Dear @smashradioThank you so much for the detailed explanation. Your mean can be clearly understood.
The adjustments he asks me to do are count as relatively tiny adjustments, so I think it might be better not to tell the buyer anything about this subject. unless I realize he is asking for more complex revisions. Hope my experience would help other sellers to be more clear in their gigs description, especially when they are giving details about their revisions service. Regards, Mohammadreza
