Visual mockup of your custom application

We create the complete mockup of your application — every screen, every button, every interaction — before you spend a single thing. During a dedicated meeting in Perpignan, you see exactly what you'll get. If something doesn't feel right, we adjust together until it's perfect.

Frequently asked questions

FAQ — application development in Perpignan

The price of a custom application depends primarily on the features you want to include: number of screens, business logic complexity, third-party integrations (payments, notifications, maps), expected user volume, and security requirements. Rather than giving you a vague estimate that systematically drifts during the project, we work with a catalogue where every component — screen, button, feature, integration — has a fixed, upfront price. You build your application à la carte, like a menu, and the quote is calculated automatically component by component. You know exactly what you pay and why, you adjust the scope to fit your budget, and the precise quote is established after the mockup is validated — with no commitment up to that point.

Choosing a local application developer in Perpignan means choosing human proximity and reliability. Concretely: in-person meetings (mockup presentations, progress reviews, workshops), the same time zone, the same language, immediate responsiveness with no delay, and above all real knowledge of the Pyrénées-Orientales business landscape — your customers, your seasonal constraints, your market. You deal directly with the person who designs your application, not with a sales rep relaying to an offshore team. And if tomorrow you want to add a feature or evolve the app, you know where to find us.

We develop the full range of applications a business may need: iOS and Android mobile apps (native via Flutter — one codebase, two platforms), web applications and SaaS platforms (client portals, marketplaces, member areas, business dashboards), custom CRM (client and prospect management, quotes, invoicing), custom ERP (production, stock, HR, scheduling), business software (fleet management, site tracking, booking, loyalty) and admin back-offices connected to your existing tools. Whether you are a tradesperson, retailer, restaurateur, startup, SME or entrepreneur in Perpignan or the Pyrénées-Orientales, we tailor the solution exactly to your business and the way you work.

Building your custom application happens in four clear steps. Step 1 — a free first conversation (call or in-person meeting in Perpignan) to understand your needs, your users, your goals and identify the most suitable type of application. Step 2 — complete visual mockups: we turn your vision into interactive mockups, screen by screen, presented in a meeting and adjusted together until validated. Step 3 — the transparent fixed-price quote, component by component, with optional instalment payment. Step 4 — development with a modern stack (Flutter, Laravel), testing, go-live and deployment to the stores (App Store, Google Play, web). At every step you stay in control, and the delivered application is 100% true to what you approved in the mockup.

Yes, instalment payment is built into how we work. The principle is simple: your application's cost is spread over the development period, with no hidden fees, no interest, no credit institution. In practice, a multi-month project is billed monthly, with a schedule agreed upfront based on your cash flow. This makes custom application projects accessible to small and mid-sized businesses and entrepreneurs in the Pyrénées-Orientales who want to invest in a business tool without locking up cash on a large upfront payment. And since everything is transparent from the start — component-based quote, signed schedule — there are no bad surprises along the way.

Timelines depend on the size and complexity of your project. A simple mobile application (3 to 5 screens, standard features) can be delivered in a few weeks. A medium-complexity web app or SaaS platform (user management, dashboard, payments) typically takes two to four months. A full business CRM or ERP, with integrations and multi-role access, can span four to six months. The visual mockup is always the first phase (two to three weeks usually) — it's what secures the development timeline, because once the mockup is validated there are no surprises on the scope. We share clear milestones in the quote and you follow progress in real time.

Our tech stack is modern, proven and chosen for long-term reliability. For iOS and Android mobile apps, we use Flutter (Google's framework): one codebase, two platforms, native performance, faster development and lower costs. For web applications, SaaS platforms, CRM, ERP and business software, we work with Laravel (PHP) on the back-end and Flutter Web or modern JavaScript frameworks on the front-end, with Firebase or SQL databases hosted in France. Our applications are secure (HTTPS, robust authentication, GDPR compliance), scalable (architecture designed to grow with your business) and maintainable (clean, documented, tested code).

Our core focus is supporting businesses in Perpignan and the Pyrénées-Orientales (66) — that's where we favour in-person meetings and human proximity. That said, remote work is part of our daily routine: video calls, mockup sharing, weekly check-ins, real-time tracking. If you're a business outside the department (Occitania or elsewhere in France) and our approach — mockup before payment, fixed price per component, instalment payment — fits your needs, let's talk during a free first conversation. Distance isn't a blocker if there's alignment on the method.
