    Custom software development for Quebec businesses

    Arcset is a Quebec development agency that builds custom software and web applications: contractor portals, online payments, CRMs, dashboards, automations and system integrations. When off-the-shelf SaaS does not fit how your business runs, we build the tool that does, full-stack. This is the functional-software lane, beyond marketing websites, and you own the code we build for you.

    Your tools do not fit how you actually run the business?

    Off-the-shelf SaaS is built for an average company, not yours. So you bend your process to fit the software, pay for ten features to use two, and glue the gaps with spreadsheets and copy-paste. It works until it does not: the spreadsheet breaks at scale, two people overwrite each other, an order slips through, and nobody is sure which file is the real one. A custom tool flips that around. The software fits your process instead of the other way around, the data lives in one place, and the thing pays for itself in the hours you stop losing. That is the lane this page is about: functional software, not a marketing website. If you need a marketing site, that is our website-design service. Here we build the apps, portals, dashboards and automations that run the operation.

    What custom software has Arcset actually shipped?

    This is live, not a portfolio of mockups. Nanoxeal (live at nanoxeal.ca) is a bilingual e-commerce platform with embedded on-site Stripe checkout and a gated wholesale contractor portal: approved accounts log in with Supabase auth, get their own per-account pricing, and order online, with prices re-validated server-side so totals cannot be tampered with, plus a signature-verified payment webhook and a satellite-map project estimator out front. That is real full-stack web application development. Pavage MLP (live at pavagemlp.ca) runs on a CRM with a structured sales pipeline and automated client follow-up, plus a satellite-map quote estimator. Les Bons Morceaux (live at lesbonsmorceaux.com) is an e-commerce store with a yearly membership and a custom freezer-tracking dashboard that flags when to reorder. YFJ Services (live) runs on a CRM with follow-up automation. We also build and run our own SaaS, Autopilot (a CRM plus business intelligence at ap.arcset.ca), so you know we ship and run real software, not just one-off sites. Each one is a working build.

    What kind of custom software does Arcset build?

    Whatever your operation actually needs, built full-stack. Internal tools that replace the spreadsheet duct-tape. Customer and contractor portals with logins, roles and per-account pricing. E-commerce with real checkout and payments. CRMs with a structured sales pipeline and automated follow-up. Dashboards that surface the numbers you care about. Automations that route requests, send reminders and kill manual data entry. And when your existing systems need to talk to each other, the integrations to connect them. The proof is above: a gated contractor portal with private pricing, a freezer dashboard that triggers reorders, CRMs with follow-up that fires on its own. We are a Quebec development agency, so it is all bilingual by default and built with Quebec privacy expectations (Loi 25) in mind. We build for any Quebec business that needs functional software, not only mid-size SMBs. If you can describe the problem, we can scope a build, and you deal with a real developer, not a sales rep who disappears after the contract.

    How does a project work, and do I own the code?

    We start with how your business actually works, not a feature list. We map the process, find where the manual work and the leaks are, and scope the smallest tool that fixes it. From there we build in working slices you can see and use, so you are never staring at a black box for three months. You give feedback on something real, we adjust, we ship. You get a real, deployed application, not a slide deck. And yes, you own the code. The source, the data and the accounts are yours, hosted where you control it. No lock-in to a platform you cannot leave, no holding your software hostage. That is the difference between renting someone's SaaS forever and owning a tool built for you. When it goes live we do not disappear: we can stay on for maintenance and the next round. We work in French and English, with Quebec businesses, on Quebec time.

    Why pick a Quebec development agency over a big firm or a freelancer?

    A big firm bills you for a project manager, a sales layer and a team of juniors, and you rarely talk to the person writing the code. A lone freelancer is cheaper until they vanish mid-build or cannot cover the app, the payments and the deployment at once. Arcset sits in between: a developer who actually builds full-stack software end to end, ships it to production, and stays reachable after launch. Our clients run paving, e-commerce, exterior maintenance, insulation and local meat delivery, and the builds range from a CRM to a full payment platform. You do not need to be a tech company or a big firm, just a real problem that off-the-shelf tools do not solve. You get serious engineering without the agency overhead, in your language, in your timezone. Coming soon: Isolation 2 Frères, a bilingual site built around an interactive 3D thermal heat-loss visualizer, the kind of custom interactive tool that turns an abstract sales pitch into something a homeowner can see.

    Frequently Asked Questions

    It depends on scope. A focused internal tool or a CRM setup is a much smaller build than a full e-commerce platform with a gated contractor portal and secure payments. We scope the smallest version that solves the real problem first, give you a clear price before anything starts, and ship in stages so the budget tracks real, deployed progress. No surprise invoices. Tell us what is breaking and we will price the build.

    A focused tool or automation can be live in weeks; a full platform like the Nanoxeal storefront plus contractor portal takes longer. Because we build in working slices, you see usable pieces along the way instead of waiting for one big reveal at the end. We give you a realistic timeline at scoping, tied to your actual project, and the first usable version usually comes well before the whole thing is done.

    A marketing website exists to be found and to convert visitors: pages, copy, SEO, a contact form. Custom software does actual work: logins, payments, dashboards, automations, integrations, things people use to run a process. Nanoxeal is the clean example: the storefront pages are the marketing side, but the contractor portal, the Supabase logins, the server-side pricing and the signed payment webhook are the custom software underneath. This page is the functional-software lane. If you only need a marketing site, that lives on our website-design page. Many clients need both, and we build both.

    Yes. The source code, the data and the accounts are yours, hosted where you control it. No lock-in to a platform you cannot leave, no holding your software hostage. You are buying a tool built for you, not renting access to ours.

    Yes, if you want it. We stay reachable after go-live for fixes, updates and the next round of features as your needs change. We run our own SaaS, Autopilot, in production, so keeping software healthy after launch is normal work for us, not an afterthought. Several of our clients have grown the relationship over time into ongoing work.

    Yes. We work fully in French and English, and we build everything bilingual by default. You pick the language you are comfortable in and we run the whole project there.
