For ПРРО owners

Your registers' receipts and Z-reports — in one place

ProstoCheck shows the data your software cash registers already sent to the tax authority's fiscal server: the list of registers, Z-reports, period totals and every receipt. You sign in with the same key you use for your ПРРО.

FISCAL RECEIPT

Features

What ДПС already has — in a form you can read

Your register data is not moved anywhere: we only read it from the fiscal server and lay it out so you can take it in at a glance.

All your registers

Every ПРРО registered to your tax number: address, state, whether a shift is open, and when the last Z-report arrived.

A Z-report you can actually read

Shift totals laid out plainly: sales, returns, receipt count, the cash / card split and tax by rate.

Period report

Several Z-reports as one total — a week, a month or any range you pick, with day-by-day dynamics. Something the tax cabinet does not offer.

Receipts with filters

Every settlement document of a register. Filter by date, time and type — sale, return or service.

Receipt visualisation

A receipt in the familiar register-tape layout: line items, quantity, price, VAT, payment method and fiscal numbers.

One click to the tax cabinet

A button opens the very same receipt on the tax authority's site, so you can check what we show against the source.

How it works

Two steps to sign in — and your data is on screen

Exactly like the tax cabinet: first we check the key, then you sign in.

  1. 1

    Attach your key

    The same КЕП you use for your ПРРО. First we confirm the key can be read and show you its owner.

  2. 2

    Sign in

    The second step is the sign-in itself, as in the tax cabinet. ProstoCheck creates no logins or passwords of its own.

  3. 3

    Look at your data

    Registers load automatically. From there: Z-reports, period reports and receipts for any range.

ProstoCheck is read-only: it does not fiscalise receipts, does not open or close shifts, and changes nothing in your registers.

Look at your registers right now

No sign-up needed — all it takes is the key you already use for your ПРРО.
