Shopify vs Squarespace for Your Online Store

By Milan Dhameliya · · 8 min read

Compare Shopify and Squarespace by inventory, POS stock updates, local-currency checkout, and shipping eligibility. Decide when staying makes more sense than migrating.

Choose Shopify for an online store when location-level inventory, fulfillment integrations, or market-specific selling are central to how you operate; choose Squarespace when its supported selling workflows already meet your needs and your team prefers managing the site there. The decision should turn on a demonstrated operational requirement, not a product-count rule or the assumption that Squarespace cannot accept international or in-person payments.

For an existing store, I would require a specific reason to migrate: a recurring manual task, an unsupported delivery promise, or a customer experience you cannot implement reliably. For a new store, I would demonstrate those same requirements before approving the design. This comparison explains what to verify and what evidence would make me choose either platform.

Stay with Squarespace when the store already does the job

I would keep Squarespace on the shortlist when your team can publish the pages it needs, sell the required product types, and handle orders without recurring reconciliation work. A platform move is not a useful growth project by itself. Write down what the move would let your staff or customers do differently.

Do not use “more than 50 products” as an automatic migration trigger. Squarespace's product documentation lists up to 10,000 products per store page in version 7.1, versus 200 in version 7.0, and up to 250 variants per product. Those are documented limits, not a recommendation to fill every available slot.

Catalog complexity deserves a separate conversation. Ask your merchandiser to build your most awkward product, including its actual sizes, colors, images, and stock records. Then have another team member change it. A catalog that fits numerically can still be inconvenient to maintain; conversely, a larger catalog with straightforward products may not justify a rebuild.

For a site where editorial pages and brand presentation dominate the weekly workload, include the content editor in the decision. Ask them to publish a product story, link it to the correct items, and revise it for mobile. Judge the workflow your team can repeat, rather than a demo prepared by someone who knows the platform exceptionally well.

Choose Shopify when inventory locations need to govern fulfillment

Shopify's locations system supports separate inventory at physical locations, fulfillment assignment, and order routing. Locations can include warehouses, retail stores, pop-ups, and certain fulfillment apps. Location allowances depend on the plan.

That makes Shopify a strong candidate when the question is more precise than “is this item in stock?” You may need to know whether it is available at the pickup location, which warehouse should ship it, or which fulfillment partner owns it. My preference for Shopify in that situation rests on its documented operating model, not a promise that every integration works automatically.

Use a deliberately awkward sample: one variant stocked in the shop, another only at the warehouse, and a cart containing both. Ask whoever proposes the implementation to show the stock records, the fulfillment assignment, and the customer-facing delivery choices. Record any app that changes those decisions.

Squarespace also has an extensions directory covering inventory, shipping, and finance. Check the exact connector rather than assuming there are none. Require the provider to demonstrate your stock updates and refunds, including how the team sees a failed sync. If an existing integration meets the requirement cleanly, that is evidence for staying.

“Supports POS” does not answer what happens to stock

Squarespace's current in-person selling guide covers the US and UK, with payment methods varying by region. It documents automatic inventory updates for supported Tap to Pay sales, but manual stock updates for physical products sold through Pay Links. The Square Reader integration is US-only.

A payment taken successfully at a pop-up is not proof that the online store's last unit was removed from sale. This is the distinction I would make the team demonstrate before selecting a platform for retail and ecommerce together.

For an illustrative acceptance test, create a test SKU with one unit available. Follow the actual in-person method your staff intend to use, then inspect its online availability. Repeat the stock check after a return. Use the provider's supported testing process and agree who handles any necessary live transaction; do not infer inventory behavior from a generic payment demo.

For a UK merchant, a Squarespace demonstration using a US-only reader is not relevant evidence. For a merchant in Australia, Canada, New Zealand, or Ireland, the US and UK availability described above should not be treated as local availability. Check your own payment method, device, and country with either platform before buying hardware or committing to a retail rollout.

International checkout needs a processor-specific comparison

It would be wrong to dismiss Squarespace with a blanket claim that shoppers can only pay in the store's primary currency. Its currency guide documents multi-currency checkout with Squarespace Payments or Stripe, enabled by default, while payouts remain in the primary currency. PayPal alone does not qualify. The documented scope includes one-time store purchases, invoices, pay links, and donations.

Shopify also has conditions. Its market currency documentation requires Shopify Payments or Adyen for multi-currency processing. Other providers process orders in the store's default currency. In Shopify, review Markets > the relevant market > Currency; in Squarespace, review Payment Settings > Currency > Multi-currency.

For either platform, put the intended processor and payment method beside each target country in your requirements. Confirm that your business is eligible to activate that processor before counting its capabilities. Then establish what the shopper sees on the product page, what currency is charged, and what the team receives in its payout records. If subscriptions matter, investigate that recurring-payment workflow separately instead of extending a one-time-purchase claim to it.

I would favor Shopify when the project requires a broader market-specific operating setup that the team can demonstrate there. I would not migrate a working Squarespace store solely to obtain a local-currency checkout that its current processor already supports. Capabilities in this comparison were checked on October 10, 2026; that is a verification date, not a claimed launch date.

Price the shipping requirement before selecting the plan

Separate three questions: can you display a default carrier rate, can you connect your own negotiated account, and can you serve the required origin-to-destination route? “Real-time shipping” is too broad a requirement to price accurately.

Squarespace's carrier-calculated shipping documentation distinguishes default carrier options from connecting your own account. It lists Core, Plus, and Advanced for supported default options, with country restrictions; an own-account connection requires Advanced or Commerce Advanced. The documented feature covers domestic shipments, not cross-border shipping. Its country table lists Advanced for Ireland, versus Core, Plus, and Advanced for the US, UK, Australia, Canada, and New Zealand.

Shopify's UPS setup guide distinguishes Shopify-provided rates from connecting your own carrier account. Third-party carrier-calculated shipping is included on Advanced and Plus; Grow can add it through annual billing or an additional monthly fee. It is unavailable on Basic and Starter. This restriction does not mean every Shopify-provided carrier rate requires an upgraded plan.

For Shopify's own-account UPS setup, the documented path is Settings > Shipping and delivery > Carrier accounts > Connect account > UPS. For Squarespace, start with Shipping > Add shipping option > Carrier-calculated. Available choices still depend on the account and location.

Ask for a quote using a real packed order and your actual shipping route. Include a mixed cart and an address you regularly serve. Compare the checkout offer with the service you intend to buy. If a platform needs an extension or different plan for that route, include it in the comparison before approving the build.

Compare the proposed setups, not two entry-level prices

I would request two written scopes using the same requirements. Each should identify the platform plan, processor, shipping setup, essential integrations, staff responsibilities, and ongoing maintenance. Require published vendor pricing or a written project quote for each paid item; do not fill gaps with a generic “apps budget.”

Keep these three groups separate:

Record manual work separately in staff time. A weekly stock correction is neither a subscription fee nor free. Let the person who performs it estimate the effort from actual records. That creates a decision your team can defend without inventing a universal revenue threshold for moving to Shopify.

A migration is justified when the improvement survives the move

Before signing a Shopify rebuild, take a representative export from Squarespace. Shopify's Squarespace migration guide requires product CSV remapping; multi-location quantities need an inventory CSV rather than the product file's single-location quantity column. It also treats customer records, reviews, and historical orders as separate migration tasks.

That matters when the proposed benefit is better inventory control: demonstrate the stock mapping before celebrating a successful product import. Use our Shopify migration tool comparison to choose a transfer method, and our agency-versus-DIY migration guide to decide who should own the work.

My final decision record would contain four items: the requirement that currently fails, the demonstrated replacement behavior, the complete operating cost, and the person responsible after launch. If neither platform passes a critical requirement, keep evaluating the implementation rather than awarding a winner for its homepage design.

Choose Squarespace when the required workflows pass and the team benefits from staying. Choose Shopify when its demonstrated operating model removes a meaningful limitation and the migration scope preserves the records your business depends on. If you need help establishing that scope, Code Kaarigari's Shopify services can turn your actual catalog and order workflows into a reviewable implementation plan.
