Digital Product Ecommerce Website Development

I’m ready to launch an online store dedicated exclusively to digital products and need a developer who can take the project from concept to a live, revenue-ready site. The core of the build is straightforward: customers must be able to purchase a file, download it instantly, or gain ongoing access through a membership area.

Key features I must see working flawlessly:
• Secure downloadable files – automatic delivery after successful payment, with expiring links to prevent sharing
• Tier-based membership access so repeat customers can log in and retrieve the content linked to their plan

On the checkout side, I want smooth, well-documented integrations for Credit/Debit Cards, PayPal, Razorpay, and direct Bank Transfer. Whichever platform or stack you recommend—whether WooCommerce, Shopify plus digital-delivery apps, or a lightweight custom build—performance and security are non-negotiable.

Deliverables I’ll sign off on:
1. Responsive storefront and product pages branded to my style guide
2. Configured download engine and membership area with role-based permissions
3. Integrated gateways (Card, PayPal, Razorpay, Bank Transfer) fully tested in sandbox and live modes
4. Admin dashboard walkthrough and a concise hand-off document so I can add products myself

Let me know which tech stack you propose, examples of similar digital-only stores you’ve launched, and a realistic turnaround time.
