Due diligence
What to Look For
Practical guidance from hundreds of real acquisition conversations.
Customer Order Book
- Ask to see the customer list, how many active accounts the shop serves, and whether there are any long-term purchase orders with committed volumes.
- Shops where a significant portion of revenue comes from scheduled orders with customers who have committed for multiple years give you real visibility into what business looks like after you take over.
- Understanding whether any single customer represents a large concentration of revenue is equally important.
- Ask how long the top three customers have been ordering and whether any of those relationships are under contract.
Equipment Condition and Capacity
- Get a clear picture of the major equipment: what machines are in the shop, how old they are, and whether there's been consistent maintenance.
- A shop with well-maintained CNC machines, inspection equipment, and documented setup procedures is a very different starting point than one where key equipment is aging and deferred.
- Understanding current capacity utilization and where the ceiling is also tells you a lot about growth potential.
- Ask for a maintenance log on any major machine that represents a significant share of shop revenue.
Quality Certifications
- Certifications like AS9100, IATF 16949, or NADCAP take years and significant investment to earn and open doors with customers who require them.
- A shop that already has the relevant certifications in place is offering you something extremely expensive and time-consuming to build from scratch.
- Understand which certifications the business holds, which are company-held versus individually held, and how they transfer as part of the sale.
Skilled Workforce Stability
- The machinists, programmers, and quality technicians who understand the equipment and the customers are the core of the business.
- Ask how long the key people have been with the shop, whether setup documentation exists for major jobs, and whether institutional knowledge lives in written form or only in people's heads.
- Shops with tenured, documented teams transfer far more reliably than those dependent on one or two key individuals.
- Find out whether any key operators have indicated they plan to stay after a sale.
Revenue Concentration by Customer
- Understand what percentage of revenue comes from your top three or four customers.
- Shops with work spread across many accounts in different industries and end markets are more resilient to a single customer pulling back.
- If there is a large anchor customer, understanding the length of that relationship and whether there are long-term contracts is worth spending time on early.
