For stores on Cartum, two PRRO integrations are available — Checkbox and Vchasno.Kasa. If you decide to change the PRRO integration enabled on the site, pay attention to a few points that are important for switching.
In general, the operating principles of all PRRO services are similar, because the fiscal receipt form and the list of data required to create it are defined by law. However, there are certain differences in the formats in which different systems accept order data, which is why each of them requires its own settings.
Please note: you cannot enable two PRRO services at the same time.
Preparing to switch
Before switching Checkbox/Vchasno.Kasa, complete the fiscalization that you planned to perform with the previous provider.
Data about receipts that have already been fiscalized in a particular service remains in the order, so it is impossible to accidentally fiscalize the same receipt again.
Automatic fiscalization
If auto fiscalization is enabled on the site, you will not be able to disable the PRRO until all requests for receipt fiscalization in the service have been processed. After you finish working with receipts in one system, you will be able to connect and configure data transfer with automatic fiscalization in another service.
How to properly switch to another PRRO integration
Tax rates
When changing the PRRO service on the site, don’t forget to specify the tax rates for Products for each service.
Payment types
For each payment, the receipt must include data about the payment type. These settings are available in Payment methods.
Fiscalization permission
Permissions to fiscalize receipts are retained when changing the PRRO service. If you need to change store Users who have permission to fiscalize, keep this in mind.
