i think, there should be one more option between ACCEPT AND REJECT
you get an order. you work hard for 3 days. and deliver but you missed some work (suppose 10%) because you are not familiar with any specific extention or software.
if u not not expert, even in revisions u will give same result.
then buyer has two options (1) accept your work which has small deficiency
or (2) reject it
in case of accept buyer will ask once again to other person to complete short area of work.
if he rejects, it will lost you. you did 3 days hard work and will not get a single penny.
in this case there should be option that he dont fully reject but give the seller some percentage of budget. so that seller don’t remain empty hands.
(note: its my personal opinion. i don’t know about the existing rules. if any person know about this please tell me to update my knowledge). thanks
