How can I increase the cost of an hour in an existing project?

Question

Freelance

Agreed with the client to increase the cost of an hour (we have been working for a year, he is satisfied). But in the profile you can only DECREASE it)))))).
How can I change the hourly rate upwards? Or is it necessary to start a new contract (in this case, it makes no sense, because the percentage of upwork will eat up the increase)?
Thanks

Answer 1

Start a new contract. Upwork percentage won't eat anything, because it is calculated for all contracts of one client in total. Those. if on the first contract you reached a commission of 5 or 10%, then on subsequent contracts it will remain

Answer 2

increases the customer rate
