Let me tell you about the phone call that nearly cost my client $400,000. He was three weeks from closing on a commercial cleaning company, feeling good, already mentally redecorating the office. Then his lender’s due diligence guy asked one question: “Can we see the proof behind those add-backs?” Crickets. The seller had claimed $300K in “owner expenses” running through the business. Problem was, half of it couldn’t be documented. Deal got repriced. Hard. So yeah, we’re talking about add-backs today, and you should probably pay attention.

What Are Add-Backs and Why Do They Matter So Much?

Quick refresher for anyone new to this game. When a business owner sells, the price is usually a multiple of earnings. Those earnings get “adjusted” because owners love running personal stuff through the company. The lease on the Porsche. The “business development” trip to Cabo. The family cell phone plan. Add those expenses back to profit and the earnings number jumps. Bigger number, bigger multiple, bigger check at closing.

Here’s the thing though. Buyers aren’t naive anymore. Every serious buyer, and especially anyone using an SBA loan or institutional financing, will run what I call an add-back audit before they agree to a price. They’re not being jerks. They’re protecting themselves. And honestly? If you’re a seller, you should welcome it. Clean add-backs survive scrutiny. Sketchy ones were never real money anyway.

How Buyers Actually Verify Owner Expenses

This isn’t some mysterious process. It’s grunt work, and it follows a pretty predictable playbook:

1. They pull the tax returns and financials side by side. Discrepancies between what was reported to the IRS and what’s on the P&L get flagged immediately.

2. They request bank statements and credit card statements. Not summaries. Full statements. Every line item.

3. They trace each add-back to a specific transaction. If the seller claims $60K in personal auto expenses, the buyer wants to see the payments, the insurance, the fuel receipts.

4. They check for double dipping. This one gets people. An owner takes a $150K salary AND claims add-backs for “owner compensation.” That’s not an add-back, that’s just his pay.

5. They look at personal expenses buried in COGS. Family members on payroll who don’t work there. Inventory that somehow ended up at the owner’s house.

6. They interview the bookkeeper or CPA. Sometimes both. You’d be shocked what a frustrated bookkeeper will confirm.

7. They compare add-backs against industry norms. If your add-backs are 40% of revenue and the industry average is 8%, expect questions. Lots of them.

The Red Flags That Kill Deals

I’ve sat through enough of these to know the patterns. Watch for these:

• Add-backs without documentation. If it can’t be traced to a statement or receipt, it’s a story, not an expense.

• “One-time” expenses that happen every year. The new roof that got replaced in 2021, 2022, and 2023? Not one-time.

• Vague categories like “miscellaneous owner expenses.” Buyers hate this. Lenders hate it more.

• Personal expenses mixed into operating costs. A gym membership coded as “employee wellness” is the kind of thing that makes a buyer walk.

• Resistance to providing records. The fastest way to lose trust is to act like the requests are unreasonable.

What Sellers Should Do Before Going to Market

Here’s my advice, and take it from someone who’s watched too many deals wobble at the finish line:

• Build a clean add-back schedule with a paper trail for every single line item

• Get your CPA to sign off on the adjustments before buyers ever see them

• Separate personal and business expenses going forward, starting today, not next quarter

• Keep a dedicated folder with statements, receipts, and explanations ready to hand over

• Price your business on the documented number, not the wishful one

The sellers who do this prep work close faster and hold their price. The ones who wing it end up renegotiating in the eleventh hour, and trust me, the buyer has all the leverage at that point. Nobody wants to be my cleaning company guy, three weeks from closing, watching $400K evaporate because he couldn’t find a receipt.

Do the audit yourself before someone else does it for you. Your future self will thank you.
