Editing your invoice status is a breeze, and I'm here to help you. Let’s go to the Invoice page to change it.

Here’s how:

2. From the list, choose the entry you’re working on.
3. Then, click the View drop-down under the Action column to select Mark as unpaid.

Unfortunately the "unpaid" option is not in the drop down.

the only drop down options are:

delete

In QuickBooks Self-Employed, we're unable to mark an invoice as unpaid. I've got a workaround you can perform instead. You can duplicate the invoice and delete the paid one.

Here's how to duplicate the invoice:

1. Select Invoices from the left pane.
2. Locate the invoice.
3. Click the drop-down menu under the Action column.
4. Select Duplicate.
5. Click on Save.

Once done, let's delete the other paid invoice:

1. Select Invoices from the left pane.
2. Locate the invoice.
3. Click the drop-down menu under the Action column.
4. Select Delete.
5. Select Yes.

Also, I'm adding an article that'll help you manually add sales tax to invoices: Manually track sales tax in QuickBooks Self-Employed.

Please feel free to leave a comment. Have a great day!

Why is this process so unnecessarily complicated? Please fix this issue. There should just be a "delete payment" option. Duplicating an invoice and all this nonsense, it needs to be fixed. Can this be updated ASAP to reflect this need that so many of us have?

Allow me to provide some clarification on your concern and help you from there, jbcruz.

For now, the option to get the pay button to show on the invoices is unavailable in QuickBooks Self-Employed. 

I want you to know that your voice matters and I appreciate that you took a moment of your time to provide us with additional feedback. I can see how adding this option on your invoices could help your business. We'll take this as a product suggestion. After all, updates and changes to QuickBooks are largely the results of feedback provided by users.

1. Go to the Gear icon and select Feedback.
2. Enter your product suggestions in the pop-up. Then, select Next to submit it.

Don't duplicate the invoice, just go into the payment and "clear payment". It will remove the "paid" amount, and the invoice will mark itself as unpaid.
