Frequently asked questions

Getting it exactly right

Turnkey or bespoke solution for a premium brand?+
A turnkey solution like Shopify suits most premium brands: quick to launch, mature, robust, with a broad extension ecosystem. A bespoke platform is only justified for complex multichannel presence, advanced personalization or performance requirements, with a gain of 15 to 35% in mobile conversion. On the Swaine case, the bespoke route produced +47% mobile conversion.
Which solution for a high-volume B2B eCommerce?+
A packaged professional solution or bespoke development. The criteria: multi-user business accounts, per-account custom catalogs, online quotes, deferred payment terms, and integration with your ERP, often critical. Bespoke for complexity, packaged for ease of implementation.
Do you migrate an existing store (Shopify, WooCommerce, PrestaShop)?+
Yes. We migrate from Shopify, WooCommerce, PrestaShop or Magento to the solution best suited to your project. The switch preserves your catalog, customers, order history and, above all, your SEO: redirect plan, URL preservation, product structured data. The goal is zero loss of organic traffic at launch.
How do you handle VAT internationally?+
Through the OSS (One-Stop Shop) regime for intra-EU sales, which centralizes VAT declaration. Beyond the EU, management gets more complex (thresholds, customs, local taxation). We configure the platform and the accounting flow to automate calculation and collection, in coordination with your accountant.
Which payment provider for a growing brand?+
Some providers prioritize flexibility and speed of setup, ideal in a growth phase. Others excel at high volumes, fine-grained optimization of acceptance rates and international multi-method payments. The choice depends on your volume, your markets and your solution.
How do you fight fraud?+
Through strong payment authentication, the protections built into providers and, where the stakes are high, specialized solutions. The goal is to keep fraudulent chargebacks below 0.5% without degrading the conversion rate through unnecessary friction.
Can you set up in-store pickup (click-and-collect)?+
Yes. We connect store inventory to the website, manage reservation and pickup, and unify the experience between web and point of sale. Click-and-collect simplifies delivery and drives store traffic, provided ERP integration and inventory management are reliable.
Do you handle customer service above 1,000 requests per month?+
Yes, with tools sized for the volume, prepared responses, a knowledge base and automated handling of routine requests. We structure guaranteed response times, routing and escalation, and measure resolution time and satisfaction, to absorb the volume without degrading quality.
What does generative AI bring to eCommerce?+
A lot, provided it is governed: generation and enrichment of product pages, personalized recommendations, natural language search, customer service assistance, predictive segmentation. As elsewhere, AI is a production accelerator under human validation, never an autopilot left unchecked.
How do you measure the results of a redesign?+
Through indicators committed from the scoping stage: conversion rate, average order value, customer lifetime value (LTV), organic traffic and return rate. We take a baseline before the redesign, then track their progress after launch. Results are read in the measured evolution of these indicators, not in promises.
Should you centralize all your data?+
Beyond a certain level of activity, yes. A data warehouse unifies all your sources (store, marketplaces, CRM, advertising) in one place and lets you reactivate that data precisely in your campaigns. It is the shift from fragmented, tool-by-tool steering to unified, data-driven steering.
Do you handle institutional and cultural stores?+
Yes: museum stores, ticketing, foundations. These projects combine sales, ticketing and sometimes tax receipts, with requirements around compliance, accessibility and often sovereignty. We adapt the platform and the purchase journey to these specific constraints.
