Square
Start taking card payments today; build out the rest of the business later.
What is Square?
Square is a payments and point-of-sale platform that started as the white card reader you plug into a phone and has grown into a full operating system for small retail, restaurants, and service businesses. The unique thing is there's no monthly fee to start taking payments, no underwriting drama, and the hardware lineup goes from a free magstripe reader to a full countertop terminal. Same-day deposits to a Square checking account are included.

Business fit
Right for you if you're a single-location retailer, cafe, salon, food truck, or service business doing under roughly $250K/year in card volume and you value a fast setup over the lowest possible processing rate. Skip it if you're processing more than ~$500K/year (negotiated rates from Stripe, Toast, or a traditional processor will beat Square), if you're a high-volume restaurant with complex coursing and multiple revenue centers (Toast is built for that), or if you need ecommerce subscriptions and developer APIs (Stripe is the better tool). Square is famous for freezing funds when transaction patterns look unusual, so high-ticket or seasonal businesses should plan for that.
How to evaluate Square
Use this category when operational data, policies, tasks, or internal requests are spread across disconnected systems.
Confirm the exact workflow
Map Square to one concrete workflow first, such as taking in-person card and contactless payments at a counter, market, or pop-up. Avoid buying before the owner, trigger, output, and success metric are clear.
Check category fit
Compare internal search, permissions, workflow support, and reporting.
Compare practical alternatives
Shortlist Square against Glean, Guru, Slite so the decision is based on fit, effort, and workflow ownership rather than brand recognition alone.
Validate cost and rollout effort
Three plan tiers determine the rate. Square Free is $0/mo and charges 2.6% + 15 cents in person, 3.3% + 30 cents online, 3.5% + 15 cents for keyed or card-on-file, and 1% (min $1) on ACH invoices. Square Plus runs 2.5% + 15 cents in person and 2.9% + 30 cents online with a $10 cap on ACH. Square Premium drops in-person to 2.4% + 15 cents. Hardware is separate: the basic reader is free, terminals run a few hundred dollars. Payroll, marketing, loyalty, and Square Banking are billed individually. Also confirm implementation time, support needs, and whether the medium setup matches your team.
