Vendor Credit: What It Is & How to Apply It

Your client returns $1,847 worth of equipment to a vendor. The vendor sends a credit memo. Where does that $1,847 go?

If you said "Other Income," you're not alone. It's the most common vendor credit miscoding out there. But it's wrong, and it quietly inflates the P&L every time it happens.

Vendor credits don't belong in income. They reduce either the original expense or the AP balance, depending on whether the original bill has been paid. Here's how to get it right.

What is a vendor credit?

A vendor credit is a credit memo issued by a vendor that reduces what your business owes them. It typically comes from a return, an overbilling, or a billing dispute. In QuickBooks Online, a vendor credit posts as a negative entry in accounts payable, reducing your open vendor balance. It sits in AP until you apply it against a future bill or receive a cash refund. The credit does NOT increase income; it reduces an expense or reduces AP. Common dollar amounts range from a few dollars (shipping overcharge) to thousands (equipment return or disputed invoice).

Key Takeaways

Vendor credit reduces AP, not income. Booking it to Other Income overstates profit by the full credit amount
Unapplied credits can expire. Many vendor terms allow write-off after 6 to 24 months, and the credit can disappear without notice
Cash refund vs. credit-on-account post differently. A refund hits your bank feed; a credit-on-account stays in AP until applied
In QBO, use "Vendor Credit" not "Deposit" or a journal entry, or the vendor record breaks
The original bill matters. If the bill was already paid, the credit usually reduces the next bill in the same expense category; if unpaid, apply it directly to the open bill

What Vendor Credit Actually Is

A vendor credit is a formal memo from a vendor that reduces the balance you owe them. It shows up in accounts payable as a negative balance against that vendor. Think of it as the mirror image of a bill: a bill increases AP, a vendor credit decreases it.

In the accounting glossary, vendor credit sits in the same bucket as other AP adjustments. It's not a revenue event. It's a reduction in what you owe, or a reduction in the cost you incurred.

Three common triggers: a return ($1,847 credit for defective inventory), an overbilling ($150 credit because the vendor charged $500 for a $350 service), or a dispute resolved with a credit memo instead of a rewritten invoice.

Each scenario ends the same way: a vendor credit in your AP subledger.

How vendor credit posts in double-entry

When you enter a vendor credit in QBO: AP decreases (the vendor owes you less) and the original expense account decreases (cost goes down). A $1,847 equipment return credit reduces Repairs & Maintenance by $1,847 AND reduces what you owe the vendor by $1,847. No income account involved.

Read the accounts payable primer to see how the AP subledger tracks this at the vendor level.

How Bookkeepers Apply Vendor Credit in QBO

The entry path in QBO is straightforward if you use the right workflow.

Step 1: Enter the vendor credit

"+ New" → "Vendor Credit." Fill in:

Vendor name (must match the vendor on the original bill exactly)
Date (use the credit memo date from the vendor, not today)
Category (same expense account as the original bill)
Amount

Save. QBO posts the credit to AP as a negative amount. The vendor's balance drops by the credit amount.

Step 2: Apply the credit to an open bill

"+ New" → "Pay Bills." Select the vendor. You'll see open bills AND the credit memo listed. Check the credit memo and the bill you want to offset. Save. The credit reduces the payment due.

If the credit is larger than the bill, you apply the credit to the bill and the remaining credit balance stays in AP until you get another bill from that vendor, or until you request a cash refund.

Step 3: Cash refund scenario

If the vendor refunds cash instead of issuing a credit to apply later, the workflow is different. The cash hits your bank feed. Match it to the vendor credit you already entered. That ties out the AP subledger and deposits the money to the right bank account. Do NOT enter the refund as a deposit with a category of "Other Income."

What about the accounts payable aging report?

A vendor credit shows up in AP aging as a negative line for that vendor. Negative amounts are unapplied credits waiting to be applied. A credit sitting at 60+ days means it hasn't been applied to a bill in over two months. That's when to call the vendor.

Common Miscoding Pitfalls

Booking vendor credit as income

This is the biggest one. Someone receives a $1,847 credit memo from the vendor and posts it to "Other Income" or "Miscellaneous Income." The reasoning usually sounds like "money coming back to us." But it's not income. It's a reduction in an expense that was already recorded.

The result: the P&L shows $1,847 more income than it should. The balance sheet shows a vendor with a negative AP balance that doesn't match any credit. The tax return potentially includes income that shouldn't be there.

Fix: delete the income entry, enter a Vendor Credit, apply it to a bill or leave it in AP.

Credit sits unapplied for 12+ months

Vendor credits don't chase you down. If you enter the credit but never apply it, it sits in AP aging as a negative balance. Vendors typically allow themselves to write off credit memos after 6 to 24 months. When they do, the credit disappears on their side but stays on your books as a negative AP balance that can never be applied.

Check AP aging for credits older than 90 days. Apply the credit, get a refund, or write it off (debit AP, credit the original expense account).

Treating cash refund and credit-on-account the same way

These post differently and require different workflows.

A credit-on-account stays in AP as a negative balance until you apply it to a future bill. The money never hits your bank account.

A cash refund hits your bank account. You'll see a deposit in the bank feed. If you already entered the Vendor Credit in QBO, match the deposit to the credit. If you didn't enter the Vendor Credit first, you can match the deposit to a "Vendor Credit" at the time of reconciliation.

If you enter both a Vendor Credit AND a separate income line for the same refund, you've double-counted. One cancels the other on the AP side, but the income entry stays on the P&L overstating revenue.

The check: after applying, the vendor's transaction history should show one credit memo and one payment or applied amount. Not a credit memo plus a deposit to income.

How Growthy Handles Vendor Credits

Vendor credits are a categorization pattern problem. Bookkeepers see a negative or credit-style transaction come through and the system has to know it goes to AP, not income.

Growthy recognizes the pattern from prior vendor interactions. If you've categorized a credit memo from this vendor before, Growthy categorizes the next one the same way. You review and approve it; it doesn't guess on its own. Built by a CPA firm partner with 18 years of reconciling AP subledgers, so the pattern library reflects what actually goes wrong in real client books.

If a credit comes through as an ambiguous transaction (a refund with no vendor name), Growthy flags it for your review instead of guessing. You tell it once where it goes. It remembers.

Frequently Asked Questions

Is a vendor credit the same as a vendor refund?

No. A vendor credit is a credit memo that sits in AP until applied. A vendor refund is cash returned to you. A refund can stem from a credit memo, but the two events post differently in QBO. Credit stays in AP; cash refund hits the bank account.

Can I apply one vendor credit to multiple bills?

Yes. In QBO Pay Bills, you can split the credit across multiple bills from the same vendor. The remaining credit balance stays open in AP for the next bill.

What account should vendor credit affect?

Same expense account as the original bill. If the original bill was posted to Office Supplies, the vendor credit reduces Office Supplies. For current-period credits, always match the original account.

What happens if a vendor credit expires before I apply it?

Contact the vendor first. If they've already written it off, write it off on your side: debit AP (reducing the negative balance) and credit the original expense account. Don't leave a stale negative AP balance; it distorts aging and confuses year-end review.

Vendor credits create outsized P&L problems when miscoded. Get the workflow right once and it becomes automatic. Check AP aging monthly for unapplied credits before they expire.
