When to Choose Stripe
Choose Stripe if: - You operate a hybrid retail model, selling both online through a custom website and in-person at a pop-up, needing unified payments and reporting. - You want to integrate payment processing into a unique setup, like a self-serve kiosk for artisan goods or a custom-built mobile retail truck. - You need a specific type of card reader or payment flow that dedicated POS systems might not offer, like a built-in terminal for a point-of-sale display. - You're comfortable with a bit more technical setup for potentially lower per-transaction fees, especially if your average transaction value for handcrafted items or vintage finds is higher. - You want to handle your own inventory and customer relationship management (CRM) through other specialized tools, using Stripe purely as your payment processor.
When to Choose Square
Choose Square if: - You are just starting out with your craft booth, flea market table, or first pop-up, and need a payment system that's easy to set up and use on day one. - You need mobile payment processing that works anywhere, often on your smartphone or tablet, perfect for outdoor markets or temporary setups. - You want a simple, affordable card reader solution, like the basic Square Reader, without committing to expensive hardware upfront. - Your primary focus is taking in-person payments efficiently, managing basic inventory, and seeing quick sales reports, ideal for reseller goods or handmade items. - You appreciate an all-in-one solution that bundles basic POS, payment processing, and even a simple online store if you decide to expand.
When to Choose Shopify POS
Choose Shopify POS if: - You already have an online store built on Shopify for your boutique, consignment items, or art prints, and want to seamlessly bring that inventory and customer data to your physical pop-up. - You need robust inventory management that syncs automatically between your online shop and physical location, tracking specific variants (sizes, colors) of your products. - Your specialty retail business offers gift cards, loyalty programs, or in-store pickup, and you need a system that handles these features smoothly across all sales channels. - You want advanced reporting that combines your online and in-person sales data to get a full picture of your retail performance. - You are growing beyond a simple setup and need features like staff management, exchange/return processing, and dedicated retail hardware options for a more polished customer experience.

FREQUENTLY ASKED QUESTIONS
What is a merchant of record?
A merchant of record is the legal entity that processes the transaction and is responsible for tax collection and remittance. When Lemon Squeezy or Paddle is your merchant of record, they handle VAT, GST, and sales tax on your behalf — you just receive payouts.
Is Lemon Squeezy's 5% fee worth it?
On $100,000 in revenue, the difference between Stripe's 2.9% and Lemon Squeezy's 5% is approximately $2,100. If avoiding global tax compliance saves you more than $2,100 in accountant fees and registration costs, yes it is worth it.
Can I switch from Stripe to Lemon Squeezy later?
Yes, but migrating active subscriptions requires coordination — subscribers may need to re-enter payment details. Plan your platform choice before you have a large recurring subscriber base.
