It is completely free to access and use the Collab Market, for both Content Creators and Music Makers. It is also completely free to send out, receive and accept collab proposals. Music Makers do pay their collaborator for collabs, but negotiate the fee themselves directly with the Content Creator. Fixed fees are paid directly by the Music Maker to the Content Creator using PayPal. Collabhouse does not charge a commission or fee on any collab fees paid.
