Shopify vs an AI-Built Online Store: The Real Costs
Shopify vs an AI-built online store: published plan prices, card fee maths at three sales levels, and the checkout jobs you take on if you build your own.
Shopify vs an AI-built online store comes down to what the platform fee actually buys you. The fee itself is easy to calculate. The harder part is the list of jobs a platform quietly does for you, which a store you build yourself will hand back to you one by one.
This post does the arithmetic first, then the job list, so you can see whether the saving is real.
Shopify vs an AI-built online store: what Shopify charges
The Shopify pricing page lists these plans in US dollars:
Plan | Per month, billed yearly | Per month, billed monthly | Online card rate | Fee on third-party payment gateways |
|---|---|---|---|---|
Basic | 29 | 39 | 2.9% + 30 cents | 2% |
Grow | 79 | 105 | 2.7% + 30 cents | 1% |
Advanced | 299 | 399 | 2.5% + 30 cents | 0.6% |
Plus | not listed | from 2,300 | 2.25% + 30 cents | 0.2% |
Check the page for the current figures before deciding, since plans and rates change.
The fees at three sales levels
Take a store whose average order is 50. Using the yearly prices and Shopify's own card rates, the monthly cost of each plan, subscription plus card fees, works out like this:
Monthly sales (orders) | Basic | Grow | Advanced |
|---|---|---|---|
2,000 (40 orders) | 99.00 | 145.00 | 361.00 |
10,000 (200 orders) | 379.00 | 409.00 | 609.00 |
50,000 (1,000 orders) | 1,779.00 | 1,729.00 | 1,849.00 |
Two things stand out. At low sales, the cheapest plan wins by a wide margin. And the upgrade logic is simple: moving from Basic to Grow costs 50 more per month and saves 0.2 percentage points on card fees, so it pays for itself only when monthly card sales pass 25,000. From Grow to Advanced the same calculation puts the crossover at 110,000 in monthly sales. Most small stores sit on the cheapest plan for a long time.
What the platform fee does not show
Your payment processor takes a cut whatever you build on. If you build your own store, you pay that processor's rate instead of Shopify's, so check their current price list, which I have not quoted here. What you stop paying is the subscription and, if you use an outside gateway on Shopify, that extra 0.6 to 2 percent.
At 10,000 a month, that third-party fee on Basic is 200. That is the case where building looks most attractive, a store that must use a specific payment provider.
The jobs you take on
A platform does these every day without being asked. A store you build must have each one, working:
Secure checkout. Card data handling, strong customer authentication where required, fraud checks. Use your processor's hosted payment page rather than building your own form, see adding payments to an AI-built app.
Tax. Rates by location, rounding, receipts. Rules differ by country and region, and the problem looks similar to sales tax on a subscription.
Failed payments and refunds. Retrying, notifying and reconciling, as in handling failed payments.
Money maths. Never store prices as floating point numbers. See handling money in an AI-built app.
Inventory. Stock counts that cannot go negative, with two buyers at once. Building an inventory app with AI covers the data model.
Shipping rates and labels, discount codes, abandoned cart emails, product feeds and an admin that staff can use at 6pm on a Friday.
Uptime and security updates. If your store goes down on a sales day, the person who fixes it is you.
A catalogue-size check
The size of your catalogue changes the job. With 15 products that rarely change, a hand-built page per product is manageable and an AI-built store is mostly a checkout flow. With 1,500 products and variants such as size and colour, you need bulk import, search, filters, image handling and a way to edit stock in volume, and each of those is a project of its own. If your catalogue is closer to the second, the platform fee is buying you a lot of finished work.
When building does make sense
An AI-built store is a reasonable choice when:
You sell something unusual: a configurator, subscriptions with strange rules, bookings mixed with products.
Your catalogue is tiny and stable, so you do not need the catalogue tools.
You already have a site and need a small order flow, not a whole platform.
You must use a payment provider that the platform charges extra for.
Stay on a platform when you sell standard physical goods, expect to grow, or have nobody to fix the store when it breaks. A middle path is to use the platform for checkout and inventory and build the unusual part, such as a custom product page, on top.
For the wider decision about running a small business on AI tools, see AI for small business.
Google's new shopping cart adds a wrinkle to this decision. Google Universal Cart checks out through the Universal Commerce Protocol, which Shopify co-developed, but Google's announcement does not say how stores on other platforms join.
Frequently asked questions
Is Shopify worth it for a small store?
For standard products and modest sales, usually yes. At 2,000 a month in sales the cheapest plan with card fees is around 99, which is a small cost for hosted checkout, tax tools and inventory.
Can I build my own online store with AI?
Yes, and it is realistic for a small catalogue. The risk sits in checkout, tax, refunds and inventory, which need careful testing, not in the product pages.
How much does Shopify charge in transaction fees?
On the pricing page, online card rates run from 2.9% + 30 cents on Basic down to 2.5% + 30 cents on Advanced, plus an extra fee if you use a third-party payment gateway.
When should I upgrade my Shopify plan?
When the card fee saving exceeds the extra subscription cost. Basic to Grow pays off at about 25,000 a month in card sales, using the published yearly prices and rates.
