No, the two plugins, despite having the same name, are not the same. The one on WooThemes site was released a couple of hours earlier than ours, and it is maintained and supported exclusively by them.
We don't sell single site or multi-site licences. If you purchase our plugins, you are allowed to use it on as many sites as you like.
Support for all Authipay modes
Authipay can work in three modes, named PayOnly, PayPlus and FullPay. Aelia Authipay Gateway allows you to choose which mode you would like to enable on your site.
Fully compatible with Currency Switcher
We are the authors of thr acclaimed Currency Switcher plugin, and we test our products to make sure that they work well together. Other plugins may work as well, but we don't test them personally.
Aelia Authipay Gateway is cheaper than the WooThemes one. This is due to the fact that we are a small business, and that, by selling directly to our customers, we don't have to pay the high commissions charged by large marketplaces.
