Services
Everything needed to take a product from an idea to something live that people use. Take the whole path or the one stage you're missing.
React Native and Swift
Native-feeling apps for iPhone and Android from one codebase, or fully native Swift when the product demands it. We handle offline behaviour, push notifications, in-app purchases, and the App Store and Play Store submissions.
Booking, portals, dashboards
The product your business runs on: booking systems, member areas, admin dashboards, and marketplaces. Built to load fast, work on a phone, and stay maintainable long after launch.
Fast, findable, editable
Sites that rank, load quickly, and turn visitors into enquiries. Product catalogues and payments where you sell, and content you can edit yourself without a developer.
Replace the spreadsheet
Quote builders, scheduling systems, inventory tools, and the integrations that connect them. Usually this replaces a spreadsheet three people are quietly working around.
Before you commit a budget
For an idea that isn't a spec yet. We define the audience, map what they need to do, prototype the first release, and give you a scope, a timeline, and a fixed estimate you can take anywhere.
Inherited something broken
For products left behind by another developer. We audit what exists, tell you honestly what is worth keeping, and rebuild the rest without taking the business offline.
What we build
Four kinds of product, all built the same way: scoped small, shipped early, and improved with real use.
iOS and Android apps, built once and released to both stores. Offline support, push notifications, and App Store submission handled.
Booking systems, member portals, dashboards, and marketplaces. The product your business runs on, not a page about it.
Fast, findable sites that convert. Payments, catalogues, and content you can edit yourself without calling a developer.
Internal tools, quote systems, and integrations that replace the spreadsheet everyone is quietly working around.
FAQs
Anything not covered here, ask on the call. It is free and there is no obligation at the end of it.
Yes, and that is the usual starting point. Bring the problem and who has it. Working out what to build, and what to leave out of the first release, is the first stage of the work.
It depends on scope, so you get a fixed estimate before any code is written. A focused first release typically lands in the low five figures; a marketing site is considerably less. Nothing starts until you have approved the number.
A first release usually takes six to twelve weeks depending on scope. You see working software long before that, in short cycles, rather than waiting for one big reveal at the end.
Anes does. Five Square Design is deliberately one engineer, so the person on your first call is the person who builds and ships. There is no sales handoff and no team you never met.
Completely. The code, the accounts, the domain, and the data are all yours, handed over documented. You are never locked into us to keep the product running.
Yes. Calls, documents, and the product itself can be in English or French. We are based in Montreal and work in both every week.
