Working Capital and Normalized Earnings: What Moves the Price

Why reported profit is not what a buyer pays for

Small business tax returns and bookkeeping are built to minimize taxable income, not to show a buyer what the business actually earns. Owners run personal expenses through the company, pay themselves however works best for payroll taxes that year, and sometimes structure the balance sheet around family or related-party arrangements that have nothing to do with how a new, unrelated owner would run things. None of that is dishonest — it is just how most privately held businesses operate.

Normalizing earnings means rebuilding the profit and loss statement to reflect what the business would earn under normal, professional, arm's-length operation, starting from net income or EBITDA and adding back or removing items that a new owner would not experience the same way. The result, often called seller's discretionary earnings (SDE) for smaller businesses or adjusted EBITDA for larger ones, is the number buyers actually apply a multiple to. Get this number wrong, in either direction, and every multiple applied to it produces a distorted price.

This is also where trust is built or lost fastest. A buyer's advisor will comb through every add-back proposed, and clean, well-documented adjustments move through diligence faster and closer to the original price than a schedule that becomes a fight.

What buyers typically accept as add-backs

Owner's compensation above what a replacement manager would actually cost is the largest and most universally accepted add-back for an owner-operated business. If the owner draws $250,000 a year but a qualified general manager to replace them would cost $90,000, the $160,000 difference is generally added back, because a buyer stepping in either does that job themselves or hires someone at market rate, not at the owner's historical draw.

Beyond compensation, commonly accepted add-backs include: personal expenses run through the business (a personal vehicle, family health insurance, travel that wasn't for business purposes, a country club membership); one-time or non-recurring items (a lawsuit settlement, a one-off equipment repair after a flood, moving costs for a single relocation, COVID-era relief that won't recur); non-cash expenses like depreciation and amortization; interest expense on debt that won't transfer with the sale; and above-market related-party rent, where the owner also owns the building and charges the business more than fair market rent.

The common thread across all of these is that a buyer, operating the business independently and at arm's length going forward, would not incur the expense in the same way. Add-backs are not about making the business look better than it is — they're about showing what it would actually earn under normal ownership.

What buyers push back on or reject outright

Buyers and their advisors are skeptical of add-backs that shift a real, recurring cost onto the buyer without adjusting anything else. A common one: if owner's compensation is added back in full but no offsetting cost is deducted for the market-rate manager who will have to run the business after the owner leaves, the buyer is effectively being asked to pay for the owner's labor twice — once in the price, and again when they hire someone to replace it. A defensible add-back nets the excess draw over a reasonable replacement salary, not the full amount.

Vague or undocumented add-backs get rejected fast. "Miscellaneous personal expenses, $40,000/year, estimated" with no receipts, no consistent methodology, and no support across multiple years reads as an attempt to inflate earnings rather than a legitimate normalization, and it damages the credibility of every other add-back on the list, even the reasonable ones. Buyers also generally reject add-backs for expenses that, while framed as one-time, actually recur most years in different forms — a new roof this year, a new truck last year, a lawsuit the year before that is really just the ordinary cost of running the business.

Related-party rent adjustments get particular scrutiny in both directions. If the owner is charging the business below-market rent and plans to keep the real estate after the sale, the buyer will often normalize rent upward to market rate, which reduces earnings and, by extension, the price — the opposite of what an owner assembling add-backs typically hopes for. Sellers who own the building and expect to lease it back to the buyer should model both sides of that adjustment before going to market, not discover it during diligence.

The broader lesson: a sloppy or aggressive add-back schedule costs more than the disputed dollars — it signals the rest of the financials may need the same scrutiny, slowing diligence and sometimes reducing buyer confidence enough to affect price.

Cash-free, debt-free and where working capital fits in

Most business sales, whether asset or stock deals, are priced on a cash-free, debt-free basis. This means the agreed purchase price assumes the seller keeps the cash sitting in the business's bank accounts and pays off (or keeps) any interest-bearing debt themselves; those items are settled separately from the operating price of the business. What the buyer is actually buying, at that price, is the operating business itself, along with a normal, functioning amount of working capital to run it from day one.

That's where the net working capital (NWC) adjustment comes in. Working capital is the short-term operating fuel a business needs: enough receivables in the pipeline, enough inventory on the shelf, enough prepaid expenses covering near-term needs, net of the payables and accrued expenses the business owes. If a seller could strip the business of all its receivables and inventory right before closing while leaving payables behind, the buyer would show up on day one unable to fill orders, pay vendors, or collect what's owed — even though the purchase price didn't change. The NWC mechanism exists specifically to prevent that.

What counts, how the peg is set, and the true-up

Net working capital for deal purposes is typically defined as current assets minus current liabilities, with cash and debt excluded (since those are handled separately in a cash-free debt-free deal). On the asset side, that usually includes accounts receivable, inventory, and prepaid expenses. On the liability side, it usually includes accounts payable and accrued expenses like accrued payroll, accrued vacation, and sales tax payable. The exact definition is negotiated and spelled out in the purchase agreement — it is not automatic, and disputes over what should or shouldn't be included are common enough that the definition deserves real attention before signing.

The target amount, called the peg, is usually calculated as the average net working capital the business has carried over a trailing period, commonly the trailing twelve months, to smooth out normal month-to-month swings. The idea is simple: the buyer should receive, at closing, an amount of working capital in line with what the business has normally operated with, not an inflated or stripped-down snapshot chosen to favor one side.

At closing, the parties use an estimate of NWC based on the most recent available numbers, and the price is adjusted up or down at closing for any difference from the peg. Then, because closing-date numbers are rarely final — checks are still clearing, invoices are still coming in, month-end accruals haven't been booked — the deal includes a true-up period, typically 60 to 120 days after closing, during which the actual closing-date NWC is calculated properly and reconciled against both the peg and the closing estimate. If actual NWC delivered was below the peg, the seller owes the buyer the difference; if it was above the peg, the buyer owes the seller the difference. This true-up is a normal, expected part of almost every deal of meaningful size — not a sign that something went wrong.

A hypothetical peg calculation and true-up

None of the figures below describe a real transaction; they illustrate how the math works. Say a hypothetical distribution company's trailing-twelve-month average net working capital, calculated monthly, comes out to: average AR of $420,000, average inventory of $310,000, average prepaid expenses of $20,000, average AP of $180,000, and average accrued expenses of $40,000. The peg is (420,000 + 310,000 + 20,000) − (180,000 + 40,000) = $530,000.

At closing, the parties use an estimated closing-date NWC of $545,000, based on the most recent available balance sheet, so the buyer pays an extra $15,000 above the base purchase price at closing to reflect the working capital delivered above the peg.

Ninety days later, the true-up calculation is finalized: actual closing-date AR turns out to be $400,000 once a few old receivables are written off as uncollectible, inventory is confirmed at $300,000 after a physical count finds some shrinkage, prepaid expenses are $20,000, AP is $190,000 (a few invoices arrived late), and accrued expenses are $45,000. Actual closing-date NWC = (400,000 + 300,000 + 20,000) − (190,000 + 45,000) = $485,000. Since actual NWC ($485,000) came in $45,000 below the closing estimate ($530,000 combined peg plus the $15,000 already paid, i.e. the buyer was credited for $545,000 worth of working capital but only received $485,000), the seller owes the buyer $60,000 in the true-up ($545,000 minus $485,000), on top of already being $15,000 below the peg itself relative to what was paid at closing. This kind of gap is exactly why sellers should track receivable collectability and inventory accuracy carefully in the months leading up to a sale, not just at the moment of closing.

Seasonality, deferred revenue, and other traps

Seasonal businesses face a specific trap: working capital naturally swells and shrinks across the year, so a peg calculated from a trailing twelve-month average may not match the actual level of working capital present at the specific time of year the deal happens to close. A landscaping company closing right before its busy season, with inventory and prepaid deposits stocked up for spring, will look very different from the same company closing in the dead of winter. Sellers of seasonal businesses should push to confirm the peg methodology accounts for this, sometimes through a seasonally adjusted target or a closing timed to a more representative point in the cycle, rather than accepting a flat trailing-average peg that happens to fall at an unfavorable moment.

Deferred revenue and customer deposits are another area that catches sellers off guard. If customers have paid in advance for services not yet delivered — a service contract prepaid annually, a deposit for a custom job not yet completed — that money sits on the balance sheet as a liability, because the business still owes the customer the work. Buyers typically want deferred revenue and customer deposits included as a liability in the NWC calculation, since the buyer is the one who will actually have to deliver on the obligation after closing, using their own resources, even though the seller collected the cash beforehand. Sellers sometimes push back that this cash is effectively already spent and shouldn't be treated as a working capital liability at all; how it's handled is negotiated and should be addressed explicitly in the purchase agreement, not left to interpretation after the fact.

Finally, the timing and definition of the NWC calculation should be locked down in writing well before closing — the specific accounts included, the accounting method used (cash versus accrual), how bad debt and inventory obsolescence are handled, and who performs the true-up calculation and how disputes get resolved (often through an independent accountant if the parties can't agree). Sellers who leave this vague, assuming "we'll work it out fairly," consistently end up on the losing side of the negotiation once real numbers and real incentives are on the table after closing, when the buyer already controls the business and the seller's leverage has largely disappeared.
