Adapting Finance to support fast-scaling growth at Monizze

Background

Monizze, a fast-growing scale-up with nearly 140 employees, provides electronic voucher solutions for companies.

As the organization expanded rapidly, it needed to evolve its finance function to keep pace with ongoing transformation.

When he took office, the Finance & Administration Manager, Alexandre Richel, was managing a very broad scope alone — finance, legal, office management, fleet, and office relocation — with a limited accounting tool (Winbooks) and a small team.

In this context, Monizze initially reached out to Altesia for a one-off assignment. The collaboration quickly went beyond the initial scope, evolving into continuous transformation support.

The objectives were to:

Develop the administrative and accounting function into a true business partner, providing financial visibility, enabling profitability analysis, and supporting decision-making.
Upgrade systems by migrating to a more robust ERP (Odoo).
Structure and strengthen the team through permanent hiring and temporary staffing.

“Where I see Altesia’s added value is that I’m not just hiring a consultant — I automatically get access to the partner, Cédric Van Themsche, as well. Cédric knows our organization, provides a strategic sounding board and practical advice… without ever trying to sell hours just to sell hours.”

- Alexandre Richel, Finance & Administration Manager, Monizze

Approach

A pragmatic and targeted diagnostic

The collaboration started with an internal financial diagnostic mission, soon expanded into a broader reflection on the future of the finance function.

Cédric Van Themsche, Partner at Altesia, led the diagnostic to identify key priorities: organization, tools, and business partnering mindset.

No unnecessary complexity: the team chose an agile approach, based on focused interviews to spot key risks without exhaustive testing, delivering a relevant, fast, and cost-conscious assessment aligned with Monizze’s budget constraints.

Progressive reinforcement

Two Altesia consultants successively joined as Business Controllers: first Virginie Siriez, then Antoine Grégoire. This step-by-step reinforcement allowed the finance function to be progressively and sustainably structured.

As with all staffing missions, the collaboration included direct follow-up by a Partner in Charge — in this case, Cédric Van Themsche. He remained a strategic contact point, both to support the in-house consultants through Altesia’s Quality Engagement methodology and to act as an expert or “sounding board” on complex or strategic matters (transfer pricing, financial organization, etc.).

This flexible model gives Monizze a “consultant + partner” setup — a highly valued combination that provides both operational expertise and strategic vision.

Targeted interventions to support transformation

Beyond the initial diagnostic and staffing, Altesia stepped in with other ad hoc consulting support as new needs emerged:

Permanent recruitment — helping Monizze hire an internal accountant, stabilizing the finance team.
ERP migration — Manon, an Altesia consultant, is leading the migration from Winbooks to Odoo.
Negotiation (procurement) — Marcos Viale, Partner of the Procurement Business Unit, supported the negotiation and contracting with the Odoo integrator.

Results

Strengthened finance team: the team is now structurally reinforced with an internally hired accountant and Altesia’s ongoing financial consulting support. Extra resources can be added when needed for specific issues.
Shift to business partnering: moving beyond transactional tasks to profitability analysis and decision-making support for managers.
Modernized tools: ERP migration to Odoo underway, improving efficiency and reliability.
Flexibility and cost control: targeted missions, no unnecessary overhead, adapted to a scale-up’s real needs.
Trusted partnership: a direct, transparent relationship with the partner staying involved and accessible, giving Monizze a true financial co-pilot.
