For 14 years, Callista has been helping companies work smarter, more efficiently and in a future-proof way with Odoo, the powerful and flexible ERP platform.

What started as an ambitious idea has grown into a leading Odoo partner with more than 350 successfully completed projects. From our offices in Kalmthout and Meerhout, a team of 30 driven professionals works with our clients every day on digital solutions that truly make a difference.

Our strength? 
Personal commitment, technical expertise and an approach that goes beyond software alone. We listen to our clients, understand their challenges and build solutions that grow with their business. The result is a client retention rate of no less than 94,92% – a figure we are particularly proud of.

Ready for the future?

The digital world never stands still, and neither do we. Callista keeps investing in quality, innovation and lasting partnerships. 
Our ambition is to keep growing in the years ahead, 
both in team size and in number of locations, without losing sight of our personal approach.

Because for us, digitalisation is not just about technology. 
It is about making companies stronger, organising processes more smartly and building sustainable growth together.

Today and tomorrow. Together with our clients.

Callista: more than an Odoo partner, your partner in growth and innovation.​
