The Payments Company Hiding in Plain Sight

Most people will never knowingly use Bottomline. There is no app to download, no glossy checkout button, no ad before a podcast. And yet if you work at a large American company, there is a good chance the money that pays your suppliers - or pays you - passes through software built by a firm headquartered in Portsmouth, New Hampshire. Bottomline is the kind of business that operates one layer beneath the visible economy: the plumbing, not the faucet.

That was more or less the point from the start. In 1989 a former IBM engineer named Daniel McGurl decided that businesses did not actually need pre-cut paper checks and the whole clumsy ritual around them. He and co-founder Jim Loomis set up shop in Exeter, New Hampshire, to automate the way companies paid their bills. It was an unglamorous bet on an unglamorous problem, and it turned out to be a durable one. Thirty-seven years later, checks are still a big chunk of how American businesses pay each other - which means Bottomline still has plenty of work to do.

McGurl and Loomis ran the company with the patience of people who expected to be around a while. McGurl served as chief executive for roughly its first thirteen years and stayed on as chairman until 2007; Loomis, who came from Nashua Corp, shaped the early product strategy and culture before retiring in 2000. Both founders remained on the board until 2016. It is a founding story with almost no drama in it - two people who found a boring problem, decided it was worth decades, and were right.

What Bottomline actually does

Strip away the product names and Bottomline does one thing: it moves business money and tries to keep it safe on the way. In practice that splits into a few connected lines of work. There is payments automation - software that takes an invoice and turns it into a paid supplier without a human keying in bank details. There is Paymode, a network where buyers and suppliers meet to send and receive digital payments. There is a digital banking platform that banks license and put their own name on. There is a stack of financial messaging and connectivity tools that speak the languages of global finance - SWIFT, SEPA, Bacs, Faster Payments. And wrapped around all of it is a growing fraud and compliance layer.

Who pays for it

Bottomline's cleverest structural choice is that it sells to both sides of the same table. On one side are corporations - the accounts-payable and treasury teams who need to pay thousands of suppliers, chase receivables, and see their cash across a dozen currencies. On the other side are banks and financial institutions, who license Bottomline's technology and hand it to their own corporate customers under their own logo. The two audiences reinforce each other: the more corporates on the network, the more useful the network is to a bank, and vice versa.

The reach is wide. The company says roughly a million businesses use its platforms, and cites an estimated 90% of the Fortune 100 among its customers. Its Paymode network alone counts more than 600,000 businesses exchanging over $500 billion a year. Those are the numbers of infrastructure, not of a product.

The problem it keeps solving

The stubborn fact underneath Bottomline's business is that paying other businesses is still hard. Consumer payments got fast and frictionless years ago; business payments did not. Invoices arrive as PDFs and paper. Bank details get retyped and mistyped. A meaningful share of US B2B payments still moves by paper check - slow, expensive, and, crucially, the format fraudsters love most. Every one of those frictions is a line item Bottomline sells against.

Fraud is the emotional core of the sales conversation. Every finance chief has heard the story - a convincing email, a changed bank account, a wire that vanishes. Bottomline turned that fear into a product line. In early 2026 it launched Payments Fraud Defense, an AI-driven, multi-layered system that watches payments in real time, and it built the network so that on Paymode, the company says, fraud is effectively near-zero. Selling sleep to people who lie awake about wire fraud turns out to be good business.

The expertise underneath

There is a reason banks are willing to license Bottomline rather than build their own. Moving money between institutions means speaking a set of exacting, unforgiving dialects - SWIFT, ISO 20022, SEPA, Bacs, CHAPS, Faster Payments - where a malformed message is a failed payment. Bottomline has spent decades in that grammar, which is how it landed among the top three SWIFT service providers in the world. That connectivity expertise is not flashy, but it is the sort of capability that takes years to build and moments to trust, and it anchors much of the rest of the business. Around it sits a leadership team the company describes as carrying more than 150 years of combined experience across payments, banking and software.

The customer base reflects that credibility. Bottomline serves more than 10,000 corporations, banks and financial institutions, and its digital banking platform is used by hundreds of thousands of corporates originating trillions of dollars in payments a year. When a company sells to both the treasurer writing the payment and the bank clearing it, the relationships tend to be long and the switching costs high. Software you can rip out in a quarter is a feature; software wired into how a bank moves money is infrastructure.

How it makes money

Bottomline runs the model private-equity owners like: recurring software revenue blended with per-transaction payments revenue. Corporations pay subscriptions for automation and cash-management software. Banks pay to license the digital banking and connectivity stack. And the Paymode network throws off transaction and monetization revenue that scales with volume rather than headcount. It is a business that gets more valuable, not just larger, as more money flows across it.

The ambition under current leadership is blunt: build a "B2B payments behemoth" by wiring banks, corporates and suppliers onto one secure rail.

Where it sits in the market

Bottomline occupies an unusual middle. In B2B payments and AP/AR it bumps against names like BILL, Coupa, Stripe and PayPal. In digital and core banking technology it competes with Temenos, Finastra, ACI Worldwide and NCR Voyix. In payment fraud and verification it lines up against specialists like Form3 and SurePay. Few rivals span all three lanes at once. That breadth is the moat and the complexity - each product makes the others stickier, but it also makes Bottomline harder to explain in a sentence.

A long, quiet compounding

Bottomline's history reads less like a rocket and more like a freight train. It went public on NASDAQ in 1999 at $19 a share under the fitting ticker EPAY. Over the next two decades it made around eleven acquisitions across six countries, stitching payments and banking capabilities together. In December 2021 the software-focused private-equity firm Thoma Bravo agreed to buy it; the roughly $2.6 billion, all-cash deal closed in May 2022 at $57 a share, and EPAY left the public markets. Under CEO Craig Saks - a payments veteran who previously ran parts of ACI Worldwide - the company kept moving, buying Nexus Systems, selling off its Legal Spend Management division to Sedgwick in 2025 to concentrate on core payments, and, in mid-2026, wiring American Express's Buyer Initiated Payments into Paymode.

There is something quietly instructive about a global payments company that runs from a four-story building in New Hampshire rather than a glass tower on a coast. Bottomline never needed to be the name on the app. It needed to be the thing the app connects to - the rail underneath the money. That is a harder position to reach and a much harder one to dislodge.
