Hi,
Quickly skimming over I haven't really found an answer for this - do you charge additional costs to modify an existing premium theme according to the purchaser's requests ?
If yes, what is the rate?
Regards
It depends on what are the requests. Could be a very simple one like changing color which is not a problem since most of the costumers do it themselves (they just ask for guidance).
If it's something more complex could be, but normally we do not charge any additional fees.
