The Z Balance report totals give you a total of all transactions done across all acquirers. The Banking report totals give you the total for each acquirer. You should try to add up all the individual totals across all acquirers on the Banking to try to reconcile with the Z Balance total. The current session totals on the Banking shows all transactions for that session - if you perform the Z Balance and Banking at the same time every trading day this should match the totals on the Z Balance. If you still cannot match the totals you should contact the terminal Helpdesk. Please ensure that you have all relevant reports with you when you call. It is possible that you will be asked for the proceeding day’s reports as well.
