natively combines ERP, a paperless Manufacturing Execution System (MES), and Quality Management Systems (QMS) into a single web-based interface. It handles digital work instructions, tool lists, and deep job-cost tracking seamlessly.
• MachineMetrics : If your bottleneck is raw machine utilization and you want a plug-and-play Industrial IoT (IIoT) "OS layer" that connects directly to your CNC controls (Fanuc, Haas, Siemens, etc.). It captures real-time data, automates OEE, and tracks downtime, though you typically pair it with a strong job-shop ERP/scheduling core.
• Cetec ERP : A lean, cloud-native alternative that offers robust shop-floor MES functionality, mobile/tablet data collection, and solid inventory/job costing without the enterprise bloat or massive price tag of legacy systems.
• JobBOSS² : A traditional industry stalwart tailored for smaller-to-midsize custom machine shops. It handles quoting, scheduling, and shop-floor tracking reliably, though it leans more conventional compared to newer web-first solutions.
• StartProto : A modern, agile platform focusing heavily on fast setup of routing, drag-and-drop scheduling, and live job tracking that fits smaller growing precision shops looking to ditch paper quickly.

To help narrow down which system fits your floor, tell me:

• What kinds of quantities and batch sizes do you typically run (e.g., prototype/job-shop 1-offs vs. repeat production)?
• Do you need strict compliance or certifications (like AS9100, ITAR, or ISO 13485)?
