Web applications and e-commerce
Web application and e-commerce development
We build software that runs in the browser: online stores, customer portals, membership sites, booking platforms and admin dashboards. We work with companies that need more than a website, with logins, business rules and operations happening online.
A web application is where a website stops being a storefront and becomes part of your operation. Customers log in, buy, book and track orders. Your team runs everything from a dashboard without installing anything.
We build these systems with the same product care we apply to apps and SaaS: simple flows for users, a complete dashboard for admins and performance that holds up during campaigns and peak seasons.
For e-commerce we handle the store end to end: storefront, catalog, cart, checkout, shipping, payments and marketing integrations. We also build stores ready to sell in several countries, like the one we built for Maison Livenne.
Who it is for
- Brands that want their own online store with a better experience than a marketplace listing.
- Companies that need a portal where customers track orders, contracts or services.
- Education and content businesses that need a membership area.
- Operations built on online booking, reservations or orders.
- Companies selling internationally, in more than one language and currency.

- React

Timeline
Timelines vary with the number of modules, the integrations and the volume of products or users. A store with a lean catalog and standard checkout ships sooner than a portal with many business rules and internal integrations.
The schedule is detailed in the proposal, with milestones you can test before launch.
How much does a web application or online store cost?
Pricing is based on scope, with a fixed quote before we start. The main drivers are:
- Number of modules and user roles.
- Integrations with ERP, inventory, shipping and payments.
- Number of products, languages and currencies.
- Specific business rules, such as customer-specific pricing or subscriptions.
- Hosting, support and ongoing development after launch.
If you are just starting, you can launch with the essential modules and add the rest as your operation grows.

Web applications and e-commerce FAQ
What is the difference between a website and a web application?
A website presents the company. A web application runs part of the operation: it has logins, business rules, data management and an admin dashboard.
Do you build online stores?
Yes. We build complete stores with catalog, checkout, shipping, payments and a management dashboard, including stores that sell internationally.
Which payment methods can I accept?
Cards and digital wallets through Stripe, plus local payment providers depending on your market.
Can the system integrate with our ERP?
In most cases, yes, via API or data imports. We assess integrations during discovery.
How much does a web application cost?
It depends on modules, integrations and business rules. You receive a fixed quote in the proposal before we start.
Do you offer support after launch?
Yes. We offer support, fixes and maintenance and development plans.
Can you migrate my current store?
Yes. We migrate products, customers and order history from your current platform and set up redirects so you keep the search rankings the store already has.
Where is the system hosted?
We choose hosting with you based on traffic, budget and security requirements, and handle the setup, domain and SSL certificate.
