Payment Processing Rate Hikes 2026: What SpotOn and Fiserv Mean for Your Business

SpotOn's May 2026 Increase: 0.15% on Most Cards, 0.35% on Amex

SpotOn, the merchant services provider popular with restaurants and retail shops, notified clients in late February that it will raise rates effective May 1, 2026. For Visa, Mastercard, and Discover transactions, the increase is 0.15% across the board. American Express card transactions get a steeper hike: 0.35%.

That doesn't sound like much on a single sale. But consider a business processing $500,000 in card payments annually. The 0.15% increase adds $750 per year in additional fees — and that's before Amex surcharges. If 20% of your volume is Amex, you're looking at another $350. Total extra cost: over $1,000 annually, with no new services attached.

SpotOn framed the move as necessary to "continue investing in technology and support." The company has been aggressively pushing its AI-powered analytics tools and upgraded point-of-sale hardware. But for merchants already on tight margins, this is a direct hit to profitability.

Fiserv's July 2026 Interchange Plus Increase: $0.03 + 0.05%

Fiserv, one of the largest payment processors in the country (you might know them through First Data or Clover), is taking a different approach. Instead of a flat percentage increase, they're raising the Interchange Plus pricing model — the most common transparent pricing scheme for small businesses.

Effective July 1, 2026, Fiserv will add 0.05% plus $0.03 per transaction to the interchange-plus markup. That means every swipe, dip, or tap now costs three more cents and a fraction of a percent more. For a business doing 2,000 transactions per month at an average ticket of $50, the per-transaction fee alone adds $60 per month — $720 annually. The percentage piece tacks on another $600. Total: roughly $1,320 extra per year from Fiserv alone.

This is notable because Interchange Plus pricing is supposed to be transparent and predictable. But processors can still adjust their markup. Fiserv's move follows a pattern: as card networks keep raising interchange fees, processors are passing more of that cost downstream. Add in Fiserv's heavy investment in cloud-based POS systems and data security upgrades, and the rationale becomes clearer — even if it stings.

Why Now? The Hidden Drivers Behind These Hikes

You might wonder: "Aren't payment processors supposed to get cheaper over time?" Not necessarily. The industry is undergoing a massive transformation. Processors are pouring money into three areas that don't come cheap:

• Artificial intelligence for fraud detection, chargeback prevention, and customer analytics
• Hardware refreshes as older terminals reach end-of-life and new contactless/NFC devices roll out
• Value-added services like inventory management, marketing tools, and employee scheduling

SpotOn and Fiserv are both public-facing about these investments. In recent earnings calls, both companies cited rising technology costs as a key reason for repricing. Meanwhile, Visa and Mastercard continue raising their own network fees twice a year. That dual pressure — higher interchange from the networks plus higher processor markup — means merchants are getting squeezed from both sides.

What Merchants Should Do Right Now

You've got a window before these increases take effect. Here's a practical game plan.

Read Your Merchant Statement — Really Read It

Most business owners toss these statements aside. Don't. Look for the line that says "Interchange Plus" or "Qualified Rate." Calculate your effective rate (total fees divided by total volume). If it's above 2.5% for swiped debit or 3.5% for keyed-in cards, you may already be overpaying.

Ask Your Processor for a Renewal Quote

Call SpotOn or Fiserv directly. Tell them you're aware of the upcoming increases and ask if they can offer a loyalty discount or a fixed-rate plan. Some processors will negotiate to keep you from shopping around.

Compare Multiple Processors Before May 1

The simplest defense is competition. Other processors like Stripe, Square, or Heartland may not have announced rate increases yet. But don't assume they're immune. The best way to protect your margins is to run a comparison using a platform that lets you see side-by-side pricing.

The Bottom Line: Don't Wait Until July

SpotOn's May increase and Fiserv's July hike are part of a broader trend. More processors will likely follow. Acting now gives you leverage — you can lock in a rate before the next round of increases hits.

Payment processing is a fixed cost that can fluctuate wildly if you're not watching. A 0.15% bump here, a three-cent fee there — it adds up fast. The businesses that do best in this environment are the ones that treat their merchant services like any other operating expense: shop it, negotiate it, and optimize it.
