A business sale agreement has a headline number (the purchase price) and a list of mechanisms that adjust that headline number at closing. Working capital is usually the largest of those mechanisms. A target is set during negotiation, the company's actual working capital at closing is measured against the target, and the purchase price is adjusted up or down by the difference. The headline number on the deal announcement is rarely the number that arrives in the seller's account.
For owners preparing to sell a business, the working capital target is a topic where careful advisor coordination pays off well before the closing date. This article is an educational overview of the questions worth raising with your accounting, legal, and transaction advisors during the months leading up to a sale. It does not provide tax, legal, accounting, or financial advice; every decision discussed here should be reviewed with appropriately licensed professionals familiar with your specific situation.

Why the working capital target exists at all
A business is sold based on a steady-state assumption: the buyer is paying for a going concern that has the working capital it needs to run normally. Working capital, in the simplest framing, is current assets (cash, receivables, inventory) minus current liabilities (payables, accrued expenses, short-term debt) that the buyer will inherit on day one.
If the seller sweeps cash, collects receivables aggressively, or delays paying vendors in the weeks before closing, the business is delivered to the buyer with less working capital than the buyer expected. The buyer has to inject capital after closing to get the business back to a normal operating level, which means the buyer effectively paid more than the agreed-upon price.
The working capital target, agreed in advance and measured at closing, prevents this. It is the contractual mechanism that says: at closing, the company will have at least $X of working capital, measured a specific way. If actual working capital is less than the target, the buyer's purchase price drops by the shortfall. If actual is more, the buyer pays additional. The mechanic is mechanical; the disputes are about how the components are measured.
The broader context is covered in concept at the Wikipedia entry on working capital. For owners new to M&A mechanics, this is a useful starting point before substantive conversations with advisors.
Topic 1: how the target is being set
The most consequential single question is how the target number was chosen.
The conventional approach is to use a trailing twelve-month average of monthly working capital, computed from monthly balance sheets, normalized for known one-time items. The logic is that twelve months smooths out seasonality and captures a defensible "normal" level. Different deals use different windows (six months, eighteen months, three years), different normalizations, and different definitions of which line items count as working capital.
Topics to raise with your CPA and transaction advisor: which months are included, which line items are included, what normalizations have been agreed, and how seasonality is being handled. A retail business that does 40% of its annual sales in December has a very different working capital profile in November than in February; a flat trailing-twelve-month average can mask this. The conversation about which methodology is appropriate is one where having coordinated, independent counsel matters.
Topic 2: what counts as working capital
The definition section in the purchase agreement decides which balance sheet line items are inside the working capital calculation and which are outside.
Common items inside: trade receivables, inventory, prepaid expenses on the asset side; trade payables, accrued expenses, customer deposits on the liability side.
Common items outside: cash and cash equivalents (often handled by a separate cash-free debt-free purchase price mechanism), interest-bearing debt (handled by the debt mechanism), deferred taxes, income tax accruals, and various transaction-related accruals.
The line items in dispute vary by industry. Software companies argue about deferred revenue. Manufacturing companies argue about WIP inventory valuation. Service businesses argue about unbilled revenue and accrued payroll. The right framing for an advisor conversation is: which line items are in scope, which are excluded, how each disputed item is being treated, and whether the treatment matches industry norms.
A useful reference for line-item definitions is the standard GAAP framework documented by the Financial Accounting Standards Board. Your CPA can explain how each item flows through the calculation; the explanation should match the definition in the draft purchase agreement.
Topic 3: the measurement period and the dispute resolution mechanism
Working capital is measured at a specific point in time, usually a date close to closing. The mechanics of that measurement (who prepares the closing balance sheet, what accounting policies are used, how long the buyer has to dispute) are negotiated in the purchase agreement.
Topics to clarify with your transaction counsel: who prepares the closing balance sheet, what GAAP conventions are explicitly required, how long the buyer has to issue a notice of disagreement, what happens during the dispute window, and how unresolved disagreements are arbitrated. The standard mechanism is a neutral third-party accounting firm whose decision binds both sides; the selection process for that arbitrator deserves attention before signing.
The dispute resolution mechanism is a place where seller-friendly and buyer-friendly templates differ substantially. Reviewing the draft language with experienced M&A counsel, not general corporate counsel, is where the value shows up. The American Bar Association maintains a model purchase agreement that can serve as a baseline reference for what conventional language looks like.

Topic 4: pre-close behavior and the operating covenants
Between signing and closing, the seller's behavior is constrained by operating covenants that require running the business "in the ordinary course." The covenants are designed to prevent the seller from gaming the working capital calculation in the weeks before measurement.
Topics for advisor review: which behaviors are explicitly prohibited (accelerating collections, delaying payables, drawing down inventory, sweeping cash), which are explicitly permitted (ordinary-course CapEx, ordinary-course distributions to owners up to a defined cap), and how disputes about pre-close behavior are resolved.
The mirror question for sellers is which actions taken in the ordinary course will be characterized as "manipulation" by the buyer post-close. The line is sometimes ambiguous; clarity in the agreement is worth more than clarity in conversation after the fact.

Topic 5: the relationship to other purchase price components
Working capital is one of several mechanisms that adjust the purchase price. The full set typically includes a cash adjustment, a debt adjustment, a transaction expense adjustment, and the working capital adjustment. Each is computed separately, and the seller's net at closing is the sum.
Topics worth modeling with your advisors before signing: how the four adjustments interact under realistic scenarios, how each is paid (at closing in cash, via holdback, via post-close true-up), and what the realistic range of total adjustment looks like across the scenarios.
The model is unsexy work and rarely shown to the seller in clean form during negotiation. Insisting on it before signing is one of the highest-leverage moves a seller can make. An independent advisor matching service can be useful for confirming that the transaction advisor team has the bandwidth to build that model, or for coordinating an independent review.
Topic 6: the working capital peg vs the actual close
The agreed target is the peg. The actual working capital at closing is the actual. The difference is the adjustment. Two adjustment timing mechanisms are common.
Closing date estimate plus true-up. The parties agree at signing on an estimated closing working capital. The purchase price is adjusted up or down at closing by the difference between the estimate and the target. After closing, the buyer prepares the final closing balance sheet, computes actual working capital, and there is a true-up payment in either direction.
Locked box. Less common in US deals; more common in European deals. The purchase price is fixed at signing based on a historical balance sheet, with no post-close working capital true-up but with operating covenants that constrain pre-close behavior tightly.
Topics for advisor review: which mechanism is in the draft, why, and what the trade-offs are for the specific deal. Locked-box deals have different cash-flow implications for sellers; closing-date-estimate deals have different documentation requirements at closing.
Topic 7: industry-specific quirks
A few industries have well-known working capital quirks worth raising specifically.
Software with deferred revenue. Deferred revenue is a liability on the balance sheet but represents cash already collected for services not yet delivered. Whether it counts as a working capital liability has substantial impact on the calculation. Discuss how deferred revenue is treated.
Manufacturing with long-cycle inventory. WIP and raw materials inventory can be a large portion of working capital. Valuation methodologies (FIFO, LIFO, weighted average) affect the closing balance sheet differently. The International Trade Administration maintains industry profiles that can be useful context.
Services with retainer billings. Unearned retainer balances are a liability; whether they are working capital is industry-conventional. Raise the question with your CPA.
In each case, the working capital target should be set with the industry-specific definition explicitly, not by reference to a generic template.

Topic 8: the role of quality of earnings work
A quality of earnings analysis, usually commissioned by the buyer, examines the historical financial statements for adjustments that affect the working capital baseline. A diligence-driven re-baselining of working capital is common; the seller's preparation for this is often the difference between a clean close and a contentious one.
Topics for pre-sale review with your CPA and transaction advisor: what historical adjustments are likely to come up in the buyer's quality of earnings work, which can be addressed proactively, and which should be flagged in your own sell-side quality of earnings analysis. Sell-side QoE work is not universal but is increasingly common for mid-market and larger deals.
What good advisor coordination looks like
The owner does not need to become an expert in working capital mechanics. The owner does need to make sure the right experts are coordinated and asking the right questions. The roster typically includes a transaction-experienced CPA, an M&A attorney (not a general corporate attorney), an investment banker or sale advisor for larger deals, and the owner's existing wealth or financial advisor for the post-close planning side.
The coordination questions are: who is responsible for which part of the working capital conversation, who reviews which draft sections of the purchase agreement, who runs the model, and who explains the model output to the owner in plain language. Without explicit role assignment, gaps emerge between the legal review and the accounting review, and that is where the largest disputes start.
For owners who do not have an existing roster of M&A-experienced advisors, the search itself is a project. Services that focus on advisor verification and credential review (for example, Capivise's questions-to-ask-an-advisor framework) can be a starting point for the criteria that distinguish a transaction-fluent CPA from a general one. The Capivise homepage covers the broader context for how that kind of search is structured.
Closing thought
The working capital target is one of the most underrated topics in a business sale. It rarely appears in the deal announcement, it rarely shows up in the seller's mental model, and it routinely accounts for a substantial portion of the cash at closing.
The questions above are not a substitute for advice from licensed professionals familiar with your specific situation. They are a checklist of topics worth raising early, while there is still time to address them in negotiation. The value of the questions is that they get raised at all.
