| Pricing | $35/month (Mercury Plus), or $29.90/month billed annually · free tier: $0/month Mercury plan: checking and savings, free domestic and international USD wires, virtual and physical debit cards, corporate credit cards, security protocols; expense reimbursement capped at 5 active users/month | Not published — Square Plus is paid per active location; exact per-location dollar figure not confirmed on the vendor plans page · free tier: Square Free — no monthly subscription cost; you only pay processing fees when you take a payment, with all POS modes and Square Banking included |

| Best for | US-incorporated startups and SMBs, especially VC-backed and multi-entity businesses, that want free checking and wires, a strong UI and a high sweep-based insurance ceiling for operating cash. | Single-location or few-location retail, food and service sellers who already use or want Square in person, need one catalogue and one payout account, and want to launch a store at zero subscription risk. |
| Avoid if | You cannot survive a sudden unexplained account freeze, have a non-US or hard-to-document structure or third-party payment flows, need phone support, want yield on idle cash, or are a heavy expense-management user. | You run many locations (per-location billing multiplies the cost of one website), you need deep template and brand control for a design-led DTC store, you take heavy international card volume, or you want payments decoupled from your site platform. |

A higher TOP SCORE means more of the evidence favours that platform on this methodology — it is not a recommendation, and it does not account for your specific requirements. Advertisers are never declared the winner of a comparison.
