Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Increase

  • The published per transaction rates exclude a monthly platform fee that Increase states varies by use case, so the transparent price page cannot produce a total cost and the material part of the deal is still negotiated privately.
  • Free allowances are deliberately small at ten account numbers and five physical cards, so any programme issuing accounts or cards at volume moves to quoted pricing almost immediately.
  • Banking is provided through partner banks, so programme approval, compliance obligations and the ability to launch at all depend on a bank relationship you do not control, and post-Synapse bank risk appetite has tightened considerably.
  • The API deliberately exposes payment rail mechanics rather than smoothing them, which is correct engineering but means a team without payments expertise will build reconciliation and return handling wrongly and only discover it when funds go astray.
  • Coverage is United States only, so a company with international payout needs runs a second provider and reconciles two ledgers, and the single API argument disappears at the first cross border customer.

Square

  • Plus plan pricing not specified in documentation
  • Processing fees differ by tier but exact rates not detailed
  • Free plan pricing mentioned but specific features for Plus unclear
  • Text marketing charged at 3¢ per message after first 500 included

Answered from the vendors’ own pages

Increase: Does Increase publish its pricing?

Partly. Per transaction fees for ACH, wires, RTP, FedNow and cards are listed publicly. The monthly platform fee is not, and it is described only as varying by use case.

Square: Does Square offer a free plan?

Yes, Square's free plan includes an all-in-one POS app, online site builder, item library and inventory tracking, invoicing, appointment scheduling, staff calendars, and checking and savings account access. No subscription fees are charged.

Increase: Who holds the deposits?

Partner banks, not Increase itself. That relationship determines your programme approval, your compliance obligations and your risk if the bank changes appetite.

Square: What does Square Plus add compared to the free plan?

Square Plus adds advanced POS features for food and retail, lower processing fees on card transactions, custom loyalty programs, unlimited email marketing campaigns, text messaging, and staff scheduling and attendance tracking.

Source
Increase: Is it international?

No. Increase covers United States rails only, so cross border payouts require a second provider.

Increase: How is it different from a middleware BaaS platform?

It exposes the rails rather than abstracting them, showing real return codes and settlement timing. That suits teams who understand payments and punishes teams who do not.
