Generic SaaS handles your workflow, just not in French and not under your aerospace rules
Custom software in Montreal runs $70k to $250k depending on scope, over 4 to 10 months. Generic off-the-shelf SaaS covers the common 80 percent, but in Montreal the remaining 20 percent is usually two hard things at once: French as the legal default under Bill 96, and a regulated or specialized workflow from aerospace, pharma, or AI work that no horizontal SaaS models.
The generic SaaS your team trialed is fine until it meets the specifics of your operation. A Montreal aerospace supplier needs Controlled Goods segregation and AS9100 traceability. An AI-services firm needs to wrap model pipelines in client-specific governance. A pharma company needs GxP-aware records. None of those live in a horizontal product, and all of them have to be French-first for the people and customers who touch them.
So you end up gluing three SaaS tools together with spreadsheets and manual steps in between, and the seams leak. The custom case is rarely about replacing one tool, it is about the workflow that spans them, which is where Montreal's bilingual and regulated requirements compound.
Why the usual tools struggle in Montreal
- Horizontal SaaS can't model aerospace, pharma, or AI-governance workflows specific to your operation
- Glue between three SaaS tools leaks at the seams, with spreadsheets filling gaps
- French-first is impossible to retrofit consistently across a stack of English-first tools
- Regulated audit trails are spread across tools that don't share an access model
What a custom custom software build changes
You build when the workflow that defines your business spans tools no single product covers, and when it has to be French-first and auditable end to end. Custom software lets you model your actual aerospace traceability, AI governance, or pharma process once, in French by default, with one access and audit model instead of three. That coherence is the value generic SaaS structurally can't give a regulated Montreal operation.
The features that matter for Montreal
Montreal custom software: the full scope
Everything a custom software build here can cover: API development, cloud software, MVP development, legacy modernization, systems integration, microservices and database design.
- Your defining workflow spans tools no single SaaS product covers
- French-first and regulated audit must hold across the whole process
- Spreadsheets and manual handoffs sit between your current SaaS tools
- The workflow is a competitive differentiator, not a commodity
- Your need is a common workflow a mature SaaS already nails
- No regulated audit or French-first legal requirement is in scope
- You can't commit an owner to a long-lived custom system
- Time-to-value matters more than fit
Custom Software pricing in Montreal: the real numbers
| Project scope | Typical cost | Timeline |
|---|---|---|
| Focused custom app replacing a leaky SaaS-plus-spreadsheet workflow | $70k to $120k | 4 to 6 months |
| End-to-end regulated workflow platform | $160k to $250k | 7 to 10 months |
| Custom layer integrating and governing existing SaaS tools | $90k to $150k | 5 to 7 months |
From kickoff to launch: the schedule
Exactly what you get
Software that models the workflow your Montreal business actually runs on, end to end, French-first, with one access and audit model instead of three SaaS tools held together by spreadsheets. Whether that's aerospace traceability, AI-governance pipelines, or a GxP pharma process, it's built once and integrates with your ERP, BI dashboards, and accounting software. You also get a configurable rules layer so the process can change without a rebuild.
How to choose a developer in Montreal
Pick a team that maps your workflow back to you before quoting, because that's the only honest way to scope custom software. Ask how French-first lives across the whole stack, how they've handled regulated audit before, and how they control scope creep, the main reason bespoke builds fail. A strong Montreal partner has shipped specialized, bilingual, auditable systems and will tell you which parts should stay on commodity SaaS.
- Your real workflow modeled once, end to end, instead of glued across three SaaS tools
- French-first by default across the whole stack, not retrofitted per tool
- One access and audit model for regulated aerospace, pharma, or AI work
- Spreadsheet seams between tools eliminated
- Clean integration with your ERP, BI dashboards, and other systems of record
- Custom software is the most expensive and longest path, justified only by real specificity
- You own the full maintenance and security burden indefinitely
- Scope creep is the main failure mode on bespoke builds
- Commodity workflows are cheaper and safer left on proven SaaS
- !They quote before understanding your workflow, ask them to map it back to you first
- !They treat French-first as a phase-two add, ask how it lives across the stack
- !No regulated-audit experience, ask for a comparable compliant build
- !They underplan integration, ask how it connects to your ERP and BI
- !No scope-control method, ask how they prevent the classic custom-build creep

Frequently asked questions
When is custom software actually the right call in Montreal?
When the workflow that defines your business spans tools no single SaaS covers, and it has to be French-first and auditable end to end. That combination, common in Montreal aerospace and pharma, is what generic SaaS structurally can't deliver.
How much does custom software cost here?
A focused app replacing a leaky SaaS-plus-spreadsheet workflow runs $70k to $120k. An end-to-end regulated platform runs $160k to $250k over seven to ten months.
Can we keep some SaaS and only build the gaps?
Often the best move. A custom layer that integrates and governs your existing SaaS tools runs $90k to $150k and fixes the leaky seams without replacing what already works.
Why is French-first harder to retrofit than to build in?
Retrofitting French across a stack of English-first tools means fighting each one separately and still missing custom fields and documents. Building French as the default once, in custom software, makes it consistent across every surface.
