Success story

Our solutions rely heavily on third-party controls and Add-in Express is easily the best. After installation, you're setup in a matter of minutes with a starting template. From there, the API is very intuitive and easy to follow. Every time we develop a new Office add-in we forget how fast it is to get a prototype version going.

No routine coding – concentrate on your ideas and customers

Add-in Express empowers you with a strong solution architecture and coherent programming model complemented by a combination of .net components, visual designers and deployment tools that will help you avoid a nightmare of monotonous coding and ensure a quick and perfect result. With Add-in Express you forget all routine things such as implementing Extensibility COM interfaces or XML-schemas, working with the registry, creating deployment scenarios, etc. You simply concentrate all your efforts on your ideas and applied code and amaze your customers with a promptly created prototype and subsequent releases. Do not believe? Just read real stories from the developers like you.

True and proven Office version-neutrality

Add-in Express is rendered a true "must have Office tool" by its optimized version-neutral core. Written in C# and based on the .NET Framework, COM interoperability and low-level Windows API, it will make your Office plug-ins commercial-class and industry-leading. Now there's no need to create Office version-specific or application-specific solutions and deployment packages or search for intricate tricks, and then combine all this stuff into one resulting package. One version-neutral and multi-hosted Office plug-in project and one setup project is quite enough to support all applications and all currently available versions and editions of Microsoft Office, from 2000 to 2010, from Outlook to Visio, from Student and Home to Pro and Enterprise Office editions. It is this approach that was chosen by thousands of developers who build their Office add-ins on Add-in Express.

100% compatibility from version to version

Starting from the first release of Add-in Express, we have always complied with the simple rule - a project built on the prior version of Add-in Express should be 100% compatible with the next Add-in Express version at the source code level. This means that upon installing the latest version of Add-in Express, you merely open your project, rebuild it and… that’s it! Due to this rule, you are not restricted in the choice of Visual Studio versions and editions. For example, using VS 2005 Standard (which is not the latest and by far not the most feature-rich version), you can develop add-ins for Office 2000+ including the latest Office 2010. Not really impressed? Just google for Add-in Express references in developer communities.

Time matters!

If you search in the net for Add-in Express references, you will see that developers who had tried other solutions and technologies and finally came to Add-in Express refer to it as a "good time-saver". The point is that Add-in Express was developed initially as a platform for our own add-ins, and now we continue to use it for all our end-user solutions and custom development services. We invest quite a lot of time and resources in Add-in Express development, but it pays off a hundredfold – all our projects based on Add-in Express take us far less time and effort than it would take for any of our competitors. Be sure, Add-in Express will save your time. You undoubtedly deserve to spend it more profitably – develop your ideas and projects and don't squander your time on trifles and routine.

Support service - that's what is more important than anything else

Like all true programmers we are perfectionists and believe that everything we do must be the best on the globe. No compromises! :) We also strive to make our support service such. And we are happy that day after day we get thanks for our help rendered to the same developers like we are. Look through our forums, what our customers say and a personal notice from the head of our support service to see what our support service really is.
