WooPayments: Integrated WooCommerce Payments

Woocommerce has been around for years and they can't make a decent payment gateway plugin yet.

Disappointing

I had my doubts at first as well, but I have been working with it for the past 3 months on almost a daily basis and it has won me over. 

I work with it daily.


Had some issues connecting with the wordpress.com account, but support team managed it to fix it.


Great support

Securely accept credit and debit cards on your WooCommerce store. Manage payments without leaving your WordPress dashboard. Only with WooPayments.
