Shopify vs Square: POS and Ecommerce Comparison for Retailers (2027)

Running a retail store across online and in-person channels requires a POS system that keeps sales and inventory organized. Shopify and Square both support these operations, but their checkout features, ecommerce tools, and pricing differ.

According to the National Retail Federation, US holiday retail sales are projected to grow 4.2% in 2026, reaching $1.013 trillion. Retailers need reliable systems to manage transactions and stock across channels.

This Shopify vs Square comparison examines POS features, ecommerce capabilities, inventory management, and pricing. It also covers migration steps and when connecting both platforms makes more sense than switching.

Is Shopify or Square better for a retail store?

Square is generally better for small retailers focused on in-person sales, while Shopify is better for businesses prioritizing ecommerce growth. However, retailers that rely on both channels may benefit from using Square for checkout and Shopify for online selling.

The decision also depends on your existing hardware and future plans. A gift shop with 250 products and mostly walk-in customers may find Square sufficient. An apparel retailer with a large online catalog may prefer Shopify's storefront customization and app ecosystem.

Retailers with established Square hardware and a growing Shopify store can connect both platforms instead of replacing their POS. This allows them to retain their existing checkout setup while managing online sales through Shopify.

What do Shopify and Square each do, and can they work together?

Square and Shopify both support in-person and online retail sales, but their core strengths differ. Square focuses on checkout operations and payment processing, while Shopify offers more extensive ecommerce features. Retailers can use either platform independently or connect them through a third-party integration.

1. Square: A counter-first system with a website built in

Square combines in-person payment processing with POS software and an online store. Its Free plan starts at $0 per month and includes essential checkout features, product management, and a website.

For retailers needing more advanced tools, Square Plus costs $49 per month per location, while Premium costs $149. Both paid tiers offer additional inventory management capabilities, including purchase orders and stock reporting.

Square maintains a shared item library for its POS and online store, allowing retailers to manage product information and inventory from one system.

2. Shopify: An online store with a POS app

Shopify provides an ecommerce platform with tools for managing products and online orders. Its Basic plan starts at $29 per month when billed yearly and includes a POS app for in-person transactions.

Retailers can accept payments using a compatible phone or tablet and a Shopify card reader. For more advanced retail operations, Shopify POS Pro costs an additional $89 per month per location, billed yearly.

POS Pro adds features such as purchase orders, stock counts, and expanded staff management, making it suitable for retailers with more complex in-store operations.

3. Using Shopify and Square together

Retailers do not necessarily need to replace one platform with the other. A business already using Square for in-store transactions can retain its POS while using Shopify to manage online sales.

However, Square and Shopify do not offer a native integration. Connecting them requires a third-party solution to keep product information and inventory quantities synchronized across both systems.

The table below summarizes the main differences between Shopify and Square, including their hardware requirements, inventory capabilities, and integration options.

Table 1: Shopify vs Square comparison of primary features, hardware, starting prices, and integration requirements.

How do Shopify and Square compare at the counter?

Hardware costs and card processing fees are the biggest differences between the two systems for small retailers. Staff management features also vary by subscription plan.

1. Hardware and setup

According to Square's comparison page, its hardware ranges from the Square Reader at $59 to the Register at $899. The Stand ($149) turns an iPad into a counter, and the Terminal costs $299.

Shopify runs on a phone or tablet you supply. Its Tap & Chip Card Reader lists at $49, or $89 with a dock.

Take a gift shop with an iPad already on the counter. Square's Stand runs $149 for that setup, and Shopify's docked reader runs $89, before any scanner or printer.

2. In-person card rates

Square Free charges 2.6% + 15¢ per in-person payment, while Square Plus charges 2.5% + 15¢. Square Premium offers a lower rate of 2.4% + 15¢ per transaction.

With Shopify Payments, Basic charges 2.6% + 10¢ in person. On a $40 sale, Square Free takes $1.19 and Shopify Basic takes $1.14. Across 300 such sales per month, Shopify's lower fixed fee saves $15.

3. Staff and checkout tools

Shopify Basic provides POS access to a limited number of staff members. POS Pro adds unlimited staff accounts with permissions, which suits a shop with weekend part-timers.

Square Plus adds staff management to its retail POS, according to Square's October 2025 pricing announcement. Compare the pricing tiers that include the tools your store needs. Our guide to selling at the counter and online covers checkout setups in more depth.

How do Shopify and Square compare for selling online?

Shopify gives a growing web store more themes and apps, while Square's online store uses the same item library as its POS system. Online sales reached 17.1% of US retail in Q2 2026, per FRED, so retailers should evaluate ecommerce capabilities separately from in-store POS features.

1. Storefront and add-ons

Shopify offers more than 100 professional themes and thousands of apps for customizing online stores. Retailers can also manage product quantities and stock settings through Shopify, as covered in our Shopify inventory management guide.

Square's website builder comes with Square Free, and online orders draw on the same item library as the register. A candle shop selling 40 popular products can manage its online sales through Square. A brand planning to offer subscriptions and wholesale purchasing may benefit from Shopify's broader app ecosystem.

2. Online card rates

Online payments on Square cost 3.3% + 30¢ on Free and 2.9% + 30¢ on Plus or Premium. On $5,000 of online card sales per month, that 0.4-point difference comes to $20, less than Plus's $49 fee.

Shopify's Basic plan matches the 2.9% + 30¢ rate with Shopify Payments. Keeping another payment provider adds a 2% Shopify fee on Basic.

3. Pickup and shipping

Shopify lists in-store pickup and ship-from-store among its tools for selling across channels. Square offers pickup and delivery through its website, according to its comparison page.

A toy store can offer same-day pickup through either platform. Shipping zones and rates need setting up on whichever platform holds the website.

How do Shopify and Square handle inventory?

Purchase orders and stock counts depend on the plan tier in both systems. The plan you choose matters more than the platform's name.

1. Products and variants

Square keeps one item library with variations, shared by the register and the website. According to Shopify, each product supports up to three options and 2,000 variants.

A T-shirt in five sizes and four colors makes 20 variants to track. Every variant needs its own SKU (stock-keeping unit) and inventory count in either system.

The plan grid below shows where each tool sits.

Table 2: Inventory management features across Square Free, Square Plus or Premium, and Shopify POS Pro.

2. Counts and purchase orders

Basic item and catalog management comes with Square Free. Plus and Premium add purchase orders and vendor profiles. Barcode labels and unit-cost reports come with those tiers too.

Shopify puts counts and purchase orders inside POS Pro, together with low-stock alerts. Inventory tracking capabilities can also affect third-party integrations, making plan selection important. For example, SKU IQ supports Square Plus or Premium but does not support Square Free.

3. A second location

Square Free allows retailers to add locations at no extra cost. However, transferring inventory between locations requires Square Plus or Premium, with subscription fees charged for each active location.

Shopify charges $89 per month for each POS Pro location. A sporting goods retailer with two locations pays $98 per month for Square Plus, compared with $178 for two Shopify POS Pro locations, excluding the Shopify subscription. Our guide to ecommerce inventory management shows how to keep stock accurate in both places.

What do Shopify and Square cost a small retail store?

Software for one location runs from $0 on Square Free to $118 per month for Shopify Basic with POS Pro, billed yearly. Hardware and card processing fees are additional.

The total cost depends on whether you use one platform for both sales channels or connect Square and Shopify. The table below compares software costs for three retail setups, assuming one location and one register.

Table 3: Software costs for Square, Shopify, and a connected setup, excluding hardware and payment processing fees.

Retailers with paid-off Square devices generally spend less by staying on Square. Moving to Shopify may require a card reader starting at $49, plus a compatible dock or stand.

A Shopify-only shop can hold off on POS Pro until it needs counts and purchase orders. That drops its software bill to $29 per month on yearly billing.

As transaction volume increases, payment processing fees can exceed monthly software subscription costs. Run both rate tables against last year's monthly card sales before you sign anything.

How hard is it to move between Shopify and Square?

Reformatting product files and importing accurate inventory counts are often the most time-consuming parts of migration in either direction. Hardware and staff training follow close behind.

1. Moving from Square to Shopify

Shopify's migration guide starts with an export of the Square item library to CSV. Each Square column then maps to Shopify's product template, so "Item Name" becomes "Title".

Run a test import of 5 to 10 products before the full file. One location's stock loads in the same file, while two or more locations need a separate inventory file. Customers move by CSV, while order history and reviews need apps from the Shopify App Store.

2. Moving from Shopify to Square

Square's bulk import tool loads items from its own spreadsheet template into the item library. Download the blank template and paste in your Shopify product data, then upload it from the Square Dashboard.

The "New Quantity" column sets inventory quantities for each location. Entering zero sets that location's stock count to zero. Check SKU columns carefully in Excel or Google Sheets, as spreadsheet applications may remove leading zeros from SKUs.

For a 900-item apparel store, most of the work involves matching columns and checking every size and color variant. Larger sellers can get help moving Shopify data into Square, according to Square's comparison page.

The migration steps differ depending on which platform you're moving to. The table below compares how key retail data and hardware are handled in each direction.

Table 4: Data transfer and hardware requirements when switching between Shopify and Square.

3. Hardware and launch day

Square card readers cannot be used to process payments through Shopify POS. However, some existing peripherals, such as receipt printers and barcode scanners, may be compatible. Check Shopify's hardware compatibility requirements before replacing your equipment.

Count inventory the evening before launch and upload the final quantities last. Pick a quiet week such as mid-January, and train staff on the new register before it opens.

4. Copying products without a spreadsheet

As explained in SKU IQ's bulk push documentation, a connector can transfer product catalogs from Square to Shopify or vice versa. A bulk push of up to 1,000 items costs $200, and paid plans include batch pushes of 50 items at a time.

The free trial allows retailers to push up to 50 items, enough to test one product category before transferring the remaining catalog.

When should you keep Square and connect Shopify?

Consider keeping Square if most of your revenue comes from in-person sales and you already own compatible Square hardware. Add Shopify for the online store, then connect the two so each sale updates stock in both places.

In Alchemer's 2026 Holiday Shopper Report, 19.2% of US shoppers expected an even mix of store and online buying. Retailers serving customers across both channels need consistent inventory counts in both systems.

1. Signs the connected setup fits

Check your store against these signs:

• Sales: most revenue still rings up at the counter
• Hardware: Square devices owned outright
• Staff: a team trained on Square's register
• Website: Shopify selected for its themes and apps

2. What the connection needs

Square needs Plus or Premium with inventory tracking switched on. Your Shopify plan needs stock tracking plus support for third-party apps.

Products must share the same structure on both platforms. A single Square item links only to a single Shopify product, as the Square and Shopify integration page explains.

Order syncing can also transfer online orders from Shopify to Square in one direction. Those copies usually arrive within 30 minutes, while stock updates run separately and help prevent the same item selling twice.

Which setup fits your store?

Match your store to the closest profile below, then take the step listed beside it.

• Gift shop with 250 items and mostly walk-in sales: Stay on Square Free and add the Square website for local pickup.
• Apparel brand with 1,800 variants and half its sales online: Price Shopify with POS Pro and plan the move for a quiet month.
• Home goods store with paid-off Square devices and a new Shopify site: Keep Square at the counter and connect the two.
• Sporting goods store with two Square locations: Ask about a multi-location setup before you connect Shopify.

Both platforms offer opportunities to test their services before committing to a paid plan. Check Square's and Shopify's official pricing pages for current free trials, introductory offers, and subscription terms.

Supported pairs appear on the SKU IQ for Square and SKU IQ for Shopify pages. Each page lists the online stores that connect to that system.

How can SKU IQ simplify inventory management in a Shopify vs Square setup?

Managing separate sales channels becomes easier when product updates follow a consistent process. SKU IQ provides a central dashboard for monitoring connected products and reviewing synchronization activity without checking each platform separately.

Retailers can use SKU IQ to manage day-to-day inventory tasks through these features:

• Product visibility: Review connected and unmatched items through the Link Report to identify products that need attention.
• Inventory updates: Stock quantities sync in both directions, averaging about three minutes per update.
• Catalog management: Add products to the other platform using SKU IQ's product push feature.
• Sync monitoring: Review connection activity and identify product issues before they affect daily operations.

SKU IQ offers a 14-day free trial with access to its features and a free setup call. Retailers comparing Shopify vs Square can explore how SKU IQ works or start a free trial to test their connected setup.
