Custom web applications to digitalize your business

When spreadsheets, e-mails and generic software can no longer keep up, it's time for a business application built around YOUR processes. At Digi4, we develop complex web applications — CRMs, ERPs, dashboards, SaaS platforms — with Angular and Node.js/Express, for Moroccan and international companies that want to automate, secure and steer their operations.

Our specialty: multi-portal systems, where several user types (back office, partners, customers, field teams) work on the same data with distinct interfaces and permissions.

How we work

Every project starts with co-written specifications: we translate your business into features and workflows before writing a single line of code. The technical architecture is then sized for your real volumes and your growth. Agile development delivers usable versions every two to three weeks — you watch the application grow and correct course along the way, not at the end. Finally, deployment includes the production rollout, team training and ongoing support.

How much does it cost?

A custom web application typically ranges from 15,000 to 50,000 MAD depending on scope — far less than years of a generic SaaS subscription, for a tool you own that fits your processes exactly.
