- Most negotiations set a price based on financial statements that are already a few weeks or months old by the time of closing.

The price written on the front page of a business purchase agreement is almost never the exact amount that changes hands. Between signing and closing — and often for weeks afterward — the business keeps operating, invoicing customers, paying suppliers, and carrying inventory. A purchase price adjustment clause exists to true up the headline price to reflect what the business actually looked like on the day it changed hands, not on the day the deal was negotiated.
For a first-time buyer or seller, this can be the most confusing part of the agreement — it looks like fine print, but it can move the final cheque by a meaningful amount. Understanding the mechanics before you sign helps you negotiate it properly instead of being surprised by it later.
Why the Purchase Price Isn't Fixed on Signing Day
Most negotiations set a price based on financial statements that are already a few weeks or months old by the time of closing. In the gap between signing and closing, and sometimes for a defined period after, the business's cash, receivables, payables, and inventory keep moving. A purchase price adjustment clause allocates that movement fairly between buyer and seller instead of leaving one side to absorb it by accident.
This is standard in both asset purchases and share purchases, though what gets measured differs slightly depending on which structure your deal uses.
How a Working Capital Adjustment Typically Works
A working capital adjustment is the most common form of purchase price adjustment. It generally follows a sequence like this:
- Target set at signing. The parties agree on a "target" level of net working capital (current assets like receivables and inventory, minus current liabilities like payables) that the business is expected to have at closing.
- Estimated closing statement. Shortly before closing, the seller prepares an estimate of what working capital will actually be, and the price is adjusted up or down from the target based on that estimate.
- Final closing statement. After closing, once the books for the closing date are finalized, a final statement is prepared — often within an agreed number of days.
- True-up payment. The difference between the estimated and final figures is settled with a payment from buyer to seller, or seller to buyer, depending on which way the number moved.
The purchase agreement should spell out exactly which accounts count toward "working capital," what accounting policies apply, and who has the right to review supporting records during the process.
Estimated vs. Final Closing Statements
| Stage | What It Reflects | Typically Prepared By |
|---|---|---|
| Target working capital | Negotiated benchmark, set before or at signing | Both parties, by agreement |
| Estimated closing statement | Seller's best estimate as of the closing date | Seller (or seller's accountant) |
| Final closing statement | Actual, finalized figures after closing | Seller, subject to buyer review |
| True-up | The reconciling payment between estimate and final | Whichever party owes it |
A well-drafted clause gives the buyer a defined window to review and dispute the final statement, rather than simply accepting whatever the seller submits.
Other Ways the Price Can Move After Closing
Working capital is not the only adjustment mechanism you may see in an Ontario business purchase agreement:
- Holdbacks or escrow. A portion of the purchase price is withheld or placed with a third party for a defined period, to secure the buyer's ability to make a claim under the seller's representations, warranties, and indemnities.
- Earn-outs. Part of the price is contingent on the business hitting agreed-upon future performance, and is calculated and paid out after closing based on actual results.
- Debt-and-cash-free adjustments. In many deals, the price is negotiated on a "debt-free, cash-free" basis, meaning the seller's cash is excluded from the sale and outstanding debt is deducted from the price at closing — a related but distinct mechanic from the working capital adjustment.
Each of these should be drafted with precise definitions, because vague language is where post-closing disputes usually start.
When Buyer and Seller Disagree on the Adjustment
Disagreements over the final working capital number, or over an earn-out calculation, are among the most common post-closing disputes in business sales. A carefully drafted agreement anticipates this and sets out how disputes get resolved — commonly by referring purely financial or accounting disagreements to an independent accountant for a binding determination, while reserving other kinds of disputes for arbitration or the courts. Deciding this mechanism in advance, while both sides are still cooperative, is far cheaper than negotiating it after a dispute has already started.
Frequently asked questions
Does a purchase price adjustment clause apply to every business sale?
Not automatically — it depends on how the deal is negotiated and drafted. Working capital adjustments are extremely common in mid-sized business sales, but very small or simple transactions sometimes settle on a fixed price with no post-closing adjustment at all.
What happens if the final number is lower than the target?
If closing-date working capital comes in below the agreed target, the purchase price is typically reduced, and the seller may owe the buyer the difference. The reverse is also true — a higher-than-target figure usually increases what the buyer owes the seller.
Can the adjustment period be open-ended?
No — a properly drafted agreement sets specific deadlines for delivering the estimated statement, delivering the final statement, disputing it, and resolving any dispute. Open-ended adjustment mechanics create unnecessary uncertainty for both sides.
Is a working capital adjustment the same as an earn-out?
No. A working capital adjustment corrects for short-term timing differences in cash and operating accounts around the closing date. An earn-out is a longer-term mechanism tied to the business's future performance after the buyer takes over, and works quite differently.
