Common Mistakes New ISOs Should Avoid

The merchant cash advance industry continues to attract ambitious individuals looking to build a career in alternative finance. As an Independent Sales Organization (ISO), you play a vital role in connecting small business owners with fast and flexible funding. But while the opportunity is exciting, the early stages of being an ISO come with their own challenges. Knowing what to avoid from the start can help you navigate the MCA space with confidence and professionalism.

Rushing the Learning Curve Can Cost You

Many new ISOs are eager to close deals quickly and start earning commissions. However, entering the market without a clear understanding of how submissions work often leads to mistakes. These include sending incomplete applications, choosing merchants that don’t meet funder guidelines, or misunderstanding how funding timelines actually play out.

A rushed approach also creates communication breakdowns. If you don’t fully understand the deal process, it becomes harder to explain things to the merchant. This leads to confusion, mismatched expectations, or even withdrawn applications. Taking the time to understand underwriting basics, submission requirements, and funder preferences is not just helpful. It is essential.

Instead of focusing solely on volume, focus first on quality. Ask questions, review successful deal structures, and study different funders’ requirements. That foundation will allow you to scale faster and with fewer errors later on.

Avoid These ISO Pitfalls

Whether you’re working independently or with a team, these are the most common mistakes that new ISOs make in the field. They might seem small, but each one can weaken your credibility and cost you deals.

  • Weak submission packages: Missing documents, unclear statements, or lack of merchant background all slow down the process and reduce the chance of approval.
  • Misaligned merchants: Sending deals that don’t fit a funder’s criteria shows a lack of due diligence and wastes time on both sides.
  • Overpromising terms: Telling merchants what they want to hear, instead of what’s realistic, can damage trust and hurt your reputation.
  • Ignoring compliance: Not protecting personal or financial data puts everyone at risk and signals unprofessional behavior.
  • Poor communication: Waiting too long to follow up or failing to respond to merchant or funder questions shows lack of organization.
  • No lead tracking system: Without using a CRM, it’s easy to lose track of submissions, miss follow-ups, and repeat the same mistakes.
  • Chasing every deal: Trying to submit every lead you receive without qualifying them first leads to low approval rates and poor funder relationships.

Building good habits early creates consistency and shows funders that you respect their process. This is something that separates professionals from beginners.

Merchant Fit Matters More Than You Think

One of the fastest ways to build funder trust is by sending merchants that are actually a good fit. New ISOs often make the mistake of trying to submit every lead, regardless of business type, revenue level, or stability. But experienced funders know when a merchant is a poor match. Too many weak deals can lead them to ignore future submissions from you.

To avoid this, learn to qualify merchants upfront. Review their average monthly revenue, number of deposits, time in business, and existing obligations. A 6-month business with consistent $20K+ revenue and no recent defaults is far more likely to be approved than a newer, unpredictable business. When funders see that you’re selective and strategic, they’ll treat your files with more urgency and respect.

Every ISO makes mistakes. That’s part of the learning process. But avoiding the most common ones will save you time, protect your relationships, and increase your approval rate. Focus on preparation, clear communication, and finding strong merchant-funder matches. In this business, your name is your brand. The sooner you establish yourself as reliable and knowledgeable, the faster your success will grow.
