In nearly every business sale, the deal doesn’t truly end at closing. Hidden in the fine print of the purchase agreement is one of the most critical—and misunderstood—components of any transaction: the working capital true-up. For sellers, the true-up can mean the difference between collecting the full purchase price or watching a portion quietly evaporate after closing. For buyers, it’s a safeguard to ensure they receive a business that can operate as intended from day one. Managing this process requires precision, documentation, and foresight baked into the deal structure long before signatures hit the page.
The “true-up” is a post-closing reconciliation process designed to confirm that the business’s working capital—current assets minus current liabilities—at the time of closing matches the target agreed upon by the buyer and seller. Working capital ensures the company can fund its day-to-day operations after the sale without the buyer immediately injecting cash.
Because closing dates often fall weeks or months after the valuation date, fluctuations in accounts receivable, inventory, or payables can distort the actual working capital position. The true-up reconciles these movements to keep both sides aligned with the deal’s intended economics.
A typical process unfolds as follows: at closing, the buyer makes a preliminary estimate of working capital. After the transaction, usually within 30 to 90 days, the buyer prepares a closing balance sheet. If the actual working capital exceeds the agreed target, the seller may receive an upward adjustment. If it falls short, the purchase price is reduced accordingly.
Most disputes over true-ups don’t stem from accounting errors but from ambiguity—either in how “working capital” was defined or in how adjustments are calculated and timed. The purchase agreement should define not only what constitutes working capital but also what is explicitly excluded. Common exclusions include cash, debt, or one-time transaction-related items.
Timing is critical. If the agreement allows the buyer 90 days to submit the closing statement, and the seller only 30 days to respond, that imbalance can limit the seller’s ability to challenge questionable adjustments. Both parties should negotiate timelines that allow sufficient time for review and access to the necessary data.
Additionally, the accounting principles used to prepare the closing balance sheet must align with those used historically. Sellers often underestimate how small differences—switching from cash to accrual accounting, or using a different inventory valuation method—can produce major variances in reported working capital. The agreement should specify that the same accounting principles, policies, and consistent classifications will be used both before and after closing.
A well-drafted purchase agreement will outline a detailed roadmap for the true-up. This includes:
- Target Working Capital:
Based on a normalized historical average, typically the trailing 12 months adjusted for seasonality and one-time anomalies. - Estimated Working Capital at Closing:
An initial figure used to set the provisional purchase price at closing. - Post-Closing Statement:
Prepared by the buyer within a defined period (commonly 60–90 days) showing the actual working capital as of the closing date. - Review and Objection Period:
Sellers are given a period (often 30 days) to review and dispute the buyer’s statement. - Resolution Mechanism:
If disputes persist, the matter is typically referred to a neutral accounting firm or arbitrator for a binding determination.
Every one of these steps should be drafted with specificity. The more precise the definitions and timelines, the less room there is for post-closing surprises.
Common Traps and How to Avoid Them
1. Overly Broad Definitions:
A vague definition of working capital can open the door for buyers to include liabilities or exclude assets that weren’t considered during negotiations. Insist on a schedule that clearly itemizes inclusions and exclusions.
2. Inconsistent Accounting Policies:
If the purchase agreement allows the buyer to apply their own accounting methods, the true-up becomes an opportunity for manipulation. Consistency with historical financials must be mandatory.
3. Deferred Revenue and Accruals:
Items like deferred revenue or accrued expenses are often treated differently depending on the buyer’s or seller’s accounting preferences. These need explicit treatment in the agreement.
4. Access to Data:
Sellers should retain access to post-closing financial information during the true-up period. Without it, verifying the buyer’s calculations becomes nearly impossible.
Even the most detailed agreements can’t prevent every disagreement. That’s why the dispute resolution clause is critical. Typically, disputes over the true-up are referred to an independent accounting firm mutually agreed upon by both parties. The firm acts as an expert, not an arbitrator, meaning its decision is final and binding within defined parameters.
The clause should specify the scope of review (limited to disputed items), the standards the firm will apply, the process for submitting evidence, and how fees will be shared. Ambiguity here can lead to procedural battles that outlast the dispute itself.
The working capital true-up isn’t a formality—it’s the last financial negotiation of the deal. Buyers view it as insurance against an underfunded business; sellers see it as a risk of unintended price erosion. The art lies in structuring the purchase agreement to balance both interests with clarity, consistency, and enforceable process.
When handled properly, the true-up protects the integrity of the transaction and the relationship between buyer and seller. When ignored or rushed, it becomes the battlefield where value is quietly won or lost.
