There are two options on payment transactions on GNet. GNet requires that you have a credit card on file in order for reservations to flow through. First option is for high volume users, and second option is for customers with less volume. Both options can be found on the GNet dashboard, under "Administration" tab, then "Billing". Once in "Billing" you will see both options, "Add Credit" or "Manage auto pay".

High volume users can go to "Add credit" and select an amount you wish to add to your account. This option requires a minimum of $100.

The "Managed Auto Pay" option requires that you have a valid credit card on file, and nothing is charged until your first reservation. At that time, you will be charged $50 and each time you receive a reservation the appropriate amount (depending on your reservation system) will be deducted from your available credit. When your credit drops to zero, your credit card will be charged $50.
