Square review: simple to start and easy to leave, with real hold risk

First, our relationship: BatchOut, the card processing service run by the team behind Business Funders, is a Square dealer and earns money when a business signs up for Square through it. We scored Square with the same six criteria and the same anchors we use for every processor, and that score is 3.2. Our lists may still place Square first as our pick; when they do, the list says so and repeats this disclosure.

Square is a payment facilitator, not a bank and not a traditional merchant account. Its own terms say: "Square is a payment facilitator that allows you to accept Cards from customers for the payment for goods and services. We are not a bank" [5]. In practice, a facilitator signs you up under its own setup with the card networks, so approval is quick and light, and much of the risk checking happens after you start selling rather than before.

Three things decide whether Square fits. The price is public and simple, but the 15¢ per sale makes it costlier than it looks on small tickets. There is no contract to escape. And the trade for that fast, light sign-up is that Square watches accounts after the fact and can hold money while it checks.

Square charges by plan, and the plan sets your card rate. Square Free is $0 a month, Square Plus is $49 and Square Premium is $149, each per location [1]. Every card brand costs the same within a plan.

Our reference shop does $30,000 a month in card sales, all in person, as 1,200 sales of $25. On Square Free that is 2.6% of $30,000 ($780) plus 15¢ times 1,200 ($180), so $960 a month, or 3.20% of sales [1]. The cards themselves cost about $526.50 in interchange on our Visa-rate model [9], so roughly $433.50 a month is Square's share for that shop. Plus and Premium do not lower that bill unless volume is much higher, because a 0.1% rate cut saves only $30 on $30,000.

• Fees are figured on the whole sale, tax and tip included [3].
• Instant transfers cost 1.95% on top of card fees [4]. Moving $2,000 now instead of tomorrow costs $39.
• New sellers start with one instant transfer a day of up to $2,000 [4].
• Above $250,000 a year, Square invites you to ask about custom pricing [2].

There is no term to sign. Square's pricing page says "No hidden fees or locked-in contracts. Cancel or switch anytime" [1], and its fees article lists early termination among the things Square does not charge for [3]. Paid plans start with a 30-day free trial and can be cancelled at any point [1].

The monthly options are not leases. Square's hardware page says the plans are credit sales issued by Block, Inc., at 15% APR, subject to credit approval, and not offered in six states [6]. If you can pay up front, you skip that interest and own the device on day one. Square sells these devices to run its own software; we found no Square page saying they work with another processor, so plan on leaving them behind if you switch.

This is Square's weakest area. The Payment Terms (last updated July 30, 2026) let Square "withhold funds by temporarily suspending or delaying payouts of Proceeds" or require a reserve "for any reason related to your use of the Services," and add that the reserve "may be raised, reduced or removed at any time by Square, in its sole discretion" [5]. Square may also restrict access to proceeds "temporarily or indefinitely" while it investigates or resolves a dispute [5]. No release date is promised.

On a normal day the money moves fast. Square starts payouts at the end of each business day, before 8 p.m. Pacific, and sends Friday's sales on Sunday [5].

What owners report: we read the three most recent pages of Square's Trustpilot profile on Oct 21, 2026, 63 reviews in all. Two were invited; of the other 61, 24 described held or frozen funds, a reserve, or a closed or deactivated account [8]. That is 39 per 100, above the line where our method gives its lowest score. Recent-review pages lean toward people with a problem, so read this as a warning sign, not a rate of how many accounts get held.

1. Before a large sale, message Square with the invoice, the customer and the job dates. A sale far above your usual ticket is a common trigger.
2. Keep tracking numbers, signed estimates and delivery photos where you can send them within a day.
3. Do not let your bank balance depend on one deposit. Keep a week of costs outside Square.
4. Answer every Square request for documents fast; refusing can lead to suspension or termination under the terms [5].

Phone support depends on what you pay. Square's pricing page lists phone support from 6 a.m. to 6 p.m. Pacific on weekdays for the first 90 days on Square Free, the same weekday hours on Plus, and 24/7 phone support on Premium [1]. Its contact page says phone hours and availability vary by subscription, and that live chat agents work weekdays, 6 a.m. to 6 p.m. Pacific [7]. The number is 1-855-700-6000, with a callback option [7]. Of the 61 organic reviews we read, 17 said they could not get through to a person [8].

The gap between a 78% five-star profile and a 2.5-star organic sample is why we do not take the headline score at face value. Trustpilot marks the profile as one that asks customers to review [8]. We also found a federal action: on Jan 16, 2025, the CFPB issued an order against Block, Inc., which operates both Square and Cash App, over fraud handling at Cash App [10]. It did not concern Square seller accounts, so we note it but do not deduct for it, the same way we treat actions about other product lines at other providers.

• Stripe: the better match if most of your sales are online or run through your own website or app.
• Clover: a counter system sold through many banks, worth a look if you want a bank relationship, as long as you read the hardware terms first.
• Toast: built for restaurants; see Square vs Toast for the full cost comparison.
• Helcim: interchange-plus pricing, the model that tends to pay off as your monthly card volume grows.

Side by side numbers are on Square vs Clover vs Stripe, and every Square fee is broken down on Square fees.
