How ACA Group transformed VDAB's district work voucher system (wijk-werkcheques)

VDAB, a public employment service in the government sector, needed to ensure continuity of its district work voucher system after its external provider discontinued the service. ACA Group developed a secure digital platform to manage and distribute electronic district work vouchers, ensuring compliance and operational reliability. This solution enables uninterrupted service delivery, supports local community work initiatives, and improves efficiency in voucher management and administration.

Challenge

VDAB needed to quickly develop the new wijk-werkcheque platform to manage district work vouchers after their external provider discontinued the service.

Solution

ACA Group developed a portal for employers and a support platform for VDAB staff, using innovative technology and integrating with existing systems.

Result

VDAB successfully transitioned to managing digital district work vouchers internally, ensuring efficiency and sustainability while strengthening their partnership with ACA.

The district work voucher system (‘wijk-werkcheques’ in Dutch) was introduced by VDAB in Flanders in 2004 to help individuals facing challenges in accessing the conventional job market engage in community-based tasks. This system allows local community organizations, governments, and individuals to hire district workers for various tasks, from garden maintenance to administrative support. Workers receive compensation through district work vouchers, partially funded by the Public Employment Service of Flanders (VDAB).

However, in 2022, Edenred, the external issuer of these vouchers, announced they would discontinue the service. VDAB urgently needed a solution to manage and distribute the district work vouchers internally, as the search for a new external partner yielded no immediate results. With their internal software teams occupied with roadmap projects until 2025, VDAB sought the expertise of ACA Group to develop a new application for voucher management.

ACA Group collaborated closely with the VDAB specialists to create a comprehensive platform consisting of two key components:

District Voucher Portal: This portal allows employers to purchase and manage electronic district work vouchers and facilitate payments to district workers. The decision to exclusively use electronic vouchers enhances efficiency and supports environmental sustainability.
Support Platform: This platform equips VDAB staff with comprehensive data and analytics on employers and district workers. It includes a service desk section for user assistance, ensuring smooth operations for all stakeholders.

The project kicked off in November 2022, with initial months focused on establishing a solid backlog through collaboration between analysts and architects. From January to June 2023, a dedicated development team created a sleek application that integrated seamlessly into VDAB's existing technological framework. By leveraging an established technical API, the team laid a sturdy foundation for the new application.

The technology stack used included Spring Boot, Hibernate, and Jackson for the backend, and Angular for the frontend, ensuring a modern, service-based architecture that adheres to best practices in domain-driven design.

The final delivery of the district work voucher application was scheduled for the end of 2023, marking the start of the new voucher issuance process. Until then, Edenred continued to support the old vouchers.

The collaboration between VDAB and ACA Group has been a resounding success, extending beyond this singular project into a long-term partnership built on mutual trust and professional synergy. As a result of this collaboration, several ACA consultants remain part of the permanent software team at VDAB to tackle ongoing software challenges.

Future joint projects promise to enhance VDAB’s service delivery and internal operations, contributing significantly to the success of VDAB in supporting job seekers across Flanders.

With the help of the ACA team, VDAB managed to take over the issuing of district work vouchers and the processing of the necessary payments and disbursements from an external issuing company and to internalize them against a strict deadline.

Goodbye, paper maze! We developed the Gebouwenpas, a single digital platform that brings together all real estate data

The Flemish government (public sector) faced fragmented real estate data spread across multiple agencies, making it difficult for citizens and stakeholders to access certificates, permits, and reports. ACA Group developed the Gebouwenpas, a scalable digital platform built on Liferay DXP with Spring Boot and Angular, centralising all building data into a single digital passport. Using an agile Scrum and Kanban approach, the solution delivers clear insights, secure access, and a future-proof system for both residential and non-residential properties.

Getting more out of Jira data: how I am ten gains better insights with JirAlytics

I am ten, a marketing agency working with diverse project types such as retainers and time-based assignments, struggled to turn fragmented Jira data into actionable management insights. ACA Group implemented JirAlytics, a data platform built on top of Jira that integrates with tools like Power BI to centralise reporting on billability, budgets, and timesheets. This resulted in a scalable, centralised reporting environment, enabling management to monitor performance and make faster, data-driven decisions across all projects.

OVAM accelerates digitalization with Low-Code: fast, efficient, and cost-saving

OVAM, the Public Waste Agency of Flanders, faced operational inefficiencies due to legacy IT systems and manual processes in case management and field operations. ACA Group implemented multiple applications using OutSystems low-code technology, including a web-based case management system, a mobile inspection app, and an asbestos cost calculation tool. This approach automated workflows, improved data accuracy, and reduced administrative effort, enabling faster processes, scalable digital solutions, and cost-efficient digital transformation across the organization.

Mijn Stadsapp: +20 municipalities in 1 mobile app

Smart Region Limburg (s-Lim), a collaboration of local governments, needed to reduce fragmentation in municipal communication and services across multiple municipalities. ACA Group developed Mijn Stadsapp, a cross-platform mobile application built with React Native that integrates data from various sources such as municipal websites, event platforms, and utility services. This solution centralizes local information and services in one app, improving citizen engagement and accessibility, and achieved rapid adoption with over 20,000 downloads in the first month.

A Data Mesh Journey from Strategy to Implementation at a Belgian major bank.

A major Belgian bank needed to modernize its data management strategy to overcome limitations of centralized data architectures and enable scalable, domain-driven data usage. ACA Group guided the transition to a Data Mesh approach, combining strategic consulting, stakeholder alignment, and hands-on implementation of a self-service data platform using technologies such as Kubernetes. This resulted in a validated data product model, improved data ownership, and a scalable architecture that accelerates data-driven innovation and governance across the organization.

How our onboarding platform gives new colleagues a flying start. (And saves HR a lot of time)

ACA Group, an international technology consultancy, faced fragmented onboarding processes across multiple offices, tools, and business units, creating inefficiencies for HR and inconsistent employee experiences. To address this, ACA Group developed N-ACA, a custom onboarding platform built with OutSystems low-code technology. The platform centralizes onboarding content, enables progress tracking, and standardizes workflows. This solution improved onboarding quality, reduced administrative workload for HR, and accelerated time-to-productivity for new employees.
