Square
Payments, point of sale and business tools for small and in-person sellers
The verdict
Square gives small businesses card processing, point-of-sale hardware and software, plus booking, invoicing and payroll add-ons. Built for in-person and omnichannel sellers who want tools that work out of the box.
What it is
Square packages payments with everything around them for a small seller: point-of-sale software and hardware, online store and invoicing, plus add-on products for appointments, payroll and marketing. The appeal is that it works without development, so a shop or service business can start taking payments in person and online quickly. The tradeoffs are that it is less programmable than developer-first infrastructure, transaction pricing applies per sale, and its all-in-one breadth can mean paying for product modules that a single-purpose tool would handle more cheaply or deeply.
Strengths
- Payments, point of sale and business tools work out of the box, so a seller starts taking money without development
- Hardware and software cover in-person and online selling, keeping omnichannel sales in one customer directory
- Add-on products for appointments, payroll and marketing let a business grow within one system
Trade-offs
- It is less programmable than developer-first payment infrastructure, so custom billing needs hit limits
- Per-transaction pricing applies to every sale, which high-volume sellers should compare against negotiated rates elsewhere
- Its all-in-one breadth can mean paying for modules a single-purpose tool would cover more cheaply or deeply
Best for
Taking in-person and online payments with point-of-sale hardware and business tools that work out of the box
Not for
Software teams needing deeply programmable payment infrastructure, or sellers wanting the lowest possible per-transaction cost at high volume
