Starting in June, the hiring client will choose to pay either a 2.75% fee per payment or a flat $25 per month (for eligible clients).
The freelancer will now pay a sliding scale fee based on lifetime billings for each client. The fee starts at 20% for the first $500 per client, goes down to 10% for the next $9,500, and will be 5% thereafter.
