İste Rent A Car: E-Commerce Booking Engine & Firebase Backend Integration
"The 20% commissions we paid to global car rental platforms were breaking our backs. We couldn't take online payments or manage fleet calendars on our own site. Thanks to the Firebase booking engine and Iyzico integration Nexentio developed, everything is automated. Double bookings are gone, and commissions stay in our pocket. The dynamic seasonal pricing algorithm transformed us into a highly professional company."
Challenge: Marketplace Commision Dependency & Calendar Sync
Paying high commissions to global listings sites like Rentalcars reduced profitability. The brand lacked a real-time dynamic pricing model (seasonal demand, duration discounts), live calendar synchronization, and safe online billing.
Solution: Firestore-Backed Reservation Algorithm & Sanal POS Integration
We programmed a robust reservation engine on Next.js 16 and Firebase Firestore that handles dynamic daily calculation. We linked the checkout directly with the Iyzico virtual POS API.
- 01Developing a fast reservation UI using Next.js 16 and Tailwind v4.
- 02Setting up real-time fleet calendar sync using Firestore database.
- 03Building auto-calculating algorithms for seasonal rates and rental durations.
- 04Integrating Iyzico virtual POS gateway API with 3D Secure checkout.
