How to sell a machine shop, and which of its records are yours to license

How do you sell a machine shop?

You sell a machine shop by showing a buyer durable earnings: diversified customers, repeatable work, documented processes and equipment that is maintained rather than worn out. A broker or M&A advisor usually runs a confidential process; the owner prepares financials, a machine list and a plan for staying on through a transition.

This guide covers buyers, the numbers they test and the shop floor items that move price. It also covers one question that most sale guides skip: which of the shop's records belong to the shop and could be licensed, as opposed to customer drawings that do not.

Who buys machine shops?

Our guide to building an M&A buyer list shows how to rank these by likelihood and where AI data buyers fit next to acquirers.

What drives machine shop value?

Buyers look past the equipment list to the quality of the revenue.

1. Customer concentration: a shop with one customer above a third of revenue is priced for risk. Document the relationship, contract terms and history of repeat orders.
2. Work mix: repeat production runs with blanket purchase orders read better than one-off prototypes. Show win rates on quotes.
3. Certifications: ISO 9001, AS9100, ITAR registration or NADCAP approvals, where relevant to your customers, are slow to earn and hard to replace.
4. Equipment and maintenance: list each machine by make, age, hours and maintenance log. Deferred maintenance becomes a price adjustment.
5. People: programmers, setup machinists and the quality manager hold tacit knowledge. Buyers ask which of them are staying and on what terms.
6. Systems: the ERP or job-costing tool, CAM software and quoting process show whether the shop runs on process or on the owner's memory.

The shop-floor readiness checklist

• Three years of job-level margin, not just shop-wide margin.
• Quote log with win and loss reasons.
• Machine list with age, hours, service records and utilization.
• Current quality manual, audit results and corrective action history.
• Routings, setup sheets and inspection plans stored where they can be exported.
• Written transition plan for the owner, programmer and quality lead.
• Clear note on which files are customer property and which are shop property.

Which records belong to the shop and which do not?

This is where machine shops differ from most businesses. A customer's drawing, model or specification is normally the customer's, or covered by an NDA, and a shop should not license it. Our explainer on who owns customer drawings at a contract manufacturer walks through the question.

The shop's own operating records are a different class.

Even shop-owned records often mention customer names, part numbers or specifications. Redaction rules are agreed with the company before any work begins, and nothing is delivered without an executed agreement and the company's authorization. Defense or export-controlled work is a clear reason to stop and take advice first.

When should you start, and what happens at each stage?

Start 12-18 months ahead if you can. Shops with lumpy years or an owner who runs every quote need the most lead time.

Buyers often ask for customer calls late in the process. Choose the order carefully with your advisor, since an early call can disturb a relationship before the buyer is committed.

How does a data license interact with the sale?

The shop keeps ownership: the records are licensed, not sold, and deals are typically exclusive for AI training for an agreed term. That term is the part a purchase agreement has to accommodate, so read it before you sign either document.

To be introduced, a shop needs 50+ full-time employees at peak (contractors excluded), several years of documented operations, rights to license the records and an authorized sponsor, such as the owner or CEO. A shop below that size can still be sold well but would not meet this baseline.

If you have a pending letter of intent, tell your advisor first. An exclusive license might be seen as an encumbrance on an asset the buyer expects to receive, so the sequence and wording should be agreed with counsel.

What to say to your advisor

When to skip it

• Fewer than 50 full-time employees at peak.
• Most records are customer-owned files with no consent.
• Work is controlled under export or defense rules and nobody has cleared a license.
• Nobody can export the ERP or quote history.

Our guides on selling a translation company and a freight forwarding company show how owners in other trades handle the same records question. The IT handover checklist covers system access, and the company fit checker gives a preliminary, non-binding screen. The full baseline is on who qualifies.
