What is the best platform to start an online store?

Ask ten experts to name the best ecommerce platform and you'll get three different answers — and the data backs them all up.

Shopify is the market leader by any measure. It holds a 23.3% global usage share among store-building platforms, with Magento (8.4%) and WooCommerce (4.9%) trailing far behind, according to platform market data. It also powers over 5.6 million active stores worldwide. But leading the market isn't the same as being right for your store.

The research consistently splits the answer by use case. Per a detailed platform comparison, Shopify wins for anyone building a serious ecommerce business, Squarespace wins for portfolios and light digital-product sales, and Wix wins for beginners who want a flexible all-in-one builder without committing to a commerce-first platform. Ease of use follows the same pattern: Wix is gentlest, Squarespace balances simplicity with professional design, and Shopify demands a moderate technical understanding that pays off at scale.

• Shopify — the default for commerce depth, checkout control, and scale headroom, with 8,000+ apps and 100+ payment processors
• Squarespace — the pick for design polish and digital products, with transaction fees dropping to 0% on its top tier
• Wix — the easiest start for beginners, with 800+ templates and drag-and-drop simplicity
• Budget options — free basic plans from Square or Ecwid can get a first store live for almost nothing

Two other realities should shape your decision. First, the real differentiator isn't sticker price — it's ecommerce depth. As one small-business guide warns, a cheap starter plan can lose its effectiveness as you grow, while a pricier platform may cost less in the long run. Second, your store competes in a marketplace-dominated world: 2025 US market analysis shows Amazon captured 37.6% of retail ecommerce sales, with 87% of shoppers using it during Cyber Weekend. Your platform choice matters less if no one finds your store.

That's why the better question isn't "which platform is best?" but "which platform fits my business model, my technical comfort, and my plans for growth?" A merchant selling digital downloads has different needs than a restaurant taking online orders or a service business booking appointments. For owners who'd rather not learn any platform at all, a done-for-you approach — like the managed builds AI Business Sites provides, with ordering and bookings built into a custom site — trades the DIY learning curve for a system someone else runs.

Match the tool to the job, budget for total cost of ownership, and choose headroom over the lowest monthly fee. That's how you find your "best."

When it comes to launching an online store, the platform you choose can make or break your success. The data is clear: Shopify stands out as the default choice for commerce-first businesses. With a staggering 23.3% global market share and roughly 26–30% of the US market, Shopify powers over 5.6 million active stores worldwide. This is a testament to its reliability and scalability, making it a great fit for most businesses, regardless of their size.

But what makes Shopify the go-to platform for ecommerce? The answer lies in its depth of features tailored for serious online selling. Platforms like Shopify offer more than just a simple storefront; they provide an extensive app ecosystem, robust checkout control, and scalability that can grow with your business. These features are critical for businesses looking to expand beyond basic selling capabilities. According to industry insights, the real differentiator is ecommerce depth—features that go beyond the sticker price to offer a comprehensive selling experience.

For small businesses, cost is often a primary concern. However, it's essential to consider the total cost of ownership, which includes hidden costs like returns handling, transaction fees, and additional integrations. DIY hosted platforms might seem cheap initially, but they can quickly become costly as your business scales. Custom builds, while more expensive upfront, often prove to be more cost-effective in the long run.

If you're a small business owner looking to start an online store, considering platforms like Shopify can provide the scalability and features you need. However, for those who want a done-for-you solution, AI Business Sites offers a compelling alternative. Our platform takes care of everything from website design and development to ongoing content generation and lead management, ensuring that your online presence is not just a brochure but a fully functional business system.

By focusing on ecommerce depth rather than just the sticker price, businesses can ensure they have the tools necessary to succeed in a competitive market. For those who prioritize ease of use and design, platforms like Wix and Squarespace might be more appealing. However, for businesses serious about ecommerce, Shopify remains the evidence-backed default choice. And for those who want an all-in-one solution that takes the hassle out of managing an online store, AI Business Sites provides a comprehensive, managed service that grows with your business.

The monthly subscription fee is the number every store owner compares before launching — and it's often the smallest number on the invoice. The real cost of running an online store lives in the operational layers beneath the platform: returns, payment processing, traffic, and compliance.

Returns are the first shock. Average online return rates run 20–30%, with clothing and footwear at the top of the range, and handling a return costs up to three times the original delivery cost, according to cost research from MerchantSpring. Every returned order also carries an administrative transaction cost of £7–£10 per task — labor that never shows up on a platform invoice.

Payment processing is the second line item that quietly overtakes the subscription. Some processors charge up to 3% per transaction — a store doing $50,000 in monthly revenue can pay $1,500 in processing fees alone, before the platform fee and before a single ad. Shopify's card processing runs about 2.9% plus $0.30 per transaction unless you use Shopify Payments at higher tiers, per this platform comparison.

Then come the costs that have nothing to do with software:

• Traffic acquisition — ads, SEO, and content that actually bring visitors to the store
• Returns handling, damaged items, and late payments that erode margin
• Insurance and tax compliance, which scale with revenue, not platform choice

The same cost analysis notes that a DIY hosted store can launch for under £1,500, while SME e-commerce builds typically run £2,000 to £20,000. The gap between those numbers is mostly operational — and it's where under-budgeted stores bleed out.

This is why total cost of ownership matters more than the starter plan price. Research from Wise warns that a free or low-cost plan can lose its effectiveness as the business grows, and that platforms with higher monthly fees can actually be cheaper in the long run. The cheapest entry point is rarely the cheapest path.

At AI Business Sites, we see this play out constantly with small business owners who launch on the lowest tier, then bolt on apps, payment tools, and marketing subscriptions until they're managing six different bills. The fix is to choose a platform with room to scale — and to budget for the full operational cost from day one, not just the monthly fee.

Every platform we've compared so far assumes you'll do the work: pick a template, learn the dashboard, configure payments, write the pages, and troubleshoot when something breaks. For a business owner already running full days, that's not a tool — it's a second job.

The numbers explain why so many owners stall. DIY hosted platforms are the cheapest launch path, with a budget store costing under £1,500, but SME e-commerce builds generally run £2,000 to £20,000 depending on scale — and hidden costs like returns, ads, and payment fees (some processors charge up to 3%) often exceed the platform fee itself. Meanwhile, the average Shopify store converts only about 1.4–1.8% of visitors, so a store that launches half-finished quietly burns the traffic you pay for.

That's the gap a done-for-you model fills. Instead of handing you software, a managed service builds and runs the whole thing for you. AI Business Sites works this way: a custom website goes live in 7 days with 85+ pages, and online selling is built in when the business needs it — a product store, restaurant ordering, bookable services, or event tickets, all with card payments through your own Stripe account. You never learn the software; you approve what the system proposes and get on with your trade.

The same logic applies to everything around the store:

• Product, service, menu, and ticket catalogs can run side by side on one site — a tour company selling merch and event seats uses one admin, not three tools.
• Customers can order or book through the site, through chat, or by talking to the website's voice agent.
• Content and SEO are handled continuously — 14+ new keyword-targeted pieces publish every month without you writing a word.
• You own the code, content, data, and domain, and money flows straight to your own Stripe account — no middleman holding your revenue.

This matters because of where the market actually is. Amazon captured 37.6% of US retail e-commerce sales in 2025, and independent analysis shows shoppers treat it as the default tab in the browser. A standalone store can't out-spend that — it has to win on being findable, fast, and genuinely easy to buy from, which is exactly what a managed system is built to deliver.

The trade-off is honest: a done-for-you service costs more per month than a DIY template, and it's wrong for owners who enjoy running their own stack. But if the choice is between learning another platform and never launching at all, the shortcut is simply the faster route to revenue. For most busy owners, the best platform is the one someone else builds, runs, and keeps improving — while they run the business.
