Platform fees scale with every payment
Upwork charges freelancers a variable service fee of up to 15% per contract and clients pay a marketplace fee on top of every payment, plus a one-time contract initiation fee for each new hire. Because these fees are percentages, they grow with the size of the contract.
A time tracker, on the other hand, is a fixed cost. On WebWork, a team member costs $3.99 per month whether they bill $500 or $5,000.
