Normalize seller financials and document every adjustment.

How to analyze a small business acquisition.
A small business acquisition should be screened with normalized income, realistic expenses, financing assumptions, tax effects, owner dependency, working capital needs, and buyer return thresholds before deeper diligence begins.
Start with normalized numbers
Separate seller claims from verified income and expenses. Review tax returns, profit and loss statements, bank records, payroll, merchant statements, debt schedules, rent obligations, and recurring add-backs before relying on seller-provided earnings.
Normalize owner compensation, one-time expenses, related-party expenses, under-market rent, missing payroll, deferred maintenance, software subscriptions, insurance, and replacement labor. The goal is to estimate what the business can produce for a buyer using buyer-relevant assumptions.
Identify business-specific risks
Small business acquisitions can depend heavily on the seller, a few customers, a key employee, a location, a supplier relationship, licenses, or informal processes. Those risks can change the value of the cash flow even when the headline profit looks attractive.
Customer concentration, seasonality, weak records, declining revenue quality, high employee turnover, pending lease changes, and owner-managed sales pipelines should be flagged before spending heavily on diligence.
Add financing and buyer cash flow
After normalizing income and expenses, add financing assumptions. Debt service, down payment, lender fees, working capital, closing costs, and transition reserves affect DSCR, cash-on-cash return, payback context, and estimated monthly cash flow.
The buyer should also account for personal income needs or manager replacement cost. A business can appear profitable but still leave too little cash after debt service, taxes, reinvestment, and operating cushion.
Screen before diligence
Review NOI or seller discretionary earnings with clear assumptions.
Add financing terms, cash invested, estimated taxes, and required reserves.
Review DSCR, cash-on-cash return, NIAT, payback context, income cushion, and warning signals.
Decide whether the opportunity deserves deeper legal, accounting, tax, operational, and financing review.
Signals to pause or dig deeper
Pause when records are incomplete, add-backs are unsupported, the seller is central to revenue, customer concentration is high, lease terms are uncertain, or financing assumptions only work with optimistic income.
These signals tell the buyer what must be verified before moving from first-pass review to diligence.
