Booking app
Online appointments, services, team, slots, cancellations. Automatic reminders and notifications.
What we build
Your app. Your website.
Your business tool.
It all starts with your idea. Custom mobile app development, web development, an online store, or the business tool you're missing: you pick the branches, we build the rest.
Your idea
Tap a branch to explore.
Native, PWA, or both
- Native app: downloadable on the App Store (iOS) and Google Play (Android).
- PWA: an installable web app that works without going through the stores.
- Both: depending on your strategy and your budget.
You are not forced to publish on the stores. We recommend the format that fits your project. And whatever the format, your app is present everywhere your customers are: mobile, tablet and desktop.

Everything about our websites
See the price in detail
Kodex builds everything your business needs to move forward: native apps, installable apps, websites, online shops and business tools. Shops, restaurants, beauty salons, clinics, real estate agencies, SMEs or established brands: we adapt to your trade, not the other way around.
On the business tools side, we build your custom CRM, your dashboard, your stock management, your quotes and invoicing and your team planning, on request.
To go further: restaurant app, real estate agency app, beauty salon app, hair salon and barber app and the cost of a mobile app in detail.
What we can build
It doesn't all come down to a booking app. Here are the building blocks we assemble, alone or together, depending on what your trade needs. And if the one you need isn't on the list, we build it.
Digital loyalty card
Stamps, tiers, rewards. It doesn't get lost at the bottom of a wallet.
Online store
Catalogue, real stock, cart, orders, back-office management. Click and collect or delivery.
Custom showcase website
Your pages, your words, your SEO. Built to be found on Google, not just to look good.
Product or vehicle catalogue
Detailed listings, photos, filters, an admin area to change everything yourself.
Business management tool
A CRM shaped to your trade: jobs, teams, step-by-step tracking, dashboard. Works offline.
Follow-up app
Multi-session journeys, history, reminders. For health, aesthetics, coaching.
Online ordering
Guided product build, sent to the kitchen or workshop, order tracking.
Stock management
Ins, outs, alert thresholds. Stock updates with every order, no re-entry.
Quotes and invoicing
Quotes sent in one click, turned into invoices, numbered and archived. Automatic reminders for unpaid ones.
Planning and team
Hours, time off, services per person. Everyone sees their day, you see the whole.
Dashboard and exports
Revenue, footfall, average basket. Clean export for your accountant, in the format they expect.
Our method
Six steps.
Zero compromise.
A rigorous process, proven on demanding brands. From the first conversation to production launch, every step is designed to remove the blind spots.

Le Monde de Mélya
Pastry shop · Website and click & collect
Le Monde de Mélya wanted to showcase its trompe-l'œil pastries and let customers reserve them for in-store pickup. We built a website that shows the creations and offers a click & collect journey. Customers can put together a box of trompe-l'œil pastries and filled brioches, then give their name and a pickup slot. Payment is made in store, not online. For events, they also find a dedicated quote request.

CARS VM
Used vehicles · Roncq
In Roncq, CARS VM sells and buys back used cars. The business needed to present its stock, its warranties and its trade-in offer on its own website. We built a showcase with the showroom's vehicles, their specifications and their prices on display. A dedicated section explains trade-ins and warranties. Visitors can browse the vehicles, then pick an appointment slot for a test drive, a valuation or a question. The showroom address and contact details are also easy to find.

Manifesto
One conviction :
thecustom-built.
None of our projects looks like the last one. Every brand imposes its own grammar, its own rhythm, its own constraints. We listen before writing a single line of code.
Every website, every app, every tool is thought through, designed and developed for a single client. That is our only standard.
Kodex Production
Our commitments
What we owe you.
01
A lifetime licence
A lifetime licence, exclusive to your business. Your name, your data and your accounts stay yours. Never held hostage, never dependent.

03
An expert's advice
We don't just take orders, we guide you. The right decision for your project, not the most profitable one for us.
04

We start from your problem, not from a template. We don't ship code, we ship solutions.
