We have extensive experience of developing Outlook, Word, Excel and even PowerPoint Add-Ins.

What Is WOPI?

WOPI is a complex protocol which allows you to embed Word, Excel and PowerPoint inside your core application. The URL in the address bar of the web browser is your and Microsoft supply the web client for you. The WOPI protocol is complex and difficult to implement for beginners. We have worked on over 20 WOPI implementations which makes us the world-leading consultancy in this field.

Our clients are in the fields of:

  • Legal software
  • Auditing software
  • Work and Workflow software
  • Education software

You can find case studies and testimonials linked below.

WOPI improves your SaaS solution by allowing users to edit documents in place inside your application. Your user no longer have to download files to desktop, edit them and then reupload them (and fix any conflicts that then arise!). WOPI takes care of all of this and includes out-of-the-box co-authoring capabilities.

Not only can we assist with the technical side of implementing WOPI, we can also help you navigate the Microsoft validation process that you must go through to get your WOPI implementation live.

Microsoft Office Add-Ins

Whereas WOPI embeds Microsoft Office inside your application, Add-Ins reverse the situation and embed your application inside Microsoft Office! You have probably seen Add-Ins in the past that appear in the Microsoft Office ribbon and open in a task pane, exposing key features of your SaaS solutions.

These means that your users can seamlessly access features of your SaaS platform from directly inside the familiar environment of Microsoft Office.

We have created Add-Ins for the clients for the following purposes:

  • Outlook Add-Ins to continuously  sync conversations into CRM and workflow platforms
  • Excel Add-Ins to track audits and collate evidence
  • Contract and legal document editing software to insert clauses and terms into documents
  • and more...

We can even assist with the complexity of accessing and using the Microsoft Graph API to unlock more powerful features for Outlook Add-Ins.

How Our Service Works

Most of our clients come to us because they have a need for a complex WOPI / Add-In implementation that they cannot resource (either because of time or skills) from within their existing teams.

We provide the primary software development team for the creation of the the WOPI and / or Add-In implementation.

We use your source control systems, your build and deployment systems, your documentation systems and we work closely with your existing team to make sure that the Add-In correctly integrates into your existing eco-system.

Naturally, all of the code and intellectual property is yours! Most of our clients take over some or all of the maintenance of the software once it is complete, perhaps returning to us when they don't have capacity to add new features themselves.
