How to Sell Digital Products with ChatGPT (Step by Step, 2026)

Sam Bakker · Founder, gocushy · July 16, 2026

ChatGPT can now operate real software on your behalf through connectors, which are built on MCP — the open Model Context Protocol. Stripe's own MCP will hand your agent a payment link, and that's genuinely useful. But a payment link is a cash register: it collects the payment, and that's the job — no bump, no upsell, no follow-up funnel. This guide shows you how to give ChatGPT the whole store — order bumps, one-click upsells, real tax, compliant invoices — while the money lands directly in your own Stripe account. If you want the background first, read what an MCP checkout actually is. This is the practical version: numbered steps, the exact prompts to type, and the kind of responses you'll see back.

What you'll need

• A gocushy account — create one at gocushy.com/signup
• A Stripe account (or ten minutes to create one)
• A ChatGPT plan that supports custom connectors — as of this writing that means a paid plan, and availability varies by region, so check OpenAI's current docs
• Something to sell: a course, ebook, template pack, coaching offer — any digital product

Step 1 — Create your gocushy account

Sign up at gocushy.com/signup. Once you're in, grab your API key from the dashboard — it starts with gc_. This key is what lets ChatGPT act on your account, so treat it exactly like a password. That's the whole step; everything your account needs beyond this can be set up by the agent later.

Step 2 — Connect Stripe (the one human step)

From your gocushy dashboard, click Connect Stripe. You'll go through Stripe's onboarding — identity verification, business details, bank account. This is KYC ("know your customer"), and it's the one part of the whole process a human legally has to do. No agent can, or should, verify your identity for you.

It's worth pausing on why this matters: gocushy connects to your Stripe account via Stripe Connect. We never hold your funds. When someone buys, the charge happens on your Stripe, and payouts follow your normal Stripe schedule. You're not handing your revenue to a middleman — you're giving your AI a set of controls that operate your own accounts.

Step 3 — Add the connector in ChatGPT

In ChatGPT, open Settings → Connectors and add a new connector with this URL, substituting your real API key:

https://gocushy-mcp.fly.dev/mcp/YOUR_API_KEY

That's it. ChatGPT now has access to gocushy's 22 agent tools — creating products and offers, customizing checkouts, wiring email follow-up, reading sales, issuing refunds, managing affiliates. The full tool list is in the developer docs. (Using Claude, Claude Code, or Cursor instead? Run npx -y @gocushy/mcp with your key — same tools, same prompts.)

Step 4 — Import your products

If you already sell through Stripe, your catalog comes over in one prompt:

Starting from zero? Just describe the product instead — "Create a $149 product called Launch Course, delivered at courses.example.com/launch" — and the agent creates it, including the access URL buyers get after purchase.

The transcripts in this guide are illustrative examples — your agent's wording, your products, and your numbers will differ.

Step 5 — Build the offer: bump and upsell included

This is where a checkout stops being a payment link. Order bumps (a checkbox add-on at checkout) typically add 20–40% to average order value, and one-click post-purchase upsells charge the buyer's saved card without re-entering payment details. Both are built into every gocushy one-time offer — the deeper mechanics are in our guide to order bumps and one-click upsells on Stripe.

Step 6 — Customize the checkout (honestly)

gocushy checkouts are "described, not designed." You tell the agent what the page should say — headline, up to six benefit bullets, up to three testimonials, a guarantee badge, a hero image, your brand accent color — and it slots into a layout that's structurally unbreakable. An agent literally cannot ship you a broken page.

That last part isn't a limitation, it's a feature. Fake evergreen countdowns are the fastest way to torch trust with an audience. On gocushy, they're impossible.

Step 7 — Get the link and put it anywhere

Drop the hosted link in emails and bios, or ask for the embed code and paste it into whatever page your AI built this morning. Details for both are in the docs.

Step 8 — Check sales without opening a dashboard

This is the part traditional checkout tools weren't built for: your agent doesn't just build the funnel, it reads the results and iterates. There's a full dashboard and accounting-grade CSV export too — but you may find you rarely open them.

Step 9 — Issue a refund

What ChatGPT cannot do here (on purpose)

Handing an agent your sales machinery only works if the machinery has guardrails the agent can't talk its way around. These live on the server, not in the prompt:

• It can't move your money out. There are no transfer or payout tools. Buyers pay on Stripe's rails straight into your Stripe account, and gocushy never holds funds — the only money-touching action an agent has is refunding a buyer's own order back to their card.
• It can't break prices. Pricing is enforced server-side. A confused (or manipulated) agent cannot ship a mispriced or broken checkout.
• It can't fake scarcity. Countdowns hide at zero and can never reset. Honest deadlines are the only kind the system can produce.
• It can't skip KYC. Stripe identity verification is yours alone — the law requires a human, and that's the single human touchpoint in this whole setup.

What about tax, receipts, and invoices?

Handled, and on your registrations rather than a middleman's. Checkouts run Stripe Tax against the merchant's own tax registrations, collect a business tax ID from buyers, apply EU B2B reverse charge with VIES validation, and handle NZ/AU GST — including tax on upsells. Every order generates a sequential, compliant invoice (labelled "Tax Invoice" for NZ/AU buyers) linked from the receipt. If you run Xero, paid orders auto-file as authorised invoices. For the full picture, see VAT and GST for digital products on your own Stripe.

None of this is tax or legal advice — tax obligations depend on your registrations and where your buyers are, so talk to your accountant about what applies to you.

When you don't need any of this

Honest moment: if you're collecting a one-off payment — a deposit, a single invoice, a low-volume product with no follow-up — a bare Stripe payment link is the better choice. It's included with Stripe, costs nothing beyond processing fees as of this writing, and takes a minute to make. ChatGPT can already generate one via Stripe's own MCP. gocushy earns its keep when the sale has more than one moving part:

Comparison reflects Stripe payment links as of this writing — Stripe's features evolve, so check their current docs.

The same logic applies to the deeper platform question — whether to sell on your own Stripe at all or use a merchant of record. We've written up that trade-off separately in merchant of record vs your own Stripe.
