The story
Faster checkout, accurate stock, and numbers you can act on.
Challenge
- Slow checkout created queues at peak hours and lost walk-in sales.
- Stock counts drifted from reality, causing stockouts and over-ordering.
- Sales data sat in separate systems, so decisions were made on gut feeling.
- Loyalty programs were manual and disconnected from purchase history.
What we did
- Speed up the counter: A keyboard- and touch-friendly checkout flow with Stripe payments, built to finish a sale in under 30 seconds.
- Sync inventory in real time: Every sale updates stock instantly across locations, with Redis keeping the hot paths fast.
- Turn sales into insight: A live analytics dashboard shows best sellers, peak hours and margins per location.
- Reward repeat customers: Loyalty is tied to purchase history, so points and offers apply automatically at checkout.
Result
- Checkout 60% faster, with each transaction under 30 seconds.
- Inventory accuracy improved to 98% across all locations.
- Clients grew revenue by 25% using real-time sales analytics.
