Web applications

The app your business was missing.

Back-offices, client portals, partner extranets, booking, inventory: we build web applications available anywhere, on desktop, tablet and phone.

In short

When no software does exactly that.

Some needs fit no box: a portal for your clients, a scheduling tool specific to your trade, a back-office linking your orders, stock and deliveries.

We design the application that meets that exact need, with a clear interface and permissions tailored to each user. It runs in the browser: nothing to install, and it works on phones too.

Client portals

Your clients track their orders, download their documents and message you in the right place.

Back-offices

An internal tool to manage orders, stock, schedules or files, with no double entry.

Booking and scheduling

Slots, resources, teams: a schedule that follows your rules.

Online payment

Deposits, subscriptions and invoices paid online, securely.

Secure access

Personal accounts, role-based permissions, a log of important actions.

Installable on phones

Your app can be added to the home screen, just like a native app.

We can host and maintain it for you, or deploy it on your own hosting. We explain where your data is stored.

Yes. We deliver the essentials first, then add features as your needs grow, one-off or as part of a subscription.

Often, yes. We start with an audit of the code and hosting, then propose to evolve it or rebuild it.

A tool that fits you can be built.
