Colonial has been a satisfied customer of your Spire.PDF dll library for years; having purchased a license in February of 2015.
We use it in a variety of C# applications, both in website Save-As and automated transformative file creation application situations.

Our group was looking for a cost-effective way to add reliable barcode generation to our web application. We tried some free ones that we found to be inaccurate and put our customers at risk.
Spire.Barcode for .Net has proven to pass our test cases as well as come with a free license. Couldn't be happier!

I'm waiting for a confirmation from my superiors to buy the license. But we already finished the tests with the Spire.Doc, and it works perfectly!
We are very excited to start to work with it, because it fixes a lot of bugs that we have using the Microsoft.Office.Interop's dll.
I guess that I'll probably have the confirmation in the begin of the next year.
