Shopify POS and Square POS are two of the most widely considered point of sale platforms for small and medium businesses, and they both do a lot right. The problem is that they are designed around fundamentally different business models, and choosing the wrong one wastes months of setup time before the mismatch becomes obvious.

This guide gives you the full picture across every dimension that matters: pricing, hardware, features, the specific business types each one serves well, and the questions that should drive your decision. By the end, you will know exactly which one fits your operation.

Who Each Platform Is Built For

The Single Most Important Thing to Understand

Shopify POS: Built for Retail Businesses That Also Sell Online

Shopify POS is an extension of Shopify’s e-commerce platform into physical retail. If you run or plan to run both a physical store and an online shop, Shopify POS is designed precisely for you. Your inventory, your customer profiles, your order history, and your analytics are all unified across both channels from day one. A customer who bought something on your website shows up in your in-store system. A product sold in store is automatically deducted from your online inventory.

For businesses operating only in physical retail with no e-commerce plans, Shopify POS is functional but you are paying for and carrying infrastructure you will not use.

Square POS: Built for Simplicity Across Any Business Type

Square POS is a general-purpose platform serving retail, restaurants, service businesses, and e-commerce, designed around ease of setup, transparent pricing, and minimal friction. It is not the most powerful option in any single category, but it is consistently good enough across most categories and genuinely excellent for businesses that want a straightforward, no-surprises payment and sales system without committing to a complex ecosystem.

Pricing: The Full Picture

What You Will Actually Pay

Square Pricing

Square’s pricing is unusually transparent. The free POS software covers most small business needs. Processing fees are published flat rates: 2.6 percent plus 10 cents per in-person tap, dip, or swipe transaction for the free tier. There are no monthly fees, no long-term contracts, and no surprise charges for the core POS functionality. Paid plans (Square Plus and Square Premium) add advanced features at published monthly prices.

Shopify Pricing

Shopify charges a monthly subscription fee that depends on your plan, starting at $29 per month (Basic) and going up through Shopify ($79/month) and Advanced ($299/month). Processing fees decrease as you move up the plan tiers: Basic charges 2.7 percent in-person, while Shopify and Advanced charge 2.5 and 2.4 percent respectively. Shopify POS Pro, required for full in-store POS capabilities, is an additional $89 per month per location. If you use a third-party payment processor instead of Shopify Payments, you also pay an additional transaction fee.

Hardware

What You Need and What It Costs

Square Hardware

Square offers the free magstripe reader to get started, the Square Reader for contactless and chip at $49, the Square Terminal (standalone device with built-in printer) at $299, the Square Stand at $149, and the full Square Register at $799. Hardware works with the free plan and you own it outright with no mandatory leasing.

Shopify Hardware

Shopify sells the Shopify Card Reader at $49, the Shopify POS Terminal at $399, and the Shopify POS Go (a dedicated Android device) at $399. Shopify’s hardware ecosystem is smaller than Square’s but is purpose-built for Shopify’s software. The key difference: Shopify hardware requires a Shopify subscription to function, while Square hardware can work with the free plan.

Features: Where Each Platform Leads

The Category-by-Category Breakdown

Inventory Management

Shopify wins this category decisively for businesses operating across both channels. Businesses looking for a fully integrated POS system often choose Shopify for its unified inventory and customer management capabilities. Real-time inventory synced between online and in-person, variants management, purchase orders, and supplier management are all significantly more advanced in Shopify than in Square. For a retail business selling the same products online and in-store, this unified inventory is the most practical argument for Shopify POS.

Square’s inventory management is solid for single-channel retail but lacks the depth of Shopify’s multi-channel approach.

Customer Management and CRM

Both platforms maintain customer profiles and purchase history. Shopify’s advantage is that the customer profile spans the full Shopify ecosystem, capturing online behavior, wishlist activity, abandoned carts, and in-store purchases in a single unified record. Square’s customer management is competent but primarily in-store focused.

Reporting and Analytics

Shopify’s analytics are more comprehensive and more granular, particularly for businesses wanting to compare in-store and online performance, understand customer behavior across channels, and track product performance by channel. Square’s reporting is clean and accessible but less deep for multi-channel analysis.

Ease of Setup and Use

Square wins here. Getting started with Square POS takes under an hour: download the app, plug in the reader, and you are taking payments. Shopify POS requires setting up a full Shopify store first, which involves more configuration even for a business that only wants to use the in-store POS. For businesses that just want a fast, simple payment solution, Square’s frictionless setup is a genuine advantage.

Who Should Choose Which

The Decision Made Simple

Choose Shopify POS If…

  • You sell products both online and in physical retail, or plan to — this is Shopify’s core strength
  • Unified inventory across channels is a must-have operational requirement
  • You are already on Shopify for e-commerce and want your in-store operation in the same ecosystem
  • You want deep customer profiles that capture both online and in-store behavior
  • You are running or planning to run multiple physical locations alongside e-commerce

Choose Square POS If…

  • You operate a single physical location or a service business with no significant e-commerce
  • You want transparent, predictable pricing with no monthly subscription commitment
  • Quick, simple setup matters more than advanced feature depth
  • You run a cafe, food truck, market stall, or service business where Square’s broad versatility is an advantage
  • You want to avoid being locked into a specific ecosystem and prefer flexibility to switch later

Final Thoughts

Shopify POS and Square POS are both strong platforms that serve their target users well. The choice between them is almost always determined by one factor: do you sell online and in-person, or just in-person? If both channels matter, Shopify’s unified commerce infrastructure is worth the higher cost. If you are operating purely in physical retail or a service context, Square’s simplicity, transparent pricing, and no-contract model typically wins on value.

FAQs

1. What is the main difference between Shopify POS and Square POS?

Shopify POS is built for businesses that sell both online and in physical retail, with inventory, customers, and analytics unified across both channels. Square POS is a general-purpose platform that works well for any business type and is strongest for simplicity, transparent pricing, and ease of setup.

2. Which is cheaper, Shopify POS or Square POS?

Square is cheaper for most single-location businesses because it has a free functional tier and no mandatory monthly subscription. Shopify always has a monthly cost, and adding POS Pro for full in-store capabilities adds $89 per month per location. For businesses also running e-commerce, Shopify’s consolidated cost may be better value overall.

3. Can Square POS handle online and in-person sales?

Yes, Square Online provides e-commerce functionality that integrates with Square POS, but the integration is less seamless than Shopify’s native multi-channel setup. For businesses where both channels are significant, Shopify typically provides a better unified experience.

4. Does Shopify POS work without Shopify e-commerce?

Technically yes, but it requires a Shopify subscription even if you only use the POS. This means you are paying for e-commerce infrastructure you may not use. Square has no equivalent cost for businesses that only want in-person POS.

5. Which POS is better for a small retail store?

For a small retail store with no online sales, Square is usually the better starting point: no subscription fee, faster setup, and lower total cost. If the store also sells online or plans to, Shopify’s unified inventory and customer management typically justify the higher cost.
