Someone bought an online skype lesson from me, should I click “deliver now” after the lesson or when we start it?
I would sugest right after the lesson or right at the begining. I mean it give you a chance to notifly your buyer directly about you deliver your order, and know that they read them right at the moment. You should tell them something like “now before we start/now as we have finished, I’ll click the deliver button to complete the order. Please rate my service.”
