Advantages
Save time and cost of the product development. The writing of own classes to support PDF, RTF and DOCX formats in C# requires a lot of days of hard work and takes approx 300 000 C# code lines. Document .Net will save a lot of my time and I'll need only to add the reference to "SautinSoft.Document.dll" and write 5-7 C# code lines.

The one product provides me by set of API to create, load, parse, convert, modify documents in various formats at once: DOCX, RTF, PDF, Text.

Because of this is absolutely standalone .NET library, my clients don't need to have Adobe Acrobat, MS Word or other software.
