Z Report and Fiscal Compliance

Z Report and Fiscal Compliance

Z report and fiscal compliance are critically important operations for restaurant businesses to fulfil their legal obligations. In Turkey, all businesses using a cash register are required to take a Z report at the end of the day and these reports are binding for fiscal audit purposes.

What is a Z Report?

A Z report is a fiscal document containing a summary of all sales transactions carried out through the cash register during the day. The report includes total sales amount, total VAT, breakdown by cash and credit card, total number of receipts and the number of voided transactions. When a Z report is taken, the daily counters of the cash register are reset and a new fiscal day begins.

Automatic Z Report

The system automatically initiates the Z report process during end-of-day operations. At the designated time or upon the closure of the last shift, the system sends a command to the certified cash register (OKC) and the Z report is taken. The report is automatically saved to the system and stored in the digital archive. A Z report can also be taken manually but this operation must be performed by authorised staff.

Certified Cash Register (OKC) Integration

Certified cash register integration ensures data flow between the POS system and the cash register. Every time a check is closed, the sales information is automatically transmitted to the certified cash register and a receipt is printed. The fiscal memory on the certified cash register records all transactions in an unalterable manner. The amounts between the system and the certified cash register are compared at the end of each day and a warning is generated if there is a discrepancy.

Immutable Fiscal Log Records

Immutable fiscal log records ensure that all financial transactions are recorded in an irreversible manner. Every sale, void, refund and discount transaction is written to the log together with a timestamp, staff information and transaction details. No deletion or modification can be made to these records. During audits, these logs are used to prove the original transaction history.

Fiscal Reports

Fiscal reports support the tax return preparation process. Monthly VAT summary, daily revenue report, void and refund summary and payment method distribution reports are automatically generated. These reports are presented in a format that can be transferred to accounting software.

Audit Mode

Audit mode enables tax inspectors to review fiscal records with limited system access. In this mode, only reporting and log viewing are possible; no data changes can be made. Audit mode access is opened and closed by the manager, and all access activities are separately logged.
