the order is about 15days long, and near to the delivery time client want some extra works which will take 6-10days extra. He will pay for that. But the thing is he want to confirm the order after completing those extra works.
So my question is after the order time how many days for revision will cause no harm? If I will send him delivery and he will give revision request after delivery time then can I deliver modified work after 6-8days?
