Understand the arithmetic of the harm, because Square’s primary base is exactly the businesses least able to absorb it. Hold $25,000 from a corporation and you have created a memo. Hold $25,000 from a small business and you may have taken payroll, this month’s inventory, and the rent, simultaneously, with no person to call and no date certain for release. And the damage compounds, because standing up a replacement processing relationship takes days to weeks, so the revenue stays dark while the bills do not. One account reported directly to us, by a vendor to our own firm: a hold on the scale of tens of thousands of dollars that the owner describes as nearly ending the business, and that forced him to change bank accounts entirely, a step merchants in this position take for a reason the fine print explains: the documented terms permit debits from linked bank accounts without prior notice. When leaving the platform requires leaving your own bank account, the word for that is not friction.

Square has no ISO network and no commissioned field reps, which eliminates the entire category of documented abuse that plagues the legacy processors, and the score credits that structural choice. The deduction is for the gap between the marketing and the mechanics: a signup flow that approves a business in minutes and marketing built on speed and simplicity, paired with terms granting the discretion documented throughout this page. The most painful documented cases follow one arc: approved instantly, encouraged to collect payment, then judged ineligible after the money arrived. An underwriting decision that happens after the sale is not disclosure. It is a trapdoor.

Block’s own annual report describes Square as an integrated operating system for local commerce, with Square as the merchant of record on the payments flowing through it. Read that as a merchant: the processor is fused to the point of sale, the inventory system, the appointments calendar, the payroll, and the banking, so firing the processor means replacing the operating stack of the business. The distribution widens through platform deals: SEC filings document that Square was made the primary and exclusive payment processing partner for an entire event platform’s sellers, meaning thousands of businesses processed on Square by their platform’s decision, not their own. In our professional opinion, a merchant who arrives through an ecosystem default or a platform’s exclusivity agreement is not a client who was won; they are volume that was routed, and pricing discipline follows courtship, not capture. The deduction here reflects both the documented post-sale underwriting pattern above and a distribution model in which a growing share of merchants never made a processor decision at all.
