Key Insight
Sellers approaching a sale sometimes let accounts payable build up — paying vendors more slowly to keep cash longer. The result: the buyer acquires a business with an artificially inflated AP balance and faces an immediate cash drain paying it down.
AP in Working Capital Analysis
Accounts payable is subtracted in the working capital calculation (current assets − current liabilities). Higher AP reduces working capital, which could trigger a downward purchase price adjustment at closing if AP exceeds the normalized target.
This creates an incentive for sellers to delay payments before closing — the higher the AP, the lower the working capital delivered, and the lower the adjustment the seller owes. Buyers should request an AP aging report and compare it to prior periods to detect unusual buildup.
AP Aging
Just as AR aging reveals collection risk, AP aging reveals payment behavior:
- Significant past-due payables may indicate cash flow stress
- Overdue vendor balances can create supply chain issues post-close
- Some vendors may cut off credit or demand upfront payment if they're owed too much
AP in Asset Sales
In most asset sales, existing accounts payable stay with the seller — the seller is responsible for paying its outstanding vendor balances from closing proceeds. However, the AP balance affects the working capital calculation and the effective purchase price.
