Head-to-head · September 2026 snapshot

Shopify POS vs Square

Shopify POS leads overall; Square still owns ChatGPT. Shopify POS edges Square on the category Visibility Score, 79 to 74, and the gap comes almost entirely from Gemini, where Shopify POS scores 84 against Square's 70.8. The one question theme where any brand differentiated itself, the single-pick scenario, went to Shopify POS, while Square matched or beat it on every other theme. Square's only real foothold is ChatGPT, where it leads 79 to 78, a margin thin enough that one update cycle could erase it.
