Keep that in mind as you read, and ask us these questions too On paper, almost every eCommerce consultant promises a tailored, results-driven approach. What sets them apart is how they answer specific questions ## 1. What will you ask me before proposing anything? A consultant who presents a solution in the first meeting is selling what they know how to do. They should first want to understand your business model, your margins and what you have already tried ## 2. Can you show me a case close to mine? Ask for the starting point, what was done, the result and the timeframe. An isolated percentage does not prove much ## 3. How will you measure success? More traffic is useless if it does not convert, and more sales are useless if they are not profitable. The consultant should name the metrics before starting ## 4. What do you look at beyond acquisition? The [basic eCommerce formula](https://www.nexperio.com/en/blog/formule-magique-ecommerce-trafic-conversion-panier) combines traffic, conversion rate and average order value. A good diagnosis examines the whole journey and customer retention, not just the ad budget ## 5. Have you ever been accountable for an eCommerce result? Giving advice and answering for a P&L are two different experiences. Ask which roles the consultant has held and what really depended on them ## 6. Who will do the work? You are buying people. Ask to meet the ones who will be involved, and ask what gets delegated to third parties ## 7. What happens if it does not work? The answer reveals how the consultant works: checkpoints, criteria for changing course, exit terms. A contract should cover this case ## Our answers, for comparison - **Method:** in-depth questioning of the need, a restatement with areas to work on, then a jointly built roadmap - **Cases:** our [two anonymized cases](https://www.nexperio.com/en/cas-de-guerison) detail the context and results, and Felipe Jacome, CEO of Melissa, says: "Nexperio helped us completely rethink our digital strategy and our customer relationship. Results from the online sales channel doubled in 6 months" - **Accountability:** [Arnaud Guedj](https://www.nexperio.com/en/le-docteur-digital) ran eCommerce for Southern Europe and part of the EMEA region at Lenovo before founding Nexperio These answers are ours: it is up to you to judge whether they suit your situation. The [free diagnosis](https://www.nexperio.com/en/rdv) exists to check exactly that ## Frequently asked questions ### Can an eCommerce consultant guarantee results? Be wary of a numeric guarantee given before any diagnosis. Results also depend on your product, your margins and your ability to carry out the recommendations ### Should I choose a consultant who specializes in my platform? That helps if your problem is technical. If the blocker lies in strategy, your offer or profitability, knowledge of your business model matters more ### How can I tell whether a consultant really achieved the results they claim? Ask for the starting point, the scope and the timeframe, then a client contact where possible. If the client is anonymized, the precision of the account becomes your main basis for judgment eCommerce Consulting Conversion 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 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.
