There's a moment every SA business owner has. You've decided you need a website. You Google "how to build a website." Wix appears. It's cheap, cheerful, and promises you can be online by tonight.

Some stop there. They build something, launch it, and six months later wonder why Google doesn't know they exist.

Others resist the temptation, call a designer, pay proper money, and get a site that actually works. A year later they're getting calls from customers who found them on page one of Google.

The question — and I get asked this at least once a week on WhatsApp — is: which one are you? Because the honest answer isn't always "go custom." For some businesses, Wix is genuinely fine. For others, it's a slow-motion money drain disguised as savings.

Let's pull it apart. No agency spin. Just the data.

What Wix and a Custom Site Actually Are (The Grandma Version)

Think of your website like your shop. Wix is renting a stall in a mall. The mall handles the electricity, the cleaning, the security — you just show up and decorate. It's cheap, it's fast, and you're open for business quickly. But here's the catch: you don't own the stall. The mall's rules apply. And if the mall changes its policies — or you need a bigger stall — you start again from zero.

A custom-built site is buying your own shop on the high street. The upfront cost is higher. But you own it. You can renovate it exactly how you want. You can connect it to any system you need. And when your business grows, it grows with you.

Both get you open for business. The question is: are you planning to trade from that spot for six months, or six years?

That 74.9% Core Web Vitals figure deserves a pause. Wix has dramatically improved its platform in the last two years. In 2018, only 8% of Wix sites were considered fast. Today, Wix outperforms vanilla WordPress on Google's speed metrics. That's a genuine win for the platform — and it matters, because Google ranks fast sites higher. In practice, however, custom sites hosted locally (or on a South African CDN like Cloudflare or Hetzner) can still cut load times by 300–500ms for SA visitors, because Wix's infrastructure is US-based. On a 4G connection in Pretoria, 500ms is the difference between a visitor who stays and one who bounces.

The Real Cost Breakdown: What You're Actually Paying Over 3 Years

Here's where the "Wix is cheap" argument gets complicated. The monthly subscription looks affordable. The actual total cost — when you factor in transaction fees, forced upgrades, and the revenue you lose while your amateur site sits invisible on Google — tells a very different story.

Look at that brochure site row carefully. At face value, Wix at R11,300 beats a custom site at R10k–24k. On a pure sticker-price comparison, Wix wins for basic sites. But that math only holds if your site brings you zero business — because if a better site brings you even one extra client per month, the entire calculation inverts.

A well-built R12,000 custom site that gains five new R3,000 clients per month pays for itself in under a week. The "cheap" option that costs you those clients because it loads slowly or ranks nowhere? That's not cheap. That's expensive and invisible.

The Wix Hidden Costs Nobody Puts in the Comparison Table

The subscription price is the easy part. Here's what the Wix sales page doesn't mention.

The PayFast Problem

If you're selling anything online in South Africa, you almost certainly need PayFast. It's the dominant local payment gateway — used by most SA banks, integrated with most SA accounting software. Wix doesn't support PayFast natively. Their workaround is "manual payment instructions" — which is the digital equivalent of asking a customer to write you a cheque and mail it. Conversion rates on manual payment flows are dramatically lower than one-click gateway integrations. A custom WordPress/WooCommerce site integrates PayFast, Ozow, Yoco, SnapScan, and Zapper without friction.

The Transaction Fee Drain

Wix charges 2.9% on every sale made through its store. Plus R270 per chargeback. For a business doing R50,000 per month in e-commerce revenue, that's R1,450 every month — R17,400 per year — going straight to Wix before you've paid a cent in tax or profit. That's R17,400 you could have kept with a properly integrated custom store.

The Storage Squeeze

The Wix Light plan gives you 2GB of storage. A mid-sized product catalogue with decent photography will hit that ceiling fast. When you hit it, the site pauses until you upgrade. That forced upgrade jumps you from R300/month to R520/month or higher — and you have no choice, because your site is down. That's not a feature. That's a trap.

The Lock-In

If you decide to leave Wix, you can export your text and images. You cannot export your site design. You cannot migrate your store. You cannot take your page layouts, your template customisations, or any of the design work you or your designer did. You rebuild from scratch — which means paying for a new site on top of whatever you already spent. Agencies call this "migration cost." The real name for it is starting over.

The SEO Reality That Determines Whether Anyone Finds You at All

This is where the conversation gets serious for most SA business owners. Because it doesn't matter how beautiful your website is if nobody can find it.

Wix has improved its SEO tools significantly. It now supports metadata, sitemaps, structured data, and has an SEO wizard that walks you through basics. For a simple local site targeting low-competition terms, Wix's SEO is adequate. But adequate isn't the same as competitive.

Custom sites — particularly WordPress with Yoast or RankMath — give you full control over URL structure, canonical tags, schema markup, heading hierarchies, image alt text, and technical SEO elements that Wix constrains or hides entirely. For competitive local keywords like "plumber Centurion" or "salon Pretoria North," those technical advantages compound over time.

The Gauteng company we mentioned at the start? They moved from Wix to WordPress and saw 18% better local rankings alongside those faster load times. That's not a coincidence. That's the compounding effect of full technical SEO control over 12 months.

The Honest Decision Framework: Wix vs Custom, Built for SA Business Owners

The Quick Checklist: Which Platform Does Your Business Actually Need?

The Part Nobody Talks About: Your Website Is the Foundation, Not the Goal

Here's something most platform comparisons miss. Whether you choose Wix or a custom site, the platform debate is ultimately secondary to a more important question: does your website convert visitors into customers?

A beautifully built custom WordPress site that loads fast, ranks well on Google, and has every feature you need — will still fail if the design is confusing, the copy is weak, or there's no clear call to action. Conversely, a well-designed Wix site for a portfolio photographer might convert better than an amateur WordPress build that nobody can navigate.

Platform matters. But strategy matters more.

The reason that Gauteng company saw 22% more conversions after switching platforms wasn't just because they left Wix. It's because when they rebuilt their site, they rebuilt it with intention — faster pages, clearer messaging, a mobile-first layout, and proper local SEO. Any of those improvements individually would have helped. Together, they compounded into 22% more business from the same traffic.

That's what a properly built website does. It's not an expense. It's a multiplier on everything else you're already spending on marketing.
