Square: cost, fit and limits
Square is a point of sale and business software suite made by Block, Inc. that combines a register app, card readers, online sales, invoicing and a beta AI assistant for small and mid-sized sellers. It starts with a free plan and charges for payments when a card is taken.
What to know first
Square works as a ladder with a free first step. The Free plan carries the register app, an online site, an item library, invoicing and booking, and Plus layers on advanced register features, lower processing fees, loyalty and marketing. The pricing page we read shows neither a Plus price nor processing rates, so the real cost is only visible after sign-up. Square AI is separate and labeled beta.

Who Square is best for
Brand-new sellers
The Free plan has no monthly charge, so a seller can open the app, add items and take a first sale before deciding whether any paid layer is worth it.
Owners who message customers
Plus adds email and text marketing, with the first 500 texts free and 3 cents per text after, which suits shops that want loyalty offers without a separate tool.
Restaurants building a menu
Square AI is described as generating menus and item catalogs, and as comparing ingredient prices across suppliers through Order Guide, which helps with setup.
Service businesses
The Free plan lists booking and invoicing next to the register, and Square AI is described as assisting with booking management, so one login can cover appointments and checkout.

What Square does
- Plain-language questions
- Square AI answers questions about your own sales data without report building, and pins generated charts to a workspace where they refresh as new sales arrive.
- Local trend context
- The assistant adds outside signals such as local weather, events, news and reviews to explain a quiet or busy day, according to the AI page.
- Setup help
- Square AI is described as auto-generating menus and item catalogs and assisting migration of service data, which cuts the typing during a first week. A new seller can use this to skip hours of typing, though every generated item should be checked for price and allergens.
- Supplier price comparison
- Order Guide compares ingredient prices across suppliers and can turn a menu into an ingredients list for ordering. This matters most to kitchens that buy from several wholesalers, because the comparison saves phone calls, though you still approve each order.
- Customer messaging
- Square AI lists automated voice ordering, messaging and AI-assisted booking management, plus drafts of marketing copy, team announcements and product images. Treat anything sent to a customer as a draft that a person reads first, especially booking changes and promotional wording that quote prices.
- Hardware range
- Square lists handheld, terminal, register, stand, kiosk and reader categories. Prices were not shown on the pages we read. Hardware choice depends on whether you sell at a counter, a table or a door, so ask for current prices when you sign up.
How Square handles your data
Block, Inc. is based in Oakland, California, and its privacy notice says the Square entity differs by country of residence. The notice states that Square may analyze data that you input, along with commercial information, using AI technologies to create personalized features for your business, relying on contract performance and legitimate interests. It does not say whether personal data trains AI or machine learning models, and it links a separate Square AI Terms of Service that we did not read. Account data is kept while the account exists, and some data may be kept after deactivation for legal reasons.
Where Square falls short in practice
- Cost is hidden until sign-up. The pricing page shows no Plus price, processing rate table or hardware cost, and a trial length placeholder was unrendered. A buyer cannot total the bill from the page.
- AI is beta and unscoped. Square AI is labeled beta. The page does not say which plan includes it, what it costs or how customer data feeds it, so treat it as a preview.
- Terms live elsewhere. The privacy notice refers to separate AI terms. Read them before loading customer lists, since the notice itself gives no training rule. Read them before loading customer lists, and save a copy of the version you accepted.

Alternatives to Square
Square: common questions
Is Square really free to start?
The pricing page says it starts at $0 and that Square Free charges only when you take a payment. It lists a register app, online site, item library, invoicing and booking. Hardware is a separate purchase, and processing fees apply to each card sale.
What does Square Plus add over Free?
The page lists advanced register features, lower processing fees, a loyalty rewards program, email and text marketing and staff management. No Plus price or fee table appeared on the page we read, so confirm both in your account. Compare Plus against Free only after you know your monthly card volume, because the saving depends on it.
Can Square AI order stock for me?
The AI page describes ingredient price comparison through Order Guide and menu-to-ingredient lists. It does not state that the assistant places orders on its own. Check the order screen in a trial to see who approves each purchase. Check the order screen during a trial to see who approves each purchase before it leaves your account.
Does Square use my sales data to train its AI?
The privacy notice says Square may analyze data you enter with AI to generate personalized features for your business. It does not say whether data trains models. Read the separate Square AI terms and ask support for a written answer.
How much do text messages cost on Square Plus?
The first 500 texts are free on Plus, then 3 cents each, according to the pricing page. Email campaigns are listed as unlimited on Plus without a stated price, so a shop that mostly emails customers pays nothing extra for those campaigns on Plus.
