How do i change my old invoices to 30 days net after a migration? I have changed the terms but my old invoices still shows overdue which it it is not.

Hello, jackie@sjlabels..

I'll share the steps on how you can modify the terms.

For now, you will need to edit the invoices one at a time. Here's how you can update the payment terms on each transactions:

1. Go to Sales on the left panel.
2. Click the Invoices tab.
3. Find the invoice that shows overdue and select the Edit link.
4. From the Terms drop-down, choose the payment term you've setup for this customer.
5. Hit Save and close.

On the other hand, you can go to the Apps menu on the left panel then look for a third-party application that can modify the invoices in bulk.
