Hello squammake-gmail.
Nice to see you in the QuickBooks Community! I will be more than happy to help. Here's how:
- Log in to your QBSE account.
- Head to Invoices, then choose the invoice you want to edit.
- Under the Action column, click Edit.
- Select Customize, then go to the Invoice details section.
- Toggle on the Due date and update it manually once it appears on your invoice.
- Either Save it or Send it again to your customer.
Once done, this is how your invoice should look and where you can find the Due date when sending it to a customer:
Please let me know if you were able to make these changes! See you soon.
