You can’t set up an online store on Shopify Lite, but you can embed Buy Buttons on an existing website or blog and send email invoices.
Basic Shopify is the least expensive option with online store capability, 24/7 phone support and an online card processing rate of 2.2% + 20p. The Shopify package throws in professional reports for better analytics, allows more shop locations, more user accounts and a lower online transaction rate of 1.9% + 20p.
The pricier Advanced Shopify includes custom report creation tools, customer analytics, real-time calculated carrier shipping, up to 15 staff and the lowest possible rate of 1.6% + 20p per ecommerce transaction.
If you have a high turnover, the lowered processing rates with Shopify and Advanced Shopify might be worth the extra cost alone.
All of these plans let you download the Shopify POS app and use the free Shopify POS Lite features. But to access all POS features, you need to subscribe to Shopify POS Pro for US$89 + VAT/month per location.
