Comprehensive Guide to Merchant Service Providers (MSPs) and ISOs


Merchant service providers, also known as Independent Sales Organizations (ISOs), set up electronic payment processing for businesses. ISOs connect merchants and financial institutions, allowing merchants to accept credit card and debit cards, digital wallets and online payments.

By providing the necessary infrastructure, technology, and expertise, merchant service providers empower businesses to offer convenient payment options to their customers while adhering to industry standards and compliance regulations.

ISOs offer payment technologies and integrations that enhance revenue streams, improve customer satisfaction, and navigate the complexities of electronic payment processing for businesses.

For example, if you are a merchant service provider wanting to implement an omnichannel payment experience for customers, you would provide the expertise and solutions to integrate the business’s point-of-sale (POS) systems with online platforms and mobile payment options. This allows the business to offer a consistent and convenient payment experience across various channels, enabling customers to make purchases in-store, online, or via mobile devices. This integration enhances revenue streams by capturing sales from different channels and improves customer satisfaction by providing flexibility and convenience in the payment process.


Why Become a Merchant Service Provider?

1. Growing Market Demand

With the increasing adoption of e-commerce, mobile payments, and contactless transactions, the digital payment industry is experiencing rapid growth. Businesses need reliable MSPs to facilitate these payment methods. By entering this market, you can tap into a booming industry with an almost limitless customer base.


2. Recurring Revenue Model

MSPs typically earn revenue through transaction fees, monthly service fees, and additional charges for value-added services. This creates a steady stream of recurring income. As businesses continue to process payments, your revenue grows, providing financial stability and growth potential.  MSP revenue for dual price processing is even greater than traditional processing, as there is no interchange fees to the merchant, allowing greater profit margins for both the business owner and MSP.


3. Diverse Client Base

Virtually every business, from small retailers to large enterprises, requires payment processing services. This diverse client base means that MSPs can cater to a wide range of industries, reducing dependency on any single sector and spreading risk.  It also means there are plenty of clients within a particular industry if you prefer to specialize.


4. Technological Advancements

The payment processing industry is at the forefront of technological innovation. As an MSP, you can work with cutting-edge technologies such as blockchain, artificial intelligence, and mobile payment solutions. This keeps the business dynamic and offers opportunities for continuous learning and growth.


5. Flexibility and Independence


Many MSPs operate as independent agents, giving you the freedom to work on your terms. This flexibility allows you to balance your personal and professional life while growing your business at your own pace.




How to Become a Merchant Service Provider

Step 1: Understand the Industry

Before diving into the MSP industry, you must conduct thorough market research. Understand the competitive landscape, identify potential customers, and understand the demand for different payment solutions. Familiarize yourself with key concepts such as payment gateways, merchant accounts, interchange fees, and the roles of various stakeholders (banks, card networks, etc.).  This research will help you carve out a niche and develop a unique value proposition.

2. Choose Your Business Model

Decide whether you want to operate as an independent sales organization (ISO), a payment facilitator, or partner with an existing MSP. Each model has its advantages and requirements, so choose the one that aligns with your goals and resources.  Partnering with an existing experienced MSP is the lowest barrier to entry as they typically have developed resources for partners to start selling quickly.


Step 3: Develop a Business Plan

A comprehensive business plan is crucial for any new venture. You should outline your business goals, target market, marketing strategies, revenue model, and financial projections. This plan will serve as a roadmap for your business and help secure funding if needed.


Step 4: Obtain Necessary Licenses and Certifications

Depending on your location, you may need to obtain specific licenses and certifications to operate as an MSP. Research the regulatory requirements in your region and ensure you comply with all legal obligations. This may include registering your business, obtaining a payment processing license, and adhering to data security standards such as PCI DSS (Payment Card Industry Data Security Standard).  If you are partnering with an existing MSP, bank registration is not required (which averages around $10,000 for the first year and $5,000 for each subsequent year).


Step 5: Choose Your Technology Partners

Select reliable technology partners to provide the necessary infrastructure for payment processing. This includes payment gateways, point-of-sale (POS) systems, and mobile payment solutions. Partnering with established technology providers ensures that you offer secure, efficient, and scalable services to your clients.


6. Develop a Service Offering

Create a comprehensive suite of services to meet the diverse needs of your clients. This offering might include payment processing, point-of-sale systems, mobile payment solutions, e-commerce integration, and fraud prevention tools. 


Step 5: Build a Strong Team

Assemble a team of skilled professionals with expertise in finance, technology, customer service, and sales. A strong team will help you handle the complexities of the payment processing industry and deliver exceptional service to your clients. 


Step 7: Create a Robust Security Framework

Security is paramount in the payment processing industry. Implement robust payment security measures to protect sensitive customer data and prevent credit card payment fraud. This includes encryption, tokenization, and regular security audits. Building a reputation for security and reliability will attract and retain clients.


Step 8: Develop a Marketing Strategy

Promote your card processing services through various marketing channels such as social media, content marketing, email campaigns, and industry events. Highlight your unique value proposition, such as competitive pricing, advanced payment technology, or superior customer support. Building brand awareness and credibility is essential for attracting and retaining clients.


Step 9: Provide Exceptional Customer Support

Offering excellent customer support is crucial in the payment processing industry. Ensure that your clients have access to 24/7 support and quick resolution of any issues. Building strong relationships with your clients will lead to long-term partnerships and positive referrals. Partnering with an MSP in most cases will allow you to use their customer service and technical support departments, reducing your startup costs.



The merchant services industry presents significant opportunities for freedom, revenue, and diverse technical and business ventures, all with relatively low barriers to entry. By gaining a foundational understanding of the industry and diligently following these steps to establish your business, you can provide secure, reliable, and innovative payment solutions, ultimately fostering the growth of a successful MSP for years to come.  For cutting-edge technology, top-tier technical support, and robust customer service, marketing, and sales support, reach out to SignaPay today for your payment solutions.
