What’s the Purpose of an ISO?

What is an ISO?

An ISO is a third-party company that is authorized by a credit card network (like Visa or Mastercard) to resell merchant services—including credit card processing—on behalf of an acquiring bank. In simpler terms, an ISO helps businesses (such as online ticketing platforms, venues, or event organizers) set up and manage their ability to accept card payments.

Role of an ISO in Online Ticketing:

1. Merchant Account Setup
   ISOs work with acquiring banks to get merchant accounts approved and opened. These are essential for online ticket sellers who need to accept credit or debit card payments.

2. Payment Gateway Integration
   Many ISOs partner with or offer access to payment gateways, helping ticketing platforms integrate secure payment solutions into their websites or apps.

3. Sales and Support
   ISOs often provide customer service, technical support, training, and fraud prevention tools to merchants. They act as a liaison between the business and the acquiring bank or processor.

4. Fee Structuring
   They may negotiate processing rates and terms with the merchant, which can affect the overall cost of accepting payments for ticket sales.

ISO vs. Payment Processor

While an ISO is not the processor itself, it sells and supports the services of one or more processors. For example, an ISO might resell services from First Data (now part of Fiserv), Elavon, or Worldpay, but it doesn’t handle the actual processing or fund transfers.

Why ISOs Matter in Ticketing

Online ticketing platforms often partner with ISOs to:

• Simplify the complex process of accepting credit card payments

• Offer bundled services (payment gateways, fraud tools, PCI compliance support)

• Reach specific industries or niches (like events, sports, or performing arts)

Example:

If you’re launching a ticketing website and want to accept credit card payments, an ISO can help:

• Set up your merchant account

• Connect you to a gateway

• Provide support and tools to manage your transactions

In summary, an ISO is a certified intermediary that connects online ticket sellers with the infrastructure they need to accept and manage credit card payments, offering both sales and support services on behalf of acquiring banks and processors.
