ISO (MCA) explained
The two glossary sources gathered in this research define it slightly differently. lendsaas describes an ISO broadly as an external broker entity sourcing merchants for commissions, while mcarocket adds the formality emphasis: an established broker with formal funder relationships. In practice, ISO and broker are used close to interchangeably across the market, the same way the shared B2B glossary's BDR and SDR entries note those two roles blur together in everyday use.
Segment behavior splits along deal-flow lines rather than the ISO-versus-broker label itself. New and small ISOs are price-sensitive and typically start on aged leads before graduating to live transfer or appointment spend, while established shops and high-volume floors need consistent deal flow at scale, Lead Tycoons explicitly positions its own offer for high-volume sales floors requiring 50 to 200 leads daily.
How to become an MCA broker is a confirmed real search query, verified via autocomplete during this research, with no single dominant, comprehensive answer identified anywhere in the sources reviewed, a genuine content gap for anyone entering this side of the industry.
Why it matters when you're buying
If you're evaluating a lead or appointment vendor's target market, ask whether their offer is built for a new or small ISO still working aged leads, or an established floor buying live transfers and full submissions, since the two segments have very different price sensitivity and deal-flow needs.
