So, I have two contracts open with similar naming.
But last Sunday I fulfill my hours and made the payment hour request to the wrong client.
Is it possible to revert this situation? I already tried to talk with the support but I couldn't find the support chat anymore. Also, I have the freelancer plus plan, I don't know if it could help me with this question.
Please check the "You logged time on the wrong contract" section of this help article to see how a situation like this could be handled. Since it is not possible to edit the Work Diary once the work week has ended you can refund the client that was invoiced by accident and add manual time to the correct contract. You can also ask your client to pay you a bonus for the hours worked last week.
