What it means
When you buy a business, you are not just buying equipment and property. You are also buying day-to-day operations, which means taking over customer unpaid invoices, stock on shelves, and supplier bills.
These items make up working capital. Buyers and sellers usually agree on a target level of working capital required to keep the business running normally without needing an immediate cash injection.
On the day the sale completes, the accountants calculate the actual working capital in the business. If the business has more cash, stock, and customer payments than the agreed target, the final purchase price goes up.
The seller is rewarded for leaving extra operational cushion inside the company. Conversely, if the actual working capital falls below the target because inventory is depleted or bills are piling up, the purchase price goes down.
This adjustment protects the buyer from having to pump their own money into the business immediately just to pay suppliers and keep the lights on. Negotiating this clause is critical during company sales.
Disagreements often arise over how inventory is valued or whether certain debts should be included. Clear definitions set out in the purchase agreement prevent painful disputes and ensure a fair deal for both sides.
Buying a car with a full tank of petrol versus an empty one. If the seller leaves the tank full, you pay a bit extra.
If the tank is empty, you negotiate a discount to cover the fuel you need to buy.
In practice
Real-world examples
Example 1
You buy a coffee shop. The target working capital is $10,000. At handover, milk and coffee stocks are low, leaving only $7,000. The purchase price drops by $3,000 so you can restock, and the seller accepts this because the stock was below the agreed level.
Example 2
An engineering firm is sold with a target working capital of $50,000. At completion, strong sales mean customer payments push the actual total to $58,000. The buyer pays an extra $8,000, because it receives more cash and receivables than it expected.
Example 3
A software agency is acquired. The target is $20,000. Due to delayed client payments and unpaid server bills, the actual working capital is $12,000. The final price decreases by $8,000, and the buyer uses the saving to settle the overdue server bills.

Formula
Calculation
Working Capital Adjustment = Actual Working Capital at Completion - Target Working Capital. Final Purchase Price = Headline Price + Working Capital Adjustment. For example, if actual working capital is $45,000 and the target is $50,000, the adjustment is minus $5,000, reducing the final purchase price by $5,000.
Applying this to a deal with a headline price of $1,000,000, the buyer pays $1,000,000 - $5,000 = $995,000. If instead actual working capital had been $56,000, the adjustment would be +$6,000 and the buyer would pay $1,006,000.Case study
Seen in the real world
GreenLeaf Landscaping, a fictional garden maintenance firm, was acquired by a larger regional rival, Apex Grounds. During initial talks, both parties agreed that GreenLeaf needed $30,000 in working capital, covering unpaid customer invoices and lawnmower fuel stocks, to operate without disruption. On completion day, the accountants reviewed the ledger. GreenLeaf had successfully collected several large client invoices just before the sale, raising their actual working capital to $38,000. Because Apex was receiving a business with $8,000 more operational cushion than originally targeted, the final purchase price was adjusted upward by $8,000.
Conversely, if poor collections had left GreenLeaf with only $22,000, Apex would have paid $8,000 less. This mechanism ensured a fair transaction, leaving GreenLeaf's owner fairly compensated for the extra cash left behind while protecting Apex from funding gaps. With a headline price of $400,000, Apex paid an estimated $408,000 on completion day. The accountants then prepared a final statement within the agreed 60 days, and both sides settled any small difference in cash. The agreement defined each item in advance, including how to value fuel stock, so there were no arguments over the final figure.
Watch out
Common mistakes
- Failing to define target working capital using historical seasonal averages.
- Ignoring how inventory is valued, leading to disputes over obsolete stock.
- Confusing working capital adjustments with debt deductions in the purchase price.
Questions
People also ask
Who benefits from a working capital adjustment?
Both parties benefit because it ensures a fair price. The buyer is protected from hidden cash shortages, while the seller gets paid for any excess cash or stock left in the business.
Is working capital the same as cash?
No. Working capital includes cash, but it also includes money owed by customers, inventory, and money owed to suppliers.
When is the adjustment calculated?
An initial estimate is made on completion day, followed by a final reconciliation usually within sixty to ninety days after the sale.
