On Montreal's South Shore, developing a mobile app generally runs from $15,000 to over $100,000 depending on complexity (indicative range). Bollé Communications, whose office is in Beloeil, designs and develops iOS and Android apps for South Shore businesses, in French, native or hybrid, from idea to launch.

What we build for South Shore businesses
From Longueuil to Brossard by way of Boucherville, Saint-Lambert and Chambly, South Shore SMBs need apps that solve a real business problem — not a gadget. At Bollé Communications, we cover the full cycle, from idea to release on the App Store and Google Play.
- iOS and Android apps — native or hybrid development (React Native, Flutter) depending on your performance needs and your budget.
- Business apps — client portals, booking, catalogues, inventory management, tools for your field teams.
- Mobile commerce — online sales, secure payments (e.g. Stripe), loyalty and push notifications.
- Connection to your systems — integration with your APIs, your CRM, your accounting software or your existing website.
- Intelligent features — recommendations, chatbots and data processing through our AI automation expertise.
- Maintenance and evolution — iOS/Android updates, security fixes and new features after launch.
Why choose a South Shore agency
Our Beloeil office is at the heart of the South Shore, a short drive from Longueuil, Brossard, Boucherville, Saint-Lambert, Chambly and Saint-Bruno-de-Montarville. That proximity concretely changes the dynamic of an app project: in-person kick-off meetings, scoping workshops at your site, usability testing with your actual teams and close follow-up at every stage.
Working with a local agency also means support in French, in the local time zone, with no intermediary abroad. You speak directly with the people designing and coding your app. Founded in 2003, Bollé Communications has supported Quebec SMBs and organisations in their digital projects for more than 20 years. On the South Shore, where retailers, manufacturers and service providers compete for the attention of a mobile, well-connected clientele, that responsiveness is often the difference between a project that moves and one that drags.
Our approach: scope before you code
A successful app project starts with a scoping phase, not with a line of code. We first define your business objectives, your users and the minimum viable product (MVP) that delivers value quickly. Then come experience design, iterative development, testing on real devices and deployment to the app stores. After launch, we measure usage and evolve the app.
Scoping is also where we recommend native or hybrid. A native app (two codebases, iOS and Android) maximises performance; a hybrid app shares a single codebase and cuts costs by roughly 30 % to 50 % (indicative range). For most South Shore business projects — commerce, booking, client portals — the hybrid approach offers the best cost-benefit ratio, and native is reserved for apps with heavy performance demands.
What a mobile app costs on the South Shore
The main cost driver is the number and sophistication of the features. Here are realistic benchmarks for the Quebec market (indicative ranges — to be confirmed for your project):
- Simple app (MVP) — $15,000 to $30,000. Showcase, information pages, a form and push notifications, often built hybrid, delivered in roughly 6 to 12 weeks.
- Medium-complexity app — $30,000 to $70,000. User accounts, secure login, API integration, payments or booking. This is the most common range for a South Shore SMB.
- Complex app — $100,000 and up. AI, real-time data, dashboards, compliance requirements; these projects usually run 6 to 12 months.
Also budget 15 % to 20 % of the initial cost per year for maintenance (updates, hosting, security).
Complementary digital services
An app never exists on its own. We tie it into your ecosystem: our website design team ensures consistency with your site, our web marketing group works on visibility and user acquisition, and our AI automation expertise adds intelligent features that save your teams time.

Frequently asked questions
Do you develop apps for businesses in Longueuil and Brossard?
Yes. Our Beloeil office serves the entire South Shore, including Longueuil, Brossard, Boucherville, Saint-Lambert and Chambly. We travel for key meetings and stay available in French, in the local time zone.
How long does mobile app development take?
A simple app takes roughly 6 to 12 weeks, a medium-complexity app 3 to 6 months, and a complex project 6 to 12 months (indicative range). The schedule depends on the number of features and the integrations required.
Is a native or hybrid app better?
For most business projects, hybrid is enough and costs 30 % to 50 % less than two separate native builds (indicative range). Native is mainly justified by high performance requirements. We advise you based on your specific objectives during scoping.
Should we budget for costs after launch?
Yes. Plan 15 % to 20 % of the initial cost per year for maintenance: iOS and Android updates, security fixes, hosting and small improvements. An app is a living product, not a one-time deliverable.
Can you build artificial intelligence into my app?
Yes. We integrate AI and automation features — recommendations, chatbots, data processing — adapted to your sector, through our AI automation expertise.
