Hello @yana-ringo! Happy to see you reaching out to us in the Community. I'm wondering, did you record that payment as a deposit or check?
If you did, that could explain why it is not showing up as paid or as a negative balance. You can find out how you recorded that payment by using the Audit log: Use the audit log in QuickBooks Online.
- Go to Gear Icon ⚙, then underneath Tools, select Audit Log.
- Select Filter.
- Use the fields on the Filter panel to choose the appropriate Dates, Users, and Events. (In this situation, choose Transactions).
- Select Apply.
The best way to record that payment is through the Receive Payment option within the Invoice itself. Don't worry if you recorded it in a different way. Here's an article on how to connect that check or deposit to that invoice: How to link a deposit to an invoice.
Feel free to reach back out to me here in the Community so we can continue to look at this together.
