Part time, full time, on-site, hybrid or remote

Part time or full time

Recognizing that not all roles necessitate a full-time consultant, Altesia provides flexible staffing solutions tailored to your exact needs. Our consultants (payroll or interim managers / freelancers) are available to assist you for the time needed, from 1 up to 5 days a week, ensuring you receive the exact right level of support: no overselling or underdelivering

 

On-site, remote or hybrid

Beyond time commitment, our consultants can work entirely on your premises, in a hybrid setup, or fully remote depending on what fits your organisation, your team rituals, and your budget. Our remote setup gives you access to senior expertise at an optimised cost.

Several expertise levels for one full-time equivalent

For missions demanding specific expertise or a blend of senior and mid-level skills, we provide a collaborative, flexible and budget-friendly approach: an interim manager such as a CFO, Procurement Manager or Human Resources Manager, or even an Altesia Partner, can team up with the consultant.

This combination ensures that you receive both high-level expertise while maintaining operational consistency and long-term execution. This means that you get varied levels of expertise for the budget of a single full-time employee (FTE).

This efficient approach eliminates the need to hire an overqualified executive for day-to-day operations and avoids the unnecessary expense of employing two full-time professionals when the workload doesn’t require it.

What our clients say

  • Thibaut Devroye Group Accounting & Consolidation Manager, Elia

    With Altesia, we didn’t just get a consultant: we got a structured, high-quality approach that truly makes a difference.
    The 3 consultants we worked with delivered excellent results, but what stood out was the way they were coached and supported. Altesia’s reporting method and regular partner touchpoints brought clarity, discipline, and follow-through to every task.

  • Didier De Vos SVP EMEA Service & Solutions, Glory

    Every profile Altesia proposed was spot on, operational, reliable, and adapted to our complex environment. In less than a week, I had someone in place: skilled, available, and ready to take over. That level of responsiveness made all the difference.

  • Mohamed Ahmaidi Controlling Manager, Lavafields

    The Altesia consultants I’ve worked with have always been people who adapt quickly, listen, understand our environment, and move things forward without ever pushing their way through. Their screening process is clearly rigorous: the technical skills are there, of course, but what truly stands out is their emotional intelligence. Their consultants know how to integrate seamlessly, read the room, and adjust their approach. That makes the difference.

  • Alexandre Richel CFO, Monizze

    Altesia’s added value is the follow-up. The consultant isn’t left on their own, and I have a trusted partner I can call whenever I need expert advice. I don’t just get a consultant, I also get access to the partner, who acts as a sounding board for more strategic topics.

  • Nicolas Putzeys Director Finance & Infrastructure, EPHEC

    What really stood out with Altesia was the value for money and the quality of execution. The consultant was hands-on from day one, backed by a partner who clearly followed the mission closely and stepped in with senior expertise whenever needed.

     

    Everything was structured, monitored, and transparent. I could see the detailed follow-up, even when I didn’t have time to look myself. And above all, their approach was truly practical: no glossy slides, just sleeves rolled up and real work that moved things forward. The perfect mix of impact, senior insight, and efficiency.

  • Soumya Chandramouli CFO Novadip
    Soumya Chandramouli CFO at Novadip

    Altesia’s consultant, Katya, made my onboarding as a new CFO much smoother. She walked me through everything she was handling. She kept things running so I could settle in without disrupting the team. We also took the time to challenge a few existing processes and see what we could improve.

Frequently asked questions

  • 01

    What is interim management, and when should you use it?

    Interim management means bringing in an experienced professional — in finance, procurement or HR — for a defined period to lead or stabilise a function during a transition, a departure, a peak in workload, or a transformation project. It is the right choice when you need senior expertise operational quickly, without a permanent hire.

  • 02

    What is the difference between staffing, interim management and advisory?

    Staffing places a consultant within your team to deliver operationally, from junior profiles to interim CFOs. Interim management is staffing at a senior, leadership level for a defined mandate. Advisory provides senior strategic counsel and recommendations, with optional hands-on implementation. Altesia combines the three so the support matches the need exactly.

  • 03

    How quickly can an Altesia consultant be operational?

    Depending on the profile, Altesia can have a skilled, available consultant in place within about a week, ready to take over with minimal disruption to your team.

  • 04

    Can I hire a consultant part-time?

    Yes. Altesia provides flexible staffing from 1 up to 5 days a week, part-time or full-time, matched to operational needs or urgent situations.

  • 05

    Which functions and company sizes does Altesia support?

    Altesia supports SMEs, scale-ups and large organisations in Belgium across finance, procurement, HR and tax & accounting, from junior consultants to interim CFOs.
