Square Online: the free way to start a shop
Links on this page go to the company's own website. We do not currently earn from them. If that changes, this page will say "Ad" here and beside the link.
In short
A free-to-start online shop builder tied to Square payments and card readers. Good for small or local sellers, such as market stallholders, who want no monthly fee.
What it costs
- Free plan: £0 a month. Online card fees are 1.4% + 25p for UK cards and 2.5% + 25p for non-UK cards. One third-party review says the free plan does not take PayPal; we could not confirm it (Expert Reviews).
- Plus: £20 a month billed annually. Premium: £64 a month billed annually, with 1.4% + 15p. The monthly-billing price is not shown on the page.
- No trial; the free plan is the way in.

Suits
Very small or local sellers, and anyone who wants to start with no monthly cost.
Does not suit
Sellers wanting wide design control, or a payment provider other than Square.
What reviewers complain about
Trustpilot shows 3.6 of 5 from 7,516 reviews, 13% one-star. Many reviews concern Square payments generally, not only the shop builder. Trustpilot does not fact-check reviews. Themes, paraphrased:
- Accounts frozen or closed with little explanation.
- Held or delayed funds, and support that is mostly a bot.
