E-commerce guide
Build an e-commerce store with AI
Product catalog, cart, Stripe checkout, order tracking, customer accounts. The Shopify shape, owned by you, on your own domain — no $39/month plan and no per-transaction fees on top of Stripe.
01 / What you can build
Real projects, not toy examples.
People are shipping these e-commerce stores on Webtwizz this quarter. Each one is a complete app: real auth, real data, real money flowing through Stripe.
Single-product store
You sell one thing. A landing page + Stripe checkout + thank-you flow + email receipts.
Niche multi-product store
20–500 products with variants (size, color), cart, shipping rates by zone, customer accounts.
Digital goods store
Templates, courses, ebooks, software licenses. Auto-deliver via email after purchase.
Subscription box / monthly product
Recurring billing via Stripe Subscriptions, fulfillment scheduled monthly.
02 / The build
From a sentence to a deployed app.
5 ordered steps. No config files, no devops, no SQL migrations to write by hand.
- 01
Describe your store
Prompt Webtwizz: "An e-commerce store for my hot-sauce brand. 12 products, 3 variants each (mild/medium/hot), $8–18 prices, US-only shipping, customer accounts." Webtwizz scaffolds catalog + cart + checkout.
- 02
Connect Supabase for products + orders
Webtwizz creates tables for products, variants, inventory, customers, orders, and order items. Edit product details inline or via the admin page Webtwizz scaffolds.
- 03
Connect Stripe for checkout
One-click Stripe connection. Webtwizz uses Stripe Checkout (hosted) for the payment step — PCI-compliant, Apple Pay, Google Pay all work. Webhooks fire on `checkout.session.completed` to mark the order paid.
- 04
Connect Resend for receipts + shipping notifications
Order confirmation, payment receipt, "your order has shipped" emails. Templates editable visually. Customer account page shows order history.
- 05
Customize the storefront and ship
Product cards, hero, cart drawer, checkout copy — all editable visually. Add your domain, hit publish. shop.yourdomain.com is live with SSL.
03 / Why it works
The parts other AI builders skip.
Anyone can scaffold a CRUD app. The reason these projects ship is the integration plumbing other builders leave for you.
Real cart with inventory holds
Inventory deducts atomically at checkout. Two customers can’t buy the last unit at the same time.
Stripe Checkout, not a janky form
Webtwizz uses Stripe’s hosted checkout — PCI-compliant, Apple Pay, Google Pay, BNPL options work out of the box.
Customer accounts (optional)
Order history, saved addresses, re-order in one click. Or guest checkout if you’d rather not.
No platform fees on top of Stripe
Pay Stripe’s 2.9% + 30¢, that’s it. No "Shopify Basic $39/month + 2% transaction fee."
04 / The stack
Wired up. One click each.
Supabase, Stripe, the email layer, the analytics layer. OAuth, env vars, webhooks, scaffolded routes, all generated correctly the first time.
Supabase
Products, variants, inventory, orders, customers.
Stripe
Checkout, payment confirmation webhooks, refunds.
Resend
Order receipts, shipping notifications, abandoned-cart emails.
05 / Questions
The honest answers.
The questions founders actually ask before they commit to a stack.
How is this different from Shopify?
Shopify is the right answer if you want plug-and-play and don’t mind $39+/month + 2% transaction fees + per-app fees stacking up. Webtwizz is the right answer if you want to own the storefront, customize freely, and pay only Stripe fees + hosting.
What about shipping rates?
Webtwizz scaffolds basic shipping zones (flat rate by country/state). For real-time carrier rates (USPS, UPS, FedEx), connect Shippo or EasyPost — the AI route is a fetch call you can wire to any shipping API.
Can I sell internationally?
Yes. Stripe accepts cards from 195+ countries. Add VAT/tax handling via Stripe Tax (one-click) and customs tax via your shipping API. Webtwizz can also scaffold multi-currency display.
What about inventory across multiple sales channels?
If you’re selling on Etsy/Amazon/Instagram too, you’ll want a central inventory source. Either keep Webtwizz as the source of truth and sync out via webhooks, or use a tool like Linnworks and sync in. Both are doable as Next.js cron jobs.
Will it scale to thousands of orders a day?
Yes. Each Webtwizz project runs on its own machine with auto-scaling. The bottleneck for most stores isn’t the storefront — it’s fulfillment and support. Stripe + Supabase comfortably handle thousands of orders/day.
