Should I continue to endure a low price payer?

[iamnico]

I have been working with this user for years now. Once in a while, I do think about how he pays me and how much effort I exert doing his requests with unlimited revision, and he gets kind of mad when I fail to satisfy what he wants for this “free” work.

I really get stressed out buy this client of mine. I once opened this issue up to him, I thought he would change but eventually came back to his past approached. We are in good terms, I just don’t like what’s happening now.

What could you suggest I should do?

I think it is important to always give the best service you can. As you have been doing this for years with this buyer he probably does not appreciate it any more and believes he is the one who is doing you a favor!
I suggest bringing it up with him, perhaps increasing your fees or another way of making the arrangement better for you. If he is not happy to make a new arrangement, maybe you should let him go. He will then have to find a new seller and we all know that it is not easy to find good, reliable sellers. You might lose him as a customer, so think carefully about it, but he might also come back to you and agree to the new terms as he has had a bad experience with another seller or has not found anyone as good as you.
