Any users who have a recurring payment or an open tab set up will effectively have a "card on file". This allows gym owners to quickly and easily charge users for apparel, supplements, gear, etc without requiring additional authorization or interaction by the user.
Cash, Check, and "Other" (Square or other billing systems) payments can also be tracked in WODTogether. Use the same process as above, just select Cash, Check, or Other for the Method.
Please note that there is no recurring option for offline payments, each must be entered manually!
