If you do not accept payment types, for example checks or gift cards, you can make payment types (even the default payment type options) inactive in Springboard Retail.
How to make a payment type inactive
Go to 'Settings' in the top navigation bar and then 'Payment Types' in the left navigation bar.
Click on the name of the payment type you want to deactivate.
Slide the 'Active' button to 'Disabled'.
Disabled payment types will no longer show up in your 'add payment' tender options in the POS.
Note: Under 'Settings' > 'Financial', you must have the 'use financial system' box checked to click into and edit 'check' and 'cash' payment types.
