Free Ecommerce Website Builder: Which One Takes a Real Order?

Posted Sep 4, 2026✓ Re-audited Sep 4, 2026

One free ecommerce website builder takes a real order at a real checkout for $0 a month, and it is Square Online's free plan. Everything else marketed as free is either a trial with a date attached, a plan that cannot accept a payment at all, or software that costs nothing to license and then requires hosting you pay for. The distinction matters because free is a statement about the plan fee only, and the plan fee is one of three lines on the invoice. The other two — the processing rate and the platform's own cut — never go to zero. This audit prices what each free route charges once money actually moves.

Free to build, metered to sell

Start with the plans that call themselves cheap and then decline to take a payment. Wix Light at $17 a month cannot accept online payments at all — the Wix commerce ledger starts at Core, $29 on annual billing. Shopify Starter costs $5 a month and sells only through links and social channels rather than a full storefront, and it processes at 5% + $0.30, which is 2.1 points above Basic. That premium costs $21 per $1,000 of sales against the $24 of plan fee it saves, so Starter stops being the cheaper Shopify at roughly $1,140 a month — a line sellers routinely blow through while still calling it the budget option.

Then the ones that used to be free and are not. Ecwid discontinued its free plan on March 2, 2026; the entry point is now Starter at $5 a month for up to 10 products. And then the free software: WooCommerce carries a $0 license, which is genuinely free and also not the bill. Hosting for a small store runs $4 to $30 a month — call it $15 for a competent managed tier — a domain runs $12 to $20 a year, and the maintenance is yours: core updates, plugin updates, security patches, backups, and the debugging session when an update breaks checkout on a Friday evening. Three hours a month at $50 an hour is $150 that no invoice records.

The $50 order, priced on every free route

Here is the same order — $50, one US standard card — put through every route that advertises itself as free or near-free. The column that matters is the last one, because it names the thing the free plan is actually charging you for.

Read the second and fourth columns together. The route with the lowest plan fee does not have the lowest cost per sale, and the route with the lowest cost per sale is not free at all. That inversion is the entire subject of this page, and our fee table runs the same exercise across all eight builders we track.

The one free plan that takes a real order

Square Online's free plan is not a demo. It carries point of sale, a website, online ordering, invoicing, and Square Banking, nothing in that list is metered, and there is no platform commission on any Square plan — the company's margin lives entirely in the processing rate. Which is why the rate is the thing that moved: on January 13, 2026, online processing went from 2.9% to 3.3% + $0.30 on Free, quietly the largest single fee increase in our table that year. The tier stayed free; the meter did not.

Run the house example and the case makes itself at modest volume. At $2,000 a month across 40 orders, a free Square Online store books $66.00 of rate plus $12.00 of fixed fees for $78.00 — an effective 3.9%, and $21.00 under the $99.00 that Shopify Basic, Wix Core, and Squarespace Core each charge on the identical month. Drop to $500 a month across 10 orders and the gap becomes structural rather than marginal: Square costs $19.50, still 3.9%, while a $29 plan at 2.9% + $0.30 costs $46.50, an effective 9.3%. With no plan fee to amortize, Square's effective rate is flat at every volume; plan-fee builders start brutal and improve. At hobby scale, free is not slightly cheaper, it is less than half the cost.

The crossover against Shopify Basic sits at $7,250 a month in online sales, where both bills come to $239.25 to the cent, and it moves to $9,750 if you pay Shopify monthly at $39 instead of annually at $29. We worked that matchup in full. Two checkpoints on the way: at $4,000 across 80 orders, Square is still $13.00 ahead; at $8,000 across 160 orders, Basic wins by three dollars. If you intend to cross that line, the Shopify Basic plan is where the ledger points, and its 3-day trial followed by $1 a month for three months makes the test nearly costless.

When free stops being free

The ceiling arrives before the crossover

We cap the free recommendation nearer $1,500 a month than $7,250, and the reason is not in the fee column. At $1,500 the 0.4-point premium already costs $6.00 a month and grows with every sale, while the non-fee ceilings — the subdomain, the branding footer, the limited design control — start costing conversions that no fee table records. Fees you can calculate to the cent. Conversions lost to a builder's ceiling you cannot.

Free plans and digital goods do not mix

If you sell downloads or memberships, check the platform fee before the plan fee. Squarespace charges 7% on digital content and memberships at Basic, 5% at Core, 1% at Plus, and 0% at Advanced — so on $2,000 a month of digital sales, the cheap seat costs $229.00 while Squarespace's Plus plan costs $135.00. The cheapest plan is the most expensive month, and it is not close.

Free is a starting balance, not a strategy

The practical sequence: start where the plan fee is zero, take real orders, and let your own numbers name the switching month rather than a review. Run your volume and order count through the fees calculator monthly, and when you do move, move deliberately — our ranked ledger of store builders and the weekend launch plan both assume a real test order before anything is called live.

Disputing the entries: free-plan questions

Is there a genuinely free ecommerce website builder?
Square Online's free plan is the one on our ledger that costs $0 a month and still runs a working checkout, with no plan fee and no platform commission. You pay 3.3% + $0.30 on every online card, which is the highest online rate in our table, and the site publishes to a square.site subdomain with a small Square branding footer.
What does a free store cost per sale?
On Square Online Free, a $50 order costs $1.95 — 3.3% is $1.65, plus the $0.30 fixed fee. That is an effective 3.9% at a $50 average order size, and because there is no plan fee to spread, the effective rate stays 3.9% whether you sell $500 or $5,000 in a month.
When should I stop using a free plan?
On fees alone, at $7,250 a month in online sales, where Square Free and Shopify Basic both bill $239.25. In practice we cap the recommendation nearer $1,500, because above that the subdomain, the branding footer, and the design limits start costing conversions that no fee table measures, while the 0.4-point rate premium keeps growing.
Is WooCommerce a free ecommerce builder?
The software licence is $0, which is not the same as free. Hosting for a small store runs $4 to $30 a month, a domain is $12 to $20 a year, and updates, security patches, backups, and plugin-conflict debugging are yours to do. Priced at three hours a month, that maintenance costs more than the plan fee it saves.
Can I use a custom domain on a free store plan?
On Square Online, connecting a custom domain appears to require a paid plan at the time of checking, and Square sells domains at around $19.95 a year. Confirm the current terms inside your own account before committing, because the domain question decides whether the free tier reads as a brand or as a stall.
