Best POS Systems for Pop-Up Shops & Craft Vendors: Square vs. Shopify vs. Lightspeed
The point-of-sale (POS) system you pick for your specialty retail or pop-up shop shapes how fast you sell, how well you track inventory, and your overall costs. Square, Shopify POS, and Lightspeed Retail each handle payments and inventory differently. The wrong choice can lead to lost sales, inventory headaches, or hundreds of dollars in extra fees per year.

The Quick Answer
Choose Square POS if you want free POS software and a simple way to accept payments and track basic inventory for your craft fair booth or first pop-up. Choose Shopify POS Lite if you already have an online Shopify store and need a quick, easy way to sync in-person sales and inventory. Choose Lightspeed Retail if you are building a full-time physical boutique, manage complex inventory, or need advanced staff and customer tools.
Side-by-Side Breakdown
Square POS: Free POS software, card readers from $10-$299 (Square Reader for contactless and chip is $49), payment processing at 2.6% + 10¢ per tap/dip/swipe. Strong basic inventory tracking, easy mobile use with a phone or tablet. Best for getting started quickly. Shopify POS Lite: Included with any Shopify e-commerce plan ($29-$299/month for the online store). Payment processing through Shopify Payments starts at 2.9% + 30¢ for Basic plans, decreasing with higher-tier plans. Hardware sold separately (card readers from $49). Ideal for syncing online and offline sales and customer data. Lightspeed Retail: $89-$199/month (billed annually) for POS software, plus payment processing fees (often 2.6% + 10¢ or negotiated rates). Offers advanced inventory management (matrix, kits), detailed reporting, vendor management, and staff permissions. Requires more setup, often used with dedicated hardware like receipt printers and barcode scanners.
When to Choose Square POS
You are launching your first pop-up shop, selling crafts at a market, or testing a new product line and need to keep costs low. You already have a phone or tablet and need a reliable card reader for secure payments. You need simple inventory tracking to avoid overselling your unique items or small batches. You expect to mainly sell in-person and want predictable, per-transaction payment fees without a monthly software bill.
When to Choose Shopify POS Lite
You primarily sell online through Shopify and want to expand into pop-up markets without managing separate inventory. You need all sales (online and in-person) to update your single Shopify inventory count automatically. You want to see a unified view of customer purchases, whether they bought from your website or your booth. You are comfortable with your existing Shopify plan's monthly cost and payment processing rates.
When to Choose Lightspeed Retail
You are establishing a permanent or long-term specialty retail store and plan to grow. You manage complex inventory, like apparel with multiple sizes/colors (matrix inventory), or need to track components for custom items. You have multiple staff members who need different access levels for sales, refunds, or inventory adjustments. You require detailed sales reports to understand trends and optimize purchasing for your boutique.
The Verdict
For first-time craft vendors or pop-up entrepreneurs, Square POS offers the lowest-risk starting point with its free software and transparent payment fees. For online sellers looking to easily add in-person events, Shopify POS Lite is the best for seamless inventory and customer data. For established physical stores with advanced inventory and staff needs, Lightspeed Retail provides the robust features required for growth. Do not pay for a full-featured system like Lightspeed until your sales volume and inventory complexity justify the higher monthly cost.
How to Get Started
Square POS: Sign up for a free account, order a Square Reader for contactless and chip ($49), and download the Square Point of Sale app to your phone or tablet. You can accept payments and track sales immediately. Shopify POS Lite: If you have an active Shopify store, simply enable Shopify POS Lite from your admin panel, download the Shopify POS app, and order a card reader. Your online products will automatically be available for in-person sales. Lightspeed Retail: Start a free trial, use their onboarding wizard to upload your initial product catalog, and connect a supported payment processor. Plan for 1-2 hours of setup time for basic inventory and payment integration.

FREQUENTLY ASKED QUESTIONS
Can I migrate courses between platforms?
Video content can be re-uploaded, but student enrollment records, progress data, and completion certificates do not transfer cleanly. Migrating 100+ students is a manual process. Choose carefully before you have a large student base.
Does Kajabi replace ConvertKit?
Kajabi's email is capable for most creators, but ConvertKit has stronger automation tagging, deliverability, and creator-specific features. Some creators use both — Kajabi for courses, ConvertKit for email — though that adds cost.
What transaction fees does Teachable charge?
On the free plan, Teachable takes 10% plus payment processor fees. On the Basic plan ($59/month) the fee drops to 5%. On Professional ($159/month) and above, there are no transaction fees.
