Hey Team! Let's talk payments for a sec. Do you discuss payment options prior or at the time of completion? I've had an guest I spoke to about just paying by card on the square reader, then when the job was done the "man" of the house said to just send him a invoice and he would transfer. (Took him almost two weeks to pay it) What's your preferred method to avoid any awkwardness? *note I do mobile, I'm part time and don't have a dedicated garage or workspace.
