Rejlers Sweden Selects Deltek, Powered by Maconomy ERP, to Drive Efficiency and Growth

Rejlers Sweden, a top-tier engineering consultancy delivering expertise in energy, infrastructure, industry, and technology, has chosen Deltek, the unified, intelligent platform for project-based work, to modernize operations and support its ambitious growth strategy. Deltek Maconomy ERP, deployed in the Deltek Cloud, will power the modernization effort and help Rejlers scale as it continues to grow across the Nordics.

With a strong presence across the Nordics, the company helps clients design and implement sustainable, innovative solutions that shape the future of society. Their multidisciplinary teams work on complex projects that require collaboration, precision, and a commitment to excellence.

Streamlining Collaboration and Financial Performance

As Rejlers Sweden prepares for continued expansion, the company identified the need for a scalable, fit‑for‑purpose ERP solution. The decision to implement Deltek, utilizing its Maconomy ERP application, was driven by several critical requirements:

• Modernization and Scalability: An ERP application that supports Rejlers Sweden's operating model and enables quick integration of acquisitions for faster financial control.
• Clear Principles for Collaboration: A system that enforces inter-business agreements with transparent revenue and margin sharing, ensuring clarity in joint bids and multidisciplinary projects.
• Enhanced Project Accountability: The ability to empower project managers to take full responsibility for financial performance and invoicing, strengthening financial management across all delivery types.
• Streamlined Invoicing Processes: Support for self-billing and client invoicing without errors, reducing administrative overhead and improving efficiency for both clients and subconsultants.

By implementing Maconomy, Rejlers Sweden expects to achieve a more efficient split of roles and responsibilities, clearer expectations for revenue sharing, and stronger financial management—all while accelerating integration of acquisitions and improving collaboration across its business units.

Mikael Häägg, CFO at Rejlers Sweden, commented:
"Selecting Deltek was a strategic decision to modernize our systems and strengthen our operating model. With the Maconomy ERP application, deployed in the Deltek Cloud, we can integrate acquisitions faster, improve invoicing accuracy, and empower our project managers to take full financial ownership—key steps in delivering exceptional value to our clients."
