I'm here to help you link your customer's payment to their outstanding transaction, flrs4ia.cw2.
If the payment is not associated with the outstanding entry, the system is unlikely to update the transaction with the correct remaining amount. For this reason, you'll need to record that payment to connect it to the invoice and balance your accounts.
Here's how:
Click on the +New button at the left navigation panel.
If the accurate remaining balance still won't display after you've performed the steps above, a cache-related issue may be causing this. To rule this out, you can use a private or incognito window. Here are the shortcut keys:
For Mozilla Firefox browser: Ctrl + Shift + P
For Google Chrome browser: Ctrl + Shift + N
For Safari browser: Command + Shift + N
After that, log in to your QuickBooks Online (QBO) account and redo your task. If it works, clear your browser's cache to remove the webpage data causing the issue. If a private browser doesn't work, use other installed supported browsers as an alternative.
