12 Profit and Loss Lines a Buyer Will Question

Short answer

The profit and loss lines a buyer will question are the ones that involve a judgment call rather than a bank transaction. Revenue timing, what sits inside cost of goods sold, how labor is split, owner compensation, related-party rent, and one-time costs buried in ordinary expense lines. A buyer is not looking for fraud. They are looking for lines where a different reasonable person would have booked it differently.

Every owner going into a sale expects the buyer to check the bottom line. What actually happens is slower and more specific. A diligence analyst reads the profit and loss statement from the top down, and at each line they ask one question: is this number a fact, or is it a decision somebody made? Facts get accepted. Decisions get asked about.

A normalized profit and loss statement is a version of your income statement restated so each line reflects what the business would earn under a new owner, with owner-specific and non-recurring items separated out rather than buried inside operating expenses. Building that statement is most of what the finance side of a sale actually consists of, and it goes quickly or slowly depending entirely on whether the underlying lines can be explained.

Below are the twelve lines that draw questions, in statement order, top to bottom. For each one, the question the buyer asks and what your books need to have ready.

The 12 lines, in statement order

1. Revenue, and the point at which you recognize it

Revenue recognition timing is the first thing a buyer tests, because it decides which period every other number belongs to. The question is straightforward: does revenue land when the invoice goes out, when the cash arrives, or when the work is delivered? For a business with deposits, progress billing, deferred maintenance plans, or annual contracts billed up front, those three answers can differ by months and can shift earnings between years. What your books need ready: a written statement of your recognition policy in one paragraph, applied consistently across the periods being shown, and a deferred revenue balance that reconciles to the underlying customer obligations.

2. Revenue segmentation, or the absence of it

A single undifferentiated revenue line invites the buyer to build their own segmentation, using their assumptions instead of yours. Buyers want revenue split by customer, by product or service line, and usually by recurring versus one-time, because those splits tell them which parts of the business they are actually buying and which parts carry risk. If your general ledger cannot produce that split, someone will build it by hand from invoices during diligence, slowly, and the version they build is the version that gets used. What your books need ready: revenue mapped to segments in the ledger itself, not in a spreadsheet someone maintains separately.

3. Discounts, refunds, and returns netted into one line

Netting discounts and returns against revenue hides a number a buyer specifically wants to see. Gross revenue less the deductions tells them how much of your top line is being given back, whether that is trending, and whether pricing discipline is holding. When the three are collapsed into one net figure, the buyer cannot see any of that, and the usual result is a request for the detail anyway, on a deadline. What your books need ready: gross revenue, discounts, and returns as separate accounts, with at least twenty-four months of history so the trend is visible.

4. Cost of goods sold, and what you decided to put in it

What belongs inside cost of goods sold is a genuine judgment call and varies by business, which is exactly why buyers ask. Two companies in the same trade can classify freight, warranty work, small tools, subcontractor costs, or vehicle expense differently and both be defensible. The problem is never the choice. It is inconsistency, either across periods or against how the industry generally reports, because both make your gross margin incomparable. What your books need ready: a written definition of what your cost of goods sold contains, and the same definition applied to every period in the file.

5. Direct labor split between cost of goods sold and overhead

The labor split is the single most common source of unexplained gross margin movement, and gross margin is the ratio buyers watch most closely. When a supervisor's time is partly billable and partly not, or when the same crew does production work in busy months and shop work in slow ones, the allocation between cost of goods and overhead is a decision made every payroll. If that decision changed at some point, or was never made consistently, your margin will move for reasons nobody in the company can explain to a stranger. What your books need ready: a documented allocation method, and an explanation for any period where the method changed.

6. Inventory adjustments that land in cost of goods sold at year end

A large year-end inventory adjustment tells a buyer that the number was not right during the year. Where inventory is counted once annually and the correction is booked in a single month, twelve months of gross margin are distorted, eleven of them one way and one of them the other. Buyers deal with this by discounting the monthly detail and looking only at annual figures, which costs you the ability to show a good recent trend. What your books need ready: a documented cycle count or periodic count process, and adjustments spread to the periods they belong to rather than dropped in December.

7. Owner compensation, and anything paid to family

Owner compensation is questioned in every deal, without exception, because the buyer is trying to work out what the role costs at market rather than what you chose to pay yourself. The same applies to family members on payroll, whether they work in the business full time, part time, or not at all. This is a documentation exercise, not an argument: the buyer wants to see who was paid, what they did, and what replacing them would cost. What your books need ready: a schedule of every family member and owner on payroll, their actual role and hours, and total compensation including benefits and vehicle costs.

8. Rent paid to an entity you also own

Rent paid to a related party gets flagged automatically, because the buyer cannot assume the rate is what an unrelated landlord would charge. Whether the rate is above or below market changes reported earnings in a way that has nothing to do with how the business performs, and the buyer will restate it either way. Whether the property transfers, stays, or gets leased back is a separate question that belongs with your own attorney and advisors. What your books need ready: the lease document, the related-party relationship stated plainly, and any third-party evidence you have about local rates for comparable space.

9. Professional fees in a year when something unusual happened

A spike in legal or accounting fees is a question about the event, not the expense. Buyers see an unusual professional fee balance and want to know what caused it, because the answer is sometimes a genuinely non-recurring project and sometimes a dispute, a claim, or a problem that has not been disclosed yet. Both answers are workable. Only one of them is workable if it comes out later rather than earlier. What your books need ready: professional fees broken out by matter or provider, with a one-line description of anything unusual and what it related to.

10. Marketing and discretionary spend that changes in the year before a sale

A visible drop in marketing, training, or repairs in the most recent year gets read as earnings management, whether it was or not. The buyer's assumption is that spending was suppressed to make the trailing twelve months look better, and their response is to add the normal level of spending back into their model. If the reduction had a real cause, such as a campaign that ended or a channel that stopped working, that is a good answer and it needs to be on the record. What your books need ready: two to three years of the discretionary lines side by side, with a stated reason for any material change.

11. One-time costs sitting inside ordinary operating expense lines

A genuine one-time cost buried inside a routine expense account is worth nothing to you, because a buyer cannot add back what they cannot find. A flood repair inside general repairs and maintenance, a settled claim inside legal, or a failed system implementation inside software all look like normal operating expense to someone reading the ledger for the first time. Each defensible add-back is worth its own value multiplied by whatever the business is priced at, so the cost of not tracking them compounds. What your books need ready: a running add-back log started now, with the invoice attached at the time the cost is incurred. More on which adjustments hold up is in add-backs when selling a business.

12. Other income and other expense, the line nobody looks at

The other income and other expense lines get questioned precisely because they are where miscellaneous items accumulate without anyone deciding they belong there. Insurance proceeds, gains on equipment sales, rebates, forgiven balances, and small unclassified items collect in these accounts and some of them are recurring while some are not. A buyer will not assume in your favor. What your books need ready: the detail behind both accounts for every period shown, with each item labeled recurring or non-recurring.

The Sentence and the Document

The Sentence and the Document is the readiness rule that covers all twelve: every line on this list needs one sentence that explains it and one document that proves the sentence. If a line takes a story to explain, it will take a discount to sell.

The practical form is a single page, built before anyone is in diligence. Twelve rows, one per line above. Column one names the line. Column two holds the sentence, written the way you would say it out loud to a stranger. Column three names the document that supports the sentence and where it lives.

It is a short exercise and it does two things. It tells you now, quietly, which lines you cannot currently explain, at a point where you still have time to fix them. And when a buyer arrives, it converts twelve open questions into twelve answered ones, which is most of the difference between a diligence process that takes weeks and one that takes months.

The lines you cannot fill in are the finding. That is the work.

Where Thryve fits

Most of what makes this page difficult is not accounting skill. It is that the answers were never written down while the year was happening, so a year or two later somebody has to reconstruct them from memory and a filing cabinet. A clean monthly close fixes that at the source: policies stated once and applied consistently, revenue segmented in the ledger rather than in a spreadsheet, allocations documented, and unusual items logged with support attached at the moment they occur.

Thryve Accounting & Advisory builds that close and keeps it running, so the twelve lines above are answerable on any given Tuesday rather than assembled under deadline. When it is time to actually run a sale process, that is M&A execution, and Texas Exit Advisors and Optima Mergers & Acquisitions handle that side.

If you want to know which of the twelve your books can currently answer, that is a short conversation and a useful one.
