The Quick Answer
Choose Square for most pop-ups and new specialty shops—it's easy to set up, affordable, and great for quick payments at craft fairs or markets. Choose Shopify POS if you mainly sell online but want to add pop-ups or a physical store—it links your online store and in-person sales seamlessly. Choose Lightspeed Retail if you have a complex inventory, multiple locations, or plan serious growth—it offers powerful tools for detailed tracking and reporting.

When to Choose Square
You are launching your very first pop-up, selling at craft fairs, or need to take payments on the go. You want an easy-to-use system that gets you selling in minutes with minimal setup time. Your budget is tight, and you appreciate the free POS app and affordable hardware like the Square Reader. You need basic inventory tracking and customer contact information, but not deep analytics. You might eventually want a simple online store that works well with your in-person sales. Think small craft businesses selling handmade jewelry or resellers with limited stock.
When to Choose Shopify POS
You already have an online store built on Shopify, or plan to create one, and want to link all your sales seamlessly. You need robust inventory management that syncs across your website and physical locations, preventing overselling. You want to offer features like online purchasing with in-store pickup, loyalty programs, or gift cards that work both online and offline. You plan to grow your pop-up into a permanent boutique or a chain of stores. You value strong analytics on both your online and in-person customer behavior. This is ideal for a growing boutique clothing shop or an art gallery doing pop-up exhibitions.
When to Choose Lightspeed Retail
Your specialty shop has complex inventory with many variants (sizes, colors, materials) or unique items that need serial numbers. You manage multiple vendors or consignors and need detailed tracking for payouts and reports. You operate more than one physical location and need to manage inventory, staff, and sales across all of them from one system. You require advanced reporting to understand sales trends, profit margins, and inventory turns for specific product categories. You need features like purchase order management, vendor returns, or repair services built into your POS. This suits a vintage reseller with unique, detailed inventory, or a multi-vendor consignment shop.
The Verdict
Square is the default for most new pop-ups and specialty shops, especially if you prioritize ease of use and low cost for getting started with payments. Shopify POS makes sense when your business strategy is hybrid (online and physical) and you need strong, unified inventory and customer data across all channels. Lightspeed Retail only wins if your inventory is complex, you manage multiple locations, or you have unique operational needs that require powerful, specialized retail management tools.
