Best Ecommerce Platform for Small Business: 6 Tools Compared

An ecommerce platform is the software that turns a product catalog into a working online store: pages you can design, a checkout that takes payment, and a back office that holds your orders and inventory. For a small business it usually replaces a stalled Instagram page and a spreadsheet of orders nobody has updated since launch.

The cost of not choosing deliberately is measurable. A store doing $3,000 a month in sales pays roughly $105 a month in card processing alone at standard rates, before hosting, subscriptions, or plugins. Pick the wrong platform and you carry a 2% platform commission on every order for years, or you hit a product cap in month three and rebuild the catalog from scratch.

Shopify wins for sellers who need a broad app ecosystem on day one. WooCommerce wins for businesses already running WordPress that want no platform commission. Squarespace Core wins for design-led stores selling physical goods. BigCommerce fits B2B catalogs past Shopify’s variant cap. Ecwid fits catalogs under 100 products. Wix fits a store built alongside a broader marketing site.

Key facts: Shopify Basic costs $29/month on annual billing and charges 2.9% + 30¢ in card rates. WooCommerce core is free with no platform fee, but hosting runs $25 to $350 a month. Squarespace Basic charges a 2% commerce fee that Core removes. BigCommerce Core is $29/month and auto-upgrades past $30K in trailing annual sales.

The honest traps: what ecommerce platform pricing pages leave out

The subscription tier is not the differentiator. Shopify Basic, Squarespace Core, BigCommerce Core, Wix Core and Ecwid Venture all land between $29 and $35 a month on annual billing. At that point the tier tells you almost nothing. What separates them is the fee sitting on top of card processing.

The third-party gateway penalty is invisible until you leave the native processor. Shopify adds 2% per transaction when you pay through anything other than Shopify Payments. BigCommerce applies a 1.0% Open Payment Provider Fee on Core, dropping to 0.6% on Scale, but charges nothing on orders running through its 20-plus embedded providers. Same product, different checkout configuration, different margin.

Squarespace Basic is a trap for anyone actually selling. At $19 a month it looks like the cheap entry, but it adds a 2% fee on physical goods and 7% on digital content and memberships.

Core costs $10 more per month and removes the store fee entirely. The crossover is brutal: at $1,000 a month in sales, Core is already $10 cheaper. At $10,000 it is $190 cheaper.

BigCommerce counts GMV as gross order value minus 10%. That reduction applies to both your plan threshold and the open-provider fee calculation, so the sales figure on your dashboard and the sales figure BigCommerce bills you on will not match. Core also auto-upgrades to Growth past $30K in trailing 12-month GMV, which for a seasonal business can happen in a single good quarter.

WooCommerce free is not zero. The core plugin carries no subscription and takes no revenue share, which is genuinely rare. But someone has to host it, and WooCommerce’s own pricing page puts hosting at $25 to $350 a month, with extensions running $29 to $299 a year each. Budget for the building, not just the platform.

Ecwid’s $5 Starter plan caps you at 10 products. It also forces a subdomain rather than your own domain. A catalog with 25 items has already outgrown it, which means the real decision is Starter at $5 or Venture at $35, not whether to start cheap.

Shopify for sellers who need the app ecosystem on day one

Shopify is the default answer for a reason: the app store. When a store needs a subscription tool, a review widget, or a shipping integration, the connector usually already exists and installs in a click. For a business without an in-house developer, that is the difference between a working integration and a quarter of scoping.

Basic costs $29/month on annual billing, $39 on monthly, with card rates from 2.9% + 30¢ on standard cards, 3.5% + 30¢ on premium cards, and an added 1% for international orders. Shopify Payments keeps you at the native rate. Routing through Stripe or PayPal instead costs an extra 2% per transaction.

The traps are concrete. Basic caps a product at 2,048 variants across three option values, includes three markets, and covers only two team accounts. POS Pro, the in-store tier, runs $89 per location on top. None of that blocks a small seller, but each one becomes a decision the month volume forces it.

Skip Shopify if your catalog is deep, your variant count is climbing, or you want zero platform margin. Choose it if integrations are your bottleneck, because no other platform at this price has an equivalent catalog of ready connectors.

WooCommerce when you already run WordPress or have someone maintaining code

WooCommerce is the only option here with no platform commission at all, and the comparison that matters is against the extra 2% Shopify charges for third-party gateways. On $3,000 a month that gap is $60 a month. On $10,000 it is $200, and it recurs every month you operate.

The cost is structure, not fees. Core is free with no monthly subscription and no revenue share. Hosting runs $25 to $350 a month depending on traffic. Extensions run $29 to $299 a year each. Payments come through WooPayments at roughly 2.50% to 2.90% + 30¢, or any processor you prefer at the standard rate.

What you gain is control. Unlimited product variants, unlimited markets, no platform throttle on GMV, and subscriptions handled natively by WooCommerce Subscriptions with no extra platform fee. For a business already publishing on WordPress, this is the same content team, the same host, one more plugin.

Skip WooCommerce if nobody on your side can maintain a WordPress site. Updates, security patches, and a plugin conflict at 9pm are real operational costs even when they do not appear on an invoice.

Squarespace Core for design-led sellers selling physical goods

Squarespace Core is the one Squarespace plan to look at, and the reason is arithmetic rather than aesthetics. Core costs $29/month annual, $39 monthly, charges card rates of 2.9% + 30¢, and applies zero commerce transaction fee on product sales.

Basic is the trap. At $19/month annual it carries a 2% commerce fee on products and 7% on digital content and memberships. Run the numbers: on $3,000 a month of physical goods, Basic totals $184 and Core totals $134. For $10 more a month, Core removes the fee entirely.

The design quality is the actual argument. Squarespace is the strongest of the hosted options for a brand-led catalog where the product photography carries the sale and nobody wants to argue with a template. Core also unlocks unlimited contributors, professional email, and sales funnel analytics.

Skip Squarespace if you sell courses or memberships rather than goods. Core still charges 5% on digital content, and Plus at $49/month drops that to 1% before dropping card rates to 2.7% + 30¢. If digital products are the business, GoHighLevel-style ecosystems or a dedicated billing tool usually serve you better.

BigCommerce for B2B catalogs that outgrow variant limits

BigCommerce Core sits at $29/month annual, $39 monthly, with card rates of 2.89% + 29¢. That processing rate is the lowest in this comparison, and on $10,000 a month the saving over 2.9% + 30¢ is roughly $12 a month against a $50 AOV.

The real differentiator is B2B. Buyer portals, SKU-level pricing for customer groups, price lists for negotiated accounts, and advanced product filtering are native rather than bolted on. For a wholesaler selling 400 line items to trade accounts, that is the reason to be here.

Understand the open-provider fee before choosing a processor. BigCommerce charges 1.0% on Core, 0.6% on Growth and Scale, and 0.0% under Performance contract terms, but only on orders running through payment providers outside its embedded list. More than 20 processors qualify as embedded, so many stores never pay it.

Skip BigCommerce if your catalog is simple and your buyers are consumers. A 0.6% to 1.0% surcharge on the wrong processor is pure cost, and Core’s $30K trailing GMV ceiling will push a seasonal seller into a higher tier sooner than expected.

Wix for a store built alongside a broader marketing site

Wix makes sense when the store is one section of a wider marketing presence: a booking page, a course, an events calendar, and a small catalog selling physical products or printed material. Core is $29.77/month on annual billing including tax, with a free domain for the first year.

The platform cost is competitive. Core carries no commerce transaction fee, and card processing runs at the standard 2.9% + 30¢. Storage is 50 GB and collaborator seats cap at 5, which fits a small team editing its own catalog.

Where Wix differentiates is the surrounding toolkit rather than the checkout. Bookings, scheduling, and email marketing sit in the same subscription, which removes a separate tool from a business that already uses them. The free plan needs no credit card, so testing a catalog before committing costs nothing.

Skip Wix if ecommerce is the whole business. The strength is breadth across a marketing site, and a dedicated commerce platform will out-perform it once orders become the priority rather than an add-on.

Ecwid for small catalogs on the tightest budget

Ecwid wins one narrow contest cleanly: the cheapest credible way to sell a handful of products. Starter is $5/month for up to 10 products, with 70-plus templates and email support. It uses a company.site subdomain, which is the compromise.

Venture at $35/month is the plan most small sellers will land on. It raises the cap to 100 products plus e-goods, adds Instagram and Facebook selling, a mobile store management app, live chat support, automated tax, a custom checkout and a custom domain.

Business at $65/month is for teams. It lifts the catalog to 2,500 products, adds marketplace and subscription selling, two staff accounts, phone support, abandoned cart recovery, and wholesale pricing groups.

Skip Ecwid if you sell more than 100 products or need B2B pricing. Those are the exact boundaries of Venture and Business, and the jump from $35 to $65 is steep for a small seller who simply has a long catalog.

Read the table as a range, not a ranking. The top six rows sit within $4 of each other at every volume, so the subscription price is not where the decision gets made. The bottom two rows are the ones that cost real money over a year.

Final decision path: how to pick without a costly migration

Start from the constraint that cannot be negotiated, which is usually who maintains the site. If the answer is a designer or an owner who is not technical, Wix Core and Squarespace Core are the realistic shortlist. If an agency or a developer handles it, WooCommerce is worth serious consideration for the zero platform fee.

Next, decide what the store actually sells. Physical goods with a broad catalog and integration needs point to Shopify Basic at $29 a month. Trade accounts and SKU-level B2B pricing point to BigCommerce Core. Catalogs under 100 products with no technical help point to Ecwid Venture at $35.

Then do the one calculation most buyers skip. Run your expected monthly sales at four volumes, $1,000, $3,000, $5,000 and $10,000, and add the platform fee to the card rate rather than comparing subscription prices alone. At $3,000 a month the spread between the cheapest and the most expensive realistic setup is about $50, and it grows from there.

Finally, check the plan ceiling before you commit. Shopify caps variants at 2,048 per product, Ecwid Venture caps at 100 products, and BigCommerce Core auto-upgrades past $30K in trailing annual GMV. A platform you will outgrow in eight months costs more than a slightly pricier one that fits.

Whichever path you pick, the payment rate deserves its own review, since it applies to every order and is usually the largest line on the invoice. We break down the processors themselves in our payment processor fee comparison, and sellers moving to recurring billing should read our subscription billing software guide before launch.
