I already have a Business ID, can I use the service?

Yes. You can start using Truster Pro Light with an existing Business ID too - you don't have to close your current sole proprietorship.

Subscribe in the app and grant the required Suomi.fi mandates so we can handle bookkeeping and taxation. We check that your existing Business ID registrations are in order and help you transition smoothly. We'll keep you informed as the transfer progresses.
