What We've Built
Engineering work owned by Tremblay Systems Integration Inc., not client deliverables. Each one shipped with its own tests and its own way of catching itself wrong.
Migration Sizing Bench
A measurement bench that tells you how long a Microsoft 365 or Google Workspace exit will actually take, because every quote in this market is a guess in gigabytes.
Laravel Quote Estimator
A self-serve pricing tool on this bilingual site: seven questions, a real price on screen, no sales call and no waiting for a quote.
Canadian Tax Rules Engine
A rules engine that computes federal T1 and Quebec TP-1 income tax, with every constant traceable to the source page it came from.
Self-Hosted Business Stack
The full internal stack a small company needs, self-hosted on infrastructure we control, with one sign-on across all of it and no data leaving the country.
Cross-Border ERP
A working ERP for a company selling equipment across the Canada/US border, where the customs paperwork is the part that costs money when it is wrong.
