How do I change an invoices status when I still send invoices by post as our customers don't have email addresses?

Hi @crazygirl007,

Allow me to share some insights on this question.

You can record invoices as normal. No need to worry if they're showing up as Not sent since you send invoices by post anyways. When you receive the actual payment, that's when you mark it as paid.

Leave me a comment below if you have any other questions.

Would be interested in finding out how to do this for QB self-employed as the invoice won't display unless it's to be sent by email.

Thank you for joining the thread, @ElaineB2.

In QuickBooks Self-Employed (QBSE), we can send the invoices to your email to change the status.

Also, once the invoices mark as paid in QuickBooks Self-Employed (QBSE), they'll default to today's date. Please know that QBSE only offers a simplified invoicing feature. Thus, the ability to modify invoice payments, such as the date, isn't available.

Just in case you need help categorizing your transactions in the future, you can check out this article for more guidance: Categorize transactions in QuickBooks Self-Employed.
