If you had a conversion, it is quite common for some customer balances to be incomplete. This is because not all kinds of data are converted from all other systems into The Edge. We strongly recommend that you take a complete balance report from your old system just prior to conversion, and from The Edge right after conversion, and identify which balances need to be adjusted.
For converted pending service and layaway transactions, it is possible for a discrepancy to arise because the conversion process cannot always tell deposits from payments in full. Sometimes pending transactions are seen as complete; they should be voided and re-entered.
