How about using Woocommerce for the checkout process for a GeoDirectory payment. The rationale for this would be to keep all user transaction history in one location and to use the same gateway and payment options for all transactions between platforms.
Scenario is this:
I sign-up for my listing in GeoDirectory, fill in all the required information, payment step takes me to a Woocommmerce checkout page to complete my transaction.
Have you had anyone do this and is there an existing solution that is available?
