Retail POS Square is the most transparently priced POS we track — plans, rates and hardware are published on official pages, and all figures below were pulled from them (plus Square's hardware shop) when we checked on 2026-08-09. The catch isn't hidden prices; it's which tier your workflows live on. Since the October 6, 2025 restructuring, inventory tracking, purchase orders and barcode labels all require the $49 Plus plan. Here's the full picture, including what a real first year costs at two volumes.
Square POS Plans at a Glance
| Plan | Price (per location) | What you get |
|---|---|---|
| Free | $0/mo | Square POS + Square Online store, online ordering, invoicing, Square Banking, basic item library. No inventory tracking, POs or barcode labels. |
| Plus | $49/mo | All 7 POS modes, advanced inventory (tracking, POs, labels, counts), loyalty, marketing tools, staff management, lower in-person rate. |
| Premium | $149/mo | Nearly all Square software: PO import, transfer orders, advanced reporting, 24/7 phone support, lowest rate, 0% gift-card load fee. |
Notes from the official pricing page: the monthly fee for Plus and Premium applies per location; both paid plans carry a 30-day free trial and you can cancel or switch anytime (month-to-month — no long-term contracts is how Square presents it). Square also has custom/enterprise-style pricing for businesses processing $250K+/year in card sales (reported by third parties, not shown on the public pricing page), and legacy “Square for Retail” tiers (Plus at $89/mo) still appear for some existing merchants — new US sign-ups get the three unified plans above.
Feature Gates: What Each Tier Unlocks
| Retail capability | Free | Plus ($49) | Premium ($149) |
|---|---|---|---|
| Item library, auto item images | ✔ | ✔ | ✔ |
| Low-stock alerts | ✔ | ✔ | ✔ |
| Inventory tracking (stock on hand) | — | ✔ | ✔ |
| Barcode label printing | — | ✔ | ✔ |
| Labels printed from received POs | — | — | ✔ |
| Vendor & purchase-order management | — | ✔ | ✔ |
| Import purchase orders | — | — | ✔ |
| Stock counts / counting tool | — | ✔ | ✔ |
| Cross-location transfer orders | — | — | ✔ |
| Product bundles, unit costs, inventory history | — | ✔ | ✔ |
| Inventory reports (aging, COGS, sell-through) | — | ✔ | ✔ |
| Vendor sales report / advanced reporting | — | — | ✔ |
Rule of thumb: if you need to know what's on your shelves, you're on Plus. If stores move stock between each other or you import vendor POs, you're on Premium. The Free plan is a payment + basic-storefront product, not an inventory product.
Payment Processing Fees
Square's own processing is mandatory — you cannot bring another processor — and rates improve slightly by tier (US, from the official pricing page):
| Transaction type | Free | Plus | Premium |
|---|---|---|---|
| In-person (tap/dip/swipe) | 2.6% + 15¢ | 2.5% + 15¢ | 2.4% + 15¢ |
| Keyed-in / card on file | 3.5% + 15¢ | 3.5% + 15¢ | 3.5% + 15¢ |
| Online (incl. invoices) | 3.3% + 30¢ | 2.9% + 30¢ | 2.9% + 30¢ |
| Online via API | 2.9% + 30¢ | 2.9% + 30¢ | 2.9% + 30¢ |
| ACH bank transfer (invoice) | 1%, $1 min | 1%, $1 min, $10 cap | 1%, $1 min, $10 cap |
| Afterpay (BNPL) | 6% + 30¢ | 6% + 30¢ | 6% + 30¢ |
| EBT (SNAP) | 1.8% + 5¢ | 1.8% + 5¢ | 1.8% + 5¢ |
| Cash or check | Free | Free | Free |
Two extra fee rows worth knowing: gift-card loads cost 2.5% on Free/Plus but 0% on Premium, and international card transactions add 1.5% on all plans. EBT processing fees are waived during a beta running through fall 2026. Note that the October 2025 revamp raised the in-person fixed fee from 10¢ to 15¢ per transaction — a real increase for small-ticket retailers.
Hardware Costs
| Device | One-time price | Financing option |
|---|---|---|
| Square Register (2-screen countertop) | $899 | $44/mo × 24 |
| Square Handheld | $399 | $37/mo × 12 |
| Square Terminal (all-in-one w/ printer) | $299 | $27/mo × 12 |
| Square Stand (iPad POS stand) | $149 | $14/mo × 12 |
| Square Kiosk | $149 | $14/mo × 12 |
| Reader: contactless + chip (2nd gen) | $59 | — |
| Reader: magstripe (USB-C) | $10 | — |
| mPoP printer + cash drawer | $549 | — |
The POS apps themselves run on your own iPhone, iPad or Android device — Tap to Pay on a phone needs no hardware at all — so the minimum viable register is $10–59. Financing is offered through Block (purchases $49–$10,000, 15% APR cited on the hardware page, not available in AL, DE, MO, MS, NH or TN); at 15% APR, paying cash is usually the better deal. Barcode scanner pricing wasn't verifiable from official pages (a made-for-Square Socket Mobile scanner has been cited around $199 by press coverage — treat as an estimate).
First-Year Total Cost: Two Worked Examples
Example 1 — Boutique doing ~$10,000/month (~400 transactions, $25 average)
| Cost line | Square Free | Square Plus |
|---|---|---|
| Software | $0/mo | $49/mo ($588/yr) |
| Processing /mo | ~$320 (2.6% + 15¢ × 400) | ~$310 (2.5% + 15¢ × 400) |
| Processing /yr | ~$3,840 | ~$3,720 |
| Hardware (contactless + chip reader) | $59 one-time | $59 one-time |
| Year-one total | ~$3,899 | ~$4,367 |
At this volume the rate difference between Free and Plus saves only ~$10/month — far less than the $49 fee. You upgrade to Plus for the inventory tools, never for the rate.
Example 2 — Busier store doing ~$30,000/month (~1,500 transactions, $20 average)
| Cost line | Free | Plus | Premium |
|---|---|---|---|
| Software /yr | $0 | $588 | $1,788 |
| Processing /mo | ~$1,005 (2.6% + 15¢ × 1,500) | ~$975 (2.5% + 15¢ × 1,500) | ~$945 (2.4% + 15¢ × 1,500) |
| Processing /yr | ~$12,060 | ~$11,700 | ~$11,340 |
| Year-one total | ~$12,060 | ~$12,288 | ~$13,128 |
Assumptions: all sales card-present at each tier's published in-person rate, 15¢ fixed fee identical across tiers, no paid apps, no payroll, hardware excluded from Example 2. Your ticket size and channel mix will shift these — get your effective rate in writing.
The counterintuitive result: at $30k/month, Free remains the cheapest tier in pure cost because the per-transaction 15¢ is identical everywhere and the percentage savings (0.1–0.2%) don't cover the subscription. Break-even math: Plus pays for itself on rates only above ~$49k/month in card volume, Premium only above ~$74.5k/month. Below that, you pay for tiers to unlock features. And for context: at $30k/month, processing alone (~$12k/yr) dwarfs any software decision on this page.
Hidden and Extra Costs
- Keyed-in sales cost 3.5% + 15¢ — a full point above in-person rates. If much of your business is phone/mail/card-on-file, model that mix, not the headline rate.
- Gift-card loads are 2.5% on Free and Plus (0% only on Premium), and international cards add 1.5%.
- Afterpay (buy-now-pay-later) is 6% + 30¢ — price it as a marketing cost, not a payment cost.
- Add-on subscriptions stack. Square Payroll runs roughly $35/mo + $6/person for full service (third-party figure), and deeper inventory via MarketMan is listed at $99/mo per location on paid plans.
- Processor lock-in. Mandatory Square processing means no interchange negotiation ever — the long-term cost most buyers overlook.
- Per-location billing. Plus/Premium fees multiply by store count; a 3-store Premium chain pays $447/mo in software alone.
How to Pay Less
- Stay on Free until a gate actually blocks you. No stock tracking, POs or labels needed? $0/month is the correct price. Upgrade to Plus ($49) the day inventory workflow matters, not before.
- Use the 30-day trial. Both paid plans offer one, and you can cancel or switch anytime — test your real catalog inside the trial window.
- Don't upgrade for the rate. Below ~$49k/month (Plus) or ~$74.5k/month (Premium), the subscription costs more than the rate saves. Upgrade for features only.
- Buy the right hardware. A $299 Terminal covers most single-lane stores; the $899 Register is for dual-screen counters. Start with a $59 reader if you already own a tablet.
- Compare your ticket size against Shopify. If your average ticket is large and transaction count low, Shopify Basic's flat subscription can undercut Square's per-transaction math — see our Shopify POS pricing guide for the side-by-side.
FAQ
Is Square POS really free? What's the catch?
The Free plan is genuinely $0/month — the catch is capability, not price: no inventory tracking, purchase orders or barcode labels (those need the $49 Plus plan), Square processing is mandatory at 2.6% + 15¢ in person, and phone support ends after your first 90 days.
What's the difference between Plus and Premium?
Plus ($49/location) adds the retail inventory kit — tracking, purchase orders, barcode labels, stock counts, bundles, inventory reports — plus loyalty and staff management. Premium ($149/location) adds PO import, cross-location transfer orders, label printing from POs, advanced reporting, 24/7 phone support, the lowest rate (2.4% + 15¢) and 0% gift-card loads.
Can I use my own payment processor with Square?
No. Square doesn't support third-party payment processors — Square processing is required, which is why the flat-rate math above is the only math. That also means you can't negotiate interchange later.
Should I finance Square hardware?
Usually not. Financing runs through Block at a 15% APR cited on the hardware page (and isn't available in six states). A $299 Terminal paid cash beats $27/mo × 12 = $324; pay upfront if you can.
I've seen “Square for Retail Plus $89/mo” — which price is right?
Both, for different merchants. Before October 6, 2025, Square for Retail sold a $89 Plus tier; the revamp replaced 18 subscriptions with the unified Free/$49/$149 plans for new US sellers, while some legacy merchants still see old pricing. If you're signing up today, the table above is what applies.
