client is demanding to do work beyond the requirements

[usamasarfraz]

I have fulfil all requirements of client even did extra work but he still demanding to do work beyond the requirements. What I should do?

For escrow:  you can only dispute and go into mediation.

For hourly: you would have a contract where you can bill hours for the additional work.

Is this escrow or hourly?

Usama, I am assuming this is a fixed-price contract.

If the client has asked you do do ANYTHING outside of the originally agreed-upon requirements, then he is violating Upwork TOS by asking you to work for free.

Do not do anything out of scope. Tell the client that you WILL do the next tasks he is asking for, after he releases the current escrow payment and sets up a new contract or milestone for the new work.
