E-commerce
Sell physical and digital goods.
Three different products hide under one category. Shopify and WooCommerce run the whole storefront; Snipcart and Reflow bolt a cart onto a site you already built; Medusa, Saleor and Vendure are backends you assemble a store on top of. Digital goods change the math again, since Lemon Squeezy sells as merchant of record and takes cross-border tax off your desk.
Editor's pick
Selling downloads or licences? Start with Lemon Squeezy and skip the tax registration work entirely. Snipcart when the site already exists and only checkout is missing.
