Circumvention is paying or being paid outside Upwork for work with a client or freelancer first met through Upwork, which the Terms of Service forbid during the non-circumvention period unless the conversion fee has been paid.
The rule exists because Upwork earns on payments, not introductions. Once a client and a freelancer or agency have been put in touch through the site, whether by a proposal, an invitation or a message, every payment between them for the non-circumvention period, 24 months from that first contact, must go through Upwork. Agreeing to invoice directly, taking a bank transfer or a card payment, sharing contact details in order to move the job, or asking for a "small part" to be paid elsewhere all count, and so does a client's offer to do so, since the rule binds both sides. The only sanctioned way out is the conversion fee, paid by the client to take the relationship off the platform early, or waiting out the period.
The consequences fall on the account: a report or a pattern in messages can lead to an account hold and then a suspension, and work paid outside Upwork has no payment protection, no escrow and no dispute process. For an agency, a member who takes a client off the platform exposes the agency account.
What is not circumvention: a client bringing a freelancer they already knew onto Upwork and paying through it, a freelancer working with a client they met elsewhere entirely, or talking by phone or video once a contract exists. The test is where the relationship started and where the money goes, not where the conversation happens.
