A 2007-vintage Utah merchant services provider that spent years as one of the better-regarded small-business ISOs, rebranded to pmtbox, raised $15 million in 2026, and repositioned around enterprise e-commerce. The track record is real; the offering a small merchant would be buying today is much less clear than it was.

Tell them what you need. This goes to pmtbox (formerly National Processing) only.
Mid-market and enterprise e-commerce brands wanting payments, fraud scoring and chargeback management from one vendor under a single fee, and willing to negotiate pricing.
As National Processing this was a well-regarded interchange-plus ISO for small US businesses, with an A+ BBB rating held since 2008 and a rate-lock policy that made it a genuine alternative to flat-rate processors. That company still exists — same founder, same Orem address — but it now trades as pmtbox, sells an enterprise e-commerce payments platform, publishes no pricing, and its old website no longer resolves. If you are an enterprise brand, this is a credible and newly funded option. If you are a small merchant looking for the National Processing everyone recommended, confirm that offering still exists before you plan around it.
Are a small or single-location merchant who needs published pricing to compare, or you require certainty about a product line that is visibly in transition.
The headline take, the audiences it's right (and wrong) for, and the genuine differentiators behind the verdict.
A 2007-vintage Utah merchant services provider that spent years as one of the better-regarded small-business ISOs, rebranded to pmtbox, raised $15 million in 2026, and repositioned around enterprise e-commerce. The track record is real; the offering a small merchant would be buying today is much less clear than it was.
A long, clean BBB record from its ISO years combined with fresh venture funding — reported as Utah's largest seed round in a decade — pointed at a completely different market than the one that built the reputation.
Real-world cost at three volumes, plus the rates, fees, payouts, and contract terms that drive them.
This is an awkward listing to write, because the provider being reviewed is not quite the provider that earned the reputation. For most of its life this was National Processing, LLC of Orem, Utah — a small, well-regarded ISO selling interchange-plus pricing to US small businesses, and a regular presence on 'best merchant services' lists precisely because it was not a flat-rate aggregator.
That company still exists. The BBB record shows the business started on 1 October 2007, incorporated ten days later, and has been BBB-accredited since 16 October 2008 with an A+ rating, listing Wayne Hamilton as president. But it now trades as pmtbox, its website entity is Payment Box Inc., the nationalprocessing.com domain no longer resolves, and the new site sells an enterprise e-commerce payments platform. Third-party reporting dates the rebrand to November 2025; we could not confirm that from the company.
The BBB file is the strongest evidence in this review, and it is good. A+ rating, accredited for nearly eighteen years, ten complaints across three years and none closed in the last twelve months. For a merchant services company — a category that generates complaints the way airlines generate delays — that is a light record and it was earned over a long period.
Set against it is a Trustpilot score of 1.9 out of 5 across 69 reviews, still filed under National Processing LLC because no profile exists under the new name. The profile is claimed, so the company is aware of it. The recurring themes are specific and consistent: support that cannot be reached, merchants waiting months for copies of their own statements, and billing continuing after an account was cancelled.
These two records are not actually in conflict, and it is worth understanding why. A BBB letter grade is largely a measure of whether formal complaints get a response, and this company answers them. Trustpilot captures the ordinary experience of merchants who never file anything formal. Both are true: escalate loudly and you will be handled; try to get a statement through normal support and reviewers say you may wait.
On 30 April 2026 pmtbox announced $15 million in seed funding, led by Tandem Ventures with participation from Element Ventures, Cynosure Investment Partners and Pluralsight founder Aaron Skonnard. The release described it as the largest reported seed round in Utah in the last decade, put the customer base at approximately 1,300, and added Tandem founding partner Alex Bean and Finicity founder Nick Thomas to the board. Wayne Hamilton is named as CEO and co-founder.
The stated plan is to expand engineering, risk and enterprise teams and to go to market in 'high-complexity commerce verticals'. The website matches that: it pitches unified payment operations, machine-learning fraud scoring that reduces false declines, and chargeback management under a single fee, and states that pmtbox guarantees the transactions it approves. That last claim is commercially interesting and unusual — if pmtbox absorbs fraud losses on transactions it approved, it is taking risk most processors push back onto the merchant. Get the guarantee and its exclusions in writing before you value it.
Nothing is published. There is no pricing page on pmtbox.com, and the old National Processing rate card — interchange-plus with monthly plans widely reported as starting around $10 for small retail and restaurant merchants and reaching $199 for larger accounts, with rates locked for the life of the account — came from third-party review sites whose source has now gone offline with the domain.
We are not going to restate those figures as current. They may well still be honoured for existing merchants, and they may still be sold. But a rate card that can only be sourced to review articles about a brand that no longer exists is not something to plan a business around. Ask for a written quote, and ask specifically whether the rate-lock policy survived the rebrand.
For a mid-market or enterprise e-commerce brand, pmtbox is a reasonable name to put on a shortlist. It has a real operating history, a clean formal complaint record, a dedicated merchant account through Commercial Bank of California or Chesapeake Bank rather than an aggregated payfac arrangement, fresh capital, and a bundled fraud and chargeback proposition that would otherwise mean a second vendor. At around 1,300 customers it is small, which cuts both ways — less institutional weight, more attention per account.
For a small merchant who came here because someone recommended National Processing, the honest advice is to check before you invest any time. Everything the company now publishes is aimed at a different and much larger customer. The small-business products have not been announced as discontinued, but they are visibly not the priority, and a provider mid-pivot is the wrong place to be a legacy customer on a legacy plan. Call, ask what is still sold, and get the answer in writing.
Products, integrations, payment-type coverage, security posture, and how their support holds up in practice.
Credit and debit card acceptance across online, in-store and mobile channels through a single platform. pmtbox is registered as an ISO/MSP of Commercial Bank of California and Chesapeake Bank.
Bank-to-bank collection alongside card acceptance, a longstanding part of the National Processing offering.
Machine-learning fraud scoring and chargeback handling bundled into the platform fee. pmtbox states it guarantees transactions it approves, covering losses on approved transactions that turn out to be fraudulent — a claim worth getting in writing, with its exclusions, before relying on it.
In-person and card-not-present acceptance, including POS systems and a virtual terminal, carried over from the National Processing product line.

Checked 23 August 2026, on the National Processing LLC profile — the company has not established one under the pmtbox name. The profile is claimed. Complaints concentrate on unreachable support, difficulty obtaining statements, and billing continuing after cancellation.
It appears to be the same business under a new brand. The evidence lines up: the pmtbox website lists 898 N 1200 W, Orem, Utah — the same address the BBB records for National Processing, LLC — and Wayne Hamilton, National Processing's president on the BBB profile, is named as pmtbox's CEO and co-founder in its 2026 funding announcement. The website entity is given as Payment Box Inc. and the BBB profile is still filed under National Processing, LLC, so the legal structure behind the rebrand is not fully public. Third-party reporting places the name change in November 2025; we could not corroborate that date from the company itself.
