Recently I accepted a contract for a small ($130.00) fixed-price job. BEFORE I accepted the contract, I let the client know that he would need to (1) fund the whole amount through escrow and (2) designate half ($65.00) to be released immediately as an upfront payment. (I didn't know what else to call it...) The client did both of these things. I got notification from Upwork of the whole escrow and the (upfront milestone) $65.00 being available as soon as I requested it, with my needing to say that the task that triggered the $65.00 payment had been completed.
I called the task "upfront payment as agreed by client" and requested the money. It was released.
Don't know if this is the "right" way to handle this, but it seems with the rules and it worked.
Hope it works for you.
Cheers, Susan Seawolf Hayes
I Dont care if Upwork take away the fixed price option! I will aways ask the client for upfront payment on fixed price jobs! Period!
Upworks again taking away features we like and giving us what we dont want! Or just taking them away!
