Vchasno.Kasa (PRRO)

ERPJS integration with the Vchasno.Kasa software-based fiscal cash register (PRRO): sale receipt fiscalization, cashier mode (POS), shifts with a service Z-report, cash in/out and receipt import from the cabinet.

Three connection modes to the PRRO are supported; they are chosen with two checkboxes in the account card — "Use Public Fiscal API" and "Use cloud proxy" (both at once are not allowed):

  • public fiscal API — "Use Public Fiscal API" ticked (recommended; only it supports receipt import);
  • cloud proxy (DM proxy) — "Use cloud proxy" ticked;
  • direct mode — both cleared, requests go straight to the address in the "Host" field (usually a device on the local network).

A detailed step-by-step guide with screenshots is in the Instructions → Vchasno.Kasa section.
