Once the payment is made before the set date, the status of your invoice will change to Partially Paid. You can go ahead and add an **Adjustment** to the invoice manually for the remainder and save it. To add an adjustment: * Go to the **Invoices module** under **Sales** on the left sidebar * Open the specific invoice. * Click the **Edit** icon. * Scroll down and add the remaining amount as an **Adjustment.** ![Make adjustments to an invoice.](/books/kb/images/invoices/adjustment.png) * Click **Save.** * In the pop-up that appears, enter a reason for editing the invoice that has already been sent and click **Save.** The status of the invoice will change to Paid.
