At Fairmount Payments, we are aware that the payments industry is primarily driven by agents and Independent Sales Organizations (ISOs).

Finding the right partner is crucial to long-term success, regardless of your level of experience as an ISO with a developing portfolio or as a new agent trying to establish yourself in the marketplace.

What an ISO Agent is and how they fit into the larger payments ecosystem is one of the most frequent queries we get.

We break it down in this guide, covering everything from roles and responsibilities to how ISO Agents can develop a successful business with the right assistance.

What is an ISO Agent?

An ISO Agent, which stands for Independent Sales Organization Agent, is a business entity or independent contractor that collaborates with a registered ISO or payment processor to offer merchant services to companies, including e-commerce payment gateways, point-of-sale (POS) systems, and credit card processing.

Think of ISO Agents as the front-line salespeople of the payments industry.

They connect with merchants, understand their needs, and provide tailored payment solutions while operating under Fairmount Payments’ infrastructure and support.

What Do ISO Agents Do?

ISO agents combine sales, customer support, and payment consulting in their many roles. Usually, their primary duties consist of:

  • Identifying and prospecting new business clients
  • Educating merchants on available payment technologies
  • Assisting with the merchant onboarding process
  • Acting as a liaison between the merchant and the processor
  • Providing ongoing service and support after onboarding
  • Building a book of business that generates residual income

At Fairmount Payments, we give our agents the resources, instruction, and technology they need to accomplish all of the above while maintaining their independence.

Why Merchants Work with ISO Agents

Working with an ISO Agent instead of a big processor or bank directly gives business owners a more individualized and flexible experience. ISO Agents frequently offer:

  • Customized pricing structures
  • Hands-on support and faster responses
  • Local or industry-specific expertise
  • Access to a wider range of terminals, POS systems, and software

Specifically for small and mid-sized enterprises searching for trustworthy partners, that human touch makes a significant difference.

Pros and Cons of Being an ISO Agent

Pros

  • Low initial expenses, in contrast to registering as an ISO
  • Potential for recurring income
  • Work from anywhere and have a flexible schedule
  • A chance to establish enduring relationships with clients

Cons

  • Learning curve for compliance and payments
  • In certain markets, there is high competition.
  • Income does not come in right away because residuals take time to accumulate.
  • To prospect and close deals, one needs to be self-motivated.

The Future of ISO Agents in a Digital World

The role of the ISO Agent is changing with the payments industry.

Businesses now have higher expectations for their payment providers due to the growth of contactless payments, mobile wallets, AI fraud detection, and integrated commerce platforms.

Agents who embrace innovation, provide value-added services, and maintain their education will succeed.

To help our team stay ahead of the curve, Fairmount consistently makes investments in new technology, alliances, and agent training.
