A clean-looking P&L is one of the easiest things for a broker to produce. It's also one of the least informative documents in a data room on its own — what matters is whether the numbers on it actually reconcile with everything else the business has generated over the years. Here are five patterns worth checking for before you spend real time and money on a deal.
1. Net income that moves around between documents
Pull the P&L, the tax return, and any bank statements or quality-of-earnings summary for the same fiscal year. The bottom-line figure should either match exactly or reconcile with an explainable difference — book-to-tax adjustments, accrual timing. If the "same year's" net income is meaningfully different across documents with no explanation, that's not a rounding issue. It means at least one of those documents is wrong, outdated, or was prepared under different assumptions, and you don't yet know which one to trust.
2. Addbacks that dwarf reported profit
If GAAP net income is $150,000 and the "Adjusted SDE" after addbacks is $400,000, that ratio alone isn't disqualifying — but it does mean more than half of what you're being asked to pay for exists only in a spreadsheet, not in a tax return. Push for line-item support for every addback before anchoring any part of your valuation to the adjusted figure. See our addback checklist for what to ask for.
3. Revenue that's clean in aggregate, opaque underneath
A P&L shows total revenue by category — service, product, monitoring, whatever the business's segments are. What it doesn't show is customer concentration. A business with $2 million in revenue spread across 200 customers is a fundamentally different risk profile than one where three customers make up 60% of it, and you cannot tell the difference from the P&L alone.
Ask for: a customer-level revenue export, not just category totals.
4. Recurring revenue claims without a roll-forward
If a business advertises recurring or contract revenue as a core part of its value — a monitoring book, a subscription base, service contracts — the P&L will show you the current run-rate, but not whether that base is growing, shrinking, or churning underneath a flat headline number. A recurring revenue figure that's stable at the top level can still be losing 15% of accounts a year if new sales are backfilling the loss at the same rate.
Ask for: an account-level roll-forward covering at least 24 months — new accounts added, accounts lost, and net change by month — not just a single current total.
5. Generic account names carrying related-party activity
"Consulting Fees," "Management Expenses," "Professional Fees" — these are exactly the kind of catch-all account names that related-party payments hide inside. A $40,000 "consulting" line could be a legitimate outside vendor, or it could be a payment to the owner's spouse for work that will need to be replaced, or eliminated, after close.
Ask for: the general ledger detail behind any account name generic enough that you can't tell who's actually being paid.
None of these five patterns are automatic dealbreakers. Businesses are messy, and small companies in particular often have financials that reflect years of ad hoc bookkeeping decisions rather than any intent to mislead. The point of checking for them isn't suspicion for its own sake — it's making sure that by the time you're deep into diligence, you're spending that time on real questions about the business, not discovering the starting numbers were never right in the first place.
