E-Commerce Coupon Website Development

I’m building a small e-commerce site devoted entirely to selling digital discount coupons and gift vouchers. The flow is simple: visitors browse the catalogue, add a voucher to cart, pay with either Credit/Debit Cards or a direct Bank Transfer, and immediately receive a unique coupon code in their inbox.

Besides the usual product pages and cart, I need a secure payment gateway integration for those two methods, an automated email system that pulls the purchased code from a database (or generates one on the fly) and sends it without manual intervention, and an admin panel where I can upload new codes, track sales, and see which codes have been redeemed. Responsive design is a must so shoppers on mobile can check out easily.

Deliverables:
• Fully functional website (frontend + backend) with product catalogue, cart, and checkout
• Payment gateway setup for Credit/Debit Cards and Bank Transfer
• Auto-dispatch email module that sends the correct coupon to the buyer instantly
• Admin panel for voucher management and sales reporting
• Basic instructions so I can add new codes and monitor orders on my own

Once the site passes testing—guest purchase, successful payment, instant email with a working code, and clean order logging—I’ll consider the project complete. If you’ve worked with WooCommerce, Shopify apps, or custom PHP/Laravel stores that handle digital products, your experience will be valuable, but I’m open to the stack you’re most efficient in as long as it’s reliable and secure.
