A restaurant teaches its owner things that rarely appear in a business textbook. There are margins to protect, employees to manage, vendors to pay, customers to satisfy, and above all, cash flow to keep moving. For Allen Kopelman, Founder & CEO of Nationwide Payment Systems, those lessons became the foundation for a career that would eventually take him into the payments industry.
Before entering fintech, he worked as a chef, executive chef, and restaurant owner. Running a restaurant put him close to the daily realities of business, including how quickly a small problem with cash flow can affect everything else. When he entered the payments industry in 1998, he began looking at those same pressures from the other side of the transaction.
He noticed that businesses accepted payments every day, yet many had little understanding of the infrastructure and economics behind them. That gap shaped the way he approached the industry. His philosophy is straightforward: payments should not sit on the side of a business. They should help the business run better.
From Merchant Services to Payment Infrastructure
When Nationwide Payment Systems was founded in 2001, the payments industry was built around a fairly simple proposition: provide businesses with the equipment and rates needed to accept transactions. But Allen saw a wider problem. Business owners did not simply need another terminal or a better rate. They needed someone who understood how payments fit into the way their businesses actually worked.
That idea became the starting point for NPS. The company set out to offer more than payment processing, combining technology recommendations, operational guidance, and ongoing support. The relationship did not end when an account was opened.
Over time, that approach pushed NPS beyond the traditional merchant-services model. Today, the company increasingly sees its role as helping businesses design payment infrastructure that works alongside accounting, software, cash flow, customer experience, fraud prevention, and business intelligence. Payments have become intertwined with the systems that keep a company running.
Relationships Built Beyond the Sale
In payments, a problem rarely arrives at a convenient time. A failed transaction can interrupt a sale, delay a payment, or leave a business owner searching for answers when they need them most. That is why accessibility has remained central to Allen’s approach to leadership.
Clients, he believes, should not have to disappear into a ticketing system when something goes wrong. “They want somebody who understands their business and can help solve the problem,” he says. That same thinking shapes how NPS approaches technology and pricing. If a particular processor, solution, or pricing model is not right for a client, the company is willing to say so, even when another answer might lead to a faster sale.
After more than two decades in the industry, that philosophy has become a business principle. “You don’t build a 25-year company by winning every sale. You build it by creating relationships people don’t want to leave.” For NPS, long-term value has always mattered more than a single transaction.
Starting With the Business, Not the Product
The starting point at Nationwide Payment Systems is not a payment product. It is the business itself. Before recommending a solution, the team looks at how money moves through the company, from the moment a customer is billed to the point where the payment reaches the books.
That means asking practical questions. How does the company invoice? Which accounting system does it use? Are customers paying by card, ACH, mobile wallet, or recurring payment? Is the business B2B or B2C? Are inefficient interchange qualifications eating into margins? Does it need an API, or are its payments disconnected from its software?
The answers shape the infrastructure. NPS can bring together card processing, ACH, e-commerce, point-of-sale technology, gateways, recurring billing, payment links, fraud tools, QuickBooks Online, Xero, Sage Intacct, APIs and webhooks, Level 2 and Level 3 processing, and automated invoicing.
Its NPSONE platform reflects where Allen sees the industry going: toward connected payment infrastructure that brings card processing, ACH, invoicing, accounting integrations, APIs, automation and reporting together in one environment. The goal is to reduce the friction between billing a customer, collecting the payment, and reconciling the transaction, without forcing businesses to piece together multiple disconnected payment systems.
The Rate Is Not the Whole Cost
Payment processing can look simple on paper. A business sees a rate, compares it with another offer, and assumes the lower number is the better deal. But the rate tells only part of the story. The real cost can also include markups, downgrades, incorrect interchange qualification, unnecessary fees, and transaction data that is not being used efficiently.
That distinction becomes harder to ignore as payment volume grows. A small inefficiency on individual transactions can become a meaningful expense when multiplied across thousands of payments.
For that reason, Allen encourages business owners to look at their payment statements with the same attention they give other operating costs. “A payment statement should be treated almost like an expense category that deserves ongoing analysis,” he says, rather than something that gets put in a drawer every month.
The focus, therefore, is on the total economics of accepting a payment rather than a headline rate alone.
Making Payment Costs More Transparent
Interchange Pass-Through pricing separates the underlying card costs from the processor’s markup, giving businesses a clearer view of what they are actually paying.
For qualifying B2B transactions, Level 2 and Level 3 data can also help transactions qualify for more favorable commercial-card interchange categories when the appropriate enhanced transaction information is transmitted. Debit savings can similarly have a meaningful impact, particularly for companies processing significant B2C volume. These optimization strategies become especially important for higher-volume and large-ticket businesses, where even small improvements in transaction economics can translate into substantial bottom-line savings.
Payment routing has also become a major topic in the industry. Allen sees value in specific use cases but does not consider it a universal solution. The broader shift, in his view, is toward treating payment optimization as a technology consideration rather than simply a rate-negotiation exercise.
Building for What Comes Next
A payment system that works today can become a limitation tomorrow. For Allen, building a system means thinking beyond the immediate problem and leaving room for what a business may need as it grows.
A company might begin with basic payment acceptance and later add ACH, automated invoicing, subscriptions, tokenization, ERP or accounting integrations, APIs, enhanced reporting or more sophisticated fraud controls. The infrastructure should accommodate those changes without forcing the business to replace everything underneath.
That thinking points toward what he sees as the future of payments: open, connected ecosystems where different technologies can work together. Businesses should be able to enter new channels and adopt new capabilities without rebuilding their entire payment environment.
Leading Through Uncertainty
Since founding Nationwide Payment Systems in 2001, Allen has led the company through recessions, COVID-19, major technology shifts, new regulations, changing card-brand requirements, bank and processor changes, cybersecurity concerns and rapidly evolving customer expectations.
Those experiences have shaped how he approaches leadership when the path ahead is unclear. The process is straightforward: gather the available information, communicate with the people affected, make the best decision possible and keep moving.
“The lesson I’ve taken from those experiences is that leadership during uncertainty is largely about remaining adaptable,” he says.
Entrepreneurs can become attached to the way their businesses once worked. But markets, technologies and customer expectations continue to change, making adaptability a practical necessity rather than simply a leadership ideal.
Measuring What Actually Matters
Nationwide Payment Systems supports businesses across the United States, from growing SMBs to organizations with significant monthly transaction volume. Its clients span B2B, retail, hospitality, e-commerce, SaaS, healthcare and other specialized industries.
That range also makes transaction volume an incomplete measure of performance. Allen looks at client retention, measurable cost reduction, payment efficiency and uptime, along with the ability to solve complex situations.
These measures provide a broader picture of whether NPS is delivering meaningful value to the businesses it serves. Growth matters, but so does the ability to reduce friction, control costs and remain dependable when payment challenges become complicated.
The Achievement of Staying Relevant
Remaining independent and relevant for 25 years is something Allen is particularly proud of. In an industry that has consolidated dramatically, maintaining that independence while continuing to serve changing business needs represents a significant milestone.
The company has expanded from traditional card processing into payment gateways, B2B optimization, SaaS and e-commerce integrations, smart invoicing, APIs, payment automation, consulting and complex payment environments.
For him, that breadth reflects the importance of responding to changing customer needs rather than remaining confined to the company’s original offering. The achievement is not simply longevity, but the ability to remain useful as the payments landscape changes.
Looking Beyond the Technology
B2B Vault: The Biz-to-Biz Podcast has given Allen the opportunity to speak with founders, fintech executives, AI innovators, and entrepreneurs who are seeing different pieces of where business is going. Those conversations have reinforced a simple lesson: innovation can move incredibly fast, but successful technology still needs to solve practical problems.
Does it save time? Does it reduce friction? Does it improve cash flow? Does it reduce cost? Does it make the customer experience better? Those questions, he believes, matter more than the buzzword attached to the technology.
“Technology becomes valuable when people stop talking about the technology and start talking about what it enabled them to accomplish.”
That perspective offers a useful way to view the next generation of payment technology. New tools will continue to emerge, but their lasting value will depend on the business outcomes they produce.
Staying Curious
Curiosity has been a constant throughout Allen’s entrepreneurial journey. Despite decades in the payments industry, he remains deeply interested in what is happening next.
He spends time exploring new technology, speaking with founders, following what fintech and AI companies are building, and considering how those ideas could solve practical problems for clients. That mindset also shapes the advice he gives other entrepreneurs. Experience can provide valuable perspective, but it can also create an attachment to familiar ways of doing things.
“Don’t become an expert in the way things used to work. Become a student of what is coming next.”
For him, staying curious means remaining willing to question established assumptions and learn from what the market is becoming.
The Invoice Is Ready for a Rewrite
The next several years of fintech will be shaped by technologies that make payments more connected to the broader financial workflow. Allen sees AI, embedded payments, intelligent invoicing, account-to-account payments, automated reconciliation, enhanced fraud prevention, and real-time financial data becoming increasingly important.
He sees a particular opportunity in B2B invoicing. That vision is reflected in NPSONE Smart Invoicing, which points toward a more connected and intelligent invoice experience. Sending a PDF and waiting 30 or 60 days for payment feels increasingly out of step with what technology can now enable. “The invoice of the future will be interactive,” he says, bringing card, ACH and digital-wallet options, automated reminders, financing when appropriate, accounting synchronization and intelligent follow-up into a single experience.
AI could eventually sit across much of that workflow, identifying payment behavior, detecting unusual transactions, helping manage risk, optimizing costs and predicting which invoices require attention. The result could be a change in how companies bill, collect and manage cash, turning the invoice from a static document into a more intelligent part of the payment process.
