In 2024, the TPE market is undergoing a profound transformation. Driven by the arrival of players such as Pennylane or Tiime and by the impending reform of electronic invoicing, the demand for simple, all-in-one and self-service tools is exploding.
Cegid
Cegid, the historical leader in management software (Loop, Quadra, Hubbix), wishes to capitalize on its expertise to create BIM!, a new SaaS platform capable of:
- to support the life of a small business from its first bill to the analysis of its profitability;
- to unify its existing products into a modern and modular technical base;
- to accelerate the marketing of a competitive offer in the face of new entrants.
To achieve this, Cegid must both quickly deliver a differentiating MVP and mitigate the risks of a structural overhaul of its architecture.

1. Federate several products around a unified platform
Fusion of backends, technical harmonization and redesign of the design system to offer a coherent experience.
2. Deliver a differentiating MVP in less than 6 weeks
New quote/invoice process, designed to immediately test market appetite.
3. Modernizing a historic monolithic stack
Transition to a modular architecture (DDD, microservices, React Native) without interruption for existing users.
4. Align the product roadmap with very heterogeneous TPE uses
From freelancers to structured SMEs, the experience must adapt to varied needs.
Our approach
For 7 weeks, a multidisciplinary Theodo Fintech team joined the Cegid teams to accelerate delivery, de-risk the architecture and lay the foundations for a scalable platform.
Complete audit to de-risk redesign (Right-first-time)
A structured diagnosis of architecture, data and product organization (3S frameworks and Marty Cagan) to identify critical risks and secure technical choices.
Acceleration of delivery thanks to a network of teams aligned by value
Detection and removal of obstacles (design, quality, delivery) in order to accelerate the achievement of the MVP while guaranteeing smooth execution between the Cegid and Theodo teams.
Technological harmonization for a gradual rise in power (Just-in-Time)
Unification of the design system, modernization of the backend, optimization of CI/CD practices and modular prioritization by areas (quotes/billing, finance, accounting).
Our impact
A unified SaaS platform in 7 weeks, with immediate impact
Merger of BIM x Cegid Business backends: -40% code, -30% in estimated operating costs
Time-to-market divided by 3
- A first quote/invoice module designed for immediate adoption.
- Modernized, fluid and consistent experience with the standards of the best Fintech SMB.
