Thank you for your post. We are familiar with NSoftware and their E-Integrator solution they offer for payment gateways. However, even though they offer a great product, it would be very difficult to support this in Sitefinity Ecommerce as a bundled product. Our main concerns is payments of any kind are the most critical part of an ecommerce system and because this is a 3rd party product, support can only be from NSoftware and not Telerik. My other concern is the end user license agreement they have for customers who use their software contains text like "not able to compete" with NSoftware, which could cause some issues in the future for Telerik and Sitefinity Ecommerce.
However, we are considering adding to our existing payment provider the methods for a programmer to add in their own payment gateway which could include NSfotware integrator solution. Our current payment provider method is still not fully built out, and we will highly consider looking at the ability of adding NSoftware in our payment provider methods.
Thank you again for your post.
And please continue to provide us suggestions and feedback!
