Can I add 'pas due' invoice information on invoice form?

It's great to have you here in the Community, Jacky. Let me share information about sending an invoice with its due date and invoice number.

To begin with, please know that when invoicing your clients, the email will include the Invoice Due Date and Invoice Number.

Moving forward, on the Note to Customer field, you can add any message you want to include in your invoice, such as how many days their invoice is past due.

When creating an invoice, please follow the screenshot below:


Once done, here's an example of what your customer will receive: 








Additionally, if you need to record an invoice payment, please refer to this article: Record invoice payments in QuickBooks Online.

Let me know if you have further invoice concerns or have any QuickBooks-related queries. Keep safe.
