How does Shopify work when there's nothing to ship? I run a marketplace with 5,000 products and no stock. Here's exactly how it's built.

What Can You Sell on Shopify?
The official answer is almost anything. The practical answer is that Shopify assumes you're selling a physical object — and if you're not, you have to tell it. Several times, on every product.
I run a training marketplace, and it's built entirely on Shopify: 5,000 courses from more than 170 providers, with no warehouse and nothing that's ever shipped. Shopify still thinks it's a shop. I've just switched off the parts that assume a box.
How Does Shopify Work for a Service Marketplace?
Here's the actual setup, piece by piece:
- A course is a product. Title, description, price, image — Shopify doesn't know the difference between a first aid course and a physical item, and that's exactly what makes this work.
- Dates are variants. Where a physical product might have size or colour options, a course has dates. Each date is a variant, shown as buttons on the page.
- Shipping is switched off. Every product is marked as not requiring shipping — miss this one tick box and the checkout tries to calculate postage on a training course.
- Inventory is untracked, with one exception. Course dates aren't stock. But category sponsorship — one advertiser per category — uses inventory tracking with a quantity of one, so Shopify's stock system enforces exclusivity without any custom code.
- The vendor field is the provider. Every provider gets their own collection page and product template automatically.
- Collections are rule-based. A course in Manchester lands on the Manchester page, the county page and the relevant subject page without anyone dragging it there.
The full cost breakdown of running a store like this — the bits that don't show up until the bill arrives — is covered in The Shopify Costs Nobody Warned Me About.
What Shopify Doesn't Do
This isn't a full multi-vendor marketplace. Providers don't log in or upload their own courses, and Shopify doesn't split payments automatically — the commission side is handled outside Shopify entirely. It's also never finished: dates expire constantly, so a catalogue this size is ongoing maintenance, not a project with an end date.
Is Shopify Worth It?
For this, yes. The checkout works, the hosting isn't my problem, and the structure underneath — products, variants, collections — bends a lot further than the marketing suggests. If you want to sell services, courses, bookings or anything else that doesn't come in a box, it'll do it. You just have to turn off the parts built for physical products.
How I Actually Manage a Catalogue This Size
None of this catalogue is run by hand. I connect Claude directly to the store using Shopify's connector, and manage products, collections and bulk updates entirely from a Chromebook — no terminal, no code. If you want the two-minute version of getting that set up, Getting Started with Connectors on Claude AI walks through it, and Claude AI for Beginners is the starting point if you're new to using Claude for work like this at all.
If you're earlier in the process — still deciding what to actually build your site or business on — What Should I Build It With? The Plain-English Stack Picker is the tool I built for exactly that decision, and how this channel found its focus covers why documenting tools like this became the format in the first place.
I also use Claude connected to Semrush to keep this catalogue's SEO in order — that process is covered in How to Use Claude for SEO Audits with Semrush.
This channel and website document the real transition from operator to creator — including the parts nobody talks about honestly.
