The problem
- Providers needed a flexible way to buy listing packages across many categories and geographies, but package pricing was too complex to manage manually — bundles, tiers and multi-country rules made quoting slow, error-prone and impossible to scale, with no e-commerce foundation ready for launch.
What we built
- Web-only multipurpose classifieds marketplace with multi-category browsing and publishing.
- Package-based listing sales for providers with purchase and management flows.
- Highly complex pricing engine calculating tiered package costs across categories.
- Multi-country architecture ready to scale across diverse markets.
- React + Supabase platform delivered entirely with AI-assisted development.
The result
- Launched at coleffe.com in under 10 weeks, on time for business debut.
- Complex package pricing automated and ready for scale.
- Quality-first web platform stable for launch and growth.
- Multi-category, multi-country foundation for continuous expansion.
- Efficient monetization through flexible bundle sales.
Multiclasificados Effe is a multipurpose classifieds marketplace where providers purchase listing packages to publish across diverse categories, with reach across multiple countries worldwide. The platform was delivered web-only in record time — under 10 weeks — as a React frontend on Supabase, developed entirely with AI-assisted workflows. Its core is a highly complex package pricing engine that calculates tiered bundle costs, enabling flexible monetization at scale. Zerocode accompanied Effe from build through launch, prioritizing platform quality, stability and readiness for growth at coleffe.com.
