ADESSO

About adesso

With over 11,300 employees and an annual revenue of €1.465 billion in 2025, the adesso Group is one of Germany's largest IT service providers with excellent growth prospects. Across numerous locations in Germany, Europe, and Asia, as well as on-site at client premises, adesso optimizes core business processes through consulting and tailored software development. For standardized requirements, the company also offers its own software products. Driven by the ambition to "bring people and technology together like no other company," adesso places a strong emphasis on innovation and digital transformation — including within its own finance function.

As an internationally operating company, adesso faces the challenge of managing a large number of bank accounts, coordinating cross-border payment processes, and maintaining full visibility over financial transactions, liquidity positions, and guarantees.

Challenges before Nomentia: fragmented system landscape, manual processes, lack of cash visibility

Before Nomentia, adesso operated in a heavily fragmented system landscape: multiple e-banking portals, siloed platforms, manual spreadsheets, and decentralized workflows. One of the biggest pain points was in day-to-day operations. Payment file approvals were largely handled via email — each payment triggered an extensive back-and-forth emailing that was effectively doubled by the four-eyes principle. This process was cumbersome, time-consuming, and error-prone.

On top of that, financial transaction data was scattered across multiple sources, leaving no clear overview or transparency into liquidity flows. Many process steps relied on Excel spreadsheets to consolidate information — whether for liquidity analysis, reporting, signatory management, or preparing for bank meetings. This lack of transparency had a clear impact on the efficiency and quality of treasury work.

"The biggest pain point for me was the lack of visibility into group-wide liquidity."

Especially given the traditionally limited staffing resources in treasury and the company’s international structure, it became clear that as the business continued to grow, process efficiency had to improve, and the team needed relief from manual tasks. At the same time, a new system was required to enable tailored reporting and analysis at the push of a button, allowing treasury to support management with reliable, data-driven insights.

The solution: treasury digitalization, step by step

In autumn 2024, adesso evaluated six treasury management system providers as part of a scoping pitch. Nomentia stood out primarily for its ease of use, flexibility, and modular architecture.

"What really won us over about Nomentia was how intuitive the solution is, and that we can manage the system ourselves within our own team. If we want to make a change, we don't need to involve internal IT. We can handle it ourselves."

Another key advantage was Nomentia's strong foothold in the DACH region and its understanding of local requirements. "With Nomentia, we clearly felt their experience in the German market and their understanding of what customers really need. From the very first conversation, it was clear: this is solid and well thought through," says Melanie Fengler.

Initially, adesso planned to implement all modules at once, but then decided on a phased approach. The first phase focused on connecting all banks and bank accounts, as well as digitalizing payments, guarantees, and bank account authorization management. The goal was to first create transparency across group-wide liquidity and make operational processes more efficient. Within nine months, 25 banks with around 100 accounts were connected, and the system was successfully implemented. The most time-consuming part was setting up connections to international banks and API interfaces.

"The implementation went smoothly and was well structured. Working with the project team was always constructive and felt like a true partnership.”

Results: clean processes, full transparency, and analysis at the push of a button

Less than six months after go-live, adesso is already seeing clear results:

• Clean payment processes from creation to approval, thanks to customizable access rights, approval workflows, and templates. For example, restrictive payment templates ensure that payments can only be made to predefined beneficiaries.

“You can get really creative with approval workflows in Nomentia. As an admin, it’s exciting to build solutions that perfectly fit our company while still being simple and easy to follow.”

– Matthias Tiedge, Finance Specialist Treasury, adesso

• Strong adoption and enthusiasm for the solution across decentralized teams, thanks to significant time savings.

“Our colleagues are thrilled about the efficiency gains with Nomentia and have described the new payment system as a real game changer.”

• A centralized data foundation with full traceability: all relevant information is available in one system, making processes transparent and collaboration easier, while also significantly improving compliance.

“In the past, I often had to reach out to my team even for small things. Today, I can simply look them up in the TMS. Everything is in one place. Among other things, this also helps me prepare much more effectively for bank meetings.”

• Full group-wide liquidity visibility and flexible analysis down to account level:

“With Nomentia, we have cash flow transparency at the push of a button—including all external and internal loans, as well as factoring and guarantee utilization.”

– Melanie Fengler, Head of Treasury & Finance Digitalization, adesso

• Positive feedback from the CFO and management, thanks to more detailed and reliable liquidity reporting.

Thanks to the phased implementation, adesso was able to first establish a stable foundation and integrate the system into daily operations. Building on this, additional modules can now be rolled out in a targeted way, without pressure.

In the next phase, adesso plans to further expand its focus with Nomentia on cash flow forecasting.

“Thanks to Nomentia’s modular setup, we have a system that grows with our needs.”
