How to associate payment to an invoice?

Manually creating a payment document in the Back Office is important for several reasons: correcting a sale document where the payment was accidentally deleted, completing a sale made manually in the Back Office, fixing an incorrect payment in a transaction, or settling unpaid invoices. It's also essential that the payment document is linked to an invoice.

Steps:

1. ​Navigate to the Back Office and select the "Sales" tab at the top.
    
2. Then, click on "Invoices."
    
3. Locate the invoice you wish to add a payment to, and click it to open the sales document.
    
4. Scroll down to the bottom, where you'll see a plus sign labeled "NEW" on the right; click it.
    
5. This will bring up a page where you can create a payment document. Ensure the correct customer name and invoice number are selected. Enter the payment amount, then click the "Save" button located in the upper right corner
   
   
    
6. After saving, click the back button in the upper right corner to return to the sales invoice document, where you’ll see the payment reflected at the bottom of the page.​
