Yes. Big River allows you to prompt your donors to pay your transaction fees, or to automatically add them to a transaction.
On the Checkout Form tab, you will see the selector for "Fees":
There are three options in the dropdown:
- Do not offer or charge a fee
- Prompt to add a fee to the total
- Automatically add a fee to the total
The first option will not put any transaction fee cost on the form. The second will put a prompt on the form for the donor to opt into paying the transaction fee.
If the donor checks this box, the transaction fee calculated from the subtotal of selected items will appear:
The third option" Automatically add a fee to the total" does this calculation automatically.
