If you oversee a business that accepts credit or debit cards, you’ve probably heard of an independent sales organisation (ISO). But what does it actually mean, and why should you collaborate with one?

Whether you’re starting a business or working in a high-risk industry, collaborating with an ISO can be essential. From accelerated approval to personalised support, the benefits are hard to ignore.

In this post, we’ll go over what an ISO does, how it can help you find the best merchant account, and why this partnership might be the best payment setup decision you’ve ever made.

What Is an Independent Sales Organization (ISO) and How It Helps with Your Merchant Account?

Let’s start with the basics. An independent sales organisation, or ISO, is a third-party company that connects businesses with acquiring banks. If you want to accept credit or debit cards, they help you set up and manage your merchant account.

Despite not being banks, major card networks such as Visa and Mastercard have certified ISOs. This allows them to work closely with merchant account providers to help you with the application process.

Better yet, a lot of ISOs focus on processing payments for high-risk companies. Therefore, an ISO can open doors if you work in a field where traditional banks might say no, like gambling, cryptocurrency, adult content, or forex. High-risk card payments are covered in more detail here.

Why You Need a Merchant Account to Accept Card Payments

In short, the money you pay with your card is stored in a merchant account until it is transferred to the bank account of your business. If you want to accept payments with a credit or debit card, you need to have one. If you don’t have it, you’re missing out on a lot of potential customers.

An aggregated account is a one-size-fits-all solution offered by certain payment service providers. It’s not the best choice if you’re growing or operating in a high-risk industry, but it might work for small or low-risk businesses. A dedicated merchant account offers enhanced fraud protection, more control, and comprehensive reporting.

An ISO’s worth is demonstrated here. They can match you with the best merchant account provider by learning about your business model and risk tolerance. See our comprehensive guide on high-risk merchant account approval if you have any questions about the approval process.

How ISOs Support Underwriting and the Merchant Onboarding Process

Underwriting is where things can get complicated. Banks evaluate your risk before granting you a merchant account using this procedure. They will examine your industry, your financial history, and your processing capacity. See our merchant category code guide for a more thorough explanation of risk factors.

Underwriting is frequently the most difficult aspect for high-risk companies. ISOs can help with that. They understand how to create a strong application and what underwriters are looking for. They will assist you in gathering the appropriate paperwork, outlining your business plan, and avoiding any red flags.

This leads to a faster and more seamless merchant onboarding process. Your ISO takes care of the specifics, so you don’t have to guess what’s required.

Free, fast, no strings attached.

Key Benefits of Partnering with an ISO for Your Merchant Account

Let’s look at why working with an ISO is a smart decision:

1. Access to Multiple Merchant Account Providers

Traditional banks can be rigid. You’re out of luck if one says no. However, a network of merchant account providers collaborates with ISOs. This increases your chances of approval, particularly if your company is classified as high-risk.

2. Faster Underwriting and Approval

ISOs are skilled at submitting applications that yield results because of their underwriting experience. They make sure everything is in order and steer clear of common blunders, which can drastically cut down on wait times.

3. Specialist Support for High-Risk Merchant Accounts

High-risk industries face extra hurdles. Fortunately, ISOs like CardCorp specialise in high-risk merchant accounts. We understand your challenges and know how to present your case to the right merchant account provider.

4. Lower Fees and Better Payment Terms

ISOs can often negotiate better deals. They understand the pricing structures of payment service providers and can help you avoid hidden fees. That means more savings and fewer surprises. Also, we can help you spot the red flags in your current payment provider.

5. Tailored Payment Gateway and Processing Solutions

Every business is different. Whether you need recurring billing, a custom payment gateway, or multi-currency support, an ISO can help you set up a payment processing system that fits your exact needs. If you’re new to gateways, read our complete payment gateway guide.

6. Dedicated Account Management and Ongoing Support

Your journey doesn’t end once you’re approved. A good ISO offers ongoing help – managing disputes, tackling chargebacks, and ensuring compliance. In other words, they’re a long-term partner, not just a middleman.

Choosing the Right ISO and Merchant Account Provider

Of course, not all ISOs are created equal. Here’s what to look for when choosing one:

  • Industry experience – especially if you need a high-risk merchant account
  • Clear, transparent pricing
  • Strong ties with reliable payment service providers
  • Proven track record
  • Hands-on support throughout the process

Credit Card Processing and Payment Gateway Support from ISOs

These days, processing credit cards is essential, whether you’re doing business online, in-person, or both. You can access tools that are dependable, secure, and customized to your business model by partnering with an ISO.

Do you have to combat fraud? Take payments from overseas? Monitor transactions in real time? Everything is possible with a good ISO. Use our guide to credit card processing to learn the fundamentals.

Ideal Payment Processing for High-Risk Businesses and Scaling Startups

ISOs are very helpful in this situation. We find a merchant account provider who can grow with you as you progress from one stage to the next.
