Preserving records: Electronic cash register records

Electronic Cash Registers (ECR) and Electronic Point of sale equipment (EPOS) are considered to be computers with a constant memory capable of providing a considerable amount of information on their audit and journal rolls, electronic journals and summary reports (Z and periodic ZZ).

Audit and journal records show each transaction and all corrections as they have taken place, and they are thus seen as vital records in testing the credibility of accounting information shown on the resulting summary reports. This consideration may influence the preservation period you allow.

You can exercise discretion in allowing concessions for till rolls and electronic journals. Full till rolls should be kept for 6 years, or a minimum 4 years where a concession is requested. Where “Z” prints are taken these should be kept for the full 6 years, or as long a period as is practical. All Z reports should be consecutively numbered, dated and timed (a capability of all ECR/EPOS equipment).
