Upwork - how to correctly hand over the work and demand payment?

Question

Freelance

Hello. I just completed my first order and since I'm new to upwork, I don't know if I can be deceived or not.
In general, the question is - how to hand over the work and deservedly receive money, and after what words of the customer should you be wary of his intentions? Thank you.

Answer 1

You need to ask the client to reserve funds for you if this is a fixed payment

But there are nuances here too .

Answer 2

Well, just tell the customer that you’ve finished giving the job and he pays, inventing some kind of nonsense here is superfluous, in advance you can’t insure yourself against anything more than described in the initial upwork help
