Heartland quotes you 1.9%. Square quotes you 2.6% + $0.10. Shift4 sends a rep who won't give you a number until you sign an NDA. If you run a small business in Connecticut, Massachusetts, Rhode Island, or anywhere else in New England — here's the honest comparison nobody in the industry will give you.
Why "Best Processor" Depends on Your Business Type
There's no single best payment processor for every business. A restaurant with $40,000/month in card volume and mostly in-person transactions has different needs than a B2B wholesaler processing $200,000/month with high average ticket sizes. The right answer depends on three things: your monthly volume, your average transaction size, and whether you can implement a cash discount program.
That said, there are processors who consistently overcharge New England merchants through hidden fees, long-term contracts, and pricing structures designed to be unauditable. This guide names them.
Forget the quoted rate. Calculate your effective rate: total fees paid last month ÷ total card volume. If it's above 2.8%, you're overpaying regardless of what your contract says. The average New England merchant we audit comes in at 3.4–4.2%.
Side-by-Side Comparison (2026)
| Processor | Effective Rate (typical) | Monthly Fees | Contract | Hidden Fees? | BBB Complaints |
|---|---|---|---|---|---|
| Heartland | ~3.5–4.5% | $25–$50+ | 3-year (auto-renews) | Many (PCI, regulatory, batch) | 880+ |
| Square | ~2.6–3.5% | $0 (basic) | None | Some (keyed-in rate jumps) | Moderate |
| Shift4 | ~3.0–4.2% | $25–$75+ | Multi-year | Many (integration fees, gateway) | Significant |
| Worldpay | ~3.8–5.0% | $40–$80+ | 3-year + ETF | Extensive | Significant |
| Clover | ~2.3–3.5% | $14.95–$84.95 | Tied to hardware lease | Moderate | Some |
| FeeShield | 2.5% flat (or near-zero with cash discount) | $0 | Month-to-month | None | 0 |
Processor Breakdown: What They Don't Tell You
Heartland Payments
Effective rate: ~3.5–4.5%Heartland is the dominant processor for New England hospitality and restaurant businesses — not because they're the best, but because their sales force is aggressive and their contracts are sticky. The 3-year auto-renewing contract includes an early termination fee of $295–$995. Their "interchange-plus" pricing sounds transparent but adds a dozen line-item fees that inflate your actual cost well above the quoted markup.
What works
- Strong restaurant/hospitality POS integrations
- Local sales rep coverage across New England
- Payroll integration available
What doesn't
- 3-year contract with auto-renewal trap
- PCI non-compliance fees ($19.95/mo if you miss annual certification)
- Regulatory fee (~$0.10/transaction) added silently
- 880+ BBB complaints nationally
Square
Effective rate: ~2.6–3.5%Square is the easiest processor to start with — no setup, no monthly fees on the basic plan, readable flat-rate pricing. For a new business under $10,000/month in volume, it's defensible. But the rate (2.6% + $0.10 in-person) gets expensive fast at scale, and keyed-in transactions jump to 3.5% + $0.15. There's no negotiation — you're locked into their published rates.
What works
- No contract, cancel anytime
- Free POS software and hardware starter options
- Transparent flat-rate pricing
What doesn't
- Rate doesn't scale — expensive at $50k+/month
- No cash discounting or surcharging support
- Account holds/freezes common with high-volume merchants
Shift4 Payments
Effective rate: ~3.0–4.2%Shift4 acquired several regional processors and now operates under multiple brand names across New England. Their restaurant technology stack (Harbortouch, SkyTab) is solid, but the pricing model bundles processing with hardware and software in a way that makes it nearly impossible to calculate your true cost. Contracts often include hardware lease obligations that survive termination.
What works
- Integrated POS for restaurants and hospitality
- Solid uptime and support infrastructure
What doesn't
- Bundled pricing hides true processing cost
- Gateway fees add 0.15–0.25% on top of processing
- Long-term contracts with significant ETFs
Worldpay (FIS)
Effective rate: ~3.8–5.0%Worldpay is the most expensive processor on this list for most New England small businesses. They target mid-market businesses with complex needs and wrap extensive fee schedules in contracts that require a lawyer to parse. If you're processing under $500k/year, there is almost no reason to be with Worldpay. Yet they have tens of thousands of New England merchants locked into 3-year contracts.
What works
- Enterprise-scale integrations (ERP, ERP)
- Multi-currency support for international businesses
What doesn't
- Highest effective rates of any major processor
- 3-year contract + $495–$995 ETF
- Statement fees, regulatory fees, PCI fees, annual fees
- Customer service ranked consistently poor
Clover (Fiserv)
Effective rate: ~2.3–3.5%Clover hardware is genuinely good — the POS systems are well-designed and widely adopted in New England retail and restaurants. The trap is that Clover is sold through resellers (Fiserv, banks, ISOs) who set their own processing rates. A Clover device sold through your local bank may process at 3.5%, while the same device through a different reseller processes at 2.3%. The hardware lease often locks you to a single processor.
What works
- Best-in-class POS hardware design
- Strong app marketplace for add-ons
- Widely supported by local banks and ISOs
What doesn't
- Rate set by reseller — varies wildly
- Hardware lease locks you to that reseller's rates
- Monthly software fees ($14.95–$84.95) on top of processing
FeeShield (via Echelon Payments)
Effective rate: 2.5% flat (or ~0% with cash discount)FeeShield works exclusively with Echelon Payments — a processor built for New England businesses that want full transparency. The pricing is 2.5% flat, no hidden fees, no contracts, no PCI fees, no regulatory fees. For eligible businesses, a cash discount program can reduce your effective processing cost to near-zero by passing the fee to card-paying customers.
What works
- 2.5% flat rate, one number on your statement
- Cash discount option: near-zero net processing cost
- Month-to-month, cancel anytime
- No PCI fees, no regulatory fees, no batch fees
- High-risk merchant support (95% approval rate)
What doesn't
- Not ideal for very low-volume hobbyist sellers
- Cash discount requires minor program setup

Get Your Free Fee AuditThe Hidden Fee Problem Every New England Merchant Faces
Every processor above except FeeShield uses some variant of tiered pricing or interchange-plus with add-on fees. The result is a statement you can't audit. When you divide your total monthly fees by your monthly volume, the effective rate is almost always materially higher than the rate you were quoted.
The fees that inflate your effective rate most often:
- PCI compliance fee — $9.95–$24.95/month, charged regardless of compliance status
- PCI non-compliance fee — $29.95–$99/month if you miss annual self-assessment
- Regulatory/assessment fee — $0.03–$0.15 per transaction, labeled as "pass-through" but marked up
- Batch/settlement fee — $0.05–$0.25 per daily batch
- Statement fee — $5–$15/month for a PDF
- Annual fee — $75–$150, billed quietly each year
- Minimum monthly fee — $25–$50 charged if your processing fees don't hit a threshold
A merchant processing $30,000/month at a quoted rate of 2.2% can easily end up paying $1,200–$1,500 in total fees — an effective rate of 4–5% — once all of these are counted. Our full guide to hidden fees → breaks down every one of them.
Heartland, Shift4, and Worldpay all use auto-renewing multi-year contracts. If you don't send a certified letter of cancellation 30–90 days before the anniversary date, your contract automatically renews for another full term — with an early termination fee to exit. Read your contract addendum for the specific notice window. It's not in the main contract.
What Should New England Small Businesses Actually Do?
Here's the honest answer for different business types:
Under $10,000/month in card volume
Square is defensible. The 2.6% + $0.10 rate is above what you'd pay at scale, but you have no contract and minimal setup cost. Don't sign a multi-year contract with any processor at this volume — your negotiating position will improve as you grow.
$10,000–$100,000/month
This is where flat-rate pricing with a reputable processor (like FeeShield/Echelon) becomes significantly better than any tiered or interchange-plus option. The math is simple: at $50,000/month, the difference between 2.5% and 3.5% is $500/month, or $6,000/year. Use our free fee calculator → to run the numbers for your actual volume.
$100,000+/month or high average ticket
Cash discounting or surcharging is worth exploring. At $100,000/month, a cash discount program that brings your effective rate to 0.5% saves roughly $2,000/month versus a 2.5% flat rate. FeeShield's audit includes a cash discount analysis for businesses at this scale.
High-risk verticals (cannabis, CBD, firearms, etc.)
Most processors on this list won't serve you, or will charge 4–7% and drop you without warning. See our high-risk merchant guide → for the specifics.
How to Switch Processors Without Interrupting Your Business
Switching is less disruptive than most merchants expect. The typical timeline:
- Submit your current statement for a free FeeShield audit — takes 5 minutes
- Receive your comparison — usually same day
- Sign up and receive new equipment — 3–5 business days
- Parallel run for one week — process on both while staff trains
- Cancel old processor — send written notice per your contract terms
The biggest risk is the cancellation process with your old processor. Review your contract for the cancellation notice requirement before starting. Some processors (Heartland, Worldpay) require certified mail to specific addresses — not just a phone call.
Before switching, get a clear picture of what you're paying now. Our statement audit guide → walks you through the calculation. You want to know your true effective rate before comparing — not just the rate line on your statement.
Frequently Asked Questions
Can I keep my Clover hardware if I switch processors?
Sometimes — it depends on who sold you the device. Clover devices purchased through Fiserv are locked to Fiserv resellers. Devices purchased through some third-party ISOs can be unlocked. Ask FeeShield before assuming either way — the hardware situation needs to be confirmed before committing to a switch.
How do I get out of a Heartland or Worldpay contract?
Send a written cancellation notice via certified mail to the address in your contract addendum (not the general customer service address). Include your merchant ID, business name, and desired cancellation date. Send it within the cancellation window specified in your contract — usually 30–90 days before your anniversary date. Keep the tracking number. If you're outside the window, you'll need to pay the ETF or wait for the next window.
Is FeeShield available outside Connecticut and Massachusetts?
Yes. FeeShield serves businesses across all six New England states (CT, MA, RI, NH, VT, ME) and is expanding nationally. The fee audit and cash discount programs are available regardless of location.
