Our view is therefore not neutral, and the limits of our category are listed too Looking for the best consultant often means comparing players who do not do the same job. It is better to decide first what type of partner you need ## Three types of partner | | Specialist consultant or firm | Generalist firm | Agency | | --- | --- | --- | --- | | **Strength** | Fast diagnosis, knowledge of the trade | Company-wide view, change management | Production and execution capacity | | **Limit** | Smaller team capacity on very large programs | eCommerce expertise varies with the assigned team | Risk of recommending what it knows how to produce | | **Suited if** | The problem sits in the online channel, or still needs diagnosing | eCommerce is part of a broader transformation | The strategy is clear and needs executing | These options are not mutually exclusive. A diagnosis by a specialist followed by execution by an agency is a common setup ## Three questions to decide 1. **Do you know exactly what is wrong?** If so, look for someone who can execute. If not, start with a diagnosis 2. **Do you have the teams to apply the recommendations?** If not, advice without execution will just gather dust 3. **Does the problem go beyond eCommerce?** If the organization, IT systems or governance are involved, a broader scope may be justified ## Before you call anyone You can already do part of the work yourself.

A consultant helps you decide what to do and why, while an agency produces and executes. Many players do a bit of both, so ask what is really done in-house ### Is a generalist firm suitable for an eCommerce project? Yes, when eCommerce is part of a broader company transformation. For a problem specific to the online channel, a specialist will generally reach a diagnosis faster ### Do small businesses need an eCommerce consultant? Not necessarily. Many can start by measuring their situation with free tools, then bring in a consultant for a specific problem eCommerce Consulting France On the same topic ## Read also ![Best eCommerce Consulting Firm in France: How to Choose in 2026](https://www.nexperio.com/_next/image?url=%2Fblog%2Fmeilleur-cabinet-conseil-e-commerce-france-comment-choisir.jpg&w=3840&q=75&dpl=dpl_4XUbjamZWrvNptwDouTo3cM1NGRy) eCommerce 4 min ### Best eCommerce Consulting Firm in France: How to Choose in 2026 ![Best eCommerce Consultant: 7 Questions to Ask Before You Sign](https://www.nexperio.com/_next/image?url=%2Fblog%2Fmeilleur-consultant-e-commerce-comment-choisir-votre.jpg&w=3840&q=75&dpl=dpl_4XUbjamZWrvNptwDouTo3cM1NGRy) eCommerce 4 min ### Best eCommerce Consultant: 7 Questions to Ask Before You Sign ![PHP security flaws: what small online stores need to check](https://www.nexperio.com/_next/image?url=https%3A%2F%2Fqarqnjzixkkunhdzgule.supabase.co%2Fstorage%2Fv1%2Fobject%2Fpublic%2Fblog%2Ffailles-php-site-ecommerce-pme%2Fcover-fc35daa4de31.jpg&w=3840&q=75&dpl=dpl_4XUbjamZWrvNptwDouTo3cM1NGRy) eCommerce 5 min ### PHP security flaws: what small online stores need to check ![Nexperio](https://www.nexperio.com/assets/nexperio-logo-original.png) Diagnostic offert ## Ne tentez pas de vous soigner sans ordonnance Parlez-moi de votre business.
