Cash Register Integration in IZI
Cash Register Integration in IZI
Section titled “Cash Register Integration in IZI”IZI automatically generates a receipt for every payment — top-up, direct session charge, or bar sale — and sends it to the connected fiscal printer without any manual action from the admin. The printer issues the fiscal document and forwards a copy to the designated tax authority or fiscal data operator.
This means cashiers never handle receipts manually: open a payment in IZI, confirm it, and the fiscal document is issued in the background.
How the flow works
Section titled “How the flow works”Payment confirmed in IZI → IZI builds receipt data (items, amounts, tax codes) → Sends to fiscal printer via USB or network → Printer issues fiscal receipt → Printer forwards copy to fiscal data operatorWhat gets fiscalized
Section titled “What gets fiscalized”| Operation | Receipt type |
|---|---|
| Customer balance top-up | Income receipt |
| Direct session payment | Income receipt |
| Bar / merchandise sale | Income receipt |
| Refund to customer | Refund receipt |
| Bonus point redemption | Not fiscalized (no cash movement) |
Prerequisites
Section titled “Prerequisites”Before configuring the integration in IZI:
- A registered fiscal printer with a valid fiscal memory module installed
- Active contract with a fiscal data operator (where required by law)
- Printer physically connected to the computer running the IZI Client — via USB or local network
Setting up the connection
Section titled “Setting up the connection”Open Club Settings → Cash Register in IZI CRM.
- Select Connection type: USB or network
- Choose your printer model from the supported list
- Enter the connection parameters (COM port or IP address)
- Click Test connection — IZI sends a test request to the printer
- Save settings
After saving, every payment is fiscalized automatically.
Supported hardware
Section titled “Supported hardware”IZI communicates with fiscal printers via the ATOL driver protocol (KKT driver v10). Verified models include:
- ATOL 91F, 92F, 77F, 55F
- SHTRIKH-M (FRK, FR-K series)
- Other models with ATOL driver support
For hardware not on this list, contact IZI support to arrange compatibility testing before purchase.
Shift close and Z-report reconciliation
Section titled “Shift close and Z-report reconciliation”When you close a shift in IZI, the system generates an IZI shift report — a software-level summary of all transactions.
Separately, print the Z-report from the fiscal printer itself. This is the legally significant document for tax purposes.
The totals in both reports should match. A gap between them signals that either some payments bypassed the printer, or some IZI transactions were not passed for fiscalization.

Section titled “Related pages”Frequently asked questions
Do all clubs need a fiscal receipt printer connected to IZI?
Only if local law requires it. IZI works without a connected receipt printer — payments are recorded in the system regardless. The printer is needed when regulations mandate issuing a fiscal document for each transaction.
What happens if the printer is offline during a payment?
IZI records the transaction internally. Most fiscal printers store pending receipts in their fiscal memory and transmit them to the tax authority once the connection is restored. You can still process payments, but monitor the printer's memory capacity.
Do I need a separate contract with a fiscal data operator?
Yes, where required by law. IZI sends receipt data to the printer; the printer forwards it to the fiscal data operator via a separately configured channel. The contract with the operator is arranged outside of IZI.
Is bonus payment fiscalized?
No. Bonus point redemptions do not involve a cash flow, so no fiscal receipt is generated for them.
Do I need to reconcile the printer's Z-report with IZI's shift report?
Yes. At shift close, compare the totals from the printer's Z-report with the IZI shift report. A discrepancy means some payments were not fiscalized or some IZI operations were not passed to the printer.
