Here is a transaction I have watched happen more than once, in different industries, with different buyers, always the same way.
An owner sells his business. Sometime in the year of the sale, the company pays out a large one-time expense. A retention bonus to a key employee. A legal settlement. A transaction bonus. A roof.
Everyone in the room knows it will never happen again. The owner knows. The CPA knows. It gets mentioned on a call.
It doesn’t make the add-back schedule with documentation attached. The buyer’s quality-of-earnings provider tests the schedule, finds the item unsupported, and leaves it in earnings. Adjusted EBITDA comes down by $250,000.
At a five times multiple, the purchase price comes down by $1.25 million.
The owner is not being cheated. The buyer is not being unreasonable. The number simply moved, because nobody did four hours of work eighteen months earlier.
Why one dollar of earnings costs five dollars of price
Businesses in the lower middle market sell on a multiple of adjusted earnings. Whatever multiple your industry supports, every dollar that stays inside earnings is multiplied, and every dollar that comes out is multiplied too.
That arithmetic is obvious when you say it out loud. It is almost never applied when an owner is deciding whether it’s worth the trouble to pull the invoice.
It’s worth the trouble. On a five times multiple, an hour spent substantiating a $50,000 add-back is an hour that pays $250,000. There is no other work available to a business owner with that return.
What an add-back actually is
An add-back is an expense that runs through the business but doesn’t reflect what the business will cost to operate under a new owner.
The usual categories, roughly in order of how often they appear:
Owner compensation above market. If you pay yourself $400,000 and the job would pay a hired manager $180,000, the difference is an add-back. So is the compensation of a family member on payroll who doesn’t work there.
Personal expenses run through the company. Vehicles, travel, meals, phones, the boat. Every closely held business has some. Buyers expect it and won’t be shocked.
Related-party rent above or below market. If you own the building through a separate entity and charge the business $12,000 a month for space that would lease for $7,000, the difference is an add-back. If you charge $4,000, that’s a subtraction, and buyers find those too.
One-time expenses. The legal settlement, the failed product line, the flood, the consultant you hired once. This is the category with the highest failure rate, because the phrase “one-time” is doing a lot of work and requires proof.
Discontinued operations. A division you closed, a product you stopped making, a location you shut. The expenses go away with the revenue, and both have to come out.
The difference between claiming and documenting
An add-back schedule is a list of assertions. Every line is a claim about money, and a buyer’s provider treats it the way an auditor treats a claim: as unproven until it’s tied to something.
Tied to something means the general ledger transaction. Not a summary line on a P&L. Not a note in a spreadsheet that says “one-time legal.” The specific entries, with the invoice, the check, the payroll record, or the contract behind them.
Here’s what that means in practice. If you’re adding back $85,000 of legal expense from the year you were sued, you need the ledger entries totaling $85,000, the firm’s invoices, and enough context to show the matter is resolved and won’t recur. If you’re adding back a family member’s salary, you need the payroll records and an honest description of what they did or didn’t do.
If you’re adding back excess owner compensation, you need a defensible view of what the role pays in your market. That one is judgment rather than documentation, which means it’s negotiable, which means the seller who arrives with a compensation study and the seller who arrives with an opinion get different outcomes.
Undocumented add-backs don’t just get removed. They cost you credibility on the ones that are legitimate. A provider who disallows three items starts testing the other twelve differently. That’s the real damage: a schedule that looks aggressive turns a diligence process into an audit.
The transaction bonus problem
There’s one item that deserves its own warning, because it’s the most common and the most expensive.
Many owners pay a transaction bonus at closing. A key employee who stayed through the process, a long-tenured operations manager, sometimes an advisor. It’s the right thing to do and it’s entirely ordinary.
It is also a compensation expense on the company’s books, in the year of the sale, and if it doesn’t appear on the add-back schedule as non-recurring, the buyer capitalizes it.
A $250,000 transaction bonus that misses the schedule costs $1.25 million of purchase price at a five times multiple. The owner pays the bonus and then pays for it again, five times over, out of proceeds.
Flag it before the book goes out. Not during diligence, when it looks like you’re adjusting the numbers because the buyer pushed.
When this work has to happen
Before the business goes to market. Every time.
The reason is not that the work is different later. It’s that your position is. When your financial book goes out with a schedule already traced to transactions, the add-backs are a fact the buyer is underwriting. When you produce them in week seven of diligence, they’re a request, made by a seller who wants the price to be higher, to a buyer who has already committed capital to the process and knows you have a deadline.
Same evidence. Different negotiation.
There’s also a timing problem people miss. Documentation gets harder to assemble the further you are from the event. The firm that handled the litigation still has the file today. The bookkeeper who coded the entries still works there today. Two years from now you’ll be reconstructing.
What to do this quarter
If you’re twelve to twenty-four months from a sale, three things are worth doing now.
Pull the last three years of general ledger detail and go through it line by line for anything that isn’t a real operating cost of the business under a new owner. Not the P&L. The ledger.
For every item you find, put the supporting document in a folder named for the item. Not a note describing where the document is. The document.
Get a defensible market compensation figure for your own role, from a source you didn’t write.
That’s a few days of work, most of which your bookkeeper can do. Against a multiple, it is the highest-return few days available to you.
The uncomfortable part
Most owners hear this and assume it’s an argument for hiring someone. It is, partly. It’s also an argument for doing something you can do without hiring anyone, which is to stop treating your books as a tax document and start treating them as the thing a buyer will read.
Those are different jobs. For twenty years, the objective was to show as little profit as the law allows. Starting about two years before you sell, the objective inverts. Every dollar you legitimately spent that a new owner won’t have to spend is a dollar you have to be able to prove.
Nobody tells owners that the switch has to happen, or when. So it happens too late, in diligence, at the worst possible moment, for less money.
