Apply credit memos to invoices and debit memos


Apply credit memos to invoices and debit memos

After you have posted a credit memo, you can fully or partially apply the credit memo to one or more invoices and debit memos. You can apply credit memos to invoices or debit memos only if you have the user permission. See Billing Roles for more information.


Through the billing settings configuration, you can configure a default application rule to determine how the system allocates credit memos applications to invoices and debit memos. Zuora uses the specified application rule to automatically allocate the credit at the item level if you have not specified item-level application amounts explicitly.

When a credit memo is applied, the total number of invoices and debit memos that the credit memo will apply to must be less than or equal to 1,000.

If the Proration application rule is used, when applying credit memos, each credit memo item will be split into parts and these parts will be applied to the debit memo items in proportion. To prevent reaching the system limit for handling application items, ensure that the following quantity must be less than or equal to 15,000:

(number of invoice items + number of debit memo items) * number of credit memo items

Otherwise, the First In First Out rule will be used instead of the Proration rule.


To apply a credit memo through the Zuora REST API,  see PUT Apply Credit Memo.

To apply a credit memo through the Zuora UI, complete the following steps:

  1. Navigate to Billing > Credit and Debit Memos in the navigation section.
  2. On the Credit and Debit Memos page, find the target credit memo in the Credit Memos tab.
  3. Locate the row of the target credit memo and click Apply on the right side of the row. The "Apply this credit memo" page opens.
  4. In the Effective Date field, specify when the application will take effect.
  5. Select the invoices and debit memos to which you want to apply.
  6. For each invoice and debit memo, you can apply the credit memo at item level:
    1. Click the plus icon (+) next to the document. The items of the invoice or debit memo are displayed. 
    2. Select the items to which you want to apply the credit memo. 
    3. Specify the amount you want to pay for each item in the Credit Applied column. The Balance column shows the total amount you must pay for that item. 
  7. Click Apply.

A table is then displayed at the bottom of this memo page. This table records detailed information about the invoices and debit memos that the memo is applied to.
