I recently sent out a marketing campaign to customers offering 15% off their next purchase. Our business model currently requires customers to pay in advance ( we approve or deny and their card is charged) prior to services rendered. Based on my reading about the coupon codes through the seller community, it appears as those coupon codes are currently only set up to be used as customers are paying in person. I see no link within the admin dashboard of the website in which I can apply a code, only through the mobile app. Because payment is required in advance, how am I to allow customers to redeem these codes where there is no link or dropdown from the approve/deny screen when I take their payments from the admin dashboard of the website?? Please help, thank you.
