The Processor Scoreboard

Merchant One

A Miami-based independent sales organization that resells Fiserv processing and Clover terminals. No lawsuits or federal actions on record, but a complaint file dominated by the same story: a three-year contract the merchant says nobody mentioned, and a termination fee that arrives when they try to leave.

Who you are actually signing with

Merchant One is not a bank or a processor. It is an independent sales organization based in the Miami area that resells Fiserv’s processing and Clover point-of-sale systems. Your account runs on Fiserv’s platform, and your statements carry Fiserv’s fee vocabulary. For what those lines mean, see Fiserv fees and Clover fees.

Fee practices: the three-year term

Every fee, explained: see Merchant One fees.

Merchant One does not publish its full pricing. Its advertised rates have carried a qualifier that they apply to qualifying transactions, with full rates and fees in the merchant agreement. That agreement, according to reviewers and complainants, includes:

A three-year initial term, set out in Merchant One’s program guide.
An early termination fee reported as the greater of $295 or $25 for each remaining month, which can reach about $875. Complainants describe cancellation debits of $450, $750 and $900.
Annual fees per location, reported at around $99.
PCI non-compliance fees, including from merchants who say they completed their quarterly scans.
Program and membership-style fees that merchants say they did not know they had agreed to.

Our read. The rate is rarely the problem in these complaints. The term, the exit fee and the small recurring charges are. Those are written into the agreement, so they are enforceable, but enforceable is not the same as explained. See how a merchant can have the lowest rate and the worst deal.

Complaints: a consistent story

Merchant One’s review profile splits sharply. Its Trustpilot average is high. Its Better Business Bureau review average is very low, reported at between about 1 and 2 stars, and its BBB complaints are steady into 2026.

The complaints are remarkably consistent. Merchants describe a sales conversation focused on a low percentage rate, followed later by a three-year contract they say was never mentioned, an early termination fee when they try to leave, and recurring fees they did not recognize. Recent complaints also describe deposits held after cancellation and difficulty getting a full accounting of fees. The company responds to BBB complaints, and some are resolved, but the pattern repeats.

Regulatory and legal: nothing found

We found no Federal Trade Commission or state attorney general actions and no class actions against Merchant One, and independent reviewers report the same. That earns most of the available points. We hold back three because a consistent complaint pattern about undisclosed contract terms is exactly the kind of conduct regulators have pursued against other sales organizations.

Transparency and sales channel

Merchant One’s own marketing has at times advertised no early termination fee and freedom to cancel, while its program guide sets a three-year term. Independent reviewers have flagged that gap repeatedly. Combined with a sales channel that complainants say focused on the rate and left out the term, it costs most of the available points in both categories.

Common questions

Is Merchant One legit?

Yes, in the sense that it is a long-established independent sales organization that resells Fiserv processing, and we found no FTC actions or class actions against it. Its complaint record is poor, though, and most complaints are about contract terms and fees merchants say were never explained.

Does Merchant One have an early termination fee?

Reviewers and complainants report one. Merchant One’s program guide sets a three-year initial term, and early termination fees have been reported as the greater of $295 or $25 for each remaining month, with some merchants describing debits of $450 to $900. Read your own agreement before you cancel.

How do I cancel Merchant One?

Send written notice, as the agreement requires, and keep proof of delivery. Ask in writing for the early termination fee amount, equipment return instructions and a final accounting, and watch your bank account for debits after the cancellation date.

What fees does Merchant One charge?

Merchant One does not publish full pricing; rates and fees depend on your agreement. Merchants have reported annual fees per location, PCI non-compliance fees, membership-style program fees and early termination fees in addition to their processing rate.

Who processes Merchant One accounts?

Merchant One resells Fiserv processing and offers Fiserv’s Clover point-of-sale systems, so your account runs on Fiserv’s platform.

Why does Merchant One have good Trustpilot reviews but poor BBB reviews?

Different platforms collect different reviews. Merchant One’s Trustpilot average is high, while its Better Business Bureau review average is very low and its complaints focus on billing and cancellation. The complaint pattern is the more useful signal for a merchant deciding whether to sign.
