Guyamier’s successful TMS migration: 7 entities and 170 users moved to Dashdoc in the middle of the holiday season. A look back at an ambitious project.
A Multi-Service Carrier That Thinks Big
Guyamier is a trucking group based near Bordeaux that specializes in freight between France and the UK. It has 170 employees, including 20 dispatchers and 150 drivers, and runs a wide range of operations: curtainside, container, flatbed, and lowboy transportation, along with truck rental and freight brokerage. Guyamier also hauls hazardous materials and runs its operations in two currencies, euros and pounds sterling. The group recently brought its 3 Bordeaux-area sites together and launched an ambitious digital transformation project.
The Challenge: Migrating 7 Entities During the Holidays
Switching TMS is already a challenge. Doing it across 7 entities at once, in the middle of the holiday season, is a bold bet. That’s exactly what Guyamier decided to do.
The project kicked off in October 2025 with a clear goal: be up and running by January 2026. In the meantime, the team had to roll out Dashdoc across every entity in the group, integrate several industry tools (Shippeo, Transporeon, EDI integrations for creating container orders, and AddSecure), handle multi-currency loads, and train 170 users. All of this happened over the year-end holidays, the most sensitive time of year for freight operations.
It may sound crazy, but the group was convinced that with the right support and solid organization, the bet could pay off.
The Solution: Tailored Support and Strong Champions on the Ground
Cécile, a project manager at Dashdoc, supported Guyamier throughout the transition. On the customer side, the group appointed Bastien Dulucq, its management controller, as project lead.
“Bastien was the key on the customer side: he had the big picture, he was our link to the field, and he was always available. We also identified power users to share best practices. That combination is what allowed us to roll out 7 entities in 3 months.”

On-site support took place in late December, right in the middle of the holidays. Thanks to the upfront preparation and the teams’ commitment, the migration went off without a hitch.
The Result: A Successful Migration That Delivered Value from Day One
By January 2026, the bet had paid off. All 7 entities were up and running on Dashdoc. The migration, which some had dreaded, turned out to be a complete success.
“The migration to Dashdoc was a real success: a fast rollout, outstanding support, and value from day one. We’ve gained efficiency, visibility, and peace of mind in how we manage our operations.”

The group also highlights the human side of the support it received:
“On behalf of Groupe Guyamier, we want to thank Cécile for her kindness, her availability, and the care she showed every one of our employees throughout this transition.”

Today, Guyamier manages its 170 users on a single platform, with its industry integrations up and running and real-time visibility across all of its operations. What once seemed crazy is now a reality.
