A point-of-sale system — the software and hardware that rings up sales, tracks inventory, and processes payments — used to cost thousands of dollars upfront. Today, three serious platforms will let you start for exactly $0 per month in software fees. That’s genuinely useful if you’re opening your first location or replacing a clunky legacy register. But “free” in the POS world almost always means the software is free while the payment processing — the small percentage the system takes every time a customer swipes a card — is how the company actually makes money. This guide names the best free POS options for 2025, shows you exactly where each one starts charging, and tells you the dollar-figure at which paying for a subscription actually saves you money.
If you already know what a processing rate is and you’ve been burned by a contract clause before, you’re in the right place. We’re going to get specific.
The Three Platforms Worth Your Time
Not every “free POS” survives contact with reality. Some are free only on one device, or only for 30 days, or only if you process under $1,000 a month. The three below have real, sustained free tiers used by actual small businesses at scale.
Square: The Default Starting Point
Square’s free plan (reviewed in depth by PCMag) gives you unlimited products, a basic inventory system, digital receipts, and a free card reader for in-person sales. Software cost: $0/month, permanently — not a trial.
The catch is the processing rate. Square charges 2.6% + $0.10 per in-person swipe on the free tier. If you upgrade to Square for Restaurants Plus ($60/month) or Retail Plus ($89/month), that rate drops to 2.5% + $0.10. That’s a 0.1% difference — almost irrelevant at low volume, real money at high volume.
What Square does well for free: It runs on any iPad or the Square Terminal hardware, it has the most polished UI in this tier, and it integrates natively with dozens of tools (payroll, appointments, online ordering) even on the free plan.
The quiet cost: Advanced reporting, team management with permissions, and loyalty programs are all paywalled. You won’t miss them at $0–$5k/month. You will miss them at $15k+/month.
Loyverse: The Underrated Pick for Multi-Location Operators
Merchant Maverick’s review of Loyverse POS rates it one of the most feature-complete free POS systems for independent retailers — a reputation that holds up in practice. The base software is free forever, works on iOS and Android, supports unlimited items, and includes a surprisingly capable customer loyalty program at no charge.
The model here is different from Square. Loyverse is software only — it doesn’t process payments itself. You connect it to a third-party processor (Zettle, SumUp, or others). That means your processing rate depends on who you pick, not on Loyverse’s markup.
The modular add-on trap is where owners get surprised. Loyverse charges separately for:
- Employee management: $5/month per location
- Advanced inventory (purchase orders, supplier tracking): $25/month per location
- Integrations (connecting to accounting or e-commerce tools): $9/month per location
Start adding those up and a “free” Loyverse setup can hit $39–$75/month before you’ve paid your processor a cent. The platform is genuinely free if you only need the register and loyalty functions. Once you need back-office operations, the math changes fast.
eHopper: The Windows-Friendly Option
eHopper’s free “Essential” plan is the least-discussed of the three, and it fills a specific gap: it runs on Windows PCs and Android tablets, which is meaningful if you already own that hardware or run a business type (alterations shop, small pharmacy, tax prep office) where iPads feel out of place.
Fit Small Business’s review of eHopper POS notes the free tier covers one terminal, basic inventory, and receipt printing. Like Loyverse, eHopper doesn’t force you into their payment processor on the Essential plan — but their “OmniChannel” paid plan ($39.99/month) does include a bundled processor with rates starting around 2.69% + $0.09, which is slightly worse than Square’s in-person rate.
The hardware lock warning: eHopper sells their own tablet bundles that come pre-configured with their payment processing. If you buy one of those bundles expecting to swap processors later, read the equipment agreement first.
The Real Cost Comparison (By the Numbers)
At $15,000/month in card sales, here’s what each platform actually costs you:
| Platform | Monthly Software | Processing Fees (est.) | Total Monthly Cost |
|---|---|---|---|
| Square Free | $0 | $390 (2.6%) | $390 |
| Loyverse + SumUp (1.69% in-person) | $0–$39 | $253 | $253–$292 |
| eHopper Essential + Stripe (2.7%) | $0 | $405 | $405 |
| Square Retail Plus | $89 | $375 (2.5%) | $464 |
Processing estimates use flat-rate in-person rates as of early 2026. Interchange-plus pricing (available through some processors at higher volume) can reduce fees further but requires a separate processor agreement.
The Loyverse + SumUp path wins on raw cost at this volume level — but that’s before you add the employee management and inventory add-ons. Add those and Loyverse lands at $330–$370/month total, still cheaper than Square Plus, and with more flexibility on processing.
What Triggers the Upgrade Decision
Here’s the framework that matters. Free POS stops making financial sense when one of three things happens:
1. Your processing volume crosses ~$10,000/month. At that level, the difference between 2.6% (Square free) and 2.5% (Square Plus at $89/month) becomes roughly $10/month in savings — obviously not worth it. But it’s also the level where shopping your processor starts saving real money. Interchange-plus pricing through a standalone processor (Stripe, Helcim, or a direct merchant account) can bring effective rates to 1.8–2.1% for card-present transactions. On $10k/month, that’s $50–$80/month in savings — enough to pay for almost any subscription POS.
2. You need features you’re working around. If you’re exporting Square reports to a spreadsheet to do labor-cost tracking that Square Plus would handle natively, you’re spending time to avoid a $60/month fee. At some point that’s a bad trade.
3. You’re on your second location. Almost every free tier limits you to one register or one location at full functionality. Loyverse’s multi-location support is genuinely good even on free, but the add-on fees stack per location. Square’s free plan technically allows multiple locations but gives you no consolidated reporting across them — which means you lose the main operational benefit of having a platform at all.
Hardware You Can Actually Reuse
This matters more than most buyers realize. When you switch POS systems — and research from NerdWallet’s small-business editorial team into POS switching patterns suggests most operators do so within three years — you want hardware that doesn’t become a paperweight.
For Square: The Square Terminal ($299) is proprietary. The Square Reader ($49) is also Square-only. But Square runs beautifully on a standard iPad, and that iPad is yours forever. Buy the software, own the iPad, and your hardware investment survives a platform switch.
- Apple iPad (9th generation) on Amazon — the most common Square hardware foundation
- Square Reader for contactless and chip on Amazon — the $49 reader you plug into or pair with that iPad
For Loyverse: Because it’s processor-agnostic, almost any Bluetooth card reader works. The Zettle Reader 2 and SumUp Air are both popular pairings.
- SumUp Air Card Reader on Amazon — pairs cleanly with Loyverse, under $50
For eHopper: Any Android tablet with a compatible receipt printer works. Avoid eHopper’s own bundled hardware packages unless you’ve confirmed processor flexibility in writing.
The Verdict: If X, Then Y
If you’re opening your first location and want zero friction: Start with Square Free. The setup is 20 minutes, the UI is the best in class, and you won’t outgrow it until you’re doing $10k+/month. Accept the 2.6% rate as the cost of simplicity.
If you already have a preferred payment processor or you’re in a vertical where SumUp or Zettle is already your processor: Loyverse is the smarter free choice. You keep your existing processing relationship, get a more flexible inventory system, and pay nothing until you need back-office features.
If your staff runs Windows PCs and you’d rather not introduce iPads: eHopper Essential is the only serious free option that fits. Go in knowing the add-on costs and verify processor flexibility before touching their hardware bundles.
If you’re doing more than $15,000/month in card volume: You shouldn’t be on any free tier. Run the interchange-plus math with Helcim or a direct merchant account, pick a $30–$60/month subscription POS that unlocks real reporting, and treat the subscription fee as the cost of getting your processing rate down. The free tier is a starting point, not a permanent home.
Free POS systems are genuinely useful — not a gimmick. The discipline is knowing exactly which number triggers the upgrade, and not letting a $0 software bill talk you into ignoring $400/month in processing fees that a $60 subscription would cut in half.
