  • Use browser location with fallback to manual neighborhood selection.
  • Show store distance, estimated delivery time, and current open status.

Amina works late and remembers she needs groceries for dinner. Instead of calling a nearby store and waiting for someone to answer, she opens Grocerly, signs in, picks a nearby shop, and adds milk, rice, fruit, and snacks to her cart in under two minutes.

She chooses card payment, places the order, and instantly sees that the seller has received it. A few minutes later, the seller accepts the order, Amina gets a notification that it is being prepared, and the tracking page updates as the order moves through packing and pickup.

By the time she leaves work, the groceries are ready or already on the way. The store gets fewer phone interruptions, fewer missed orders, and a smoother process that turns nearby demand into repeat business.

  • Track order_status_changed with old status, new status, and actor role.

Technical Needs

  • Use React and Next.js for the web app with server-side rendering for fast initial loads.
  • Use Node.js with NestJS or Express for API services.
  • Use PostgreSQL for relational order, user, store, and payment data.
  • Use Redis for session storage, cart caching, and notification jobs.
  • Use WebSockets or server-sent events for live order tracking updates.
  • Use a job queue such as BullMQ for asynchronous notifications and retries.
  • Use object storage such as AWS S3 for receipts and invoice PDFs.

Integration Points

  • Stripe for card payments and payment intents.
  • Twilio for SMS order notifications and OTP delivery.
  • Firebase Cloud Messaging or OneSignal for web push notifications.
  • Google Maps Platform for address autocomplete, geocoding, and distance estimation.
  • Auth0 or Clerk for optional managed authentication, if faster to launch.

Data Storage & Privacy

  • Store only the minimum personal data needed for fulfillment: name, phone, address, and order history.
  • Encrypt sensitive data in transit with TLS and at rest using managed cloud encryption.
  • Support account deletion and data export requests to meet GDPR and CCPA expectations.
  • Limit seller and rider access to only the order data required for their role.
  • Log payment tokens and external identifiers, never full card data or CVV.

Scalability & Performance

  • Cache catalog and store metadata aggressively to reduce database load.
  • Use background workers for notifications so order placement stays fast.
  • Paginate order history and catalog endpoints to prevent large payloads.
  • Separate read and write paths for order tracking if traffic grows significantly.

Potential Challenges

  • Inventory mismatches may cause cancelled orders; mitigate with real-time stock checks and clear substitution rules.
  • Notification delays could confuse customers; mitigate with multi-channel delivery and retry queues.
  • Payment failures may reduce conversion; mitigate with saved payment methods and clear retry states.
  • Seller workflow adoption may be slow; mitigate with a simple dashboard, large action buttons, and training materials.
  • Location and address errors may break nearby store matching; mitigate with geocoding validation and manual location selection.
