I have a client that purchased a punch card for 5+1@90minutes in house service. He wants to use the card for out call. do I credit the balance of the card to an out call rate and bill him the balance due?
I'd have that discussion before going to his house to do the massage. Be sure he understands that an outcall costs more than in-house and that he must pay the difference.
I agree with Laura. You need to talk with him ahead of time and help him realize that the punch card is only for in house. Do you offer a punch card for out calls? maybe you can suggest that and charge him more for the out calls card.
