How I Built a Digital Product Store with AI

I wanted to sell digital products — templates, guides, that kind of thing. The standard advice: use Gumroad or Shopify. Fine options, but they take a cut and limit customization.

So I built my own store. Here’s how that went.

The requirements

Simple e-commerce for digital products:

• Product pages with descriptions and screenshots
• Checkout that accepts credit cards
• Automatic delivery of files after purchase
• Basic sales analytics

Nothing fancy. Just the essentials to start selling.

Payment integration

This was the scariest part. Taking money online means dealing with payment processors, security, compliance. Lots of ways to mess up.

Used a merchant of record service. They handle payments, taxes, and compliance — I just embed their checkout. Worth the small fee to avoid the headaches.

The webhook integration took a few hours. When someone buys, the payment service notifies my server, and I trigger file delivery. Getting this reliable required understanding some infrastructure concepts.

Product pages

Built a template: hero image, product name and price, description, screenshot gallery, persistent buy button. Standard e-commerce layout.

Iterated on design details — making the gallery interactive, adding testimonials, improving the mobile layout. The foundation came together fast; the polish took longer.

Each product page follows the same template but pulls in different content. Adding a new product is just updating configuration.

The tricky parts

Email delivery was more complex than expected. After purchase, customers should get an email with download links. Setting up reliable email sending required understanding SMTP configuration and email deliverability.

Claude Code got me most of the way there, but I had to learn about SPF records and domain authentication. Not hard, just unfamiliar territory.

Analytics was another learning curve. I wanted to know what pages people visit, where they come from, what they buy. Ended up using a simple privacy-friendly analytics tool instead of building my own.

What I’d do differently

Start with fewer products. I launched with five products and the pages started feeling repetitive. Should have started with one great page, then expanded.

Use a simpler email solution. I overcomplicated the email system. Should have used a managed transactional email service from the start.

Don’t build what you can buy. For payments, using an established service was the right call. Fighting security and compliance is not where I wanted to spend time.

“Build the parts that differentiate you. Buy the parts that don’t.”

The outcome

Working digital store, fully under my control. No monthly fees (just transaction percentages). I can customize everything.

First sale came within a week of launching. Not life-changing revenue, but proof the system works. Real money from real customers, through something I built.

That feeling of seeing a purchase notification come through — hard to describe. Something you created, generating income while you sleep.

Is this for everyone?

If you’re selling a handful of digital products and want maximum control — this approach makes sense.

If you’re testing an idea or just starting out — use Gumroad. Seriously. Get sales first. Build custom later.

The best approach depends on your goals. AI makes building easier, but that doesn’t mean you should build everything.
