A purchase credit memo in Microsoft Dynamics 365 Business Central is a document that reverses all or part of a posted purchase invoice, reducing the amount you owe a vendor. It is used when you return goods, receive a price correction, or get a rebate after the original invoice has been posted.
What Is a Purchase Credit Memo?
In Business Central, a purchase credit memo is the purchasing counterpart to a sales credit memo. It records a negative purchase transaction, meaning it decreases your accounts payable balance and your inventory or expense accounts. The system creates a posted credit memo and a corresponding vendor ledger entry, which can be applied to the original invoice or left unapplied for future use.
Unlike simply editing the original invoice, a credit memo preserves the audit trail. You can see the original purchase, the reversal, and the net amount owed. This is essential for accurate financial reporting and for reconciling vendor statements.
How to Create a Purchase Credit Memo
There are two primary ways to create a purchase credit memo in Business Central:
- Manually: Go to Purchases > Purchase Credit Memos and create a new document. You can fill in the vendor, lines, and quantities manually, or copy lines from a posted invoice.
- From a Posted Invoice: Open the posted purchase invoice, then choose Correct or Create Corrective Credit Memo. The system pre-fills the credit memo with the invoice lines, which you can adjust before posting.
When you post the credit memo, Business Central updates the vendor balance, inventory quantities (if items are returned), and general ledger accounts. You can then apply the credit memo to the original invoice or leave it as an open credit.
Key Fields and Settings
Understanding a few important fields will help you use credit memos correctly:
- Vendor No.: Must match the vendor on the original invoice if you want to apply the credit.
- Posting Date: Determines the financial period in which the credit is recorded. Make sure it falls in the correct period for your reports.
- Document Date: Usually the date of the credit memo itself.
- Apply-to Document No.: Use the Apply Entries action to link the credit to a specific invoice. This is crucial for accurate aging and payment matching.
- Item Charges: If the original invoice included freight or other charges, you can include them on the credit memo lines or as a separate line with the appropriate charge code.
Common Scenarios and Examples
Here are typical situations where a purchase credit memo is used:
- Returning defective goods: You received 100 units, 10 were damaged, and you return them. You create a credit memo for 10 units at the original unit cost.
- Price correction after invoice: The vendor agreed to a lower price retroactively. You create a credit memo for the difference (e.g., $1.00 per unit on 50 units = $50.00).
- Rebate or volume discount: The vendor offers a rebate after you exceed a purchase threshold. You create a credit memo for the rebate amount, often without inventory lines.
For example, suppose you received an invoice for $1,000 for raw materials. Later, you return $200 worth. You create a purchase credit memo for $200, post it, and apply it to the original invoice. The vendor balance now shows $800 due.
Posting and Applying the Credit Memo
When you post a purchase credit memo, Business Central creates the following entries:
- A vendor ledger entry with a negative amount.
- General ledger entries that reverse the original expense or inventory posting.
- Item ledger entries if you are returning items to inventory.
After posting, you can apply the credit memo to the original invoice. Go to the vendor ledger entries, select the credit memo and the invoice, and choose Apply. This prevents the credit from sitting as an open balance and ensures the invoice is marked as fully or partially paid.
If you don’t apply the credit, it remains as a vendor open balance, which you can later apply to a different invoice or request a refund.
Differences from Purchase Invoice Correction
Business Central also offers a Correct function on posted invoices. That creates a corrective credit memo and a new corrected invoice in one step. The original invoice remains in history, but the net effect is zero. In contrast, a standalone credit memo only reverses the amount without creating a new invoice. Use the Correct action when you want to reissue the invoice with changed lines; use a credit memo when you simply want to reduce the payable.
Reporting and Financial Impact
Purchase credit memos appear in vendor statements and in the Vendor Aging report as negative amounts. They reduce your total purchases for the period, which affects your cost of goods sold and profit. In VAT-registered countries, the credit memo also reverses the input VAT that was originally claimed. Ensure your VAT posting groups are set up correctly so the credit memo uses the same VAT percentage as the original invoice.

Frequently Asked Questions
Can I create a purchase credit memo without a posted invoice?
Yes, you can create a manual credit memo from scratch. However, it is easier and more accurate to copy from the original posted invoice, especially if you need to reference line details.
What happens if I post a credit memo with a wrong posting date?
The credit will be recorded in the wrong financial period, which can distort your monthly reports. You can correct it by posting a reversing credit memo (a credit for the credit) and then posting the correct one. Always double-check the posting date before posting.
How do I apply a credit memo to an invoice?
Go to the vendor’s ledger entries, select the credit memo and the invoice, then use the Apply Entries action. You can also apply it from the invoice by selecting Apply Entries and choosing the credit memo.
Can I partially apply a credit memo?
Yes, you can apply only part of the credit memo to an invoice, leaving the rest unapplied. This is useful when the credit covers multiple invoices or when you want to keep a small credit for future use.
Does a purchase credit memo affect inventory?
If the credit memo includes item lines, it will increase inventory quantities (since you are returning goods). If it only contains general ledger lines (like a rebate), inventory is not affected.
Summary
A purchase credit memo is a standard tool in Business Central for handling vendor returns and price adjustments. By creating, posting, and applying it correctly, you keep your accounts payable accurate and maintain a clear audit trail. Always verify the posting date, apply the credit to the right invoice, and review the VAT implications.
