Which Add-Backs Actually Survive Diligence

Add-backs are where most of the value in a small business deal actually moves. The revenue is usually the revenue. The argument is almost always about which expenses a buyer should ignore.

Very little of what we adjust is deliberate. It is presentation. The same economic fact, written up two different ways, either survives diligence or does not.

The presentation change that fixes most of it

The most common issue we see in CIMs is a market adjustment shown as a single net line.

Officer compensation is a good example. The owner takes $250,000. Market for the role is $110,000. The CIM shows one line: Officer compensation adjustment, $140,000. On paper it gets you to post-acquisition expense quickly, and it looks clean.

It collapses under diligence, because there is nothing to tie it to. Payroll records show $250,000. The tax return shows $250,000. The P&L shows $250,000. Nothing anywhere shows $140,000, so the reviewer has to reverse-engineer the assumption before they can test it, and any period where the owner's pay changed breaks the number silently.

The cleaner approach is two lines:

• Add back the actual historical expense, $250,000, which ties directly to payroll, the return, and the P&L.
• Layer in the assumed post-close expense, $110,000, as its own explicit line.

Same net result. Completely different durability. The historical figure is verifiable, the assumption is visible and can be argued on its own terms, and if the owner's pay moved between periods the model stays correct.

The same logic applies to related-party rent. Add back the rent actually paid to the owner's entity, then layer in market rent as a separate assumption. We see a meaningful number of adjustments in our reports that exist only because of how the CIM combined these two steps.

Add-backs that generally hold up

• Owner compensation above or below market, presented as gross-up and layer-in, supported by payroll records.
• Related-party rent at other than market, with a market rate you can point to.
• Documented personal expenses run through the business: the family vehicle, personal travel, a phone plan, a country club membership. Documented means we can see the transactions, not that the owner described them.
• Family members on payroll who do not work in the business. Common, legitimate to adjust, easy to support.
• Genuinely one-time costs with a paper trail: a legal settlement, a one-off relocation, storm damage. The test is whether a buyer would face the cost again.
• Non-cash items, depreciation and amortization, when you are working toward SDE or EBITDA.

Add-backs that usually do not

• Owner salary added back in full with no replacement. Unless the buyer is genuinely going to run the business themselves and take nothing, someone has to do the job and be paid for it.
• Deferred maintenance dressed as one-time. If the roof was patched this year and the fleet is due next year, that is a capital need, not an adjustment.
• One-time costs that recur. A legal settlement in each of the last three years is not one-time. It is a cost of doing business in that industry.
• Undocumented cash. Cash revenue that is not deposited cannot be verified, and it also cannot be financed. Lenders do not underwrite what is not in the bank.
• Marketing or software described as discretionary. Sometimes true. Usually the spend is holding up the revenue you are buying.
• Cash-basis timing presented as margin improvement. More on this below.

The one that costs buyers the most

Cash-basis timing is the quiet one, because nothing in it looks like an add-back at all.

Most small businesses keep their books on a cash basis, and banks underwrite off cash-basis financials, so a QoE usually starts there. That is all reasonable. The problem is that cash-basis results can move for reasons that have nothing to do with operating performance.

The clearest version is inventory. A distributor that is deliberately running down stock will show improving gross margin on a cash basis, because it is selling goods it paid for in an earlier period. Sales can be falling while margins climb. The pattern looks like a business getting more efficient. It is a business liquidating its balance sheet, and the buyer inherits the need to restock.

Deferred revenue does the same thing in the other direction, and so does a change in payment terms with a large customer.

How to present them if you are selling

Sellers sometimes read all of this as adversarial. It is the opposite. Clean add-backs get a higher price, because a buyer will not pay full value for a number they cannot verify.

Three things make the difference:

• Show actual historical expense and post-close assumption as separate lines, every time.
• Keep support for anything you are adjusting. A note in a spreadsheet is not support. An invoice is.
• Be consistent across periods. Adjustments that appear in one year and not another get treated as unreliable across the board, including the ones that were fine.

The add-backs that survive are not the aggressive ones or the conservative ones. They are the ones somebody can check.
