London, UK – July 2026 – SIS, a Microsoft Solutions Partner for Business Applications and leading implementer of ERP and CRM solutions for the construction industry, is thrilled to announce the successful go-live of OCS Group with the SIS Construct 365 Project Cost Management module from the SIS Construct 365 solution suite for Microsoft Dynamics 365.
OCS Group is a global facilities services business with 120,000 colleagues and 8,000 customers across the UK, Europe, APAC and Middle East regions. With more than 125 years of heritage in the UK and Ireland, OCS Group (www.ocs.com/uk) provides integrated facilities services that help organisations across both public and private sectors to operate safely, efficiently and reliably every day. The company’s teams combine operational expertise, sector knowledge and technology to maintain the spaces and infrastructure their customers rely on.
With an established Microsoft Dynamics 365 Finance and Supply Chain ERP solution already in place at OCS Group, newly acquired businesses are migrated from their incumbent finance system to the group platform. One such business, providing FM Hard Services, was moving from Microsoft Business Central to the group finance system, but needed extensive project cost management functionality that the group platform could not provide.
After discussing their options with Microsoft UK, OCS Group’s transformation project team was introduced to SIS UK. Online demonstrations and discussions confirmed that SIS’s Construct 365 Project Cost Management module could provide the required construction project capabilities.
“By selecting SIS Construct 365 Project Cost Management, OCS Group is building a digital foundation for real-time financial oversight and disciplined execution across their operating segments,” said Mark Kershteyn, Partner at SIS. “Integrating with Microsoft Dynamics 365’s robust platform, our solution empowers OCS Group to achieve greater cost control and operational agility, aligning with their commitment to innovation and excellence.”
Following the successful deployment of C365 PCM, OCS Group’s Hard Services division can streamline budgeting, cost tracking and financial reporting across its delivery teams and customer projects. This module provides advanced tools for managing budgets, change orders, subcontracts and Cost Value Reconciliation (CVR) reports, offering real-time insights to mitigate risks, optimise profitability, and support informed decision-making in dynamic Facilities Management service environments.
The solution’s seamless integration with Dynamics 365 Finance ensures real-time insights and streamlined operations for construction projects.
“We are proud to support OCS Group in their digital transformation with Microsoft Dynamics 365 and SIS Construct 365,” said Andrew Rowney, Director at SIS UK. “Our industry-tailored solution empowers OCS Group to enhance project profitability and operational efficiency, positioning them for sustained success in a competitive landscape.”
