Square Online for Stores: The Fees-First Audit (2026)

Square Online fees changed twice in nine months, and if you run a store on the platform — or are pricing one — the January 2026 change is the line that matters: the free plan's online card rate rose from 2.9% to 3.3% + $0.30. This is a fees-first audit for store owners, not a product walkthrough. We price the three plans, itemize what free actually includes, and work out the exact sales volumes where 3.3% stops being the cheap answer.

Plan prices and rates were verified in August 2026 against Square's announcements and independent fee trackers; two smaller items could not be pinned to a primary source and are flagged below.

October 2025: eighteen subscriptions become three plans

On October 6, 2025, Square collapsed 18 separate subscriptions into three plans: Square Free at $0 a month, Square Plus at $49, and Square Premium at $149 — each priced per location, a detail multi-site sellers should read twice. The old maze of per-product add-ons is gone; what remains is one clean question of tier. For a fee auditor this was an improvement: fewer lines, fewer surprises, one rate card per plan. The relevant consequence for stores is that there is no longer a cheap middle tier to hide in — you are either on Free with the higher online rate, or paying $49 a month for the lower one, and everything below prices that gap.

January 2026: the rate change that is the spine of this audit

Effective January 13, 2026, online processing moved to 3.3% + $0.30 on the Free plan (from 2.9%) and 2.9% + $0.30 on Plus and Premium (from 2.6%). In person, the card-present rates are 2.6% + $0.15 on Free, 2.5% + $0.15 on Plus, and 2.4% + $0.15 on Premium, with keyed-in transactions at 3.5% + $0.15 across the board.

Note the shape of the spread. On Free, an in-person card costs 2.6% + $0.15 while an online card costs 3.3% + $0.30 — the same dollar earns Square 0.7 points more when it arrives through the website. A seller doing half their volume at the counter therefore runs a blended rate meaningfully below the online headline, which is one reason the free plan suits POS-first businesses better than online-only ones.

There is no platform commission on any plan — Square's margin lives entirely in the processing rate, which is exactly why the rate is the thing that moved. The structure is honest; the honesty simply got 0.4 points more expensive for free-plan sellers.

What free actually includes

The $0 plan is not a demo. It carries POS, a website, online ordering, invoicing, and Square Banking — a genuinely operable business stack with no subscription attached. The site publishes to a yourname.square.site subdomain and carries a small Square branding footer. Nothing in that feature list is metered — the $0 is a real price, not a teaser.

Two caveats we could not fully verify, flagged accordingly. At the time of checking, connecting a custom domain appears to require a paid plan — before the unification it sat on the old $12-a-month Professional tier, whose features folded into Plus — and Square sells domains at around $19.95 a year. If the free-forever plan with your own domain is the whole strategy, confirm the domain terms inside your account before you commit. Neither caveat changes the fee math; both change whether the free tier reads as a brand or a stall.

The math where free wins

Our house test case is $2,000 a month across 40 orders at a $50 average. On Square Free: 3.3% of $2,000 is $66.00, plus 40 fixed fees at $0.30 is $12.00, and the plan contributes nothing. Total: $78.00 — an effective 3.9% of revenue, and the cheapest row in our comparison table at this volume. The $29-plan builders (Shopify Basic, Wix Core) each book $99.00 on the same month. Free wins by $21.00, every month, for as long as volume stays modest.

The structural point hiding in that arithmetic: with no plan fee, Free's effective rate is flat. At a $50 average order it runs 3.9% whether you sell $500 or $5,000 — the fixed $0.30 adds 0.6 points, the rate adds 3.3, and nothing else exists. Plan-fee builders work the other way: their percentage starts brutal and falls. At $500 a month across 10 orders, Square Free costs $19.50 — still 3.9% — while a $29-plan builder at 2.9% + $0.30 books $46.50, an effective 9.3%. At hobby volume, free is not slightly cheaper; it is less than half the cost.

The crossover: where 3.3% starts to cost you

Now the arithmetic the folklore skips. Free's premium over a 2.9% builder is 0.4 points — $4 per $1,000 of sales. Against a $29-a-month plan at 2.9% + $0.30, the premium overtakes the plan fee only at $7,250 a month in sales. Against WooCommerce on roughly $15-a-month hosting, the crossover lands at $3,750. And against Square's own Plus plan at $49 with the 2.9% rate, Free stays cheaper in pure cash until $12,250 a month online. On fees alone, free survives far longer than most write-ups admit.

Two checkpoints on the road to that crossover, holding the $50 order steady. At $4,000 a month across 80 orders: Free books $132.00 plus $24.00 in fixed fees — $156.00 — while a Shopify Basic setup books $29 plus $116.00 plus $24.00 — $169.00. Free is still $13.00 ahead. At $8,000 across 160 orders: Free reaches $312.00; Basic reaches $309.00. The lines have crossed, by three dollars, almost exactly where the formula said they would.

So why do we cap the recommendation near $1,500 a month? Because the fee ledger is not the whole ledger. At $1,500 the 0.4-point premium already costs $6.00 a month and rises with every sale — a fee that scales, traded against plan fees that do not. Meanwhile the non-fee ceilings — the branding footer, the subdomain question flagged above, the limited design control — start costing conversions no fee table records. Past that mark, our position is: pay a plan fee somewhere, take the 2.9% rate, and get a proper storefront while you are at it. Fees you can calculate to the cent; conversions lost to a builder's ceiling you cannot — and we cap the recommendation where the second risk starts outweighing the first.

POS sync: the real reason to stay

For a seller already running Square at the counter, the calculus changes entirely. The online store activates on the Square account you already have, inventory and orders stay in one system, and in-person sales keep their 2.6% + $0.15 rate on Free. The website becomes, in effect, a free extension of the register — and no dedicated store builder offers that continuity. This is the strongest single entry in Square's credit column, and it applies at any volume. One caution for the counter: keyed-in orders taken over the phone run 3.5% + $0.15 on every plan, the dearest rate on Square's card — worth knowing before call-in orders become a habit.

The balance

The 7.4 reflects a narrow, genuine excellence: under about $1,500 a month — or with a Square register already on the counter — this is the correct fee answer, and $0 of subscription buys a working business. Above that line, the 3.3% rate is the highest in our table and the platform's ceilings begin charging rent in ways no invoice shows. Run your own volume through the fees calculator to find your personal crossover, compare the field in our ranked audit of the best ecommerce website builders, or open a free Square Online store and let the ledger tell you when it is time to move. The right month to switch will show up in your own numbers long before any review could call it for you.
