A vendor credit is a document a supplier issues that reduces what your company owes them. It works like a negative invoice: rather than adding to your accounts payable balance, it subtracts from it. You typically receive one after returning goods, catching a billing error, negotiating an allowance for damaged merchandise, or earning a volume rebate. No cash moves when the credit is issued; instead, your next payment to that supplier shrinks by the credit amount.
Vendor Credit vs. Refund vs. Purchase Discount
These three get confused constantly, and the differences matter for how you record them.
A refund returns money to your bank account. A vendor credit does not. It sits as a balance on that supplier’s account and offsets a future invoice. Until you use it, no funds have moved.
A purchase discount, like “2/10 Net 30,” is a percentage off the invoice earned by paying early. It’s built into the payment terms from the start and depends entirely on your payment speed. A vendor credit, by contrast, corrects something that already went wrong or compensates you after the fact. The triggers are different, the timing is different, and the accounting entries are different.
Why You Might Receive One
Returned, Defective, or Wrong Goods
The most common trigger. You ordered 500 units, 40 arrived damaged, and you shipped them back. The supplier issues a credit memo acknowledging the return and wiping out the corresponding portion of your original invoice. The same applies when the wrong product arrives or the goods fail to meet agreed specifications.
Billing and Pricing Errors
Overcharges happen constantly in procurement. A supplier invoices you at $12 per unit when the purchase order says $10. A volume discount that should have applied at 1,000 units never gets subtracted. These discrepancies surface during invoice reconciliation, and the supplier corrects them by issuing a credit for the difference. Catching them depends on your AP team’s diligence in matching every invoice against the original purchase order and the receiving report before payment goes out.
Allowances for Damaged Goods
Sometimes returning damaged merchandise isn’t practical. Shipping costs may exceed the value of the goods, or you can still use the items at reduced capacity. The supplier and buyer then negotiate an allowance: you keep the goods at a lower effective price, and the vendor credits the difference. This avoids the logistics of a return while still adjusting the financial record to reflect what the goods are actually worth.
Volume Rebates
Rebates reward purchasing volume rather than correct a problem. A supplier might offer a 3% rebate once your annual purchases cross $500,000. Under GAAP, specifically ASC 705-20, cash consideration received from a vendor is presumed to be a reduction in the purchase price and should reduce cost of sales rather than be recorded as revenue. Rebates that are probable and reasonably estimable should also be factored into inventory valuation as purchases occur, not only when the credit memo finally arrives.
How to Record a Vendor Credit
When the credit memo arrives, enter it into your accounting system and link it to the original purchase order or invoice. The journal entry follows a consistent pattern: debit Accounts Payable to reduce the liability, and credit the account that was originally debited when you recorded the purchase.
Which account receives the credit depends on what the memo is for:
- Returned inventory still on hand. Credit the Inventory asset account. Buy $2,000 of goods and return them, and you debit AP by $2,000 and credit Inventory by $2,000. Your balance sheet now shows less inventory and less owed.
- Goods already sold. Credit Cost of Goods Sold. The items are gone from inventory, so the adjustment flows through COGS and improves gross margin for the period.
- Overcharged service or supply expense. Credit the relevant expense account, whether office supplies, maintenance, or whatever category the original charge hit. Operating expenses drop accordingly.
Classification isn’t optional bookkeeping hygiene. Under ASC 705-20, consideration received from a vendor defaults to a reduction of cost of sales unless it qualifies as payment for distinct goods or services you provided to the vendor, or as reimbursement of specific selling costs you incurred. Misclassifying a credit that should reduce COGS as a reduction in operating expenses (or the reverse) distorts your gross margin, your operating margin, or both. Auditors look for exactly this error.
Applying the Credit to Future Payments
Once recorded, the credit sits as a negative balance within that vendor’s AP sub-ledger. You have two practical options for using it.
The most common approach is to apply it against the next outstanding invoice from the same supplier. If you owe $8,000 on an open invoice and hold a $1,200 credit, you remit $6,800 and reference both the invoice number and the credit memo number on the payment. This clears both transactions in one step.
The alternative is to hold the credit as a reserve when no current invoice exists or when the credit exceeds any single outstanding balance. It rolls forward and offsets the next invoice that comes in. This is common with volume rebates that arrive as lump-sum credits once a year. Either way, every application should link the credit memo number directly to the invoice it offsets. That linkage creates the audit trail your accountants and external auditors will need during reconciliation.
Requesting a Credit When the Supplier Doesn’t Offer One
Credits don’t always arrive automatically. When your invoice review reveals a discrepancy, or when goods arrive damaged and you want compensation, you usually have to initiate the process. Most companies do this by issuing a debit memo to the supplier: a formal request that states the amount, the reason, and references the original invoice or purchase order number.
Speed helps. Suppliers are far more cooperative when you raise issues within days of delivery rather than months later. Document the problem thoroughly with photographs of damaged goods, screenshots of pricing discrepancies between the PO and invoice, or inspection reports from your receiving team. The more evidence attached, the faster the credit memo comes back. Some companies set internal deadlines, requiring discrepancy reports within five business days of receipt, specifically because aging claims become harder to resolve and easier for suppliers to dispute.
Year-End Review of Open Credits
Unapplied vendor credits show up as negative balances within Accounts Payable, which can confuse anyone reading the financials if the amounts are material. At year-end, review every open credit and decide whether it belongs in AP or needs reclassification.
A credit you reasonably expect to use against an upcoming purchase from the same vendor can stay in AP. A credit you’re unlikely to use, perhaps because you’ve stopped ordering from that supplier, may need to be reclassified as a receivable (the vendor effectively owes you money) or written off against the original expense or inventory account. Leaving stale credits buried in AP indefinitely creates real legal exposure.
Unclaimed Property Rules for Aged Credits
Every state has unclaimed property laws that apply to dormant financial obligations, and vendor credits are no exception. If a credit balance sits unapplied long enough, your company may be required to report and remit it to the state as unclaimed property. The dormancy period in most states falls between three and five years, though some states exempt certain AP credit balances entirely. Most states have no minimum dollar threshold for reporting, so even small credits can trigger an obligation.
Your AP team needs a process for periodically reviewing open vendor credits, attempting to apply or resolve them, and flagging any approaching the dormancy window. Companies that ignore this face penalties for late reporting, and state unclaimed property audits have become increasingly aggressive. A quarterly review of aging vendor credits prevents a much larger compliance headache.
Internal Controls Against Credit Fraud
Vendor credits are a known fraud vector. The basic scheme: an employee with too much access creates a fictitious credit, applies it against a real invoice, and pockets the payment that should have gone to the supplier. Or they inflate a legitimate credit and skim the difference. These schemes thrive where one person handles the entire AP cycle from vendor setup through payment.
The core defense is segregation of duties. Separate at least these three functions across different people:
- Credit memo entry. One person receives and records the supplier’s credit memo in the system.
- Verification and approval. A second person confirms the credit is legitimate by matching it to a return authorization, pricing agreement, or other supporting documentation.
- Payment processing. A third person applies the credit to an invoice and executes the payment.
Beyond segregation, regular vendor reconciliation acts as a detective control. Periodically compare your AP ledger for each supplier against that supplier’s own statement of your account. When the two don’t match, including any unexplained credits, investigate before the next payment goes out. Supporting documentation such as the original purchase order, receiving report, and return shipping records should back up every credit memo. If the paperwork trail breaks down at any point, that credit shouldn’t be applied until someone resolves the gap.
