You agree to sell your business for $2 million. At closing, the buyer adjusts the price down by $85,000 because working capital came in below the target. You did not steal the money. You collected receivables, paid down payables, and ran a tighter operation, which is what any good owner does. But the purchase agreement treated that as a reduction in price. Working capital adjustments catch more sellers off guard than almost any other clause in the deal.

What working capital means in a business sale

Working capital is the money tied up in the day-to-day operation of the business: accounts receivable, inventory, prepaid expenses, minus accounts payable and accrued liabilities. It is the financial fuel that keeps the business running between cash cycles.

When you sell a business, the buyer expects to acquire enough working capital to operate from day one without injecting additional cash. If you drain working capital before closing by collecting every receivable, delaying vendor payments, or running down inventory, the buyer inherits a business that needs an immediate cash infusion. The working capital adjustment exists to prevent that.

How the adjustment works

The LOI or purchase agreement sets a working capital target, usually based on a trailing average. A common approach is the average working capital over the last twelve months, calculated at closing based on the most recent balance sheet.

At closing, the parties calculate actual working capital. The difference between actual and target flows through to the purchase price:

  • Actual equals target: No adjustment. You receive the agreed price.
  • Actual is below target: The price is reduced by the shortfall. If target is $200,000 and actual is $150,000, the price drops by $50,000.
  • Actual is above target: The price increases by the surplus. If actual is $240,000, you receive an additional $40,000.

The adjustment is typically calculated within 60 to 90 days after closing, once final accounting is complete. Some deals include a holdback or escrow to cover potential disputes over the calculation.

What is included in working capital

Definitions vary by deal, which is why this clause needs careful attention. A typical working capital calculation for a Main Street business includes:

  • Included: Accounts receivable (often net of a reserve for bad debt), inventory at cost, prepaid expenses, security deposits.
  • Excluded: Cash and cash equivalents (usually handled separately), short-term debt, deferred revenue, sales tax payable, intercompany balances.
  • Subtracted: Accounts payable, accrued payroll and benefits, accrued expenses, customer deposits.

The exact definition is negotiated in the purchase agreement. Items like obsolete inventory, related-party receivables, and disputed accounts can become negotiation points if not defined upfront.

The mistakes sellers make

1. Collecting receivables aggressively before closing

You know you are selling, so you push customers to pay outstanding invoices. Receivables drop. Working capital drops. The adjustment costs you money for doing what felt responsible.

2. Delaying vendor payments

Stretching payables before closing increases cash in the bank but reduces working capital. The buyer sees the shortfall and adjusts the price. The cash you collected is offset by the price reduction.

3. Running down inventory

Stopping reorders to avoid carrying excess inventory at closing reduces working capital. If the buyer needs that inventory to serve customers, the shortfall comes out of your price.

4. Not understanding the target

Many sellers sign an LOI without understanding what the working capital target number is or how it will be calculated. They are surprised at closing when the adjustment appears.

5. Treating cash as theirs

Cash on the balance sheet at closing is usually excluded from working capital and retained by the seller. But if you confuse cash with working capital and drain receivables to boost cash, you may gain in one column and lose in another.

How to protect yourself

  1. Calculate the target before you sign the LOI. Have your CPA model working capital under the proposed definition using your last twelve months of balance sheets. Know the number.
  2. Negotiate the definition. Push for clear, specific language on what is included and excluded. Exclude obsolete inventory, related-party items, and anything that distorts the normal level.
  3. Negotiate the target level. If the trailing average includes an unusual period, argue for a normalized target that reflects steady-state operations.
  4. Run the business normally during the sale process. Do not artificially inflate or deflate working capital. Maintain normal collection cycles, payment terms, and inventory levels.
  5. Monitor monthly. From LOI to closing, track working capital against the target. If you are drifting, you can correct course before closing rather than being surprised.
  6. Negotiate a collar. Some deals include a tolerance band (e.g., plus or minus $25,000) where no adjustment is made. Push for this.

A worked example

A York County HVAC company sells for $1.8 million. The working capital target, based on the trailing twelve-month average, is $175,000.

During the three-month due diligence period, the owner collects receivables aggressively ($40,000 above normal), delays a vendor payment ($15,000), and does not reorder parts ($20,000 inventory reduction). Actual working capital at closing: $100,000.

Shortfall: $75,000. Adjusted price: $1,725,000. The owner thought they were being financially disciplined. Instead, they gave back $75,000 of the sale price.

If the owner had maintained normal operations, working capital would have been approximately $170,000, and the adjustment would have been negligible.

The working capital adjustment is not a penalty. It is a mechanism to ensure the buyer gets a business that can operate on day one. The seller's job is to understand the math before signing.
