The Challenges

The development of Grocery Giggle presented several multifaceted challenges, primarily centered around:

  • Managing Hybrid Payment Models (One-Time vs. Subscription)
    Supporting both single purchases and recurring subscriptions required distinct logic paths in billing, user experience, and backend management.
  • Real-Time Inventory Synchronization
    Maintaining accurate stock levels across high-turnover items while ensuring consistency between cart reservations and actual inventory, especially during peak order volumes.
  • Handling Recurring Payments via Omise
    Building a secure, resilient billing infrastructure capable of handling recurring charges, failures, and automatic retries using Omise’s API and webhook system.

The Solutions

To overcome the challenges of hybrid payments, real-time stock handling, and recurring billing, Grocery Giggle implemented the following strategic solutions:

Hybrid Payment
Managing Hybrid Payment Models
  • Hybrid Payment Management: Separate backend flows for subscription and one-time orders built using Node.js and Omise API integration.
  • Automated Recurring Billing: Implemented cron-based triggers to auto-process weekly or monthly subscription payments reliably.
  • Dynamic User Experience: AngularJS frontend intelligently adapts the checkout UI based on the selected payment model.
Real-Time Inventory
Real-Time Inventory Synchronization
  • Atomic Stock Updates: Ensured accurate inventory counts using database transactions for every purchase or stock change.
  • Soft-Lock Mechanism: Temporarily reserves items in users’ carts to prevent overselling during checkout.
  • High-Traffic Optimization: Leveraged Redis caching for frequently accessed inventory data to boost performance.
Handling Recurring
Handling Recurring Payments via Omise
  • Webhook-Driven Automation: Integrated Omise webhooks to track subscription events like successful charges, failures, and cancellations.
  • Retry & Recovery Logic: Built backend flows to automatically retry failed payments and update user status accordingly.
  • Real-Time Status Sync: Ensured subscriptions are always up-to-date without manual checks, improving reliability and trust.
Handling Recurring
Hot Offers & Promo Engine
  • Dynamic Discounts: Sellers can create time-limited or category-based discounts to boost engagement and sales.
  • Promo Code Engine: Customers can apply unique codes at checkout for exclusive deals and loyalty rewards.
  • Personalized Offers: Show customized promotions based on user behavior, cart contents, or subscription status.
