Cebu’s car rental marketplace, with a branded online store for every rental business.

Overview

A two-sided platform for Cebu’s car rental businesses. Every business gets its own branded storefront at 13c.online/their-name, and renters search across all of them, message owners, request bookings, and e-sign rental agreements. Businesses run their fleet, bookings, contracts, customers, and team from one dashboard, while 13C stays the technology platform and the business stays the rental provider.

Problem: Most small car rental businesses in Cebu run on Facebook, Messenger, and paper contracts, which makes them hard to find and compare, and every booking slow to confirm.
Solution: One Next.js app serves both the 13C marketplace and every business storefront, on Supabase with row-level security, database-enforced booking steps, realtime chat, generated contracts with e-signatures, an email outbox that never sends twice, and PayMongo subscriptions.
My Role: Concept, product design, and development.
