Why is an unpaid invoice showing up as partially paid?I've converted from estimate to invoice and its telling me it's partially paid even though its not.

I know a way to verify why your invoice is marked as partially paid in QuickBooks Online (QBO), davie.

If you have set your QBO Company file to automatically apply credits, this could be the cause of why your invoice was partially paid. When the option is switched on, available credit from a particular customer applies to the oldest open invoice or the next one.

We can verify that one by going to the invoice transaction and seeing the payments applied to it:

1. Go to the Sales menu and select the Invoice tab.
2. Locate the transaction you are referring to and tap this to see Invoice activity.
3. From there, you can see the payment details and where it was coming from.

If the option is turned on, we can switch this off by visiting this article and refer to Step 1: Turn on or turn off Automatically apply credits: Create and apply credit memos or delayed credits in QuickBooks Online.

Once you’re certain that the payment linked to it isn’t correct, then, we can delete it. I’ll show you how:

1. From the Invoice activity, tap the Edit invoice.
2. In the Invoice window, click the payment link under the Payment Status.
3. Tap the Date to route you to the Receive Payment window.
4. Scroll down to the bottom and click Clear Payment. Then, Save and close.

After that, you can mark this paid once you receive the actual payment for this one. I have an article here where you can refer to keep your records accurate: Record invoice payments in QuickBooks Online.
