Why POS Software Should Be Free (And How We Make It Work)
Most POS companies charge $69–$165/month before you ring a single sale. Here's why that model is broken — and how Simpli POS stays free forever.
Most café owners and restaurant operators have heard the pitch: “Our POS starts at $69 a month.” Some pay $165. A few with add-ons push past $200. And that’s before a single transaction has been rung.
The question nobody seems to ask is: why does software that helps you sell things cost money before you sell anything?
The Traditional POS Model Is Backwards
Here’s how the standard POS business model works: you pay a monthly subscription for software, you pay for (or lease) proprietary hardware, and then you also pay processing fees on every card transaction. The software company earns regardless of whether your business succeeds.
This made some sense in the 1990s, when POS systems were genuinely complex hardware-software integrations that required installation engineers and dedicated support staff. But a modern POS is, at its core, a mobile app connected to a payment terminal. The marginal cost of running that software for one more merchant is close to zero.
So why are the fees still there? Because they can be. The legacy players built pricing expectations into the market, and most buyers assume that “enterprise software costs money.” The incumbents have little incentive to break that assumption.
How Card Processing Economics Change the Equation
Every time a customer pays by card at your register, a small fee flows through a network of entities: your bank, the card network (Visa or Mastercard), and the issuing bank that gave your customer their card. This is called interchange.
Interchange fees typically run between 1.5% and 2.5% of the transaction, depending on the card type. Premium rewards cards cost more to accept. Debit cards cost less.
A POS company that also processes your card payments earns on that interchange flow — either directly or via a markup on top of the base rate. That margin, earned on every transaction, can more than cover the cost of running great software.
The math: a café doing $20,000/month in card volume generates meaningful processing revenue on its own. That revenue can fund free software, free support, and product development — without charging the merchant a subscription before they’ve earned a single dollar.
Interchange-Plus vs. Flat Rate: What You’re Actually Paying
Most POS companies that bundle “free” processing use flat-rate pricing: a fixed percentage (say, 2.6%) on every transaction, regardless of card type.
Flat rate is simple to understand but expensive at volume. That 2.6% includes the interchange (say, 1.8% for a consumer Visa) plus the processor’s margin (0.8%). You pay the same rate on a cheap debit card as on a premium rewards card.
Interchange-plus pricing is different. You pay the actual interchange cost the card networks charge, plus a small, fixed markup. When you swipe a debit card (lower interchange), you pay less. When you swipe a premium rewards card (higher interchange), you pay more — but the margin on top stays small and transparent.
For a business doing $15,000 or more per month in card volume, the difference between flat-rate and interchange-plus can run $50–$150/month — more than the cost of most POS subscriptions.
What “Free” Actually Means at Simpli POS
Simpli POS is free to download, free to install, and free to run. No setup fees. No monthly subscription. No per-terminal fees. No contract.
What we earn: a margin on card processing, if and when you choose to run payments through our integrated merchant account. You are not required to use our processing. If you bring your own payment provider, the POS software stays free.
What’s included at $0/mo:
- Full restaurant features: floor maps, coursing, seat-aware ordering, split checks
- Modifier groups for cafés and bubble tea shops
- Kitchen display routing
- Employee PINs and role permissions
- Offline mode — you keep taking orders even if the internet drops
- Sales reporting and exports
- Multi-location management
There are no hidden “advanced” tiers that lock useful features behind a paywall. The features your business needs on day one are there on day one.
The Trade-Off You Should Know About
Transparency matters, so here it is: our model works best when you process cards through us. Our interchange-plus rates are published on our website — if you have a custom processing arrangement that beats them, keep it. The software stays free either way.
We also don’t have a white-glove onboarding team to fly to your location. Simpli POS is built for self-serve setup — the average terminal takes under 90 seconds to configure. If you need a dedicated account manager and weeks of on-site training, a system like Toast may be the better fit for your operation.
What This Means for Your Business
Switching from a $100/month POS subscription to free software doesn’t just save $1,200 a year. It changes the risk calculation of opening a new location, hiring a new employee, or weathering a slow quarter.
POS software that costs money before you earn money is, at its core, a bet against small businesses. The free model is a bet that if we help your business succeed, you’ll process cards with us — and that’s enough for both sides.
If you’re curious whether the numbers work for your volume, the best way to find out is to download the app, run a few transactions, and compare your next statement.
