About
We are software developers specialising in complex integrations — Microsoft Office Add-Ins, SharePoint Embedded, B2B eCommerce, and back-end ERP and CRM systems.
McKenna Consultants is made up of an expert team of UK-based software developers specialising in custom software development and complex integrations — connecting SaaS applications with back-end ERP and CRM systems, document platforms such as SharePoint Embedded, Office Add-Ins and eCommerce systems. We also have a division devoted to Agile training, coaching and consultancy.
Why Work With Us?
We are a team of expert computer programmers with decades of experience working on complex projects and the difficult integrations that make them succeed.
Complex Systems Integration
We connect SaaS applications with back-end ERP, CRM, CPQ and PIM systems, document stores and payment platforms — turning legacy and modern systems alike into one cohesive, reliable solution.
Microsoft 365 Integration Depth
From SharePoint Embedded and Microsoft Graph to Office Add-Ins for Word, Excel and Outlook, we embed Microsoft 365 deep inside SaaS products — expertise very few companies worldwide can match.
AI-Accelerated Delivery
Our wholly UK-based team uses AI coding tools daily to deliver enterprise-quality software faster and at lower cost, without diluting engineering quality.
Diverse Expertise
We have developed a diverse range of bespoke solutions including Office integrations, systems integrations, B2B eCommerce, cloud solutions, mobile and web apps.

Working with McKenna Consultants on our WOPI integration was a seamless and highly productive experience. Their team brought deep technical expertise and a clear understanding of both the Microsoft ecosystem and hybrid deployment challenges. McKenna's ability to collaborate closely with our in-house developers—particularly around integrating with our existing microservices architecture and aligning with our UX goals—was invaluable. Thanks to their support, we were able to deliver a WOPI implementation that works reliably across both our SaaS and on-premise environments, fully meeting the standards of Microsoft's Cloud Storage Partner Program (CSPP). I would gladly recommend McKenna Consultants to any organisation looking for a serious partner in enterprise-grade Office integration.
