Verdict
A product catalog, Stripe-hosted checkout, and gated file delivery after payment is a real, working store — and it's realistically a one-sitting build, since Stripe Checkout does the hardest part (card handling, PCI compliance) for you. What's missing is everything BigCommerce operates behind the scenes: tax calculation and remittance across jurisdictions, marketplace channels, and fraud tooling tuned across millions of transactions.
Exhibit A — The prompt
Received on31.07.2026Build a personal storefront: a product catalog, Stripe-hosted Checkout, and gated delivery of digital files or lesson access after payment. Stack: Next.js, PostgreSQL, Stripe Checkout and webhooks, S3-compatible storage for files.
Core loop: the operator defines products with a name, price, and either an attached file or lesson content, plus optional coupon codes. A buyer clicks purchase, is sent to Stripe's hosted Checkout page (so card data never touches your server), and on a verified `checkout.session.completed` webhook — checked against Stripe's signature and an idempotency key so a retried webhook can't double-grant access — the buyer's email is added as a customer with a signed, time-limited download or lesson-access URL. A refund or chargeback webhook revokes access. Keep an append-only order log for support and dispute handling.
Requires a Stripe account (test mode is free to build against) and S3-compatible storage for files. Sales tax is explicitly the operator's own responsibility — Stripe Tax can be enabled for a per-transaction fee, or the operator handles it manually; this build does not calculate or remit tax itself.
Do not build: multi-channel marketplace listings, fraud scoring beyond what Stripe already provides, abandoned-cart email sequences, or course/community features like discussion forums and certificates — those are separate products, not this one's scope.Opening prefills the prompt — press enter to run it.
Exhibit B — What you lose
- B.1 automatic sales tax calculation and remittance across states and countries
- B.2 listing products on Amazon, eBay, and other marketplace channels from one dashboard
- B.3 fraud detection tuned across BigCommerce's full transaction volume
- B.4 built-in abandoned-cart recovery and marketing automation
- B.5 24/7 support when a payment or delivery issue needs a human
Prior art
Exhibit C — Why people still pay: payments, tax, distribution, and operations
People pay for BigCommerce because tax is the actual hard part of selling online — correctly calculating and remitting sales tax across every jurisdiction a buyer might be in is a compliance problem, not a coding problem, and getting it wrong has real legal consequences. The subscription buys that compliance layer plus fraud and marketplace tooling, not just a shopping cart.
Questions
Can I import my existing BigCommerce catalog?
BigCommerce exports products to CSV, and importing that into a matching schema is straightforward — the harder part is re-uploading digital files to your own storage, since BigCommerce doesn't hand those over in the export.
Will it work on my phone?
As a responsive storefront, yes — Stripe Checkout itself is mobile-optimized. Managing the product catalog and orders from a phone is workable but not built for it.
What does it cost to run?
Stripe takes its standard processing fee (around 2.9% + 30¢ per transaction) either way. Beyond that, hosting and storage run a few dollars a month — no separate platform fee like BigCommerce's monthly plan.
What's the one thing that doesn't survive the rebuild?
Tax compliance. BigCommerce calculates and can remit sales tax across jurisdictions automatically; here, that's either a paid Stripe Tax add-on or the operator's own legal responsibility to get right, and getting it wrong isn't a bug, it's a liability.
