I saw people complaining about buyers misusing the revision options to get more works done from sellers ! If you are good at communication It’s a easy problem which can be solved.If you are done with your promised work that’s all.
there is a option in fiverr and a condition in fiverr.
if they are asking to do more something than We promised We are eligible to request for extra.I always trust fiverr tos and nothing going wrong with me.If I feel like I should help the buyer I am not asking for extras.If I feel like this going too far I am asking for extra.this is how I work this is my formula.If you are good at something never do it for free. Trust your common sense trust Fiverr.
