Billing in RevSend works by first adding a card on file by navigating to Admin (on the left side panel), then to Account Balance. There you can add your card and deposit funds to your users.
Your monthly subscription fee, if there is any, will be charged to the card on file and will not affect the funds added to each user.
Depositing funds into RevSend is not required to start purchasing gifts. We recommend depositing funds because it reduces the number of charges on your billing statement, and it allows you to control the amount of funds each of your users can spend.
To allow a user to spend without funds deposited, check Enable Fallback Payment by their name in the budgets table. This will allow the user to swipe the card on file in an unrestricted manner.
