PaySimple for WooCommerce lets a service business that bills through PaySimple take card payments in its WooCommerce store on the same merchant account, so online orders land beside its invoices and recurring billing.

Card details never reach your server

The card form is PaySimpleJS. PaySimple draws it in its own frame on your payment step, so the card number, expiry, CVV and postcode go straight to PaySimple. Your server only receives a payment token that works once, which keeps your PCI scope small.

Charged from your server

The plugin collects the payment for the order total with your API credentials and sends the order number and a description along. The order is marked paid only when PaySimple answers that the payment was authorised for the order's own amount. A declined card shows PaySimple's reason and the form reloads for another try. If the card network has not answered yet, the order waits on hold instead of being shipped or charged twice.

Void or refund, chosen for you

Press Refund on the order for the full amount. PaySimple voids a payment before its daily cut-off and refunds it once it has settled; the plugin reads the payment and uses the right one.

Good to know

You need your own PaySimple account with API 4.0 credentials (PaySimple support issues them, and sandbox ones for testing), a store in US dollars and HTTPS. PaySimple's API returns a payment as a whole, so a part refund cannot be sent from the order screen. ACH, saved cards, recurring schedules and 3D Secure are not included.
