01 — Local economy
Business in Montreal
Aircraft are designed and built across greater Montreal, where Bombardier, CAE, Pratt & Whitney Canada and Airbus's A220 line at Mirabel lead a deep aerospace supply chain. Ubisoft and other studios make the city a major video-game centre, the Mila institute anchors AI research, and the Port of Montreal handles container traffic between Europe and central North America.
Also known as Montréal.
Where software helps: Quebec businesses must provide French-language invoices, contracts and software interfaces under Bill 96, and collect QST alongside GST, which forces many English-first ERP and billing setups to be reworked.

05 — FAQ
Custom software in Montreal: common questions
Do you build custom ERP and AI software for businesses in Montreal?
Yes, remotely. Flip Retail is a software studio in Jaipur, India, with no office in Montreal; discovery happens on video calls and you get working software every two weeks.
How do time zones work between Montreal and Jaipur?
Jaipur is 10 h 30 min ahead of Montreal on standard time, and 9 h 30 min ahead during daylight saving time there. A 09:00 start there is 19:30 in Jaipur. Office hours don't overlap, so we fix one call slot at the edge of the day and work asynchronously in between.
Can a custom ERP handle Quebec sales tax?
Yes. Invoicing handles Quebec sales tax (GST 5% + QST 9.975%) alongside federal GST. A custom ERP produces compliant invoices and tax reports, and we keep the rules updated as they change.
Can your AI agents talk to customers in French and English?
Yes. Current language models handle French and English well, including mixed-language messages. We still test an agent in each language your customers use before it goes live, and route anything it is unsure about to your team.
What would a first project look like for a aerospace business?
Usually one module that fixes the most expensive problem first. For aerospace & defence supply chain that is often serial & batch traceability and certificates of conformity. It goes live early, and the rest of the system follows in two-week increments while your team is already using it.
