When a business is sold, what happens to accounts payable depends almost entirely on how the deal is structured. In an asset sale, the seller’s entity keeps the unpaid vendor bills unless the buyer expressly agrees to take specific ones on. In a stock sale, every payable stays inside the company and transfers automatically to the new owner along with everything else on the balance sheet. That single distinction drives the purchase price, the negotiation, and each side’s exposure to bills nobody wants to pay twice.
Why Deal Structure Decides the Answer
Acquisitions take one of two basic forms. In an asset sale, the buyer picks specific assets (equipment, inventory, customer lists, intellectual property) and agrees to take on only the liabilities spelled out in the purchase agreement. The seller’s legal entity stays intact and still owes whatever debts it incurred before closing.
In a stock sale, the buyer purchases the ownership interest in the company itself, whether shares of a corporation or membership units of an LLC. The entity doesn’t change hands; it just gets a new owner. Every asset and every liability, including every unpaid invoice, stays inside that entity by default.
Everything else, from price adjustments to indemnification, flows from that choice.
Accounts Payable in an Asset Sale
The default rule in an asset sale is straightforward. The buyer does not inherit the seller’s unpaid bills. The seller’s entity incurred the debt and remains responsible for paying it. Any obligation the buyer takes on must be listed explicitly in the purchase agreement. If an invoice isn’t on that list, it stays with the seller.
Buyers often agree anyway to assume some portion of the payables, and for a practical reason. If the buyer is taking over operations, it needs vendor relationships intact. A supplier who shipped $200,000 in raw materials last month doesn’t care about the legal structure of your deal; they care about getting paid. Assuming that obligation protects the supply chain from disruption.
How Assumed Payables Move the Price
When a buyer agrees to take on specific payables, the purchase price typically drops by the same amount. If the agreed price is $10 million and the buyer assumes $500,000 in accounts payable, the cash payment to the seller falls to $9.5 million. The buyer is paying $500,000 of the price directly to the seller’s vendors instead of to the seller.
The agreement needs to itemize exactly which invoices, vendors, and dollar amounts the buyer is picking up. Language like “buyer assumes all trade payables” invites disputes. Better practice is an exhibit listing every invoice by vendor name, date, and amount. Anything not on the list stays with the seller.
When the Seller Keeps the Payables
When the seller retains the payables, the agreement should explicitly exclude the buyer from responsibility. The seller then uses sale proceeds or other capital to settle the outstanding balances. This looks clean on paper but creates a risk: if the seller takes the money and doesn’t pay, vendors may come knocking on the buyer’s door, especially when the buyer is now running the same business at the same location with the same employees.
Those vendors have no legal claim against the buyer for the seller’s retained debts in a properly structured asset sale. But a vendor who doesn’t get paid may refuse to extend credit, hold future shipments, or create operational headaches that cost more than the original invoice. Careful buyers require the seller to pay down critical vendor balances at or before closing, sometimes directly from escrow funds.
Accounts Payable in a Stock Sale
A stock sale is simpler in one respect and more dangerous in another. The company’s legal entity doesn’t change, so every payable on the books at closing stays exactly where it is. No assumption agreement, no itemized list, no question about who owes what. The entity owes the same debts it always did. It just has a new owner writing the checks.
The negotiation shifts from “who pays this bill” to “how does this bill affect what the company is worth.” Accounts payable reduces net working capital, which reduces the equity value the buyer is willing to pay. A company with $3 million in current assets and $1.5 million in current liabilities has net working capital of $1.5 million. If payables were $2 million higher instead, net working capital drops accordingly, and the purchase price follows.
That creates an incentive problem. A seller might be tempted to delay paying vendors, letting cash build while payables balloon. The cash looks good on the balance sheet, but the offsetting liabilities eat into working capital. Buyers counter this with adjustment mechanisms built to catch exactly that maneuver.
The Working Capital True-Up
Most acquisition agreements don’t lock in a final price at signing. The parties agree on a preliminary price based on estimated working capital, then true it up after closing once they can examine the actual numbers.
The mechanics: during negotiations, the parties agree on a “target” working capital figure, usually based on a trailing average of the company’s monthly working capital over the prior 12 to 24 months. At closing, the buyer pays a preliminary price based on estimated working capital. Then, typically within 60 to 120 days after closing, the buyer prepares a detailed closing balance sheet showing actual working capital as of the closing date.
If actual working capital exceeds the target, the buyer owes the seller the difference. If it falls short, the seller owes the buyer. Because accounts payable is one of the largest current liability line items, any unexpected spike in payables directly reduces working capital and triggers a payment back to the buyer. This is where sellers who stretched their vendors before closing get caught. The inflated cash balance is offset by the inflated payables, and the adjustment neutralizes the manipulation.
Successor Liability: When an Asset Buyer Gets Stuck Anyway
The general rule is that an asset buyer doesn’t take on the seller’s debts. Courts have carved out exceptions that can override the purchase agreement entirely. Buyers who treat the asset structure as an absolute shield sometimes learn it has holes.
Four widely recognized exceptions can make an asset buyer liable for the seller’s unpaid obligations:
- Express or implied assumption, where the buyer’s conduct or the agreement’s language indicates the buyer took on the liabilities, even if the parties didn’t intend that result.
- De facto merger, where the transaction looks like a merger in substance despite being labeled an asset sale. Courts examine continuity of management, personnel, location, and operations; whether the seller dissolved after closing; and whether the buyer paid with its own stock rather than cash.
- Mere continuation, where the buyer is essentially the same entity as the seller wearing a different name: same owners, same management, same operations.
- Fraudulent transfer, where the sale was structured to put assets beyond the reach of creditors, or the seller received less than fair value for what it sold.
Most disputes land in the de facto merger doctrine. A buyer that acquires all of a seller’s assets, hires all of the seller’s employees, continues operating the same business at the same location, and watches the seller dissolve shortly after closing has a weak argument that the transaction was “just” an asset sale. Courts in that situation look at economic reality, not the label on the agreement.
Verifying Payables Before You Close
The best time to catch problems with accounts payable is before closing. Buyers who skip a detailed payables review during due diligence are writing a blank check for liabilities they haven’t verified.
The aging schedule is the first document to examine. It breaks down outstanding payables by how long they’ve been unpaid, typically in 30-day buckets: current, 30 days past due, 60, 90, and beyond. Heavy concentration past 90 days signals either financial distress or vendor disputes. Either one is a risk.
Beyond the aging report, look for:
- Unrecorded liabilities. Goods or services received before closing but not yet invoiced. Real obligations, but not on the ledger yet.
- Disputed invoices. Amounts the seller is contesting. If the buyer assumes these, it inherits the dispute along with the bill.
- Related-party payables. Amounts owed to the seller’s owners, family members, or affiliated companies. These can be inflated or carry terms that don’t reflect arm’s-length transactions.
- Seasonal patterns. A snapshot on a single date can mislead if the business has seasonal purchasing cycles. Multiple months of aging reports give a truer picture.
Confirming balances directly with major vendors is the most reliable check. If the seller says it owes Vendor X $150,000 and Vendor X says the balance is $210,000, you’ve found a problem worth resolving before closing rather than after.
Indemnification and Escrow
Purchase agreements include indemnification clauses that require the seller to reimburse the buyer for losses caused by breaches of the seller’s representations, including misstatements about accounts payable balances. If the seller represented that total payables were $800,000 and the buyer discovers $1.1 million in actual obligations after closing, the indemnification clause gives the buyer a contractual right to recover the $300,000 difference.
Collecting is the harder part. A seller who pocketed the sale proceeds and moved on may not have the assets or the inclination to pay a claim. Escrow accounts solve this by holding back a portion of the purchase price with a neutral third party. Holdbacks in private company deals commonly range from 10% to 25% of the purchase price, held for a warranty period that can last from several months to a few years. If the buyer files a valid claim, the escrow agent pays it from the held funds without the buyer chasing the seller through litigation.
The size and duration of the escrow should reflect the risk level of the payables. Clean, well-documented payables and strong vendor relationships warrant a smaller holdback than disputed invoices, aging balances past 90 days, and a history of accrued-but-unrecorded liabilities.
Keeping Vendors Paid Through the Transition
Regardless of structure, someone has to keep paying vendors on time after closing. Gaps in payment during the transition can damage credit relationships that took years to build, trigger credit holds, and disrupt supply chains at the worst possible moment.
In an asset sale, vendors need to know who’s paying their outstanding invoices. If the seller retained the payables, the seller should notify each vendor directly, confirm the amounts, and commit to payment timelines. If the buyer assumed specific invoices, the buyer should introduce itself to those vendors, confirm the assumed balances, and provide new payment contact information. Silence breeds confusion, and confused vendors stop shipping.
Stock sales are simpler operationally because the entity that owes the money hasn’t changed. Vendors send invoices to the same company at the same address. The buyer’s main task is making sure the payment function continues without interruption, which means getting access to the seller’s accounting systems, payment schedules, and vendor contact lists well before closing.
The purchase agreement should also divide responsibility for disputes based on when the underlying goods or services were received. The seller handles disputes about deliveries made before closing; the buyer handles everything after. Without that bright line, both sides point fingers while the vendor waits for payment and eventually takes its business elsewhere.
