How does fixed price work on Elance?

Question

Freelance

Hello.
I'm new to Elance and don't quite understand some of the work. Let's say I received an order with a fixed price, for example $20. I did everything that was required of me, received the money to the account (I see it in the Manage-Transactions-Available Balance), but in the process of work, the customer wanted me to continue working on the project until the release and he is ready to pay me more. But the problem is that the work is Fixed Price, that is, I have already worked out my $ 20. What do I need to do next? Don't change the job status to "Completed" and create new "Milestones" every day and send new invoices that cost more than the starting price of $20?
Thank you.

Answer 1

Firstly, you can discuss with the customer and switch to an hourly rate (maybe this is possible under the current contract)
Secondly, Elance has the ability to send bonuses to the performer. So a couple of weeks ago, a client sent me money as a bonus, in addition to the hourly payment.

Answer 2

Is it possible to create new invoices, milestones and additionally indicate the cost of new services there?
It’s just that I have a problem that I don’t do everything on a PC, that is, I test applications on a mobile device mainly, and I only do reports on a PC. Running a time tracker that will send empty screenshots to the customer may not be exactly what you need.
