We are 4 persons who collaborated on a job. Can the salary be shared and the client receive one invoice?
Yes. After you create the invoice, there is a step called Share the invoice. There you can add other persons Firmify account number (located in the Profile-view), and the creator of the invoice can control how much of the gross amount that will go to each one of you. If your colleague does not have a Firmify account, please ask them to create one, and ask them for their Firmify account number.
