How online acquiring works for FOPs: Frequently Asked Questions

Can I accept online payments without a cash register (RRO)?
  • In most cases, a cash register (RRO) or software-based cash register (PRRO) is required, even for FOPs on the simplified tax system. However, there are exceptions depending on the type of services, payment methods, and income volume. We assist in evaluating your specific situation and, if necessary, help you connect a PRRO through solutions like CheckBox to ensure legal compliance.
