Energie.be and ACA Group develop Tariefcheck: quickly and smartly compare energy contracts

ACA Group developed the Tariefcheck, a web-based calculator that analyzes usage data to estimate potential savings. This digital solution improves customer insight, simplifies tariff comparison, and increases engagement by enabling users to quickly identify savings of up to €1,000 per year.

About Energie.be

Energie.be is a Belgian energy provider focused on transparency, simplicity, and competitive pricing. With a promise of "honesty above all," they offer 100% transparency on their consistently low rates—no hidden fees or complex terms. Energie.be makes switching providers as straightforward as possible and provides practical tools, such as the Tariefcheck, to empower customers to uncover their savings potential and make informed decisions about their energy contract.

Challenge

Helping customer maximize savings

Tom Van Den Bosch, CEO of Energie.be, explains that many Belgian households are paying far too much for energy: "Over 1.2 million households pay up to €1,000 too much annually. Despite our competitive prices, larger providers with complex and misleading pricing strategies dominated the market. That’s why we wanted to create a simple, effective way to raise awareness about savings potential and enable consumers to choose a provider that’s the best long-term option."

The solution? A personalized Tariefcheck that lets consumers instantly see if and how much they can save, and switch providers within 30 seconds.

"It needed to be better than existing comparison websites that only evaluate the current offers from other providers without accounting for your current contract, which you might have signed months ago", adds Tom.

The tool doesn’t just provide immediate insights into potential savings, it also accounts for complex scenarios like variable rates and social tariffs. Weekly meetings and rapid iterations made sure that these exceptions were handled effectively.

A better and faster comparison tool

To develop this tool efficiently, Energie.be partnered with ACA Group. Tom explains: "We organized a hackathon together to rapidly build the Tariefcheck. ACA approached the challenge with a critical eye and began development immediately."

In collaboration with Energie.be’s team, ACA Group outlined all user stories and designed the tool. Thanks to their technical expertise, the first version of the Tariefcheck was delivered in just 1.5 months.

Efficiency and simplicity

In addition to developing the Tariefcheck, ACA Group helped optimize Energie.be’s internal processes. Previously, comparing a customer’s invoice to current market offerings was a manual and time-intensive task. ACA implemented a system that automatically recognizes and processes invoice data, dramatically improving efficiency.

"This saves us not only time but also costs", says Tom. "The Tariefcheck makes it easier for customers to save and simplifies the work for our customer support team."

How CM secured its new Atlassian Cloud with Azure Entra ID

CM, a Belgian health insurer, migrated its Atlassian environment from Data Center to Cloud, with integration into Azure Entra ID as a requirement. The technical integration through Atlassian Guard was easy to set up. The real challenge was operational: deciding in which platform licences, groups and permissions are managed. ACA Group listed the decisions to make, guided and advised CM, and made sure all stakeholders were informed and aligned. The result: licences managed in Azure Entra ID, permissions in Atlassian groups, and an enterprise-grade identity and security solution with clearly defined roles and responsibilities.

How Stellantis moved 150.000 Jira issues to the cloud, without downtime

When Stellantis  inherited an outdated Jira Server environment, simply moving everything to the cloud was not the answer. Years of duplicate fields, inconsistent workflows and legacy configuration would have moved with it. They wanted something better: a clean Jira Cloud environment without losing years of valuable history or disrupting its teams.

Together with ACA Group and Exalate, Stellantis migrated around 150.000 Jira issues in just 25 days, while cleaning up and restructuring its data along the way.
