The challenge
Making money available to employees as fast as possible
What Hexeko sells to companies is value-added money that comes with specific benefits and tax exemptions. Once Hexeko customers fund their accounts, this money must be available to companies employees as fast as possible. Employees can use this money via cards issued by Stripe. To run their services, Hexeko operates two main payment flows:
- Incoming payments: Hexeko collects funds via direct debit or bank transfers made by its customers
- Outgoing payments: Hexeko makes the funds available to employees on their cards by making payments to Hexeko’s Stripe accounts.
Today, these flows represent dozens of millions of euros processed per year. They are at the core of the value Hexeko delivers to its customers. To support the growth of Hexeko’s and Group Up's activities, including the digitalisation of Group Up's paper voucher-based activity, Hexeko needed to make this core workflow and the infrastructure supporting it more robust.
The solution
Optimising payments on top of existing systems and processes
When looking for a solution, Hexeko evaluated various treasury management systems. None met their automation needs. Hexeko also evaluated open banking solutions to collect payments, but the required strong authentication required from customers would have introduced too much friction and negatively impacted user experience.
The Hexeko team decided to implement Mambu Payments to solve their automation needs while keeping their current bank BNP Paribas and providing a frictionless customer experience.
Mambu Payments is connected to Hexeko’s BNP Paribas accounts in France and Belgium. On Hexeko’s side, Hexeko internal systems directly integrate with Mambu Payments via API. Mambu Payments is connected to Stripe and many other solutions through these internal systems. “For instance, we can automatically trigger a payment via Mambu Payments when receiving a Stripe webhook”, shares Guillaume Dasnoy, CFO at Hexeko.
“Even without considering our planned growth, the situation was already critical. The Hexeko team member in charge of these payments had no time left for their treasury tasks, and we had to hire contractors to support us in the peak weeks. We couldn’t have managed our upcoming growth without Mambu Payments.”

The result
Saving 120 days per year on payment operations
At current volumes, manually reconciling incoming payments and sending them took Hexeko’s team 10 days per month. This work was concentrated around the end and beginning of the month when companies were topping up their accounts for their employees. Automating the workflows with Mambu Payments, Hexeko also reduced payment and reconciliation errors.
In addition to bank payments sent by its customers, Hexeko also collects part of its customer payments via direct debits. Next on Hexeko’s payments roadmap is to leverage BNP Paribas through its Mambu Payments integration for direct debits, currently managed via Stripe.
After direct debits, Hexeko plans to enable companies to automatically reimburse benefits paid by employees themselves. These payments to employees’ personal bank accounts will be processed via Mambu Payments.
“The implementation of Mambu Payments has been straightforward, requiring only part of one developer’s three-week sprint. Before we could allocate our developer to the implementation, we’ve been able to start automating most of our workflows by importing CSV files through the Mambu Payments dashboard.”
- Guillaume Dasnoy, CFO at Hexeko
