What does the sole proprietorship service cost?

Truster Pro Light is priced per invoicing: a 3.99% service fee on the amount you invoice, plus Truster Turva at 2.50% of the invoice amount.

Opening the sole proprietorship is free (normally 140€) provided the subscription stays active for 6 months from registration and you invoice through Truster during that time. Payment Monitor is available for 1.99€.
