If you have issued a Credit Note to a client, you can use it to adjust the payment of any other invoice for the same client.
Steps to Apply a Credit Note to Another Invoice
Option 1 – Apply from Credit Note Details Page
- Go to Billing → Credit Note.
- Click on the required Credit Note.
- Click the “Apply to Invoice” button (top-right corner).
- In the popup window, choose the Invoice Number from the dropdown list.
- Click OK.
Option 2 – Apply from Credit Note List View
- Go to Billing → Credit Note.
- On the desired credit note, click the 3 vertical dots (action menu).
- Select Apply to Invoice (this option will only appear if the credit note is eligible).
- In the popup window, choose the Invoice Number from the dropdown list.
- Click OK.
Rules to Remember
- You cannot adjust credit across different clients. Only invoices belonging to the same client can be adjusted.
- A single credit note can be applied to multiple invoices, but only up to its total available amount.
- Once a credit note amount is fully used, it cannot be applied to any other invoice.
- Once credit is applied to an invoice, it cannot be reverted.
- If you need to adjust again, a new credit note must be issued (for example, if the invoice is later cancelled).
Example
You have a Credit Note of ₹100 for Client A.
- Client A has Invoice 1 of ₹50 and Invoice 2 of ₹100.
- You can apply ₹50 to Invoice 1 (it becomes fully paid).
- You can then apply the remaining ₹50 to Invoice 2 (it becomes partially paid, ₹50 still outstanding).
- Once the total ₹100 is used, you can’t apply it to any other invoice.
If later Invoice 2 is cancelled, you must issue a new credit note for the remaining ₹50 to adjust it against another invoice.
System Updates Automatically
- Outstanding balance of the selected invoice.
- Client & Project Statements are updated to reflect the adjustment.
