What a Machine Shop Quote Has to Capture
A CNC quote is a stack of small estimates: material (bar, plate or casting, with kerf and drop-off), setup time per operation, cycle time per piece, secondary operations such as deburr and inspection, outside processing (anodize, heat treat, plating, passivation), tooling and fixture cost, and a minimum lot or run charge. Software that only multiplies hours by a shop rate misses the lines where margin disappears: first-article inspection time, CMM programming, and outside process lead time. Whatever tool you pick must let you quote at several quantities, because the price break between 10 and 100 pieces is where customers decide.
- Material cost with stock size, kerf and remnant handling
- Setup and run time per operation, per work center rate
- Outside processing with vendor quotes and lead time
- Quantity breaks and minimum lot charges
- Tooling, fixturing and inspection programming as separate lines
ERP Estimating Modules: The Default Starting Point
If you already run JobBOSS, E2 Shop System, ProShop or Global Shop Solutions, the built-in estimate is the cheapest path, and it has one decisive advantage: an accepted quote converts into a job with the same routing, so estimated hours become the baseline for actual versus estimated tracking later. The weakness is that the estimate is only as good as the numbers estimators type in. Estimators often reuse an old quote from memory, and the ERP rarely warns that the last three runs of that part took 30 percent longer than quoted.
Treat the module as the system of record, not the source of the numbers.
Standalone Quoting Tools
Standalone quoting tools target the front end of the process: customers upload a STEP file or drawing, the tool estimates machining time from geometry, and an estimator reviews. They shine for high-mix, low-volume prototype work where geometry drives cost and customers expect fast, self-serve answers. Trade-offs to check: how the tool pushes accepted quotes into your ERP, whether it handles your materials and outside processes, whether you can tune its time model with your own actuals, and where uploaded files are stored.
If you hold ITAR or CUI drawings, ask exactly where the files and any AI processing live before anyone uploads a controlled part.

Where AI Drafting Fits
AI drafting sits between the RFQ email and the estimator. It reads the drawing and purchase order terms, finds similar past jobs in the ERP, pulls their actual hours and scrap, and drafts a quote with its sources shown. The estimator corrects and approves; nothing is sent or written back without a person.
Netray builds this kind of private AI over your ERP and documents, running open-weight models on your own hardware, so drawings stay inside your network. It is most useful when your history is deep, your estimators are the bottleneck, and your work repeats in families rather than being truly one of a kind.
When Software Will Not Fix Your Quoting
If you quote fewer than five jobs a week, a good template in your ERP and an estimator who checks past actuals will beat any new tool. If your shop rates are wrong, no software helps: recalculate your hourly rate per machine before evaluating anything. And if the real delay is waiting on vendor quotes for plating or heat treat, faster internal estimating only moves the queue.
Diagnose first: log, for ten quotes, how many hours each spent waiting versus working. That number tells you which category of software, if any, you actually need.
Frequently asked questions
What is the best quoting software for a small CNC machine shop?
For most small shops the best starting point is the estimating module in the ERP they already run, used consistently, with shop rates recalculated per machine. Standalone tools make sense for prototype-heavy shops with online customers. Pick based on quote volume and how well accepted quotes flow into jobs, not on feature lists.
Can quoting software calculate machining time from a CAD file?
Some tools estimate cycle time from STEP geometry using feature recognition and a time model. Accuracy depends heavily on your machines, tooling and fixturing, so the estimate is a starting point. Shops that tune the model with their own actual hours get far closer results than those who accept default rates.
Is it safe to upload ITAR drawings to a quoting tool?
Only if the vendor can show where files are stored, who can access them, and that processing stays within a US-persons-controlled boundary. Uploading export-controlled data to an uncontrolled cloud service can be an unauthorized export. Your own compliance officer should approve the setup before any controlled part is uploaded.
