Ready to switch?
No commitments. No credit card. Just a 30-minute walkthrough of the platform.
Book a demoMost POS systems force you to use their built-in payment processor. You didn't choose it. You can't negotiate the rate. And every time a customer taps their card, the POS company takes a cut. The Nilson Report puts U.S. merchant card processing fees at over $172 billion in 2023. A significant portion of that flows directly to POS vendors who bundle processing into their software, whether you like the rate or not.
A processor-agnostic POS doesn't bundle payment processing into the software. You pick your processor, negotiate your rate, and connect it to the system. The POS handles sales. The processor handles payments. They're separate.
This matters because it puts you in control. You're not locked into a rate that someone else decided. You shop the market. You find the best deal. And if a better option comes along next year, you switch without changing your entire POS system.
On $50,000/month in card sales, bundled POS processors charge between $1,292 and $1,514 per month in fees, based on published rate sheets from the major bundled providers. That's $15,500 to $18,200 per year just in transaction fees. Most merchants don't realize how much they're paying because the fees are deducted automatically before settlement.
Here's what the math looks like at $50,000/month with a $35 average ticket (roughly 1,429 transactions/month):
Now compare that to a merchant using a processor like Helcim, which offers interchange-plus pricing. Their effective rate for a $50K/month merchant lands around 1.7–2.0% with no monthly minimum. That's $850–$1,000/month, or $10,200–$12,000/year.
The difference? Up to $6,500 per year. Just by choosing your own processor.
The business model is simple. McKinsey's 2024 Global Payments Report puts global payment processing revenue at $2.4 trillion in 2023. POS vendors want a piece of that. Software subscriptions are competitive, so many companies subsidize their software price by making it back on processing.
That's why one popular provider offers a "free" plan. The software costs $0. But every transaction costs 2.6% + 15 cents. On a $600K annual revenue business, that's $18,172 per year flowing to the POS company, not to a processor you chose.
Think about it this way. If your POS vendor makes money every time you process a payment, they're incentivized to process more of your payments, not to make your business more efficient. Their revenue goes up when your sales go up. But so do your fees.
A flat-rate software company has a different incentive. They make the same $49.99 whether you sell $10,000 or $100,000 in a month. Their incentive is to make the software good enough that you keep paying. That's it.
With a processor-agnostic system, you can connect virtually any payment processor. There are hundreds of registered payment processors in the U.S. alone. Here are some popular options merchants use:
You get to compare. You get to negotiate. And if your processor raises rates or the service slips, you switch without losing your POS data, your sales history, or your workflow.
Shoppa charges $49.99/month for the full platform: POS, BackOffice, Webstore, inventory management, unlimited users, and API access. Shoppa doesn't charge transaction fees on top of what your processor charges. Your payment processing relationship is entirely between you and the processor you choose.
This model only works if the software is genuinely good enough to justify the subscription. That's the accountability built into flat-rate pricing. We can't hide behind cheap software subsidized by processing fees. The product has to stand on its own.
A merchant doing $600,000/year in revenue ($50K/month):
That's a savings of $4,000 to $6,500 per year depending on which platform you're leaving. For a merchant doing $1M/year, the gap widens accordingly.
Before you switch, make sure the system actually delivers on processor freedom. Not every POS that claims to be "open" truly is. Here's what to verify:
We've talked to merchants who spent $3,000+ on proprietary hardware only to discover it's a paperweight after switching POS providers. Hardware lock-in is the silent killer of merchant flexibility.
Not exactly. You choose a processor, but the POS platform handles the technical integration. Most merchants complete onboarding in under 48 hours. You pick the provider, they handle the gateway connection.
Yes. Modern processors like Helcim, Stax, and Payment Depot all support NFC, Apple Pay, Google Pay, and chip cards. Your processor choice doesn't limit your acceptance methods.
A good processor-agnostic POS should support offline mode and cash transactions regardless of processor status. The POS and the processor are separate systems. If one has an outage, the other still functions for non-card transactions.
Most processors provide detailed daily settlement reports. You'll reconcile directly with your processor rather than through the POS vendor. Many merchants prefer this because they get clearer visibility into interchange rates and fee breakdowns.
Your POS vendor shouldn't be your payment processor. Those are two different jobs, and combining them creates a conflict of interest that costs you thousands per year.
The math at $50K/month: the largest bundled provider takes $18,172/year. Helcim through a processor-agnostic POS runs roughly $11,000/year. The $7,000 difference isn't a rounding error. It's the cost of not thinking about this.
Your checkout. Your processor. Your rates.
