Step 3 of the Donation Website Wizard is Payment.
Choose whether you would like to absorb the processing fee, pass it on to donors, or split it. If you choose to absorb it, you can also allow donors to opt to cover the fee.
Then select a Payment Account. It must be a 501(c)3 account. If you haven't set one up yet, you can follow the click here link to create one.
If you'd prefer, you can use Set Up Later to invite someone else from your organization to set up the payment account. Test Mode will allow you to keep customizing the donation website before you set up payments.
The Vantiv Dynamic Descriptor fields allow you to customize the way donations appear on a credit card statement. The text you enter in the box is the text that shows up next to a donation on a credit card or bank statement.
