Selling a manufacturing business: what changes your price

From Matt Behrens, who has bought businesses for 15 years · 2026-10-02

If you own a small manufacturing company, you know how much of it lives in your machines, your people and your customers' trust. You may also know how little of that is written down. Buyers of manufacturers look hard at those three things, and at what it would cost to keep the plant running after you step back.

The situations that change your price in manufacturing

Customer concentration

Many small manufacturers grew by doing excellent work for one or two large customers. That is a strength, and it is also a risk. If one customer is a big part of your sales, a buyer asks what happens if that customer changes suppliers, moves production or simply renegotiates. The answer affects both price and whether a lender will fund the deal.

Buyers will ask how long each top customer has been with you, whether there are contracts or purchase agreements, and how the customer would react to a new owner. You cannot fix concentration in a month, but you can start now: quote new customers, widen the products you sell, and keep your best accounts close and happy.

Equipment age and what it will cost to keep running

A buyer will walk the floor and look at your machines. Old equipment is not automatically bad, since a well-kept machine can run for decades. What buyers want to know is what needs replacing soon, what you have been putting off, and what a normal year of capital spending looks like.

If you have deferred maintenance, expect the buyer to price it in. Keep maintenance logs, list each major machine with its age and condition, and be honest about what needs work. A buyer who discovers a problem on their own lowers the price and trusts you less. A buyer who hears it from you can plan for it.

The people who know how to make the product

Skilled machinists, welders, programmers and quality people are hard to find and harder to replace. If a few of them carry knowledge that is not written down, a buyer sees a risk. If your setups, programs and methods live in someone's head, they walk out the door with that person.

Matt's experience: I once evaluated an HVAC equipment manufacturer with $30 million of revenue that was highly profitable. On paper everything looked great. But when I walked the floor with the owner, it was a mess: raw materials and half-finished inventory stashed everywhere. The owner knew exactly where everything was, what stage each piece was in, and when each customer expected shipment. It worked well for him, and he thought things were great. I knew immediately that if he left for a week, things would fall apart. To buy the business I would have had to hire a replacement for the owner and spend the time and money to build the processes, procedures and redundancy that a business that size needs.

Write down procedures, save the machine programs and fixtures in a place the company controls, and train a second person on the critical jobs. Talk with your key people about their future in the company, and ask a professional how to keep them through a transition.

Inventory, cost accounting and the rest of the plant

Buyers want to be sure your reported profit is real. That depends on how you value inventory, how you track the cost of each product, and whether your quoted prices cover the true cost of making it. Old or slow-moving inventory may be worth less than it is carried for. Quality certifications, if your customers require them, need to be current and transferable. And if you own the building, a buyer will ask whether it is part of the sale or leased to the new owner. Finally, know which suppliers you cannot easily replace, since a single source for a key material is a risk buyers ask about.

What a buyer and a lender will ask

• Sales by customer for three years, with the top customers identified.
• Any contracts, purchase agreements and how long the relationships have lasted.
• A list of equipment with age, condition, maintenance records and any loans.
• Recent and expected capital spending.
• How inventory is counted and valued, and what is old or slow.
• How product costs are calculated and how quotes are built.
• Required certifications and audit history.
• Key employees, their roles and any written agreements.
• Who supplies your critical materials, and what the alternatives are.
• Who owns the building, and what lease terms would apply after a sale.

What to fix 12 to 24 months out

1. Work on your customer mix: pursue new accounts and track how much depends on your largest.
2. Keep a log of every major machine, its age, its condition and its maintenance history.
3. Catch up on deferred repairs you know about, or at least document them and their likely cost.
4. Document the critical processes, and train a second person on each one.
5. Clean up cost accounting so you know what each product really costs to make.
6. Count inventory regularly and deal with the old stock.
7. Line up a second source for any key material that has only one supplier.
8. Decide, with a professional, how you want to handle the real estate.

Common questions

Will a buyer pay for my equipment separately?

Sometimes, but usually equipment is part of the value of the business as a whole. If the equipment is required to run the business you are selling, buyers will require it as part of the sale.

What if my biggest customer is most of my sales?

It will affect how buyers see the risk, and you should plan for that. Longer agreements, a good relationship and steady progress on adding new customers all help. Remember, buyers pay more for a business when they are confident about future earnings, and pay less or walk away when there is risk or uncertainty about future profits.

Do I need to keep my certifications up to date while I sell?

Yes. Lapsed certifications can stop work and worry buyers. Check the rules that apply to you with a professional.
