Buying a Business? Read the Books First
A seller's financials are a story, told by the one person with every incentive to make it sound good. Your job, before you wire the money, is to work out how much of that story is true — because you pay the multiple on every dollar you take at face value.
The add-back game, from the buyer's seat
By the time a business reaches you, its earnings have usually been adjusted — the owner's salary normalized, personal expenses stripped out, a pile of costs relabeled as "one-time." Some of those adjustments are legitimate. Some are hopeful. And because you're paying a multiple of that adjusted number, the soft ones are expensive in a way that catches first-time buyers off guard.
You aren't negotiating a dollar when you challenge an add-back. You're negotiating the multiple times that dollar. Which means an afternoon spent disproving a questionable adjustment can be the highest-paid work in the entire deal.
Quality of earnings: your side of the table
A quality-of-earnings analysis is the buyer's tool for turning a seller's story into a verified number. It tests whether the revenue is real and repeatable, whether the add-backs hold up, how much of the profit depends on one customer or one owner, and whether working capital has been managed honestly.
It is, bluntly, the cheapest insurance in the deal. At a five or six multiple, the cost of a proper earnings review is a rounding error against the money you'd overpay by trusting a number that turns out to be soft.
Red flags that hide in a clean-looking P&L
A tidy profit-and-loss statement can still be hiding the things that matter most. Revenue recognized too early or too aggressively. A single customer quietly responsible for a third of sales. A business that runs entirely on the departing owner's relationships. Working capital starved to flatter cash. Deferred maintenance and under-investment dressed up as strong margins. One good year presented as the new normal.
None of these show up as a line labeled "problem." They show up as questions the books can't answer cleanly — which is exactly why you read the books, and read them skeptically, before you sign anything binding.
Clean books after close matter too
Diligence tells you what you're buying. Clean books from day one tell you whether you can run it. Plenty of acquisitions are won in diligence and then lost in the first year because the new owner inherited a reporting black box and couldn't see a problem until it was a crisis.
Standing up real finance — reconciled books, a monthly close, reporting you can actually steer by — in the first ninety days is how you turn a good purchase into a business you control instead of one that surprises you.
Before you sign the LOI
The best time to get a clear-eyed read on a target's numbers is before you're emotionally committed and contractually anchored. Get the earnings verified, get the red flags surfaced, and know exactly what you're paying the multiple for — while you still have the leverage to walk or renegotiate.
Straight answers
What's buy-side quality of earnings?
It's an independent analysis of a target's earnings on your behalf — verifying that the profit is real and repeatable, that the add-backs hold up, and that nothing structural (customer concentration, owner-dependence, working-capital games) is hiding under a clean-looking P&L. It protects the price you pay.
I'm a self-funded searcher, not a fund. Is this overkill?
It's arguably more important — a fund can absorb a mistake across a portfolio; you can't. You don't need a giant firm's process, but you do need the earnings verified and the red flags surfaced before you commit your capital and your next several years.
How much diligence is enough?
Enough to answer three questions with evidence: is the profit real, is it repeatable without the current owner, and what am I actually paying the multiple for. If the books can't support clean answers, that's not a paperwork problem — it's information about the deal.
The seller's books are a mess. Walk away?
Not necessarily — sometimes messy books hide an underpriced gem, and a buyer willing to do the work can win there. But messy books mean you price in the uncertainty and verify more, not less. The discount should be yours, not the seller's.
