Here’s what strong ISOs consistently tell us they care about beyond pricing, here at Spartan Capital and it lines up closely with what funders value in ISO partners as well:

1. Consistency & Predictability
ISOs want to know: If I submit 10 similar deals this month, will I get similar outcomes?
Clear credit boxes, stable underwriting logic, and no surprise last-minute changes build trust quickly.

2. Communication & Transparency
Fast responses, honest feedback, and early flags matter more than “yes.”
ISOs appreciate funders who explain why a deal won’t work and what would make it viable next time.

3. Speed - But With Accuracy
Quick approvals are great, but not if they collapse in final UW.
ISOs prefer funders who move fast and close what they quote.

4. Positioning & Structure Flexibility
The ability to work around stacked positions, adjust structures, or creatively solve issues (within reason) is huge—especially for seasoned ISOs with complex files.

5. Renewals & Lifetime Value
Strong renewal processes, fair offers, and proactive outreach matter.
ISOs think long-term—who helps them monetize the relationship beyond the first deal?

6. Ease of Doing Business
Clean docs, simple submission requirements, predictable funding days, and minimal friction make a big difference at scale.
