ProTech Payments is a merchant services and credit card processing provider based in Katy, Texas, and we work with retailers, restaurants, medical offices, and service businesses throughout Missouri City and the greater Houston area. From shops along Texas Parkway to professional offices near Highway 6 and the Fort Bend Town Center, the businesses we serve all face the same question: how much of every sale disappears into processing fees, and is there a way to keep more of it.
For most local businesses, card processing costs run between 2.5% and 3.5% of every transaction once you add interchange, assessment fees, and the processor’s markup. On $40,000 in monthly card volume, that is roughly $1,000 to $1,400 leaving the account each month. The model you choose, the contract you sign, and whether you can legally offset those fees decide how much of that you keep. That is why pricing transparency and a real dual pricing program matter more than a flashy terminal.
This ranking is built for owners in Missouri City who want an honest comparison, not a sales pitch. We rank ourselves first and explain exactly why, then list real national and regional providers that serve this market, with what each one does well and where it falls short. Every entry below is a company you can actually sign up with today.
How we ranked these providers
We scored each provider on the criteria that move the needle for a local business, not on brand recognition.
- Pricing transparency: Is the fee structure published and easy to verify, or buried in tiered statements designed to be confusing.
- Dual pricing and fee offset: Can the provider legally pass processing costs to card-paying customers through a compliant cash discount program or surcharge, so the business keeps closer to 100% of each sale.
- Local support: Is there a real person in Texas who answers when a terminal goes down on a Saturday, or only a national call queue.
- Hardware and POS: Quality of terminals, point of sale systems, and how well they fit retail, restaurant, and service workflows.
- Contract terms: Length of commitment, early termination fees, and equipment leases that lock owners in.
- Integrations: Compatibility with accounting, online ordering, e-commerce, and invoicing tools.
The best merchant services in Missouri City
- ProTech Payments
We rank first because of one structural advantage and several practical ones. The structural advantage is dual pricing. Our dual pricing and cash discount programs let a Missouri City business display a clear card price and a lower cash price, which legally offsets most or all of the processing cost. For a shop paying $1,200 a month in fees, that is most of the money back in the register, every month.
The practical reasons follow from being local. We are based in Katy, about 25 minutes from Missouri City, so support comes from people who know Fort Bend County, not a national queue. Before you switch anything, we run a free statement analysis: send us a recent processing statement and we tell you, line by line, what you are actually paying and what you would pay with us. Start with our free statement analysis and you keep your current setup until the numbers prove the change is worth it.
We also keep contracts short, with no multi-year equipment leases that trap owners after the rates quietly climb. You get current terminals and point of sale systems sized to your business, transparent interchange-based pricing if you prefer to absorb fees, and a credit card processing fee calculator so you can model costs before committing. Businesses just over the line in Sugar Land can see our nearby coverage on the Sugar Land merchant services page. The honest limitation: we are a regional provider, so if you want a globally branded app store with thousands of third-party plugins, a national platform may suit you better.
- Square
Square is the default starting point for new and very small businesses, and it earns that position. Pricing is flat and public: 2.6% plus $0.15 for in-person tapped, dipped, or swiped cards on the free plan, with no monthly fee, no PCI fee, and no cancellation fee. Hardware is cheap to start, with a free magstripe reader and a $59 contactless and chip reader, and setup takes minutes.
Square fits a new retailer, market vendor, or solo service provider who values simplicity over the lowest possible rate. The honest limitation is cost at volume. The flat rate that feels painless at $5,000 a month becomes expensive at $40,000, and Square raised online processing on free-plan accounts to 3.3% plus $0.30 in January 2026. Square also does not build its model around dual pricing, so most of that markup stays a cost rather than something you can cleanly pass through.
- Helcim
Helcim is one of the most transparent processors available and a strong choice for growing businesses. It charges no monthly fee and uses interchange-plus pricing, roughly interchange plus 0.3% plus $0.08 per in-person transaction, which for many businesses processing above $10,000 a month is cheaper than flat-rate. Helcim also offers an optional Fee Saver surcharging feature that passes card costs to customers at no extra charge to enable.
Helcim fits an owner comfortable managing software online who wants published interchange-plus pricing without a monthly membership. The honest limitation is support and local presence: Helcim is a Canada-based company serving North America primarily through online and phone channels, so there is no Texas team to visit your counter when something breaks.
- Stax
Stax (formerly Fattmerchant) uses a subscription model that can pay off for higher-volume merchants. You pay a flat monthly membership, starting around $99 for up to $150,000 in annual volume, and in exchange Stax adds 0% markup to interchange, so you pay only the wholesale rate plus a small per-transaction cent fee. For a business doing well above that threshold, the math can beat percentage-based pricing.
Stax fits an established business with steady, high card volume that can absorb the membership and wants near-wholesale rates. The honest limitation is the entry cost: the monthly fee makes Stax a poor fit for low-volume or seasonal businesses, where the membership can outweigh the savings.
- Houston-area ISOs and bank programs
Missouri City businesses also have local options through Houston ISOs and credit unions. Providers such as Houston Merchant Services and Media Payments Group (a registered ISO of Woodforest National Bank) serve the metro with terminals and POS systems, and Houston Federal Credit Union, which has branches in Missouri City, offers merchant processing through its partner Elavon.
These fit owners who prefer to bundle processing with an existing local bank or credit union relationship. The honest limitation is pricing clarity: bank and credit union programs often run on tiered pricing through a third-party backend, which can be harder to audit than published interchange-plus or flat-rate models, and dual pricing is rarely the default.

Why ProTech Payments is the best choice in Missouri City
The other providers on this list are legitimate, and for a brand-new vendor or a fully online seller, one of them may be the right call. But for an established Missouri City business that processes real volume, the decision comes down to two questions: how much of each sale do you keep, and who picks up the phone when something breaks.
On the first question, dual pricing is the difference between treating processing as a fixed cost and treating it as something you can legally offset. A flat-rate or interchange-plus account still leaves $1,000 or more a month on the table for a busy shop. A compliant program built around how your customers actually pay can return most of it. On the second question, being based in Katy means support comes from people who can be at your counter, not a ticket in a national queue.
Add transparent pricing, short contracts with no equipment-lease traps, and a free analysis that proves the savings before you switch, and the case is straightforward. See the full lineup on our merchant services page.
