Connect your Stripe or ProPay accounts from the Payment Processors tab in Preferences to enable processing card payments and record the associated fees.
You can process card payments in Boulevard by selecting Stripe or ProPay, then connecting your accounts. Select Other to record the fees if you use a different payment processor. The amounts in the Fees section are used to calculate applicable fees and automatically post them to expenses using the selected Expense Category.

Options button on the main toolbar, select 
Payment Processors (or from the Edit menu, select Preferences, then the Payment Processors tab).
