If we’ve applied workarounds there could be invoices or bills that were paid and allocated in the source system that we haven’t been able to convert as allocated in Xero. The payment should have been converted so the overall customer or supplier balances should be correct. Allocating the invoices or bills will correct the list of individual outstanding items so they agree to your source.


Xero Central provides instructions on allocating these:


Apply a customer’s credit to an invoice – Xero Central

Apply a supplier’s credit to a bill – Xero Central
