Card threshold allows you to set a dollar limit to determine the payment options allowed. Any payment totaling over the specified dollar amount will not allow your customer to pay by credit card for that transaction. Instead, they will only have the option to pay by ACH (e-check).
By accepting more ACH payments, this will reduce your processing costs by avoiding interchange fees.
To enable the card threshold option, navigate go to your Settings page, then Payment Types, Credit Card.
On the Status tab enter the Card Threshold amount and click Save.
*Note: Leaving a blank value means you will accept credit card payments regardless of the amount.
