Before you can submit a single deal as an MCA broker, you need ISO (Independent Sales Organization) approval from the funders in your network. ISO approval is the lender's version of onboarding — they verify your business, sign legal agreements, and set you up to submit and receive commissions on funded deals.

The ISO approval process is straightforward but varies by funder. Here's exactly how it works and how to build a network of 10–15 approved lender relationships in your first 60 days.

What ISO Approval Means

An ISO (Independent Sales Organization) is an approved third-party that sources and submits deals to an MCA funder. As an ISO, you agree to the funder's submission guidelines, disclosure requirements, and commission structure. In exchange, the funder agrees to underwrite and fund the deals you submit, pay you commission on funded deals, and provide portal access to check submission status.

What Funders Require for ISO Approval

  • Formed business entity — an LLC or corporation (sole proprietorships are sometimes accepted but LLC is preferred)
  • EIN (Employer Identification Number) — required for tax purposes on commission payments
  • Business bank account — commissions are paid via ACH; a business account is required
  • Signed ISO agreement — each funder has their own ISO agreement covering exclusivity, commission splits, and deal requirements
  • Principal information — name, SSN, and sometimes a personal credit check for the business owner(s)
  • State business registration confirmation — proof your LLC or corporation is in good standing

Types of Funders to Build Relationships With

Direct Funders (Tier 1)

Direct funders use their own capital to fund deals. Commission is paid directly from the funder to you, which means the highest payout rates. Examples include large MCA companies that have been in the market for years and have built direct ISO programs. Getting direct funder approvals should be the priority for your most-used lender relationships.

Syndicators and Marketplaces (Tier 2)

Syndicators accept submissions from ISOs and route them to a network of underlying funders. One ISO agreement with a syndicator gives you access to 10–20 funders simultaneously. Lower commission rates than direct but broader coverage. Good for new brokers building their book before they have enough volume to get direct relationships with all major funders.

Specialty and Niche Funders

Some funders specialize in specific industries (trucking, healthcare, construction), deal sizes (micro-deals under $10K or large deals over $250K), or credit profiles (A-paper only or B/C-paper specialists). These relationships are valuable when you specialize in a vertical.

Building a Balanced Lender Portfolio

The goal in your first 90 days is to get approved with 8–15 funders that collectively cover:

  • A-paper funders (600+ FICO, best rates, lower approval rates)
  • B-paper funders (550–600 FICO, moderate rates)
  • C-paper funders (500–550 FICO, higher rates, high approval rates)
  • High-volume funders for deals over $100,000
  • Small deal funders for deals under $25,000
  • Industry specialists aligned with your target verticals

How to Submit Your First Deal Successfully

Once approved, your first submission is a test of your preparation. Funders track ISO performance — approval rate, document quality, and merchant professionalism all affect your relationship. A clean first submission sets the tone.

  • Submit complete packages — missing documents cause delays and reflect poorly on the ISO
  • Know the minimum criteria before submitting — don't waste a funder's time on a deal that clearly doesn't qualify
  • Use the correct portal and format — each funder has preferred submission formats
  • Follow up professionally — check status through the portal rather than calling every few hours
  • Build rapport with your account manager — a strong relationship gets your deals prioritized in underwriting
JYNI's lender matrix helps brokers track their approved funders, their minimum criteria, and which product each funder specializes in — so you always know exactly which lenders to submit to for each deal. No more guessing or submitting to the wrong funder.

Maintaining Strong Funder Relationships

Funder relationships are assets that appreciate over time. Funders remember ISOs who submit clean deals, communicate honestly about their merchant's profile, and refer good volume consistently. These ISOs get faster turnaround, more aggressive approvals on borderline deals, and better commission structures over time.

Funders also remember ISOs who waste their time with bad submissions. A high decline rate damages your relationship and can result in less favorable terms or being dropped entirely. Quality over quantity is always the right approach with funder submissions.

Bottom Line

ISO approval is the foundational step in commercial lending brokering. Get your entity formed, prepare your documents, and systematically build approvals with 8–15 funders covering all credit tiers and deal sizes. Your lender network is your most valuable business asset — build it deliberately from day one.
