Développement web et logiciels
Développement web et logiciels. InersiaLab conçoit et développe des logiciels couvrant l'ensemble des besoins d'une entreprise en pleine croissance. Cela inclut notamment WordPress et Elementor pour les sites axés sur le contenu, ainsi que des plateformes développées sur mesure utilisant la pile MERN, et bien plus encore.
Découvrez notre Software Development
We build websites two ways, depending on what the project needs. Most businesses are well served by a WordPress and Elementor build fast to launch, easy for your team to update, and fully capable of custom functionality through PHP wherever the page builder reaches its limit. Some projects need more: a client portal, a dashboard with real data logic, or a platform that has to scale past what a CMS was designed for. For those, we build fully custom in the MERN stack â MongoDB, Express, React, and Node.js â with the data model and architecture designed around your actual product, not adapted from a template.
We build iOS and Android apps around how your business actually operates, not around a generic template pulled from an app-builder tool. That starts with understanding the core user flow â what someone needs to accomplish in the app, and how quickly they need to be able to do it â before a single screen gets designed. From there we handle the full path from first wireframe to app store submission, including the backend logic and API work most "app builder" services can't touch. Whether the right approach is a single cross-platform codebase or native development for each platform depends on the project's performance needs and budget, and that's a decision we make with you during discovery, not before it.
Off-the-shelf software forces your team to work around its limitations. We build the opposite â internal tools, admin systems, and multi-tenant SaaS platforms designed around your actual workflow, so the software adapts to how your business runs instead of the other way around. This includes everything from a simple internal dashboard that replaces a spreadsheet-based process, to a full SaaS product with user accounts, billing, and role-based permissions built in from the start. We architect for the scale you'll actually need, not the scale a generic template assumes.
Not every tool belongs in a browser. For internal software, client-facing utilities, or products that need direct access to a user's system, we build cross-platform desktop applications â one codebase running on Windows and macOS, built for the specific task rather than adapted from a web app.
For most stores, WooCommerce on WordPress is the right call â it's fast to launch, well-supported, and handles product catalogs, inventory, and standard checkout flows without reinventing anything. But some businesses need checkout logic, inventory systems, or third-party integrations that a standard WooCommerce setup can't handle cleanly. In those cases, we build fully custom e-commerce platforms instead, with the payment flow, product logic, and integrations designed specifically around how the business sells.
A product can be technically functional and still fail if people can't figure out how to use it â UI/UX is the difference between those two outcomes, and it has to happen before development, not as a polish pass after. We design the actual user flow and interface around how real users behave, not how the org chart imagines they'll behave, then hand that off as a build-ready foundation for development.
A landing page has one job â get a specific visitor to take a specific action â which makes it a fundamentally different build than a full website trying to serve every visitor and every goal at once. We design and build these around the traffic source and offer driving them, usually to support a specific ad campaign or launch, not as a scaled-down homepage.
A site can have great content and still rank poorly or lose visitors if the technical foundation underneath it is broken â slow load times, poor site structure, missing technical signals search engines rely on. We audit and fix the technical layer directly: site speed, crawlability, structured data, and core web vitals, distinct from the content and keyword strategy handled by our Digital Marketing team.
Combien ça coûte ?
Chaque projet fait l'objet d'une analyse au cas par cas : un site WordPress, une application mobile et une plateforme SaaS sur mesure présentent des structures de coûts trÚs différentes. C'est pourquoi nous établissons un devis aprÚs avoir cerné l'étendue du projet, plutÎt que de proposer un montant forfaitaire.
Bien plus qu'une simple agence. Un partenaire de croissance.
Frequently Asked Questions
WordPress is faster and more cost-effective for content-driven sites you'll update often. A custom-coded platform (MERN stack) makes sense when you need logic, data structures, or scale a CMS can't handle.
WooCommerce covers most stores well and launches faster. A custom build makes sense when your checkout logic, inventory, or integrations don't fit a standard setup.
Yes, for businesses that need software running outside the browser rather than a web app.
