It shows the data your software cash registers already sent to the ДПС fiscal server: the list of registers, Z-reports for each one, a period summary and every receipt, filterable by date and time. Any receipt can be opened as a register tape or followed through to the tax authority's site.

In two steps, like the tax cabinet. First you attach the key file and enter its password — we check that the key is valid and show you its owner. Then you sign in. ProstoCheck creates no separate logins or passwords: the key is your access.

No. The service is read-only: it does not fiscalise receipts, does not open or close shifts, and changes or deletes nothing. Every settlement operation stays in your ПРРО.

The qualified electronic signature (КЕП) you already use for your ПРРО and the tax cabinet — from any accredited provider.

If the register was working offline, receipts appear once the ПРРО has transmitted them to ДПС. We show exactly what is already on the fiscal server, and mark such receipts separately.

ProstoCheck is currently completely free, for any number of registers.
