Course Overview
A store is not a website with a buy button. It is a set of promises: the price shown is the price charged, the stock count is true, the payment either completed or it did not, and the customer can find out which. Getting those right is what separates a shop that takes money from a shop that loses it.
This course builds a real store over fourteen chapters, in the order the decisions actually depend on each other: data first, then the pages, then the cart, then money, then the operations behind it. Every chapter names what you can do at the end of it.
You need to be able to build a database-driven website. If you cannot yet, the PHP and MySQL course or the MERN course comes first — both free.
What You’ll Learn
✅ The model: products, variants, prices, stock, and why each one is harder than it looks.
✅ The shop: catalogue, search and filters, a product page that answers the buying questions.
✅ Cart and checkout: a cart that survives a refresh, and a checkout that does not lose people.
✅ Payments: how a gateway actually works, what the callback means, and what never happens in the browser.
✅ Orders: confirmations, statuses, invoices, refunds and cancellations.
✅ Operations: stock, admin, shipping, tax and the reports that tell you whether it is working.
✅ Trust: security, speed, and the pages a customer needs before they will pay you.
The Chapters
1 — What a store must promise. The flow from landing to delivered, and every place it breaks. You can list the states an order can be in.
2 — Modelling products. Products, variants, SKUs, images, prices, stock. You can model a shirt in three sizes and two colours without duplicating a product.
3 — Catalogue and categories. Listing, sorting, filtering, pagination, search. A visitor can find a product three ways.
4 — The product page. Images, description, variant selection, stock state, price display. Your product page answers the questions that stop a purchase.
5 — The cart. Adding, updating, removing, persistence, price recalculation. A cart survives a refresh and cannot be edited into a discount by the customer.
6 — Accounts and guests. Registration, login, guest checkout, saved addresses. Someone can buy without an account, and someone with one buys faster.
7 — Checkout. Address, shipping choice, order summary, validation, and cutting the steps. You can walk a purchase from cart to "place order" with nothing unexplained.
8 — Payments, part one: how they work. Gateways, the redirect and callback dance, what the server confirms, and why the browser is never trusted. You can draw the payment flow and mark where the money is actually confirmed.
9 — Payments, part two: integrating one. Keys, test mode, a real gateway, webhooks, failed and duplicate payments. A test payment produces exactly one order, even if the customer double-clicks.
10 — Orders and after-sales. Statuses, confirmation emails, invoices, cancellation, refunds. A customer can tell what happened to their order without contacting you.
11 — Stock and admin. Inventory changes, overselling, an admin screen for products and orders. Someone who is not you can run the shop for a day.
12 — Shipping, tax and totals. Rates, zones, tax on a total, rounding, and getting the arithmetic exactly right. The total shown, the total charged and the invoice all agree, to the paisa.
13 — Trust, security and law. HTTPS, card data you must never store, passwords, rate limiting, and the policy pages a shop needs. You can say what customer data you hold and why.
14 — Launch and measure. Performance, a pre-launch checklist, analytics, and the funnel from view to purchase. Your store is live, and you know at which step people are leaving.
