Automatic every day
Shift opening, sales, returns, and the end-of-day Z-report are all fiscalized automatically — the cashier works as usual.
Integration · PRRO
Fiscalization via Checkbox — right from the POS
Connect the Checkbox.ua software PRRO to Posimos and fiscalize receipts directly from the POS terminal — no separate fiscal registrar required. Each receipt is signed and sent to the Tax Service automatically.
Why Checkbox
No separate PRRO app
The Posimos POS becomes the PRRO frontend: everything happens on one screen.
Multiple registers
Support for multiple registers (e.g. "Bar" and "Kitchen") within a single venue.
What you need to connect
Checkbox.ua account
A registered account at my.checkbox.ua with a configured register.
License key
A separate license key for each register in your account.
Cashier PIN
A PIN code for cashier authentication at the register.
VAT tax groups
Groups with codes 1–8 configured in your Checkbox account.
Receipt printer
A receipt printer connected to the terminal.
Internet at the register
A stable network connection — fiscalization works online only.
What Posimos handles for you
Shift open and close
Automatically opens and closes the fiscal shift, including cash deposits.
Sales and returns
Fiscalizes sales, returns, and voids with no extra steps.
X- and Z-reports
X-report on demand and Z-report automatically at shift close.
Cash-in and cash-out
Cash deposits and withdrawals are recorded in the fiscal shift.
Discounts and service fees
Discounts, bonuses, and service fees are calculated with exact rounding.
Fiscal receipt printing
Prints a text or graphic receipt with a QR code and fiscal signature.
What to keep in mind
Online only
An internet connection is required for fiscalization. A sale still completes — the receipt is queued and printed once connectivity is restored; the register is never blocked.
Shift must be open
The fiscal shift must be open — it opens automatically.
Fiscal orders only
Only orders marked as fiscal are fiscalized.
Z-report on close
The Z-report is generated when the shift is closed at the end of the day.
