Top 10 E-commerce app developers in Paris

Planning a e-commerce app in Paris? Below are 10 development teams worth shortlisting, ordered by the e-commerce work and shipped apps they can point to. Agency rates in Paris typically run €600-€1,500/day, and a mVP app (cross-platform) usually costs €10,000 – €40,000 on the local market. Most e-commerce apps launch cross-platform first; the guide below covers platforms, costs and what to ask before you sign.

How this list works. Agencies are ordered by the e-commerce evidence in their public profiles: stated specialisms, platforms and named sector work (several are primarily web studios, so ask for shipped apps), so the Paris order changes by industry. Tecklogist ranks first. This list is published by Tecklogist; no other agency pays for placement.

How to choose an e-commerce app developer

The checks that separate genuine e-commerce specialists Before you sign with any e-commerce app developer in Paris, check these points in the first call. Good teams answer them with live examples rather than promises.

  1. 01

    Live e-commerce apps you can download

    Ask for App Store and Google Play links to apps the team shipped, then read the reviews and check when each was last updated.

  2. 02

    Experience with e-commerce features

    Bookings, payments, accounts or records work in e-commerce apps has edge cases. Ask how they handled them before.

  3. 03

    Ownership from day one

    The code repository, Apple and Google developer accounts and signing keys should be registered to your company, not the agency.

  4. 04

    Backend and admin panel included

    Most e-commerce apps need a dashboard for your team. Make sure it is in the quote, not a later surprise.

  5. 05

    A plan for after launch

    IOS and Android updates break apps every year. Agree a maintenance plan or clean handover before you sign with any Paris team.

Native, React Native, Flutter or PWA?

React Native

Choose it for: One codebase for iOS and Android, a TypeScript team, and logic shared with your website.

Flutter

Choose it for: Identical UI on both platforms, rich animation, or plans to reach desktop later.

Native (Swift / Kotlin)

Choose it for: Deep device features: Bluetooth hardware, background location, AR, HealthKit or demanding real-time performance.

Progressive web app

Choose it for: Something installable fast on a small budget, where App Store discovery does not matter.

E-commerce app development in Paris: FAQs

How much does an e-commerce app cost in Paris?+

In Paris, a mVP app (cross-platform) typically costs €10,000 – €40,000, while a native iOS or Android runs €35,000 – €150,000. Agency day rates of €600-€1,500/day are the main driver, followed by integrations and how much custom functionality you need. Tecklogist quotes e-commerce projects from from €1,499 at a fixed price.

How long does it take to build an e-commerce app?+

A mVP app (cross-platform) usually takes 4–8 weeks; a native iOS or Android takes 8–24 weeks. Delays almost always come from late content, unclear scope or third-party integrations, so agree those before work starts.

Should a e-commerce app be native or cross-platform?+

Most e-commerce apps are best built cross-platform in React Native or Flutter, which covers iPhone and Android from one codebase. Native Swift and Kotlin are worth the extra cost when the app depends heavily on device hardware or real-time performance.

What should I ask a e-commerce app developer in Paris before hiring?+

Ask about published live stores with page speed scores above 80 on GTmetrix; checkout A/B testing experience; local payment method integrations. Then ask for two or three live e-commerce apps they built, who will actually work on yours, and what support looks like after launch.

Why is Tecklogist ranked first on this list?+

This list is published by Tecklogist, and we rank ourselves first because e-commerce apps are core work for us: fixed prices, fixed timelines and code you own. The other Paris agencies are ordered by the e-commerce evidence in their public profiles, and none of them pay to appear.
