We have an invoice in qbs It was paid but now qbs is showing a payment due and a negative amount on the payment received there shouldn't be a negative amount for pymt

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.

1. Go to Gear Icon ⚙, then underneath Tools, select Audit Log.
2. Select Filter.
3. Use the fields on the Filter panel to choose the appropriate Dates, Users, and Events. (In this situation, choose Transactions).
4. 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.
