After discussing terms for a contract, I submitted a revised proposal to my prospective client. But he can't figure out how to access the revised proposal to accept and fund it. I'm a freelancer so I can't see what his screen looks like. And there doesn't seem to be any way to contact someone from Upwork who can walk him through that. How can I get this done?
If you proposed different terms the client will see the updated bid when they view your proposal. If you have already agreed on terms in Messages, the client can go ahead and hire you. They can do it straight from the Messages:
Once they press "Hire Freelancer" button, they will create an offer and send it to you. Once you accept that offer, you'll have a contract with the client.
Feel free to share this help article with the client to help them with the process.
