Squarespace vs Wix for E-commerce: Checkout and Payment Compared

Setting the Stage: Why the Checkout Experience Defines E-Commerce Success

Squarespace and Wix both market themselves as all-in-one website platforms, but when it comes to e-commerce, they are fundamentally different products built on different architectural philosophies. Squarespace evolved from a design-forward portfolio platform and later bolted on commerce functionality, while Wix rebuilt its e-commerce engine around native business tools from the ground up. The checkout and payment experience—the final, revenue-critical moments of every customer journey—reveals these architectural differences more starkly than any marketing comparison page ever could.

According to the Baymard Institute, the average documented online shopping cart abandonment rate sits at approximately 70%, with 17% of abandonments specifically attributed to a checkout process that was too long or complicated. When you multiply even a 5% improvement in checkout conversion by a full year's revenue, the platform you choose is not a design preference—it is a direct revenue lever. This head-to-head analysis from Hosting Captain isolates the checkout and payment experience on both platforms, with specific attention to the features that affect your bottom line: payment gateway availability, transaction fee structures, shipping calculation flexibility, tax handling accuracy, and inventory management integration.

We tested both platforms in mid-2026 using their current e-commerce plans. Our test store sold a mix of physical goods (with weight-based shipping), digital downloads, and subscription products to stress-test the full range of commerce features. Every observation in this article is based on that hands-on testing, not on vendor marketing materials.

Checkout Flow Design and Customization

The checkout experience begins the moment a customer clicks "Add to Cart" or "Buy Now." Both Squarespace and Wix offer express checkout options—Squarespace through its native checkout overlay and Wix through its customizable cart and checkout pages—but the depth of control available differs considerably.

Squarespace Checkout: Squarespace uses a unified, platform-controlled checkout overlay that appears as a modal window on top of the product page or a dedicated checkout page at the /checkout path. The layout is clean, minimalist, and visually consistent with the rest of the site's design. However, customization options are limited. You can adjust the checkout page's header and footer branding, add a custom checkout note or delivery instructions field, and choose whether to display a coupon code field. You cannot rearrange the field order, add custom fields beyond the available toggles (company name, phone number, address line 2), or inject custom JavaScript into the checkout flow.

The constraint that frustrates many store owners is the inability to modify the checkout button text, color, or placement beyond Squarespace's global style settings. If your site uses a custom call-to-action strategy—"Complete My Order" versus the default "Place Order"—you cannot implement it. Squarespace's checkout also forces account creation for customers, which reduces friction for return buyers but creates a barrier for one-time purchasers who prefer guest checkout. As of 2026, guest checkout is available on Squarespace but requires the customer to manually deselect the account creation option, which is enabled by default.

Wix Checkout: Wix provides a fully customizable checkout page built with its standard page editor. You can drag and drop elements, reorder form fields, add custom sections above or below the checkout form, and inject trust badges, testimonials, or guarantee seals exactly where you want them. The checkout page supports Wix's native design features—animations, video backgrounds, custom fonts—which means the checkout can feel like a seamless continuation of your store's branded experience rather than a detour into a generic payment portal.

Wix also offers a one-page checkout option (versus a multi-step flow), which the platform's own conversion data suggests can increase completion rates by 5–10% for simple product catalogs. Custom checkout fields are supported via Wix's form builder, and you can add conditional logic that shows or hides fields based on cart contents or customer selections—for example, revealing a "gift message" field only when a customer selects the gift-wrapping option. This level of checkout customization is not available on Squarespace without third-party code injection, and even then, the options are limited.

Bottom Line on Checkout: Wix wins on checkout flexibility by a significant margin. Squarespace's checkout is visually elegant but functionally inflexible. If your conversion optimization strategy involves A/B testing checkout layouts, custom fields, or post-purchase upsell flows, Wix provides the infrastructure to execute that strategy; Squarespace does not.

Payment Gateways and Processor Options

Payment gateway choice determines which credit cards, digital wallets, and local payment methods your customers can use—and how much of each transaction you keep after processing fees. This section maps the gateway landscape on both platforms.

Squarespace Payment Gateways: Squarespace connects to Stripe, PayPal (including PayPal Checkout, Venmo, and Pay Later options), Afterpay (via Stripe integration), and Clearpay. Squarespace Commerce plans also support Square for in-person payments, making it one of the few platforms that bridges online and point-of-sale transactions natively. Notably, Squarespace does not support Authorize.net, Braintree, or any direct merchant account integrations—if you process payments through a bank-provided merchant account rather than an aggregator like Stripe, Squarespace is not your platform.

Digital wallet support on Squarespace is excellent: Apple Pay and Google Pay are supported via Stripe's payment request button, which appears automatically on compatible devices. However, this support requires that Stripe is connected as your primary payment processor—if you only use PayPal, Apple Pay is not available.

Wix Payment Gateways: Wix supports a broader range of payment gateways. Beyond Stripe, PayPal, and Square, Wix integrates with Authorize.net, Braintree, 2Checkout (now Verifone), PayU, PagSeguro, Mercado Pago, iDEAL, Sofort, Giropay, Bancontact, and more than 50 regional payment methods through its global payments network. This breadth makes Wix significantly more viable for stores selling internationally, where local payment preferences—iDEAL in the Netherlands, Bancontact in Belgium, Mercado Pago in Latin America—can account for 40–60% of transactions.

Manual payment methods (bank transfer, cash on delivery, purchase order) are supported on both platforms, but Wix offers more granular control over when these methods appear—for example, limiting cash on delivery to specific postal codes.

Bottom Line on Gateways: Wix provides meaningfully more payment gateway options, particularly for international and regional payment methods. Squarespace's Stripe-plus-PayPal combination covers the vast majority of North American and Western European customers, but stores with international customer bases or those requiring specific merchant account integrations will find Wix substantially more accommodating.

Transaction Fees: The Hidden Revenue Leak

Both platforms charge transaction fees on top of the payment processor's standard rates—and the differences compound quickly at scale.

Squarespace Transaction Fees: Squarespace charges a platform transaction fee on the Business plan (the entry-level commerce tier): 3% per transaction. On the Basic Commerce and Advanced Commerce plans, Squarespace charges 0% platform transaction fees—you pay only the Stripe or PayPal processing fee (typically 2.9% + US$0.30 for domestic US cards on Stripe). The Advanced Commerce plan (US$49/month) removes transaction fees entirely and adds abandoned cart recovery and subscription selling.

The 3% fee on the Business plan is aggressive. If you sell US$10,000/month on the Business plan (US$23/month), you pay US$300 in transaction fees versus US$0 on the Basic Commerce plan (US$27/month). The US$4/month price difference between the Business and Basic Commerce plans pays for itself at approximately US$133 in monthly sales. Anyone selling more than a few hundred dollars per month should skip the Business plan for e-commerce purposes.

Wix Transaction Fees: Wix does not charge platform transaction fees on any of its Business & eCommerce plans—the processing fee you see is the payment gateway's standard rate (typically 2.9% + US$0.30 for US Stripe transactions, or Wix Payments at a comparable rate). Wix Payments, the platform's native payment processor, offers rates that vary by region but are generally competitive with Stripe. The absence of a second-layer transaction fee means that even Wix's Core plan (US$27/month) matches Squarespace's Commerce Basic plan on fee structure.

This fee difference is one of the most consequential economic factors in the platform comparison. A store processing US$50,000/month pays US$0 in platform fees on Wix and US$0 on Squarespace's Advanced Commerce plan—but on Squarespace's lower-tier plans, that same store would pay US$1,500/month in platform transaction fees. The message is clear: if you choose Squarespace for e-commerce, you must be on at minimum the Basic Commerce plan, which effectively raises the true cost of Squarespace e-commerce to US$27/month.

Bottom Line on Fees: Wix edges ahead because it charges zero platform transaction fees at every plan tier. Squarespace's 3% fee on the Business plan is prohibitive for any store with meaningful sales volume, though the Advanced Commerce plan eliminates this gap at US$49/month.

Shipping Rate Calculation and Carrier Integration

Accurate, flexible shipping is a conversion driver and a margin protector. Both platforms offer real-time carrier-calculated shipping, but the implementation details matter.

Squarespace Shipping: Squarespace provides real-time shipping rates from USPS, FedEx, UPS, and DHL Express on the Advanced Commerce plan only. The Basic Commerce plan is limited to flat-rate shipping, weight-based tiers, and free shipping rules. Real-time carrier rates are not available on the Business plan. This tier gating is a significant limitation—if you ship physical products and want to charge customers accurate, real-time rates rather than estimated flat rates, you must be on the most expensive plan.

Squarespace's shipping zone setup is straightforward: define regions (countries, states, postal codes) and configure which rates are available within each zone. You can offer a mix of flat-rate and carrier-calculated options within a single zone, and you can create product-specific shipping rules that override zone defaults for oversized or fragile items. However, Squarespace does not support dimensional weight ("DIM weight") calculations natively—if you sell large, lightweight items where carriers charge based on package volume rather than actual weight, you must manually inflate your product weights to approximate DIM pricing.

Wix Shipping: Wix supports real-time carrier rates from USPS, FedEx, UPS, Canada Post, and Sendcloud (for European carriers) across all Business & eCommerce plans—there is no plan-level gate. You can also configure Wix Shipping, the platform's own label printing and rate discount service, which provides discounted USPS rates comparable to third-party shipping platforms like ShipStation or Pirate Ship.

Wix's shipping rules engine is more granular than Squarespace's. You can create shipping rules based on weight, price, product category, and destination region simultaneously—for example, "free shipping on orders over US$75 containing products from the 'Apparel' category and shipping to the continental US." Wix also supports dimensional weight calculations, which is critical for stores selling furniture, lighting, sports equipment, or any product where package size drives shipping cost more than actual weight.

Bottom Line on Shipping: Wix's real-time carrier rates are available on all e-commerce plans, while Squarespace gates them behind the most expensive Advanced Commerce plan (US$49/month). Wix's shipping rules engine is also more flexible, with dimensional weight support that Squarespace lacks. Wix is the stronger choice for physical-product stores with complex shipping requirements.

Tax Handling and Compliance

Sales tax compliance is one of the most administratively painful aspects of running an online store, and your platform's tax engine determines whether you spend minutes or hours per month keeping the tax authorities satisfied.

Squarespace Tax Handling: Squarespace supports automatic tax calculation for US sales tax, Canadian GST/HST/PST, EU VAT, UK VAT, Australian GST, and New Zealand GST. The platform uses a built-in tax engine (not TaxJar or Avalara) that pulls tax rates from a maintained database. Squarespace automatically determines taxability based on the customer's shipping address and applies the appropriate rate at checkout.

For US merchants, Squarespace's tax engine handles economic nexus thresholds—you configure the states where you have a tax obligation, and the platform applies the correct state, county, city, and special district tax rates for those states. Product-level tax overrides are available, which is essential if you sell a mix of taxable and tax-exempt products (clothing in certain states, groceries, prescription items). Squarespace also generates tax reports that list taxable sales by jurisdiction, which you can export for filing—but these reports are summary-level, not form-ready. You will still need to manually file returns or use a tax filing service.

Wix Tax Handling: Wix uses Avalara, a leading third-party tax compliance engine, for automatic tax calculation on the Business Elite plan (US$159/month). On lower-tier Business & eCommerce plans, Wix provides a manual tax configuration system where you set rates per region, or you can integrate TaxJar or Avalara as a third-party add-on via the Wix App Market.

The Avalara integration on the Elite plan is a significant differentiator: Avalara provides automated tax calculation for over 14,000 US tax jurisdictions, real-time rate updates when jurisdictions change their rates, automated tax return filing (as an add-on service), and exemption certificate management for B2B sales. If your store processes more than US$100,000/year in taxable sales across multiple US states, the hours saved by Avalara automation—and the audit protection it provides—can justify the Elite plan's cost on its own.

For EU merchants, Wix's tax handling includes automatic VAT rate application and validation of EU VAT IDs at checkout (for B2B transactions where VAT is reverse-charged). Squarespace also validates EU VAT IDs but requires a Commerce Advanced plan for this feature.

Bottom Line on Tax: For stores with simple tax requirements (one or two states, a handful of tax-exempt products), both platforms are adequate. For stores with multi-state nexus, complex product taxability rules, or B2B sales requiring exemption certificates, Wix's Avalara integration (via the Elite plan) provides enterprise-grade tax compliance that Squarespace's built-in engine cannot match.

Inventory Management and Multi-Channel Selling

Inventory management is the operational backbone of e-commerce. Over-selling a product damages customer trust, while under-stocking due to poor demand forecasting leaves revenue on the table.

Squarespace Inventory Management: Squarespace provides a capable, if somewhat streamlined, inventory system. You can track inventory at the SKU level, set low-stock alerts, and configure whether out-of-stock products display to customers or are hidden automatically. Product variants—size, color, material—each have their own SKU and inventory count. Squarespace supports unlimited products and variants on all commerce plans, which is generous compared to platforms that cap SKU counts on lower tiers.

Squarespace's physical retail integration via Square is a differentiator: if you also sell in person at markets, pop-ups, or a retail store, inventory syncs between your online Squarespace store and your Square point-of-sale system in near real-time. This omnichannel capability is rare at this price point and makes Squarespace uniquely appealing for businesses that split sales between online and physical channels.

However, Squarespace's inventory reporting is basic. You can export a CSV of current inventory levels, but the platform does not provide demand forecasting, reorder point recommendations, or profit margin analysis by product. For multi-channel selling beyond Square POS—Amazon, eBay, Etsy, social commerce—Squarespace requires third-party integrations through services like Trunk or Syncio, which add monthly costs.

Wix Inventory Management: Wix's inventory system is deeper and better suited to multi-channel operations. In addition to standard variant-level tracking and low-stock alerts, Wix provides demand forecasting, supplier management (tracking multiple suppliers per product), purchase order generation, and cost-of-goods-sold (COGS) tracking that feeds into profit reporting. The inventory dashboard surfaces your best-selling products, slow movers, and products approaching stockout thresholds in a single view.

Wix's multi-channel selling is native: you can connect your Wix store to Amazon, eBay, Facebook, Instagram, and Google Shopping through the platform's sales channel integrations without third-party middleware. Inventory syncs across all connected channels automatically, and orders from all channels appear in a unified order management dashboard. Wix also supports dropshipping integrations (Modalyst, Spocket, Printful) that synchronize supplier inventory into your Wix store and automate order routing to the dropshipping supplier.

Bottom Line on Inventory: Wix provides a substantially more sophisticated inventory management system with native multi-channel selling, demand forecasting, and dropshipping support. Squarespace's inventory system is adequate for single-channel, direct-to-consumer stores—particularly those with Square POS integration—but lacks the operational depth required for multi-channel retail.

Abandoned Cart Recovery and Post-Purchase Features

Recovering abandoned carts is one of the highest-ROI activities in e-commerce. Both platforms offer abandoned cart recovery, but the feature set and plan availability differ considerably.

Squarespace Abandoned Cart Recovery: Abandoned cart recovery is available only on the Advanced Commerce plan (US$49/month). When enabled, Squarespace automatically sends a single email to customers who began checkout but did not complete their purchase, typically 24 hours after abandonment. The email template is customizable—you can adjust the subject line, body text, and button label—but you cannot create multi-step recovery sequences, segment abandoned carts by value, or offer dynamic discount codes in recovery emails.

Wix Abandoned Cart Recovery: Wix offers abandoned cart recovery on all Business & eCommerce plans. The recovery system supports automated email sequences—a first reminder at 1 hour, a second at 24 hours, and an optional third with a discount incentive—rather than a single email. You can create multiple recovery workflows triggered by cart value, product category, or customer type (new versus returning). Wix's automation builder also supports post-purchase flows: thank-you emails with cross-sell suggestions, replenishment reminders for consumable products, and win-back sequences for lapsed customers.

Bottom Line on Recovery: Wix's abandoned cart recovery is available on every e-commerce plan and offers multi-step sequences versus Squarespace's single-email approach on the top-tier plan. For any store where abandoned cart recovery is a meaningful revenue channel, Wix's approach is both more accessible (no plan gating) and more capable (multi-step, segmented workflows).
