Squarespace or Wix — which is better for a small business?

The short answer
Squarespace if you want it to look good without design work, because its constraints make bad outcomes harder. Wix if you want to move things freely and need a wider range of add-ons. Both are competent; neither lets you take your design elsewhere. The decision that matters more than either is whether you can edit your own content and what you keep if you leave.

The honest summary
These two are more alike than different, and either will produce a perfectly good small business website. The differences are real but narrower than the comparison articles suggest.
Squarespace is the constrained one. Fewer templates, tighter rules about what you can move, and consequently harder to make ugly. Good typography by default. If you want it to look considered without hiring anyone, this is the safer choice.
Wix is the flexible one. Drag things where you like, a much larger template library, and a bigger app market. More freedom to get exactly what you want — and more freedom to produce something misaligned and slow.
The rule of thumb: Squarespace protects you from yourself; Wix trusts you. Which is better depends entirely on whether that protection feels like safety or like a cage.
Where each genuinely wins
Squarespace is better at: looking good with no effort, typography, consistency across pages, and getting content out if you ever leave — most content can be exported in a format other platforms understand.
Wix is better at: layout freedom, the range of available add-ons, and having a free tier to start on.
Both are similar on: hosting, security, updates, ease of learning, and quality of support. Neither requires technical knowledge.
What neither lets you do
Take your design with you.
Wix is explicit in its own documentation that a site cannot be exported or hosted elsewhere — the architecture depends on Wix's own services. Squarespace exports content more generously but not the site itself.
So with both, leaving means rebuilding. Your content comes; the design stays. This is not a scandal, it is what a hosted platform is — but it should be a decision you make knowingly rather than discover in year three.
The question that matters more than either
What does it cost you to change something?
On both of these platforms the answer is nothing, because you do it yourself. That is genuinely their biggest advantage, and it is the reason a builder often beats a custom site that nobody can edit.
Hold on to that criterion when comparing anything else. A cheaper option you cannot update is more expensive by the second year, once twenty small changes a year have gone through somebody else's inbox.
When neither is right
You genuinely ship products at volume. A dedicated commerce platform will do that better.
Your design is part of what you sell. A restaurant with a considered room, a studio, a brand-led business. Both of these mean a template, and a template means resembling everyone else who chose it.
You want a site built and run for you. Both of these are do-it-yourself tools. If you do not want to become the person who maintains a website, a managed option is a different and legitimate answer — that is where Helm sits, and it is worth saying plainly rather than pretending this comparison has no author.
How to actually decide
Build the same page on both. Both have free trials.
Take your real content — your actual prices, your actual photographs, your actual opening hours — and build your homepage twice. An afternoon.
You will discover more in that afternoon than in any comparison table, including this one. And whichever one made you less irritated is, genuinely, the right answer for you.
