Applying a cash payment to a customer invoice

Greetings, @stacie_.

Let's isolate this unexpected behavior for possible data damage by running the verify and rebuild tool.

Here's how to Verify:

1. Go to Window then choose Close All.
2. Select File then choose Utilities.
3. Click Verify Data.
4. If QuickBooks detected no problems with your data," no further action is needed.
5. A specific error message, there may already be an article for it. Try searching for it in our QuickBooks Desktop support site for specific instructions.

If there is data damage in the file, run the Rebuild Data Utilities to correct the problem. 

1. Go to File.
2. Hover over Utilities, then select Rebuild Data.
3. You'll receive a message to back up your company file, hit OK. This will ensure that you have a secured copy of your company file.
4. Choose a place to save your backup.
5. Once the backup is finished, the Rebuild Data utility will start.
6. When you receive the message, "Rebuild has completed," then press OK.

You can check this article for more detailed information on verifying and rebuild data in QuickBooks Desktop. Verify and Rebuild Data in QuickBooks Desktop.

Once completed, you can try receiving invoice payments again.

Let me know if you have any other questions by adding a comment below. I'll get back to you as quickly as possible.

I ran the "Verify Data" and "Rebuild", but unfortunately this did not fix my problem. It is still not saving the payment as a "Cash" payment.

Thanks for getting back to us, @stacie_.

I appreciate you for performing the steps given by my colleague above. I've got another resolution to keep you going this time.

First, make sure to update QuickBooks Desktop to its latest release to have the latest features and fixes.

Once done, you'll have to run QuickBooks Tool Hub to help fix the issue you're getting. For the best experience, I recommend using the Tool Hub on Windows 10, 64-bit. Below are the steps to accomplish this:

1. Close QuickBooks, and then download the most recent version (1.4.0.0) of the QuickBooks Tool Hub. 
2. Save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). 
3. Open the file you downloaded (QuickBooksToolHub.exe), and then follow the on-screen instructions to install and agree to the terms and conditions.
4. Double-click the icon on your Windows desktop to open the tool hub.

Then, select Company File issues option under Step 2 this article: Run QuickBooks Tool Hub.

If the same thing happens, you can do a clean install to refresh the program.

You'll want to customize your invoices to personalize them and have the info you need.

Also, you can run the Open Invoices report to know all the unpaid invoices and when they're due. This can help you keep track of them, and receive payments once ready. Here's how:

1. Go to the Reports menu, and then choose Reports Center.
2. Select the Customers and Receivables tab, and then look for the Open Invoices report.
3. Click the arrow icon to run the report.

I'm around to lend a hand if you have more QuickBooks concerns. Take care and stay safe always.
