I still remember the first time I sold a business. Well, “business” is a generous word. It was more like a side hustle with delusions of grandeur and a shoebox full of receipts. The buyer’s accountant took one look at my “records” and laughed. Not a polite chuckle either. A full belly laugh. I learned something that day: your financial house needs to be in order long before anyone shows up with a checkbook.
These days I’ve been on both sides of the table, and let me tell you, buyers are nosy. Not in a creepy way. In a “show me every penny since 2019” kind of way. Here’s what they actually dig into during diligence, and how to get your books ready before the spotlight hits.
They Want Clean Books, Not Perfect Ones
Nobody expects a small business to have pristine, audit-ready financials. What buyers hate is messy books. There’s a difference. Missing invoices and mystery expenses? Red flags. A QuickBooks file that reconciles every month, even with a few handwritten notes in the margins? Totally fine.
Here’s what to tidy up first:
-
Reconcile every bank and credit card account monthly. All of them. Yes, even the one you use for “business lunches” that are really just you and your dog.
-
Match every expense to a receipt or invoice. If you can’t find one, document why.
-
Separate personal and business spending. This one hurts, I know. But commingled funds make buyers run for the hills.
Revenue Recognition: The Silent Deal Killer
Buyers don’t just want to see money coming in. They want to see it coming in predictably. If your revenue spikes every March because of one whale client, say so. Hiding lumpy revenue is worse than having it.
Be ready to explain:
-
Your top five customers and what percentage of revenue each represents
-
Any contracts with auto-renewal or cancellation clauses
-
Seasonal patterns and how you plan around them
I once watched a deal nearly collapse because the seller “forgot” that 40 percent of revenue came from a single client. The buyer found out. They always find out.
Tax Filings and the Dreaded Notice Letter
Buyers pull tax transcripts. Every return, every schedule, every amendment. If you’ve got an open IRS notice sitting in a drawer, deal with it now. Not next quarter. Now.
A few things to have ready:
-
Filed returns for the last three to five years
-
Proof of payment for any payroll taxes
-
Documentation for any penalties or late fees you’ve paid
Old tax problems don’t necessarily kill a sale, but surprises do. Disclose early and you keep the trust.
The Paper Trail Buyers Trust Most
Here’s the thing about diligence. It’s not really about numbers. It’s about confidence. Buyers want to feel like nothing will jump out of the closet after closing. Clean records build that confidence. Messy ones erode it, no matter how profitable you are.
So before you list your business, do a dry run. Pretend you’re the buyer. Ask yourself the uncomfortable questions. Then fix what you find. Your future self, and your buyer’s accountant, will thank you.
