Whether you plan to launch a credit card processing company, operate as a payment service provider (PSP), or leverage a white-label payment gateway, this comprehensive business plan framework will help you enter the payment processing market with confidence.

Key Concepts and Definitions

To dominate the payment processing industry, you need to master the game-changing concepts and terminology that define how payment processing companies deliver results. A payment processing company, often called a payment processor, serves as the power-packed intermediary that empowers merchants to seamlessly accept payments from customers—whether through credit card payments, debit card payments, or online payments that drive revenue growth.

Payment processing involves the secure, lightning-fast transfer of funds from the customer’s account straight to the merchant’s account, powered by a robust payment processing system that never sleeps. Payment processors are the unsung heroes ensuring that card payments and digital transactions get authorized, processed, and settled with maximum efficiency. Transaction processing is the core function of handling online payments, encompassing tasks such as authorization, settlement, and reconciliation within a secure, scalable platform. Payment gateways serve as another mission-critical component, delivering the ultra-secure interface that transmits payment information between merchants and payment processors without missing a beat.

In today’s fast-evolving payment processing industry, processing companies must support a comprehensive range of payment methods—including credit cards, debit cards, and digital wallets—to exceed the expectations of both merchants and consumers who demand seamless experiences. By mastering these fundamental concepts, you’ll be perfectly positioned to evaluate cutting-edge payment processing solutions and make winning decisions when launching or scaling your payment processing empire.

What Is a Payment Network?

A payment network is the invisible engine that powers every online transaction—from buying a coffee with a card to sending money through an app. It connects customers, merchants, banks, and financial institutions, ensuring funds move safely and efficiently.

In simple terms, payment networks enable businesses to accept card payments and online payments securely. They ensure the authorization request, settlement, and funds transfer happen smoothly between the customer’s account (as the source of funds) and the merchant’s account.

Key Components of a Payment Processing System

To understand how payment processors work, let’s break down the ecosystem:

Payment Gateway – The digital bridge between a website or point-of-sale and the processor. It encrypts credit card details and sends them securely for authorization.
Payment Processor – The company that routes data between merchants, banks, and card networks (like Visa or Mastercard). It ensures transactions are verified, approved, and settled.
Acquiring Bank – The merchant’s financial institution that receives transaction requests and deposits funds after settlement.
Issuing Bank – The customer’s bank that issues credit or debit cards and authorizes transactions.
Card Network – Systems like Visa, Mastercard, or American Express that govern the rules and infrastructure for global electronic payments.
Merchant Account – A dedicated account enabling businesses to accept online payments and receive funds from card transactions.

These elements work together to process every authorization request, handle interchange fees, and ensure secure payment acceptance for both physical and online payment processing businesses.

Understanding the Payment Processing Business Models

Different types of entities operate in the payment processing industry, each with unique roles and regulatory responsibilities:

Aspect	Payment Processor	Payment Service Provider (PSP)	Payment Facilitator (PayFac)
Definition	Provides core technology infrastructure for transaction authorization and settlement.	Offers merchants multi-method payment processing services and dashboards.	Aggregates sub-merchants under one master merchant account.
Merchant Account	Requires separate account per merchant.	PSP connects merchants to acquirers.	Sub-merchants use PayFac’s account.
Role	The “engine” of the system.	The “interface” for merchants.	The “aggregator” for small merchants.
Examples	FIS, Worldpay, Global Payments.	Stripe, Adyen, Checkout.com.	Square, PayPal Here, Stripe Connect.

An independent sales organization (ISO) is another key player in this space. ISOs are third-party organizations registered with card networks to facilitate online payments for merchants. Unlike PSPs and PayFacs, ISOs typically provide merchants with their own merchant accounts and have more direct control over the payment process, transaction management, and money flow. They often build and maintain their own infrastructure to support these services, distinguishing them from other models.

Choosing between these models depends on your target market, scale, and regulatory requirements. The payment process can be more streamlined or complex depending on whether you use a PayFac, PSP, or ISO, as each model offers different levels of integration and control over transactions.

For instance, a credit card processor serving large enterprises must meet strict compliance standards and invest heavily in technology infrastructure, while a payment facilitator can focus on smaller merchants seeking quick onboarding and low monthly fees. The role of a payment processor involves managing the entire payment processor work cycle, including transaction authorization, verification, and settlement, ensuring secure and efficient movement of funds.

The European Regulatory Landscape

Understanding regulatory compliance is one of the most critical steps in starting a payment processing company. Let’s explore the key jurisdictions in Europe:

1. United Kingdom – Financial Conduct Authority (FCA)

In the UK, the FCA regulates Electronic Money Institutions (EMIs), Payment Institutions (PIs), and Account Information Service Providers (AISPs) under the Payment Services Regulations 2017 (PSRs) and Electronic Money Regulations 2011 (EMRs).

Any business offering payment processing services must register or gain authorization from the FCA, ensuring transparency, customer data protection, and anti-money laundering compliance.

2. Germany – BaFin

Germany’s BaFin oversees companies providing payment operations under the Payment Services Supervision Act (ZAG). Businesses must apply for authorization to handle online transactions, ensuring they maintain robust security systems, transparent pricing, and proper transaction management frameworks.

3. France – AMF and ACPR

France’s AMF and ACPR supervise electronic payments under the Monetary and Financial Code. The regulatory framework emphasizes own funds requirements, outsourcing rules, and cybersecurity measures—especially for companies that accept payments via alternative payment methods or offer value-added services like digital wallets or loyalty systems.

4. Switzerland – FINMA

Switzerland’s FINMA focuses on financial market stability and technology adoption. While its regulations differ from the EU, it requires strong anti-money laundering, fraud detection, and data protection controls for payment providers.

5. Luxembourg – CSSF

The CSSF regulates Payment Institutions (PIs), Electronic Money Institutions (EMIs), and AISPs under the Payment Services Law (PSL). It covers everything from authorization to AML/CFT obligations and ICT risk management, ensuring secure payment operations across the EU.

Industry Requirements for Payment Companies

Operating in the payment processing industry means you’re stepping into a landscape where strict regulatory and operational standards aren’t just guidelines—they’re your pathway to success. Payment processing companies must secure the appropriate licenses and register with relevant authorities before they can legally offer payment processing services, and this isn’t just bureaucracy—it’s your foundation for building trust. This often involves demonstrating compliance with industry standards such as PCI DSS, which is absolutely essential for safeguarding payment card data throughout the payment process and giving your clients the confidence they deserve.

Beyond licensing, processing companies get to implement robust security measures that don’t just protect—they empower sensitive customer information protection and prevent unauthorized access or fraud. This includes advanced encryption, secure data storage, and regular security audits that keep you ahead of the curve. Compliance with anti-money laundering (AML) and know-your-customer (KYC) regulations isn’t just mandatory—it’s your competitive advantage, ensuring that payment processing companies can identify and verify their clients, monitor transactions for suspicious activity, and report any potential risks to authorities with confidence and precision.

By meeting these industry requirements, payment processing companies don’t just protect themselves and their customers—they build a reputation for reliability and trustworthiness that sets them apart in a highly competitive market. Staying ahead of regulatory changes and maintaining best-in-class security practices aren’t just essential—they’re your ticket to long-term success in the payment processing industry, helping you scale faster while delivering the exceptional security and compliance your clients expect.

Key costs include backend development, fraud detection, KYC/AML modules, and integration with payment networks for processing financial transactions.

4. Can I build my own payment gateway?

Yes, you can build your own payment gateway, but it’s a complex project that requires expertise in cybersecurity, data encryption, and PCI DSS compliance. A payment gateway securely transmits payment information between the customer, merchant, and payment processor. Most startups prefer using a white-label payment solution because it’s easier to customize, maintain, and scale without heavy upfront investment.

5. How do credit card payments work?

Credit card payments involve several key steps:

The customer initiates a purchase.
The payment gateway encrypts and transmits the payment information.
The payment processor sends an authorization request to the issuing bank.
The issuing bank checks for sufficient funds or credit.
If approved, the transaction is completed and settled to the merchant’s account.

This entire transaction process takes just a few seconds thanks to modern payment processing software.

6. What are digital payments, and how do they differ from traditional methods?

Digital payments are electronic transactions made through online platforms, mobile wallets, or apps rather than cash or checks. They include credit and debit cards, digital wallets (like Apple Pay or Google Pay), and bank transfers. Compared to traditional methods, digital payments are faster, more secure, and easier to track, providing businesses with better visibility and automation for financial transactions.

7. What is payment processing software?

Payment processing software is the core technology that enables merchants to accept card payments, verify transactions, and manage settlements. It connects with payment gateways, banks, and card networks to ensure smooth, secure payment transactions. A robust solution should offer recurring payments, fraud prevention, detailed analytics, and seamless API integrations for businesses of all sizes.

8. What are payment processing solutions?

Payment processing solutions refer to the complete set of tools and services that help merchants manage online transactions—including authorization, settlement, and chargeback management. These can be built in-house or provided by payment providers such as Stripe, Adyen, or Worldpay. A well-designed payment solution should support multiple payment methods, recurring billing, and global currencies.

9. What does a payment processor send during a transaction?

During a transaction, a payment processor sends an authorization request containing the cardholder’s payment information to the issuing bank. The bank then verifies the card’s validity and sufficient funds before sending an approval or decline message back. The processor then handles settlement and reporting, ensuring funds move correctly between accounts.

This secure communication is at the heart of every credit and debit card transaction.

10. What are recurring payments and why are they important?

Recurring payments are automatic charges that occur on a set schedule—common in subscriptions or memberships. They simplify financial transactions for both businesses and customers, ensuring predictable revenue and convenience. Modern payment processing software automates recurring billing, manages invoices, and prevents failed charges, making it an essential feature for any modern payment processing business.
