Online grocery delivery across Dubai: nearly 15,000 products, delivery slots, and every order checked by a person before it's confirmed.

// THE PROBLEM
Why it exists
A Dubai grocer wanted customers to order from nearly 15,000 products online, pick a delivery slot and pay online or on delivery.
The store holds no stock: it buys each order after checkout. So no order can be confirmed automatically. Someone has to check it first, and if an item can't be bought, the customer needs the difference back without a phone call.

// WHAT I BUILT
The rules
01
Orders are never confirmed automatically. The store confirms an order, adjusts it by reducing or removing lines, or rejects it. Adjusting refunds the difference and rejecting refunds the lot, automatically, and a refund can never be sent twice.
02
Customers choose a delivery slot at checkout. The slot is reserved inside the database in a single step and held for 15 minutes, so two customers can't take the last place.
03
Prices include VAT, so VAT is taken out of each line rather than added on, and the totals are the sum of the rounded lines. Each confirmed order gets its own tax-invoice number, issued once even if two people click at the same moment.
04
Most browser apps answer every address with "OK". This store's server checks first: a live product returns 200, a withdrawn one 410 and an unknown address 404. Each page also carries its own title, description and product data in the raw HTML, so Google and WhatsApp previews see the real product.
05
Customers get WhatsApp messages as an order is received, confirmed, out for delivery and delivered, or adjusted or rejected, and the team gets an alert for every new order.
06
The review queue, orders, a printable delivery-slot manifest, the catalogue, discount codes, delivery fees and the homepage banners are all managed from one admin panel.

Request path
Letting the store adjust an order and refund the difference keeps the sale when one item can't be bought.
