# My customer balance seems off

> Diagnose why a customer outstanding balance in Upflow does not match the sum of invoices, including unapplied payments, credits or sync delays.

The outstanding amount displayed does not correspond to the sum of invoices? Does it show an unapplied balance?

This might be due to:

* an unlinked credit note
* an unlinked refund
* an unlinked payment
* a synchronization issue
* etc.

On your Customer's page, check:

* their open invoices and remaining amounts
* the payments list and unapplied amounts
* the credit notes and unapplied amounts
