I have clients that often ask for a minor change due to an error on their part and are willing to pay. I would love to create a custom order amount for 2 or 3 to be fair, especially when it is a $5 gig in the first place. Charging a full $5 just doesn’t feel fair. Wish tips could do the same, as far as I know the smallest tip is $5 too.
Now I often do custom order for odd amounts like $82 etc, it’s just those smaller gigs that the $5 limits seem to hurt.
