Canceling and Regenerating Invoices

From WHMCS Documentation

Sometimes, you may wish to cancel an unpaid invoice and later need to regenerate an invoice covering the same time period for the service.

Cancel an invoice

To cancel the original invoice:

  1. Navigate to Billing > Invoices.
  2. Click on the invoice.
  3. Click Marked Cancelled.

Regenerate the invoice

To regenerate the invoice for the same period:

  1. Navigate to the Products/Services tab of the client's profile.
  2. Click on the service.
  3. Move the Next Due Date value forward by one day. This will ensure that the value in the database resets to match the next due date when using continuous invoicing.
  4. Click Save Changes.
  5. Navigate to Summary tab of the client's profile.
  6. Click Generate Due Invoices.
