Add Ecommerce Buying Feature

I’m ready to turn my existing site into a fully-functioning store for our physical products, and I need the checkout side set up from end to end. The core requirements are straightforward:

• Shoppers must be able to place physical-goods orders that ship to their home addresses.
• Credit and debit card processing is the only payment method we plan to offer at launch, so I’ll need a reliable, PCI-compliant gateway integrated (Stripe, Square, or another mainstream API—happy to follow your recommendation).
• After payment, the system should generate an order confirmation email, update stock levels automatically, and feed order details to our fulfillment workflow so we can print shipping labels and track delivery.

The site is already live; what’s missing is the cart, secure checkout, and order-management dashboard. Feel free to build on WooCommerce, Shopify custom app, or a clean Laravel/React stack—whichever gets us a stable, scalable solution fastest.

Deliverables
1. Responsive product pages with “Add to Cart” and quantity controls
2. Secure checkout flow with card payment, error handling, and success page
3. Admin view to see, filter, and update order status
4. Email templates for confirmation and shipping notices
5. Brief hand-off guide so my team can add products and adjust shipping fees

Once everything is tested and live, I’ll verify that a test purchase runs from cart all the way to a courier tracking number. If that passes, the job is complete.
