Working Capital Adjustments in Business Sales: What Every Seller — and Buyer — Should Know

If you are considering selling your business — or buying one — you will almost certainly encounter the term “working capital adjustment.” For many business owners, this is one of the most misunderstood aspects of a transaction. It can shift the effective purchase price by tens of thousands of dollars in either direction, yet it rarely receives the attention it deserves during early negotiations.

This article explains what working capital adjustments are, why they matter, and what both sellers and buyers should keep in mind when navigating this part of a deal.

The Basics: What Is Working Capital?

Working capital is a measure of a business’s short-term financial health. At its most fundamental level, it is calculated as:

Working Capital = Current Assets − Current Liabilities

Current assets typically include cash, accounts receivable (money owed to the business by customers), and inventory. Current liabilities typically include accounts payable (money the business owes to vendors and suppliers) and accrued expenses like payroll.

In simple terms, working capital represents the liquidity available for a business to operate day-to-day. When a buyer acquires a business, they expect to receive enough working capital to keep it running without having to inject additional cash from day one. This, of course, is heavily dependent on the industry, business, enterprise value, and a large number of other factors that can lean negotiations towards working capital being inclusive in the transaction.

Why Adjustments Are Necessary

Most purchase agreements for business acquisitions include a working capital adjustment mechanism. Here’s why: a business’s working capital fluctuates constantly. It changes with every invoice sent, every bill paid, and every sale recorded.

The parties negotiate a “target” working capital level — sometimes called the “peg” — that represents the amount of working capital the buyer expects to receive at closing. This target is typically based on a historical average of the business’s working capital over the prior 12 to 24 months.

After closing, the parties compare the actual working capital delivered at closing to the agreed target:

•          If actual working capital is above the target, the buyer pays the seller the difference (the seller delivered more than expected).

•          If actual working capital is below the target, the seller pays the buyer the difference (the buyer received less than expected).

In this example, the seller effectively receives $40,000 less than the headline purchase price because the business was delivered with less working capital than expected.

A Note on Cash

One common source of confusion: in most small and lower-middle-market transactions, cash is excluded from the working capital calculation entirely. The deal is typically structured on a “cash-free, debt-free” basis, meaning the seller takes the cash out of the business before closing, and the buyer receives the business free of funded debt. The working capital peg is then set on the assumption that cash is not being delivered.

This is important for sellers to understand: you are generally entitled to sweep the cash balance prior to closing, but the working capital you deliver — receivables, inventory, payables, and accruals — will still be measured and compared to the agreed target.

What Sellers Should Know

Understand Your Historical Baseline

The working capital peg will likely be based on a trailing average of your financials. If your business has seasonal swings in receivables or inventory, the averaging period matters enormously. A seller whose business carries high inventory heading into a peak season may find that a simple 12-month average underrepresents their “normal” working capital requirement. Push for an averaging methodology that reflects the reality of how your business operates.

 Don’t Manipulate the Numbers Pre-Closing

It may be tempting to accelerate collections, delay vendor payments, or draw down inventory in the weeks before closing in order to extract more cash from the business. Be careful. Buyers and their advisors are experienced at spotting these patterns, and doing so can generate a working capital shortfall that reduces your proceeds dollar-for-dollar at closing — or worse, trigger indemnification claims under the purchase agreement.

Watch the Definitions

Working capital adjustments live and die on definitions. How are receivables aged? Which liabilities are included? How is inventory valued — at cost, net realizable value, or some other measure? These are negotiating points, not boilerplate. An experienced M&A attorney will identify provisions that could expose you to adjustment claims you didn’t anticipate.

 Build In a Collar

A “working capital collar” is a negotiated band within which no adjustment is made. For example, the parties might agree that adjustments only apply if the shortfall or excess exceeds $25,000. For smaller transactions, collars protect both sides from spending more on post-closing disputes than the adjustment itself is worth.

What Buyers Should Know

Verify the Peg Before You Sign

The working capital target should be grounded in the business’s actual historical financials, not the seller’s best month. As part of due diligence, review monthly balance sheets for at least the prior 12 months and calculate working capital for each period. Understand the range, not just the average.

Look for Deferred Revenue

Deferred revenue — money collected by the business for services not yet performed — is a common working capital trap for buyers. If the business has collected customer deposits or prepayments, that amount may appear on the balance sheet as a liability. Make sure the purchase agreement addresses how deferred revenue is treated in the working capital calculation, and ensure you understand the actual obligation you will be stepping into.

Scrutinize Receivables Quality

Not all accounts receivable are created equal. A seller may have $200,000 in outstanding invoices, but if a significant portion is over 90 days old and unlikely to be collected, the receivables are worth far less than face value. Request an aging report and ask about the history of write-offs. Consider negotiating an exclusion for receivables beyond a certain age threshold.

 BUYER TIP: Include a working capital representation in the purchase agreement confirming that, as of closing, the business’s accounts receivable are collectible in the ordinary course, subject to normal reserves. This creates a contractual basis for a claim if uncollectible receivables inflate the working capital delivered at closing.

The Post-Closing True-Up Process

Most purchase agreements provide for a post-closing working capital true-up: within 60 to 90 days after closing, the buyer prepares a closing balance sheet and compares actual working capital to the peg. There is typically a dispute resolution mechanism if the seller disagrees with the buyer’s calculation.

Buyers should be aware that, as the party preparing the closing balance sheet, they bear the burden of doing so accurately and in accordance with the agreed accounting principles. Inflating adjustments or adopting aggressive accounting positions can create legal exposure and damage the post-closing relationship with the seller.

A Practical Example

Suppose a regional HVAC company is being acquired for $2,000,000. The parties agree on a working capital target of $350,000, based on a 12-month trailing average. At closing, the following balances are confirmed:

The effective proceeds to the seller are reduced by $35,000, bringing net proceeds to $1,965,000. This outcome is not unusual — and it illustrates why sellers should not wait until closing to pay attention to their working capital position.

The Bottom Line

Working capital adjustments are a routine — and important — part of nearly every business acquisition. For sellers, understanding the mechanism early gives you the opportunity to negotiate favorable terms, manage your balance sheet intelligently, and avoid unwelcome surprises at the closing table. For buyers, the working capital analysis is a critical component of due diligence that directly affects the true cost of the acquisition.

Neither side should treat the working capital section of a purchase agreement as boilerplate. A few well-negotiated provisions — or a few overlooked ones — can meaningfully change the economics of the deal.
