Square Review

Square offers simple, transparent payment processing ideal for small businesses. Flat-rate pricing, no monthly fees, and excellent software make it a top choice — but account holds and limited support are key concerns.

Estimated annual cost at three realistic processing volumes, using Square’s published online rate plus monthly fees. Real costs vary with average transaction size, chargeback rate, and any negotiated terms.

How Square pricing works

Square is the archetypal flat-rate processor: every card transaction of a given type costs the same percentage plus a fixed fee, with no monthly fee, no contract, and no early-termination charge for core processing. You pay only when you process. What has changed is that the flat rate is no longer a single number. Square now sells three plans, and both the in-person rate and the online rate depend on which one you are on: paid plans trim in-person processing to 2.5% or 2.4% + $0.15, while free-plan sellers taking money through Square Online or Square Invoices pay 3.3% + $0.30 rather than the 2.9% + $0.30 that Square is still best known for. That 2.9% now applies only to the Payments API, or to online and invoice payments on Plus and Premium.

Payouts and the account-hold trade-off

Standard payouts arrive the next business day — quick for the industry — and instant transfers are available for a 1.95% fee. The flip side of Square's instant onboarding is that underwriting happens after you start processing, and the consequence shows up in its reviews: holds and frozen funds are the overwhelming complaint theme, typically triggered by volume spikes, unusually large transactions, or activity that looks high-risk. Combined with support that merchants describe as hard to reach, a hold can be genuinely painful. Steady, low-risk businesses rarely encounter this; anyone with irregular volume should keep it in mind.

What to pin down before you sign

There is no contract to negotiate, so the checklist is short, but the first item now matters more than it used to: work out which plan you are on and which channel your money actually arrives through, because an online sale costs 3.3% + $0.30 through Square Online on the free plan and 2.9% + $0.30 through the Payments API. If most of your volume is e-commerce, price the $49 Plus plan against what the lower online rate saves you. Then price out the add-on subscriptions you will really use (many features beyond core POS are paid), know that keyed-in transactions cost 3.5% + $0.15 before you rely on them, and read Square's terms on holds and reserves so a funds review does not catch you with payroll due.
