I'm creating invoices as normal, I've been paid, when I click the blue record payment section it says no invoice is due, create credit. My unpaid invoices disappear??

Help has arrived, upanddowngaraged. I'm here to ensure you're able to mark your invoice as paid.

I've replicated your concern and was able to receive a payment on my invoices. It seems like you're experiencing a browser-related issue. The stored cache can affect the performance of QuickBooks, which can cause unexpected behavior.

For us to resolve this, I'd suggest logging in to your QuickBooks Online account via a private window. This doesn't use the existing cache files, which makes it a good place to determine if there's an issue with the browser. 

Here are the keyboard shortcuts: 

• Safari: Command + Shift + N 
• Google Chrome: CTRL + Shift + N
• Mozilla Firefox or Microsoft Edge: CTRL + Shift + P 

Once signed in, record the invoice payment. If you're able to do let's clear the browser's cache. This removes its stored cache to improve the performance of the program.

If private browsing doesn't work, I'd recommend using different supported browsers. They'll provide you the best and most secure experience with QuickBooks.

Once done recording the payments, you can now deposit the amount. I encourage browsing these articles for your reference on how to do that.

Please come back and keep us posted on your progress in receiving the payments of your invoices. It's my priority to ensure your transactions are recorded accurately.
