Squarespace vs. Custom Website: What NZ Businesses Actually Need to Know

If you’re a small business owner in New Zealand weighing up your website options, you’ve almost certainly looked at Squarespace. It’s everywhere. The ads are slick. The templates look gorgeous in the demo. And $33/month for a “business” plan sounds like a bargain compared to paying a developer.

We’re not here to tell you Squarespace is terrible. For some use cases — a quick personal portfolio, a weekend hobby blog — it does the job. But for a business that depends on its web presence to generate leads, sell products, or build credibility, the calculation changes dramatically.

Here’s the honest breakdown.

The True Cost of “Cheap”

Squarespace’s Business plan costs NZ$53/month (about NZ$636/year). The Basic Commerce plan — which you’ll need if you’re selling anything — runs NZ$46/month. Let’s use the Business plan as our baseline.

Over three years, you’ll spend approximately NZ$1,900 just on the subscription. Over five years, that’s NZ$3,180. And you still don’t own anything. Cancel your subscription and your site disappears. Every dollar you’ve paid is rent, not equity.

A custom-built website from a developer like Quick Site is a one-time investment. You own the code. You choose your hosting (which typically costs $5–20/month for a static site, compared to Squarespace’s locked-in pricing). After the initial build, your ongoing costs are a fraction of what you’d pay Squarespace — and you have complete control.

Performance: Where Templates Fall Apart

This is where the difference becomes stark. We recently benchmarked a Squarespace site against a custom Astro build for a Christchurch-based café client. Both had similar content — a homepage, menu, about page, contact page.

Metric	Squarespace	Custom Build
Page Weight	3.2 MB	287 KB
Requests	47	8
LCP (Load Time)	4.1 seconds	0.9 seconds
Performance Score	52/100	99/100

The Squarespace site loaded 4.5 times more data and made nearly six times as many network requests. Every one of those extra requests is a potential point of failure on a slow mobile connection — which is how most of your customers are browsing.

This isn’t a cherry-picked example. It’s structural. Squarespace loads its own platform JavaScript, analytics, font rendering engine, form handlers, and commerce framework on every page — regardless of whether you use those features. A custom build loads exactly what you need and nothing else.

SEO: The Hidden Penalty

Google doesn’t just use Core Web Vitals as a minor tiebreaker anymore. Performance is a direct ranking factor. A site scoring 52/100 on PageSpeed Insights is at a measurable disadvantage against a competitor scoring 99/100 — all other things being equal.

Beyond raw performance, Squarespace has structural SEO limitations:

• Limited control over HTML structure — You can’t optimise heading hierarchy, add structured data (JSON-LD) without workarounds, or control how the page renders for crawlers.
• Bloated code output — Squarespace generates verbose, nested HTML that search engines need to parse through to find your actual content.
• URL structure constraints — You get some control, but not full control. Custom builds let you engineer URLs precisely for your target keywords.
• No server-side rendering control — You can’t implement advanced techniques like prerendering, edge caching, or CDN-level optimisation.

For a local business trying to rank for “plumber Christchurch” or “café Sumner,” these differences matter. The first page of Google has ten spots. Your competitors are fighting for them too.

Design: “Custom” Isn’t What You Think It Means

Squarespace markets its templates as “customisable.” And they are — within strict limits. You can change colours, swap fonts, rearrange some sections, and upload your own images. But the underlying structure is shared with thousands of other sites using the same template.

A genuinely custom website has no structural constraints. Every element serves your specific business goals. The layout, the interaction design, the conversion flow — all of it is engineered for your audience, your services, and your market. The difference is immediately visible to visitors, even if they can’t articulate why. One site feels generic. The other feels intentional.

When Squarespace Makes Sense

To be fair, there are scenarios where a template builder is the right call:

• You need a site up in 24 hours for a one-off event
• Your budget is genuinely under $500 and you’re willing to invest your own time building it
• The site is secondary to your business (a personal project, a hobby)
• You have no plans to optimise for search or generate leads from the site

If none of those apply — if your website is a genuine business tool — the maths favour a custom build every time.

The Quick Site Approach

We build lightweight, modern websites using static-site technology that ships virtually no JavaScript to the browser. Every site is designed from scratch — no templates, no themes, no drag-and-drop builders generating bloated code behind the scenes.

The result is a site that loads instantly, ranks higher, converts better, and costs less over its lifetime than a Squarespace subscription. You own the code outright. You choose where to host it. And if you ever want to move to a different developer, you can — because there’s no vendor lock-in.

Standard builds are delivered in under a week. Not months. Not “we’ll get back to you.” Days.

Make an Informed Decision

If you’re currently on Squarespace (or Wix, or WordPress.com) and wondering whether a custom build is worth it, we offer a free site audit. We’ll benchmark your current site’s performance, identify what’s costing you traffic and conversions, and give you a clear picture of what a purpose-built alternative would look like.

No sales pitch. No pressure. Just data and a recommendation you can trust.
