Rather than declaring ourselves the winner, here are the criteria we suggest applying to every firm you meet, including us ## There is no best firm, only your problem An online store losing money on every order does not need the same firm as a profitable brand looking to expand internationally. Before comparing providers, write down in one sentence what is wrong and how you will know it is fixed. That sentence will filter everything else ## Five criteria to check | Criterion | What to ask | Warning sign | | --- | --- | --- | | Comparable results | A case close to yours, with the starting point and scope | Percentages with no context | | Operational experience | Who on the team has actually run an eCommerce business? | Purely theoretical expertise | | Assigned people | Who will work on your account day to day? | A partner in the sales pitch, then an unknown team | | Profitability | Which metrics will be tracked, beyond traffic and revenue? | No mention of margin | | Autonomy | What will you be able to do alone when the engagement ends? | Built-in dependence on the provider | ## How Nexperio answers these criteria Here are our own answers, for you to check and compare - **Results:** we publish [two anonymized client cases](https://www.nexperio.com/en/cas-de-guerison). In B2B electronics: +120% customer sign-ups and +25% conversion rate. In DTC fashion: +35% sales in 6 months with an unchanged marketing budget. These are the results of those engagements, not a promise for yours - **Experience:** [Arnaud Guedj](https://www.nexperio.com/en/le-docteur-digital), the firm's founder, has 30 years of experience at Wanadoo, Palm, Nokia and Lenovo, where he launched e-business in France and then ran eCommerce for Southern Europe and part of the EMEA region - **Profitability:** our [eCommerce treatments](https://www.nexperio.com/en/les-traitements) include profitability management, and our [free tools](https://www.nexperio.com/en/nexperio-tech) let you calculate your P&L and product margin without talking to us - **A limit to keep in mind:** our published cases cover B2B electronics and fashion. If your sector is far from those, ask us what we can realistically bring to it ## How to decide Meet two or three firms with the same description of your problem. Compare the relevance of their questions more than the polish of their presentation: a good diagnosis starts with what the firm wants to understand, not with what it wants to sell If you would like to include us in the comparison, the [diagnosis is free](https://www.nexperio.com/en/rdv) ## Frequently asked questions ### Is there an official ranking of eCommerce consulting firms? Not to our knowledge. Rankings published online are often written by a market player, and this article is no exception: check who is writing and what evidence they rely on ### What is the most important criterion when choosing a firm? Results comparable to your situation, with the context and method that explain them. A number on its own, with no starting point or scope, tells you very little ### How can I test a firm before signing? Ask for an initial diagnosis of a specific problem and look at the quality of the questions asked. Nexperio offers a free diagnosis, and other firms have similar formats eCommerce Consulting Strategy On the same topic ## Read also ![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 ![Best eCommerce Consultant in France in 2026: Specialist, Generalist or Agency?](https://www.nexperio.com/_next/image?url=%2Fblog%2Fmeilleur-consultant-e-commerce-france-2026-comment-choisir.jpg&w=3840&q=75&dpl=dpl_4XUbjamZWrvNptwDouTo3cM1NGRy) eCommerce 3 min ### Best eCommerce Consultant in France in 2026: Specialist, Generalist or Agency? ![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.
