How to Choose an ERP for a Small Machine Shop as the Owner

Signs You Have Outgrown QuickBooks and Spreadsheets

Spreadsheets work until the owner is the system. The signals are familiar: quotes live in individual estimators' files, you cannot compare quoted to actual hours, material is bought on a hunch, and customers call asking for status that someone must hunt down. Inspection records and certificates of conformance sit in folders that an auditor cannot navigate quickly.

Scheduling lives on a whiteboard and one person's memory. If a key employee leaving would stall the shop, it is time. Accounting software remains useful for the books, but it is not built for routings, work orders, lot traceability or shop-floor data.

• Quoted versus actual cost cannot be compared per job
• Status questions require a floor walk
• Customer audits expose scattered quality records
• Material shortages and late jobs are discovered too late

Write Down Your Flow Before You Look at Software

Describe in plain steps how work moves: RFQ intake, estimating, quote, PO review, job release, material purchase, outside processing such as anodize, plating or heat treat, machining operations, inspection and first article, shipping with certificates, invoicing. Mark where information is retyped, where you lose time and where customers or auditors ask for records. Then rank requirements: must-have, nice-to-have, not needed.

Job shops usually need quoting tied to routings, work orders and travelers, shop-floor data collection, scheduling with outside processing, material and lot traceability, inspection and nonconformance records, and customer-specific document handling. This list becomes the script for demos and reference calls.

Run a Demo on Your Own Jobs

Vendors will show their best data. Ask each to demonstrate with three of your real parts: one simple turned part, one multi-operation job with outside processing, and one repeat job with a revision change. Watch how a quote becomes a job, how a traveler prints, how a late job shows up, and how an operator reports time.

Ask how much configuration was needed for the demo and by whom. Ask for references from shops with similar size and work, such as JobBOSS, E2 Shop System, ProShop, Global Shop Solutions or Infor SyteLine users, and ask those references what went wrong and how long implementation really took.

Budget Money, Time and Your Own Attention

License or subscription is only part of cost. Include implementation and data migration, training, hardware such as shop-floor terminals or barcode scanners, integrations, support and the time of the people who must configure and learn it. Most small shops underestimate internal effort: someone must clean up item masters, routings and customer data, and run the old and new systems in parallel for a period.

Treat the owner's time as a real cost. Compare five-year total cost across candidates, not first-year price, and set a go-live goal that does not coincide with your busiest season or a major audit.

• Subscription or license, plus implementation and training
• Data cleanup and migration effort
• Terminals, scanners and network readiness
• Internal staff hours during parallel running

When a Heavier ERP Is Overkill, and Where AI Fits After

A ten-person shop with a few repeat customers may be better off with a lighter job shop system than a full enterprise ERP with modules it will never use. Choose the simplest system that closes your real gaps and can grow. Once data is clean, AI becomes more useful because it can answer questions over your own history: how long did this part take last time, which jobs are late, which customers have the lowest margin.

Those assistants work best on top of a system of record with disciplined data, so fix the foundation first.
