No, that's not possible: you can't sign contracts on Abillio's behalf, and Abillio is not a pass-through intermediary.
As a service provider, you authorize Abillio to invoice on your behalf under the käsundusleping, and Abillio's share is its 5% service fee.
There's an exception for digital work platforms (Fiverr, Upwork, Toptal, 99designs, delivery services). Contact support to learn more.
