If you've created a credit note for a client or the client has payments that have not been allocated to an invoice, you can apply the credit or payment to any approved, unpaid invoices.
Allocating Credit or Unallocated Payments
To allocate credits or payments follow the steps below:
Click on "Billing" and then click on "Invoices".
Click on the "View" icon next to the invoice that you want to allocate the credits or payments to.
If a payment or credit is available for the customer, you can use either of the following methods to allocate it:
Method 1 - Under the "Amount Due" section, look for the line below the invoice totals section that shows that the customer has unallocated payments or credits available. Click the "Apply to Invoice" link.
Method 2 - While viewing the invoice, click on "Invoice Options" menu in the upper right corner and then click the "Allocate Credit" option.
On the "Allocate Credit & Payments" form enter the amount of money you want to allocate to the invoice from the customer's unallocated credits or payments.
Submit the form.
Automatic Allocation
You can enable our Automatic Allocation Add-on to automatically allocate a client's unallocated payments & credit notes to an invoice when the invoice is approved.
