| Bottom line | From its public pages, Big Cartel is the lowest-cost store here for one person with a small catalog, with no transaction fees and US sales tax handled. It has no staff accounts, so our scenario cannot be priced, and it publishes no PCI, SOC 2 or ISO statement of its own. | From its public pages, Ecwid is a low-cost way to add a store to an existing site, with cart emails, subscriptions and full CSV export from $49 a month. There is no free plan or trial, and whether Lightspeed’s monthly fee for other payment providers applies to Ecwid stores is worth asking. | From its public pages, Shopify has the broadest set of selling features here on the plan our scenario needs, with PCI Level 1, SOC 2 Type II and a 2-year data window. Staff accounts start on Grow, and a store that uses another payment provider pays Shopify a fee on top. | From its public pages, Square Online offers the most complete free start here: a store with unlimited items that takes real orders and shares Square’s POS and payments, with Plus at $49 for a custom domain and cart emails. Live shipping rates need Premium, and payments are in one currency. |
