What Is Your Shop Actually Worth? What a Buyer Does to Your Number First
The multiple gets most of the attention when an owner thinks about selling. The earnings underneath it deserve the first look. A buyer will rebuild that number on their terms before price negotiations get very far.
The rebuild usually has three parts. The buyer prices the cost of replacing the owner, tests the support behind every add-back, and evaluates how well the shop's earnings transfer after the owner leaves.
Start with the number in your head
When an owner tells me what the shop makes, they're often quoting seller's discretionary earnings. SDE starts with net profit and adds back owner compensation, owner benefits, and expenses that shouldn't continue under a buyer. For a single shop, it's a fair and normal starting point.

A buyer still needs an earnings number that reflects the business running under new ownership. That's where the rebuild begins.
Move one: price the cost of replacing the owner
A buyer has to run the shop after the owner leaves. If a general manager who can carry that responsibility costs $130,000 a year, the buyer subtracts that amount from SDE.
This line can move the earnings base more than a partial turn in the multiple would move the final price. Owners feel the adjustment because the work was already getting done. The buyer sees the future cost of keeping it done.
Move two: support the add-backs
Every add-back needs a clear reason and documentation. A one-time legal bill may hold up. A recurring repair labeled as unusual may not. Personal use inside a business expense may need to be separated. Whatever lacks support goes back into the cost base.
Seller math and buyer math often separate here. A disciplined buyer gives credit for adjustments they can verify.
Move three: evaluate transferability
A shop's earnings carry more risk when the owner still holds the estimating judgment, insurer relationships, referral sources, or team leadership together personally. A buyer can reflect that risk in the multiple, an earn-out, a seller note, or another holdback tied to the transition.
Transferability asks a practical question. How much of today's performance will still be there after the owner leaves?
The worked example
Start with $500,000 of SDE.
Subtract a $130,000 market manager salary. The earnings base moves to $370,000.
Assume the owner claimed $80,000 of add-backs. Documentation supports $50,000, so $30,000 returns to costs. The earnings base moves to $340,000.
At a four-times multiple, $500,000 produces a headline value of $2,000,000. The rebuilt $340,000 produces $1,360,000. The $640,000 gap came from the earnings work before anyone changed the multiple.
These numbers are illustrative. Your shop will have its own manager cost, add-backs, risk profile, and deal terms.
What the multiple actually multiplies
The multiple matters. It gets applied after the buyer has rebuilt the earnings base. In this example, a half-turn on $340,000 is worth $170,000. The earnings rebuild moved the value by $640,000.
That comparison helps put the negotiation in order. Understand the earnings base first, then evaluate the multiple applied to it.
Quality of earnings, in one line
A formal quality-of-earnings review restates earnings on the buyer's terms and tests whether they are real, recurring, and transferable. Running these three moves early gives an owner a useful preview before paying for a formal process.
Time changes what you can fix
Five or more years before a possible sale, an owner has time to reduce dependency, build management depth, create cleaner reporting, and establish a track record that a buyer can verify.
Two to three years out, the focus shifts toward proof. Can the team run the shop through the owner's absence? Do the add-backs hold up across multiple periods? Are customer, insurer, and referral concentrations visible in the numbers?
Inside one year, the range of fixes narrows. Documentation can improve and expectations can become more realistic. Deep transferability usually needs operating history, which takes time to create.
A higher multiple can still produce a weaker deal
The headline multiple is one line in the transaction. Cash at close, an earn-out, rollover equity, seller financing, working capital adjustments, and the conditions attached to each dollar determine what the owner actually receives and when.
A higher multiple with a large conditional earn-out may carry more risk than a lower all-cash offer. Owners should compare the full structure and the probability of collecting each piece, not only the number quoted at the top.
What the rebuilt earnings number leaves out
Real estate, equipment, location value, certifications, and a strategic buyer's specific reason to pay more can affect the final deal. Those items enter after the core earnings are understood.
Run the buyer's math early
If selling is anywhere on your horizon, start with the manager-salary line. Then pressure-test the add-backs and look honestly at how much of the business depends on the owner being present.
Most owners would rather learn the answer while they still have years to improve it. The work also pays before a sale. A shop that depends less on the owner can become easier to own right now.

Should You Drop Your DRP? Run This Number First
The DRP keep-or-drop decision comes down to one break-even retention number. Here is the full model, in dollars, with the adjustments most versions of this argument skip.
Why a collision group keeps paying rent on a shop it closed.
A group closes a shop and keeps paying rent on the empty building for years. It looks like a mistake. Usually it's a hard call someone already ran the numbers on, and the math behind it is worth understanding for your own shop.
The Fatal Assumption that's closing collision shops
Volume is down and owners are asking whether they need to get back on the tools. Michael Gerber named the trap in that question decades ago. Here's the skill that actually saves a shop.
