Here’s how you can set a due date for each customer — either while adding a new one or updating an existing one:

Step 1: From your dashboard, click on Customer / Vendor.

Step 2: To add a new customer, “Add New Customer.”
OR, to update an existing one, just find their name and click on “Edit” option.

Step 3: Scroll to Additional Details, enter the number of Due Days (e.g., 15 for 15 days), and click “Save”.

Note: From now on, any invoice for that customer will automatically pick up the due date you’ve set.
