Custom software that scales with your business.

From MVP to enterprise — mobile apps, CRMs, custom ERPs, and SaaS products engineered to be reliable, maintainable, and yours.

The problem we solve

Off-the-shelf software gets you 70% of the way. The last 30% — the workflows that actually differentiate your business — is where most companies lose months to workarounds, spreadsheets, and integrations that break. Cadex builds the software that closes that gap.

What we build

Mobile App Development

Native iOS and Android, plus React Native and Flutter for cross-platform builds. From discovery through App Store and Play Store launch.

CRM & Custom ERP Software

When Salesforce, HubSpot, or NetSuite cannot model your workflow, we build the parts that do — and integrate cleanly with the parts that already work.

SaaS Software Development

Multi-tenant architecture, subscription billing, role-based access, admin dashboards, and the operational tooling your support team needs from day one.

Our approach

1. Discover

Product strategy, user interviews, technical feasibility.

2. Design

User flows, prototypes, design system.

3. Build

Senior engineering in fixed-scope sprints, with weekly demos.

4. Launch & Optimize

App store submission, monitoring, post-launch iteration.

  • Test coverage and CI/CD pipelines from day one
  • Documentation that survives team turnover

frequently asked questions

A simple MVP starts around $40,000–$60,000 CAD. A production-grade mobile or web app with custom backend typically lands in the $80,000–$200,000+ range. We provide a fixed quote after the discovery phase.
Both. Native (Swift / Kotlin) when performance, deep OS integration, or platform-specific UX matters. Cross-platform (React Native / Flutter) when speed-to-market and a shared codebase are the priority.
Always. Cadex transfers full IP and source code at the end of the engagement. We can also continue under a support or product-team-as-a-service arrangement.
Yes. We start with a code review and architecture audit (1–2 weeks) so we can give you an honest read on what you are inheriting before committing to a roadmap.
