Behind this rapid transition is a complex operation. Old systems that no longer connected, growing pressure on compliance, and the desire to support employees better. The choice for Mysolution brought not only a technological change, but also peace in the organization: one platform, tailored to the Dutch market, that is ready for daily practice and for what is yet to come.
Adecco's old system was once developed internally, says Femke Hellemons, Country Head Adecco Netherlands, who began her career with the staffing organization 25 years ago. "Back then we made the first step from card box to automation. That was top of the notch back then and the foundation for many years."
"The system no longer met the requirements for the staffing profession in 2025. The profession doesn't change, but the way you do it does."

But the technology grew into a patchwork: two different front office systems, eight mid office systems and dozens of interfaces. "The old system eventually worked against us and actually hindered the employee journey. A system just has to do what it's supposed to do. As soon as it drops below that, frustration sets in. The system no longer met the requirements for the staffing profession in 2025. The profession doesn't change, but the way you do it does. Automation has to facilitate that."
"The staffing world is rapidly becoming digitized. Where candidates used to walk in naturally, almost all interaction now takes place online, for example via video calls, WhatsApp and portals."
"Anything where humans don't create added value , you have to digitize so that we can maximize our impact on candidate and client."

And then there is the increasingly tightening labor market, the increase in laws and regulations, and the need for compliance. "Automation is not optional. It has to depend as little as possible on people, precisely to avoid mistakes. And at the same time, you have to remain productive in a competitive market. Everything where humans don't create added value, you have to digitize, so we can maximize our impact on candidate and client."
"The result: one reliable source of information. Mysolution is an end-to-end system. The front office can follow the process all the way through to payroll."

To stay compliant and streamline processes, Adecco decided to implement a single front- and mid-office system. Geert Halsberghe, Regional Head IT & Digital at The Adecco Group, was closely involved in the choice of Mysolution.
"Mysolution's strength lies in its standardization. The front office runs on Salesforce, while the midoffice solution is based on Microsoft technology. Together they form one integrated system. You can think of it as two boxes that fit together perfectly. Mysolution provides the link between them."
Sounds simple, but it wasn't. "We involved everyone - from sales to midoffice. Everyone except the cleaning crew," laughs Halsberghe. "The implementation took only ten months. Never experienced that before. The key was focus. Everyone was behind this project from day one."
One of the biggest challenges: data migration. "You can't just transfer data. If you input junk, junk comes out. But it worked."
The result: one reliable source of information. "Mysolution is an end-to-end system. The front office can follow the process all the way to payroll. The system is based on Salesforce and Microsoft, as well as tailored to Dutch practice: from collective labor agreements to payroll processing. It is in line with our international strategy and complies with national legislation."
"The first payroll via Mysolution went almost flawlessly technically. We had scenarios in mind, of course, but they were hardly necessary," says Halsberghe. "After the first batch, the second and third quickly followed. Flex workers barely noticed the transition. Mysolution's support team remained in place until midnight. Only when everything was running smoothly did they go home."

Hellemons led the project as the person with final responsibility. "We analyzed every process: what are we doing, what can be improved?" From the beginning, Mysolution worked intensively at all levels: steering committee, project management, operations. "You have to be able to switch gears, make decisions, monitor progress. That only works with short lines of communication."
Halsberghe is also complimentary: "Mysolution learned a lot from us, and we from them. Such a large front, office implementation, including portals, is not an everyday occurrence for either party. The project brought the entire organization closer together."

Change often evokes resistance, but at Adecco it remained limited. "Because the old system was causing so much pain, everyone was open to renewal." Six-weekly updates ensured commitment: "Everyone, from interceder to absence manager, knew what was coming and what it meant for their work. Training sessions and demos were organized at all locations to properly prepare employees."
Hellemons finds that younger colleagues in particular pick up the system quickly. "It works intuitively. In the old system you had to memorize codes, that is no longer necessary. A better employee journey leads to less turnover. We want people to feel welcome, enjoy the work and stay with Adecco."
According to Halsberghe, Mysolution forms the basis for further digitalization. "Because our solutions also run on Salesforce, it connects seamlessly. We want to reduce the time between vacancy and placement, give candidates a response faster and support career development."
"And the candidate journey has also improved. Flex workers now manage their affairs independently, from leave to payroll. All the information is in one clear system. As a result, employees don't have to repeat questions, and communication runs much more smoothly," Hellemons concludes.
