Buying or Selling a Fabrication Shop: The Complete Guide

Buying or selling a fabrication shop comes down to a weld, a cut, or a fit-up a lead can still sign, a backlog that is a purchase order rather than a quote on the wall, and equipment a buyer can insure. What trades is transferable cash flow after a real lead wage, more than one customer who will take a new name, and a quality file that does not live in your hood. A job shop, a production cell, and a contractor who fabricates only for his own jobs are different companies.

The short answer: a founder-run fab shop, where you still quote, fit, and walk the floor, is usually an SDE file and often trades around 2x–3.5x Seller's Discretionary Earnings after a real lead wage. A shop with a lead already on the clock, a second customer, and machines that are not one tired press can move toward 2.5x–4.5x SDE, and a managed floor can be read on adjusted EBITDA. Those ranges are directional. They are not a quote. A larger plant a sponsor might read as a platform or an add-on is a different file, covered in selling a manufacturing company to a PE platform versus an add-on and in the light manufacturing guide.

This guide is for fabrication shops — structural, sheet, misc metals, and short-run weldments whose engine is a bay, a fixture, and a customer who reorders or rebids. It is not a machine shop that only cuts chips, and it is not a contractor with a welder in the corner unless that welder is the business.

Shops that sell well have travelers that match invoices, a lead who has already run a Tuesday, a maintenance log, and customers with a name on the order. Shops that sell poorly are a founder who is still the only certified welder, one contractor at a third of sales, and a “backlog” that is a stack of unpaid bids.

This article is not legal, code, environmental, or insurance advice. Welding procedure qualifications, coatings, and scrap rules change by state and by customer. Confirm them with qualified counsel before you sign a letter of intent.

Why a Fabrication Shop Is Different

A fab shop sells a part that has to fit, a process, and a promise the next piece will match the last one. Several facts change the price:

• The procedure, not your eye, is the product. A shop that only holds a weld because you still strike the arc is key-person risk. A transferable shop runs on a WPS someone else can follow, a lead, and a check someone else can sign.
• Backlog is not a bid board. Signed orders and releases are backlog. “We usually get that job” is pipeline. Buyers haircut pipeline hard.
• One GC or one OEM reprices the file. Name the top customers and whether the work is a blanket or a handshake.
• Equipment age is a second price. A press brake, a laser, or a positioner with a lien and no log is not replacement cost.
• Certifications travel with people. AWS, ASME, or a customer’s approved-vendor list may be your name. A buyer who cannot be approved does not have the book yet.

Structural and misc metals sell to contractors and a schedule. Production fab sells a repeat part. Repair and field weld sells a truck and a person. Split them if they share a building but not a margin.

What Buyers Underwrite on the Floor

Backlog and takeoff

Backlog and takeoff are releases against an order, with material already priced. A busy whiteboard of bids is not in the price. Buyers want ship dates and whether the job still makes money if scrap is honest.

Customer concentration

Customer concentration is the first walk-away on a small shop. One general contractor, one OEM, or one agricultural account at a quarter of sales is that relationship. Get the top five, the contract or the handshake, and the last price increase on one page.

Machines and fixtures

Machines and fixtures are the brake, the laser, the welders, and the fixtures that make a repeat part fast. Fixtures you built for one customer may have no value if that customer leaves. Liens and the spare part matter more than a clean photo.

The lead and the tickets

The lead and the tickets are whether someone besides you can open, fit, and sign. If the certified welders are only you, the wage for that role comes out before a multiple. A shop with no second name on the quality sheet is a job with machines.

Repeat Parts Versus a Busy Bid Month

Buyers pay for releases that repeat. They haircut a one-time prototype, a storm of contractor work, and a customer who only orders when you call.

Blanket and repeat weldments with a traveler that matches the invoice are the book. Bid structural work is real and a weaker multiple. It depends on you winning the next job. Material and scrap have to sit in the gross margin. A shop that expenses steel in a lump will lose that margin in diligence.

What a buyer will pay for is the test in recurring revenue a buyer will fund: a file they can reconcile, a customer who is not only you, and a process that survives a new name. A Sun Belt contractor shop and a Midwest production cell differ in season and wage. They do not differ in the four items: backlog, concentration, machines, and a lead.

How Buyers Value a Fabrication Shop

Start with a real valuation.

Seller's discretionary earnings

Seller's discretionary earnings still clears most founder-run shops. Owner pay and true one-offs come back. A market wage for quoting, fitting, and the hours you still weld does not.

Adjusted EBITDA

Adjusted EBITDA is for a floor that already opens with a lead and already invoices more than one customer. Concentration and machine condition move the multiple. They do not turn a one-customer shop into a platform.

Who Buys, and How the Check Gets Written

Owner-operators buy a bay so they can stop quoting from zero. They can weld. They still need a wage that assumes they are not you, and a customer approval they can hold.

Contractors and adjacent plants buy capacity they already send out. They underwrite whether your lead will stay.

A small group or a sponsor shows up when there is a lead, a second customer, and a file. Most fab shops are Main Street until that lead exists. Larger files belong in who a $5–$50 million company needs.

SBA 7(a) can fund a smaller shop when a lead can run the floor and equipment liens are mapped. The 7(a) cap is $5 million. SBA 504 can finance real estate and long-lived machines. It is not a loan for the goodwill of a customer list.

Lenders read the file the way we describe in working with an SBA lender: travelers that match invoices, a lease they can live with, and a use of proceeds that includes material and any machine note. One customer is the usual haircut.

Seller financing is common when you are still the estimator or the only ticketed welder. Earn-outs show up when the backlog is verbal. An earn-out that only pays if you keep quoting is not a clean exit.

Diligence and the Year Before You List

Keep the floor from hearing about the file before you are ready. The same rules are in how to sell your company confidentially. Prepare with our due diligence guide and the 12–36 month roadmap.

Use the year. Write signed backlog apart from bids. Name the top customers. Log the machines and the tickets. Put a lead on a wage that is in the books. Quote-board annualization, one contractor, a brake with no log, and a public listing that spooks that contractor quietly reprice the deal.

What a Buyer Will Ask on the First Call

A buyer of a fab shop asks who can weld and sign if you are not there, which orders are released rather than hoped for, which machine is one breakdown away from stopping the week, and which customer can take the book with them. Those four answers decide whether the file is a company or a skilled job with equipment.

Put the tickets on the table. If a customer approval or an AWS ticket is your name, the letter of intent needs a date by which a second person is qualified or the customer has accepted the buyer. A shop that loses the approved-vendor list at closing is a different company from the one in the photos. Say that early. It is cheaper than discovering it after a lender has ordered an appraisal of the brake.

Material is the other quiet cut. Steel bought for a job that was never released, drops you cannot use, and a coating subcontract you have been burying in “outside services” all change gross margin. A buyer will tie invoices to travelers. If the travelers do not exist, they will haircut the margin until they do. Build the traveler for the jobs you still have, not for a sample you wish you had run.

A Florida structural shop and an Ohio production cell can both sell. The wage, the power bill, and the customer’s industry change. The test does not: a lead, a second customer, a machine log, and a backlog that is paper. A quote on the wall is how owners talk themselves into a higher multiple. It is also how that multiple comes back off in week three of diligence.

Read the first offer as a ceiling until the equipment schedule is real. If the brake, the laser, and the forklift are “to be confirmed,” the number is not a price yet. Ask which jobs in the backlog are included and which deposits stay with you. A buyer who wants the work and also wants the cash already collected is asking you to finance the jobs. That can be fair when the note is priced for it. It is not fair when the letter is silent. The same letter should say who keeps warranty on work you already shipped. A cracked weld from last spring should not become your problem in July because nobody wrote the sentence down. Put the answer in the letter of intent, not in a side email you will not find at closing. Bring the machine hours with that letter so the appraisal is not the first time anyone sees them.
