The Clover (First Data) integration completely integrates payment forms into your checkout — payments are made directly on your website, giving merchants maximum control over the experience, and ensuring customers never leave your site to pay.

From within WooCommerce, merchants and employees can:

Process refunds / voids for transactions
Capture prior authorized transactions from the edit order screen
Force charges for orders with only virtual items instead of authorizing them
Automatically capture transactions when order status changes to a paid status
Accept Major Credit Cards / Debit Cards – Visa®, MasterCard®, American Express®, Discover®, Diner’s, JCB

Customers also have advanced usage and management on your storefront:

Customers can securely save their payment method to their account for easier checkout
Use an payment form at checkout with retina icons
Use a mobile-friendly checkout with numerical inputs for card type and security code
See detailed decline messages at checkout instead of generic errors
Customers never leave your site during checkout

USA ePay provides extensive compatibility with WooCommerce and other extensions:

Full Support for Constellation by Kestrel
Full Support for WooCommerce Subscriptions
Full Support for WooCommerce Pre-Orders
