Showroom213
Service: SaaS productsMy own SaaS for Algerian car dealerships: inventory, leads, orders and invoices in one dashboard.
Built for a real problem: dealerships running everything on WhatsApp and Excel

The problem
Algerian car dealerships run their entire business on WhatsApp groups, paper notebooks and scattered Excel sheets. No software was built for how the DZ automotive market actually works.
The solution
A subscription platform that replaces every manual tool a dealership relies on: inventory, lead pipeline, orders, invoices and client management in a single dashboard that staff understand on first use.
Results

Technical details
What I did
- Took the product from idea to launch: concept, design, architecture, development and deployment
- Built a multi-tenant architecture where every dealership's data stays isolated
- Built subscription plans, plan limits and renewals without a third-party billing platform
- Designed the inventory, lead and invoicing workflows around how Algerian dealers already work
- Run the infrastructure and keep improving the product
Challenges and solutions
Multi-tenant data isolation
Designed the schema and access layer so each dealership's inventory, leads and invoices stay fully isolated on one shared platform.
Subscription billing from zero
Built subscription management in-house, handling plan limits and renewal logic directly, so pricing could follow the local market.
Designing for non-technical staff
Replacing a WhatsApp-and-notebook routine meant the interface had to be obvious on first use: no onboarding calls, no training documents.
