The #1 Valuation Mistake That's Costing You at Sale: Messy SDE Add-Backs#
It's not your revenue. It's not your margins. It's not even your industry. The thing quietly shaving hundreds of thousands off your sale price is how you've been treating your own financials, specifically, your SDE add-backs.
Why This Mistake Is So Easy to Make#
Most owners run their business, in part, through the business. A personal vehicle lease. A spouse on payroll who doesn't really work the job. A one-off legal fight last year that ate into profit. None of that is wrong, it's just normal small-business life. The problem is what happens when a buyer's team sits down with your P&L and can't tell the difference between how this business runs and how you personally run your life.

Under-adding: leaving real profit on the table#
You understate what the business actually earns. If you don't add back your above-market owner salary, one-time legal costs, or personal expenses run through the business, your P&L understates true cash flow, and valuation is a multiple of that number.
Buyers price off what's documented, not what you tell them. A verbal "oh, that expense wasn't really the business" doesn't move the multiple. If it's not on a clean schedule with support, it doesn't count.
Over-adding: the fastest way to blow up a deal#
Aggressive, unsupportable add-backs erode trust fast. The moment a buyer's diligence team catches one add-back that doesn't hold up, they start re-checking everything else you've claimed, including the legitimate ones.
It resets the negotiation, not just one line item. A buyer who feels misled on add-backs doesn't just adjust the number down. They start negotiating from a position of suspicion, which shows up in price, terms, and how much escrow they demand.
How to Fix It#
1. Calculate SDE properly, every time.
SDE = Net Profit + Owner's Salary + Owner's Benefits + Interest + Depreciation and Amortization + One-Time/Non-Recurring Expenses
Read it as: start from what the business reported, then add back everything that reflects your personal choices or one-off events rather than the ongoing cost of running the business.
2. Document every add-back like a buyer will challenge it, because they will. Keep receipts, invoices, and a plain-English explanation for each line. "Personal cell phone, $80 a month, 24 months" is defensible. "Misc adjustments, $40k" is not.
3. Separate recurring from one-time, and label them as such. An owner's-salary add-back is recurring and expected. A one-off lawsuit settlement is not, and buyers will accept it more readily precisely because you flagged it as non-recurring rather than folding it into "normal" earnings.
4. Get a second set of eyes before you go to market. What feels obviously legitimate to you as the owner often looks different to a CPA who's seen a hundred CIMs fall apart on this exact issue.
Openfair's CPA-backed valuation process exists specifically to catch this before a buyer does, cleaning up add-backs and normalizing your financials as part of building your CIM, so the number you bring to market is one that survives diligence instead of collapsing under it.
If you're not sure whether your add-backs would hold up, Openfair's free valuation tool is a good place to start finding out.
Frequently Asked Questions#
What counts as a legitimate SDE add-back? Anything that reflects your personal choices rather than the ongoing cost of operating the business: your salary above or below fair market rate, personal expenses run through the company, one-time non-operating costs, and non-cash items like depreciation.
Can I add back my own salary if I don't take one? Yes. If you work in the business without pay, a buyer needs to know what it would cost to replace you, so an imputed market-rate salary is typically added back (or effectively subtracted, if you're underpaid relative to the role).
How many add-backs is too many? There's no fixed number. The test isn't quantity, it's whether each one is documented and defensible. Ten well-supported add-backs are fine; two unsupported ones can sink the whole schedule's credibility.
Will buyers just take my add-back schedule at face value? No. Expect every material add-back to be tested in due diligence. Treat your schedule as something that needs to survive scrutiny, not just look good in a first pitch.
Does this only matter if I'm selling soon? No. Cleaning up add-backs 12 to 18 months before a sale gives you time to actually change behavior (e.g. moving personal expenses off the books) rather than just explaining it after the fact, which is a stronger position with buyers.
