What TSG does
Technology Services Group Ltd (TSG) is a UK-based, privately-held managed IT services provider founded in 2003 and headquartered in Team Valley, Gateshead. The company specialises in implementing and supporting enterprise software from Microsoft (Dynamics 365 Business Central, Dynamics 365 CRM, Power Platform, Azure), Sage (Intacct, 200), and Pegasus (Opera 3), complemented by proprietary offerings including TSG Mosaic (an Electronic Document and Record Management System built on Microsoft 365/SharePoint) and TSG Academy (a customer training platform). TSG holds Microsoft Solutions Partner and Azure Expert MSP designations, ISO 27001/9001/14001 certifications, and Cyber Essentials Plus, alongside the Microsoft Cyber Advisor partner status.
The company organises its services into four pillars: Business Applications (ERP/CRM implementations and ongoing support), TSG Cloud Care (Azure cloud provisioning, migration, and Microsoft 365 management), TSG Cyber Care (cybersecurity services including Microsoft Defender, Microsoft Sentinel, and a Security Operations Centre), and TSG System Care (on-premises IT support). Revenue is generated through a mix of fee-based implementation projects and recurring managed services subscriptions, with Azure consumption-based pricing layered on top for cloud resources. Its go-to-motion is consultative enterprise field sales targeting UK mid-market organisations (100-1,000 employees) that have outgrown entry-level accounting software, with vertical emphasis on education, housing associations, manufacturing, local government, and nonprofits.
TSG serves a distributed customer base of mid-market and public-sector clients — including Torus Group, Royal Grammar School Newcastle, North Tyneside Council, Brady Bags, Grant UK, and Aylesbury Vale Academy — and reports world-class Net Promoter Scores of +86 to +87. The firm employs 251-500 staff (with 160+ accredited technical experts) and has executed two acquisitions in the past 14 months (Dayta Designs, November 2024; Computer Geeks, March 2025), indicating an active roll-up strategy. Ownership is founder/management-controlled with no disclosed external institutional investors.
