neb, firstly have you checked your records to see if the amount was processed thru your account? If you don't have records contact your bank to see if you can get a statement for the date in question. Secondly if the amount has not gone thru and you received money for the service & goods from your customer IMO you should pay the supplier, if this customer was the ATO they get 7 years to call in a debt. Goodluck with this, hope its a small amount.
