Stripe vs Square Fees
Scenario math for trades—not a duke-out over logos. Compare effective rate, channels, and add-on lines before you switch.
Last updated: March 2026
Headline processing rates rarely predict net deposits. Stripe and Square both stack fees from cards, hardware, instant payouts, and optional products—your job is to model the bundle you will actually run for 90 days, then divide total fees by volume.

Start with channel mix
Weight economics by how you actually collect.
List percentages are useless until you know how much volume is card-present, invoiced, or checkout. A plumbing company with 70% van swipes should weight Square-style economics; a design-build firm with 70% online deposits should weight Stripe.
Stripe: where fees accumulate
Core cards plus modules you might enable.
Core card charges are table stakes; Stripe Billing, Terminal hardware, Connect, and currency conversion add lines. That is not bad—just insist on a spreadsheet that includes every module you will actually turn on this quarter.
Square: hardware and software bundles
Hardware, software tiers, and instant transfer.
Processing is one row; Instant Transfers, paid software tiers, and replacement readers are others. Owners love simplicity until they forget to model instant transfer on busy Fridays—rebuild cash-flow with and without it.
Micro-tickets vs whale tickets
When flat rate vs interchange-style math flips.
Flat rate can win on small average tickets where interchange would otherwise dominate; interchange-plus can win when your mean ticket crosses into replacement territory. Use your accounting system’s job export to compute true means, not gut feel.
Cross-check with invoicing
Avoid counting the same cost twice.
If invoicing software charges its own payment fee, avoid double-counting when comparing processors—some stacks hide fees in two vendors.
