Hi Raam,
I did an extensive research on payment gateways with subscription capabilities. The problem we have here in Europe is that all of your provided gateways are not suitable for EU based countries (except UK).
For example,
Paypal Pro: not working in EU (only UK)
Paypal Standard: stupid 20% rule which basically prohibits membership upgrades and payment method is only credit card
AliPay: only China
Authorize.Net: only USA
ccBill: only USA
Google Checkout: not working in EU (only UK)
ClickBank: only in US Dollar, acts as reseller (not everyone wants to have that)
Therefore, there is not one acceptable solution for Europe (not including UK in this case). You should really consider to create a payment gateway for EU based payment provider.
For example Skrill/Moneybookers – they have 29 million current members and growing. It should be fairly easy for you guys to implement this.
Link to their API doc
A second big European payment provider with subscription capabilities is Ogone.
I know you working on a improvement of your payment API but you should keep in mind that you are loosing out with potential European customers.
If I compare you with the Magic Members Plugin, they already support Moneybookers and Ogone. I already purchased your s2member Pro but I have to consider to switch over to Magic Members because of this.
I read a lot of German online marketer forums and comments and they all prefer s2member or Digital Access Pass as their number one WordPress membership plugin. But a lot of them also mention the problem with the lack of European payment gateways in s2member.
I don’t mind spending money for a working solution. But I think it is also in your interest to get more customers from Europe.
Please let Jason know about this issue.
Maybe we can work something out in the near future.
Thanks
Robert
