Shopify Buy Button: Sell Shopify Products on Squarespace

The Shopify Buy Button lets you embed individual products or whole collections from a Shopify store directly into your Squarespace site, with Shopify handling the cart, checkout, and payments behind the scenes. It is the simplest way to keep a Squarespace site you love while using Shopify as the commerce engine. This page is a plain-English rundown of what it is, what it does, what it costs, and when it actually makes sense.

Best for: Squarespace owners who want their site’s design but need Shopify’s checkout, payment options, or inventory power behind it.

What it is

The Shopify Buy Button is a sales channel within Shopify that generates a small piece of embed code for a product or collection. You paste that code into a Squarespace Code Block, and it renders a product card with an Add to Cart button right on your page. When a visitor buys, the cart and checkout are handled entirely by Shopify (including payment processing, shipping, and tax), while your Squarespace site keeps doing what it does best: design, content, and branding. Product details, pricing, and stock stay in sync automatically from your Shopify admin, and all orders land in one place in Shopify.

The neat part for Squarespace owners is that this does not require a full Shopify store. Shopify’s entry-level Starter plan exists specifically for selling on external sites like Squarespace, so you get Shopify’s checkout without paying for a whole Shopify storefront.

What it does

The Buy Button bridges a Squarespace front end and a Shopify back end. Key points include:

• Embeds products or collections into any Squarespace page, blog post, or landing page via a Code Block.
• Shopify-powered checkout: cart, payments, shipping, and tax are all handled by Shopify, not Squarespace.
• Real-time sync: price, image, and stock changes in your Shopify admin update automatically wherever the button is embedded.
• Access to Shopify’s payment ecosystem, including Shop Pay and buy-now-pay-later options that Squarespace does not offer natively.
• Customisable look: adjust colours, button text, and layout, with a single-product or full-collection display.
• Unified order and inventory management in Shopify, even when products appear across several different sites.
• Works on Squarespace Business and Core plans and above, because it only needs a Code Block, not Squarespace Commerce.

Pricing

There are two pieces to budget for, since this approach uses both platforms. As a rough guide (check current pricing on each site):

• Shopify Starter: around $5 per month, the lowest-cost Shopify plan, built specifically for selling through Buy Buttons on external sites. It includes the Buy Button and Shopify checkout without a full storefront.
• Higher Shopify plans (Basic and up) also include the Buy Button, and make sense only if you also want a full Shopify store, lower transaction fees, or more advanced features.
• Squarespace: you need a Business or Core plan or above for Code Blocks, but notably not a Commerce plan, since Shopify handles the selling.
• Transaction fees: standard Shopify or payment-gateway fees apply on sales. Using Shopify Payments keeps these lowest.

The honest point: this is two subscriptions working together. It is genuinely cheap to start (around $5 a month on top of your existing Squarespace plan), but it only makes sense when Shopify gives you something Squarespace cannot.

Who it is for

This setup suits Squarespace owners who are committed to their Squarespace design but have hit a real limit in Squarespace’s native commerce, for example wanting Shop Pay or buy-now-pay-later options, needing Shopify’s stronger inventory and shipping tools, or selling the same products across several different websites and wanting one Shopify back end to manage them all. It is also handy for adding a quick Buy Button to a content-led site or blog without rebuilding it as a store. It is the wrong choice for most straightforward stores: if Squarespace’s built-in commerce already covers your needs, running two platforms just adds cost and complexity for no benefit. As one Squarespace commerce expert puts it, for most sellers the better move is to pick one platform and commit to it, not to bolt two together.

Our verdict

The Shopify Buy Button is the cleanest way to marry a Squarespace front end with a Shopify checkout, and at around $5 a month on the Starter plan it is an inexpensive way to access Shopify’s payment options and inventory tools without leaving the Squarespace site you have built. Setup is genuinely simple: create the button in Shopify, paste the code into a Code Block, done. The honest caveat is that this only earns its place when you need something specific that Squarespace Commerce cannot do, since otherwise you are paying for and maintaining two systems. If you have a clear reason (Shop Pay, multi-site selling, or Shopify’s commerce muscle) it is an excellent, low-cost bridge. If you do not, Squarespace’s native commerce is the simpler choice.

Frequently asked questions

Can I add a Shopify Buy Button to Squarespace?
Yes. You create the Buy Button in your Shopify admin, copy the embed code, and paste it into a Squarespace Code Block. The button shows your product and handles the cart and checkout through Shopify, while Squarespace handles your site’s design and content.

Do I need a Squarespace Commerce plan for this?
No. The Buy Button works through a Code Block, which is available on Squarespace Business and Core plans and above. You do not need a Commerce plan, because Shopify (not Squarespace) handles the checkout.

How much does it cost?
Shopify’s Starter plan is around $5 per month and includes the Buy Button, on top of your existing Squarespace plan. Standard Shopify or payment-gateway transaction fees apply on sales. Higher Shopify plans also include the Buy Button if you want a full store too.

Does my inventory stay in sync?
Yes. Product details, pricing, and stock are pulled in real time from your Shopify admin, so any change there updates automatically wherever the Buy Button is embedded, and all orders are managed in one place in Shopify.

Should I use the Shopify Buy Button or just Squarespace Commerce?
Use Squarespace Commerce if it already meets your needs, since one platform is simpler. Choose the Buy Button when you specifically need something Shopify offers that Squarespace does not, such as Shop Pay, buy-now-pay-later, stronger inventory tools, or selling across multiple sites from one back end.
