"[Encore Systems .NET class] libraries have some additional features beyond what the PayPal .NET SDK offers,
including an improved integration with Visual Studio. ... For those of you who don't develop with .NET,
Encore has also released some slick testing/demo utilities for working with each of our API operations,
that provide you an interface to enter in request variables, trigger an API call, and see the API responses
and any corresponding errors. ... A great testing utility that all PayPal developers can leverage!"
"We use the Encore Systems components at Wellhire.com and were so pleased with the ease of integration,
we converted our other site over (ITIL Prime
)- in a matter of days.
I absolutely recommend these components, especially for the price, and [Encore's] exceptional support of them."
"I purchased Encore Systems' .NET SOAP version of the PayPal DLL and I am extremely pleased.
[Encore's] support of this product allowed me to create the PayPal interface for our client in less
than a day. I would highly recommend this product for any developer that doesn't want to suffer
through the learning curve of the PayPal transaction set."

"I was able to get the payment system setup on my web site in about an hour with the use of the
Encore Systems dll. For the price of the component it was well worth it. I'm very happy with the results."
"I highly recommend this. After struggling with all of the options in the PayPal API, Encore's pre-built
routines had me passing successful transactions within hours. The demo software is fully functional with
the sandbox, and by using it and the testing routines I was able to build and test my application before
committing to buy. At $39 for a single site, or $99 for a developer license, it's a bargain compared to
the hours I would have spent with the standard API. Their support was also top notch when I had a question."
: "We here at
have been building a custom paypal solution for one of our clients. We came
across a couple of road blocks and went to the forum seeking help. This is where we found Scott
(Encore Systems). He helped us out, but more importantly showed us the API Testing interface that [Encore]
had designed and built. This system has been invaluable to us here at Taylor Digital. The API Testing
Interface saved us hours of debugging and development time. “It is the best thing ever! It’s like a
sandbox for the sandbox, only this one actually gives you the info you need to debug with” - says one
of our employee’s here. We appreciate [Encore’s] time spent building such an elaborate and useful
utility. If you ever need something done right, I’d look to Encore Systems for paypal integration!"

"Our company had to start supporting an eCommerce site which offers PayPal as a payment type. We needed to
automate our nightly process to capture funds after orders shipped. The PayPal API documentation provided
examples but none really helped in our VB.NET/ASP.NET environment. Found mention of the Encore Systems
.NET Class Library via a Google search. The online demo was very impressive. Getting the demo library
working was easy and we saw the benefit of the library immediately. Sent a support request to [Encore] with
questions about creating a new VB.NET program using the demo template. [They] responded quickly with helpful
suggestions. ... We purchased the library the next day which includes additional templates. Now we have a
VB.NET app to settle transactions and an ASP.NET page to allow customer service to support PayPal orders.
I definitely recommend this library."
"Hi, I highly recommend using the testing tools from EncoreSystems. They are a great resource for every
PayPal Developer. The UI is easy to understand and you can see the request / responses that are great for
debugging / improving your understanding. I was going through the manual for their class library and it
is pretty well written as well. Good job."
