Credit card processing for a small business is the set of services that move money from a customer’s Visa, Mastercard, Discover, or American Express card into your bank account, minus the fees each party in that chain charges. The “best” processor is the one that prices those fees transparently, settles funds quickly, and matches the way you actually take payments, whether that is a Clover terminal at a Katy storefront, an online checkout, or a phone order keyed into a virtual terminal. ProTech Payments, based at 25140 Kingsland Blvd STE 180 in Katy, Texas, sets up processing for small businesses across Houston, Fort Bend County, and the wider Texas market, and the difference between a good account and a bad one routinely runs 0.5% to 1.5% of total card volume.
For a shop running $40,000 a month in card sales, that spread is $200 to $600 per month, or up to $7,200 a year, kept or lost on pricing model alone. The number that matters is your effective rate: total fees divided by total card volume. Most owners never calculate it, which is exactly why a free statement analysis is the first step before signing anything.
This guide breaks down how processing works, the pricing models you will be quoted, costs by business type, how the major players compare, and the Texas-specific options (dual pricing, cash discount, surcharging) that can cut your card fees to near zero when set up legally.
How credit card processing actually works
Every card sale passes through four parties. Understanding the chain tells you where your fees come from and which ones are negotiable.
The four-party model
When a customer taps or dips a card, the request travels from your terminal or gateway to your processor (the company handling the transaction), then to the card networks (Visa and Mastercard), then to the issuing bank that gave the customer the card. The issuer approves or declines, the funds route back, and money lands in your account, usually within one to two business days. A merchant account is the holding account that makes this possible, and a payment gateway is the software layer that connects an online store to the processor.
Where the fees come from
Three fee buckets exist. Interchange goes to the customer’s issuing bank and is the largest piece, set by Visa and Mastercard and identical for every processor. Assessments go to the card networks themselves and run roughly 0.13% to 0.15%. The markup is what your processor keeps, and it is the only part anyone can negotiate. A rewards Visa card might carry 1.65% plus $0.10 in interchange, while a basic debit card regulated under the Durbin Amendment caps the issuer’s cut at $0.21 plus 0.05%. Our interchange fees explained guide breaks down each category in detail.
Hardware and security
In-person payments run on EMV chip terminals that generate a unique code per transaction, which shifted counterfeit-fraud liability to merchants who fail to use chip readers after October 2015. Most small businesses now run point-of-sale systems like Clover, built on the Fiserv (formerly First Data) platform, which handle EMV, contactless taps, and inventory in one device. PCI DSS compliance is mandatory for anyone storing or transmitting card data, and non-compliance fees of $20 to $40 a month are a common hidden line item.
Pricing models you will be quoted
The pricing model decides your effective rate more than any single rate quote. Three dominate the small-business market.
Interchange-plus
Interchange-plus passes the true interchange cost straight through and adds a fixed markup, for example interchange plus 0.30% plus $0.10. This is the most transparent model because you can see exactly what the processor keeps. It is the recommended structure for most businesses above roughly $10,000 a month in volume. See our interchange-plus pricing explained breakdown for the math.
Flat-rate
Flat-rate charges one blended percentage regardless of card type, such as Square’s 2.6% plus $0.10 for in-person or Stripe’s 2.9% plus $0.30 for online. It is simple and predictable, which is why micro-merchants like it, but it overcharges on debit and regulated cards where true cost is far lower. Above $8,000 to $10,000 a month, flat-rate usually costs more than interchange-plus.
Tiered
Tiered pricing sorts transactions into qualified, mid-qualified, and non-qualified buckets at rates the processor defines. It is the least transparent model and the one most likely to hide margin, because the processor decides which bucket each card lands in. Avoid it when a clearer option exists.
| Pricing model | Typical cost | Transparency | Best fit |
|---|---|---|---|
| Interchange-plus | Interchange + 0.20% to 0.50% + $0.10 | High | Most businesses over $10k/mo |
| Flat-rate | 2.6% to 2.9% + $0.10 to $0.30 | Medium | Micro-merchants, low volume |
| Tiered | 1.7% to 3.5% by “bucket” | Low | Rarely the best choice |
| Dual pricing / cash discount | Near 0% to merchant | High | Texas businesses willing to pass fees |
What processing costs by business type
Effective rates vary by how cards are presented and what average tickets look like. Card-present sales cost less than card-not-present because fraud risk is lower.
Retail and restaurants
Brick-and-mortar retail merchant services and restaurant merchant services typically land at a 2.0% to 2.5% effective rate on interchange-plus, helped by chip-and-tap card-present pricing. Restaurants add tip adjustment and table management on the POS, which Clover handles natively.
Service and professional businesses
Auto repair, salons, and home services often take a mix of in-person and phone payments. Auto repair merchant services and home services merchant services accounts usually pair a terminal with a virtual terminal for keyed deposits. Professional and B2B sellers benefit from Level 2 and Level 3 data, which can drop interchange on commercial cards by 0.50% to 1.00% per transaction.
E-commerce and high-risk
Online sellers run card-not-present rates closer to 2.5% to 3.0% and need a payment gateway plus tokenization. Industries flagged for chargeback or regulatory risk need high-risk merchant accounts, which carry higher rates but provide stable, non-frozen processing that aggregators like Square cannot guarantee.
Comparing the best processors for small business
The “best” choice depends on volume, channel mix, and whether you want to pass fees to customers. Here is how the common options compare for a typical small business.
| Provider type | Pricing | Funding speed | Account stability | Texas fee-pass option |
|---|---|---|---|---|
| ProTech Payments (Fiserv/Clover) | Interchange-plus or dual pricing | 1 to 2 business days | Dedicated merchant account | Yes, fully supported |
| Square | Flat 2.6% + $0.10 | 1 to 2 days | Aggregator, freeze risk | Limited |
| Stripe | Flat 2.9% + $0.30 online | 2 days | Aggregator, freeze risk | Limited |
| Bank-referred ISO | Often tiered | Varies | Varies | Varies |
Why a dedicated merchant account beats an aggregator
Square and Stripe pool many merchants under one account, which makes signup fast but exposes you to sudden holds or terminations if a transaction looks unusual. A dedicated merchant account through ProTech underwrites your business individually, so funds are less likely to be frozen, and you get a named representative in Katy rather than a support queue. For a deeper comparison see Clover vs Square and our guide to choosing a payment processor for a small business.
Matching the processor to your channel
Counter sales want in-store payments on a Clover device. Field techs and pop-ups want mobile payments. Websites want online payments wired to a gateway. Recurring invoicing wants ACH. ProTech configures all of these under one merchant services account so reporting stays consolidated.
Cutting fees to near zero in Texas
Texas law permits passing card-acceptance costs to customers, which is the single biggest lever a small business has on processing expense. Done correctly, it can take card fees close to zero.
Dual pricing and cash discount
A dual-pricing program displays two prices, one for card and one for cash, and the card price absorbs the processing cost. A cash discount program posts the card price and gives a discount for paying cash. Both are legal in Texas when disclosed properly, and our cash discount program in Texas guide covers the signage and receipt rules.
Surcharging rules
Surcharging adds a fee only to credit transactions (never debit) and is capped at the lesser of your cost or 3% under network rules. Texas surcharge enforcement has shifted since the 2018 court rulings, so the disclosure has to be exact. Read credit card surcharge laws in Texas before turning it on, and model the savings with the dual pricing savings calculator.
What the savings look like
A Katy restaurant processing $50,000 a month at a 2.4% effective rate pays about $1,200 monthly in fees. Moving to a compliant dual-pricing program can cut the merchant’s share to under $100, keeping more than $13,000 a year. ProTech serves businesses across Katy, Houston, and Sugar Land with locally configured programs.
Common mistakes that cost small businesses money
Most overpayment comes from a handful of avoidable errors.
Signing on the headline rate
The advertised “qualified” rate applies to a narrow slice of cards. Rewards and commercial cards fall into pricier buckets, so the headline rate rarely reflects your real cost. Always compare effective rate, not the teaser.
Ignoring junk fees
PCI non-compliance fees, statement fees, batch fees, and annual fees stack up to $30 to $80 a month outside the processing rate. A statement analysis surfaces every one. Staying current on PCI compliance eliminates the non-compliance charge entirely.
Long-term contracts and early termination fees
Many processors lock merchants into three-year terms with $300 to $500 early termination fees. ProTech offers month-to-month options so you are never trapped in a bad rate. Pair that with active chargeback management to protect revenue from disputes, covered in our chargeback prevention playbook.
Frequently asked questions
What is the best credit card processing for a small business?
The best processor is the one with the lowest effective rate for your card mix, transparent interchange-plus or dual pricing, fast funding, and a dedicated merchant account rather than an aggregator. For most Texas small businesses, that means a Fiserv-backed account configured by a local provider like ProTech Payments, often paired with a dual-pricing program to cut fees.
How much should a small business pay in processing fees?
A fair effective rate on interchange-plus runs 2.0% to 2.5% for card-present retail and restaurants, and 2.5% to 3.0% for card-not-present online sales. If your statement shows an effective rate above 3%, you are likely overpaying through tiered pricing or junk fees, and a statement analysis will confirm it.
Is Square or Stripe good for a small business?
Square and Stripe are fine for very low volume because setup is instant and pricing is flat. Above roughly $8,000 to $10,000 a month they cost more than interchange-plus, and both pool funds in aggregator accounts that can be frozen without warning. Growing businesses usually save by moving to a dedicated merchant account.
Can I avoid credit card processing fees in Texas?
Yes, within limits. Texas law allows dual pricing, cash discounting, and surcharging, all of which pass the card-acceptance cost to the customer who chooses to pay by card. Set up correctly with proper disclosure, these programs can reduce the merchant’s processing cost to near zero, which is why many Houston-area businesses adopt them.
What is the difference between a merchant account and a payment processor?
A merchant account is the bank account that temporarily holds card funds before they settle to your business checking. A payment processor is the company that routes the transaction through the card networks and into that account. A full service like ProTech provides both plus the gateway, hardware, and PCI support.
How fast will I get my money?
With a dedicated merchant account, card funds typically settle in one to two business days after batch-out. Funding speed depends on your bank and the batch cutoff time, not just the processor, and same-day options exist for qualifying accounts.
