Merchant acquisition channels are the routes by which MCA funders find and fund new borrowers. The channel mix determines a funder's cost structure, scalability, paper mix, and competitive moat. As of 2026-06-28, ISO networks still dominate but direct digital marketing and processor partnerships are growing share — driven by both the increasing sophistication of programmatic origination and the persistent challenges of managing ISO networks at scale.
The five primary channels.
1. ISO and broker networks (55–70% of industry volume).
The traditional and largest channel. Independent sales organizations (ISOs) and brokers source merchants, run them through funder portals, and earn commissions (typically 8–15% of advance amount) on funded deals.
- Pros: Scalable; ISOs do the merchant acquisition lift; access to merchants the funder couldn't reach directly.
- Cons: High commission cost; quality varies wildly across ISOs; risk of stacking and double-dipping; ISO loyalty is to whoever pays the highest commission today.
- Top users: Independent funders without strong direct brands — Credibly, Kapitus, Fora Financial, BFS Capital, hundreds of smaller funders.
2. Direct digital marketing (15–25%).
Search engine marketing (Google Ads), social media advertising, content marketing, and direct-to-merchant sales teams that source via inbound leads.
- Pros: Lower commission costs (effectively replacing ISO commission with marketing CAC); direct merchant relationship; renewal and cross-sell potential.
- Cons: Marketing CAC has risen materially (typical 2026 cost-per-funded-merchant via Google Ads: $1,500–$3,500); requires brand-building investment; competitive bidding.
- Top users: OnDeck (now Enova Small Business), Bluevine, Fundbox, Lendio (aggregator model), Bankers Healthcare Group.
3. Processor partnerships (5–15%).
Payment processors (Square, Toast, Clover, Shopify Capital) offer financing to their existing merchant base based on processing volume data they already have.
- Pros: Lowest customer acquisition cost in the industry (effectively zero — the merchant relationship already exists); strong data for underwriting; defaultable income source via direct processor capture.
- Cons: Tied to the parent processor's merchant base; competitive pressure from outside MCAs.
- Top users: Square Capital, Toast Capital, Stripe Capital, Shopify Capital, Clover Capital. PayPal Working Capital (now mostly wound down).
4. Renewal and repeat business (10–20%).
Existing merchants returning for additional capital after paying down a prior advance.
- Pros: Lowest underwriting cost; highest conversion rates; lowest defaults (merchants who repaid once are more likely to repay again).
- Cons: Requires existing portfolio; growth is capped by portfolio size and renewal rates.
- Industry standard renewal rate: 30–50% of paid-off merchants take a second advance; ~60% of those take a third.
5. Referral and rate-shopping platforms (3–8%).
Fundnode-style platforms, Lendio's marketplace, Nav, Fundera, MCA rate-comparison sites that route merchants to funders.
- Pros: Pre-qualified leads with merchant intent already established; transparent pricing reduces friction.
- Cons: Growing competitive channel; can commodify the funder's brand; revenue share with the platform.
- Top users: Smaller funders seeking growth without ISO infrastructure; large funders complementing other channels.
Channel economics — fully-loaded cost per funded merchant.
For a $50K average advance:
- ISO channel: $5,000–$7,500 commission + $500 underwriting = $5,500–$8,000 total CAC.
- Direct digital: $1,500–$3,500 marketing spend + $500 sales + $500 underwriting = $2,500–$4,500.
- Processor partnership: ~$100 (programmatic offer triggered by processing data) + $300 underwriting = $400.
- Renewal: ~$50 (automated offer to existing merchant) + $200 underwriting = $250.
- Platform referral: $500–$1,500 referral fee + $500 underwriting = $1,000–$2,000.
The CAC variance is enormous — and explains why processor-financing arms (Square, Toast) can offer significantly lower factor rates than ISO-channel funders.
Channel mix evolution (2020 → 2026). ISO share has slowly declined as direct digital, processor, and platform channels expand: 2020 was ISO ~75% / Direct 10% / Processor 8% / Renewal 5% / Platform 2%; 2026 sits at ISO ~60% / Direct 18% / Processor 12% / Renewal 7% / Platform 3%.
Channel mix and paper grade correlation.
- A/A+ paper: Direct digital, processor partnerships, and renewals dominate.
- B paper: Mixed — ISOs and direct equally represented.
- C/D paper: ISO-dominated; the funders deepest in subprime paper are almost entirely ISO-sourced.
This is because ISO networks reach merchants who haven't built relationships with banks or processors — typically newer, smaller, or thinner-credit businesses.
Channel-specific underwriting differences.
Funders treat the same merchant differently based on acquisition channel:
- ISO-sourced: More skeptical; stacking and fraud screening more intensive; tighter LTV (loan-to-value).
- Direct: Slightly relaxed because the funder has already validated the merchant's interest through their own marketing.
- Processor partnership: Significantly relaxed because the funder has months of processing data showing real revenue.
- Renewal: Most relaxed; existing payment history provides the strongest underwriting signal.
The channel-economics-to-pricing pass-through.
Funders with lower channel costs can offer: - Lower factor rates (Square Capital can quote 1.18–1.24 on profiles where ISO-channel funders quote 1.28–1.35). - Higher ISO commissions (paradoxically — direct-strong funders use ISO channels selectively and pay top commissions for specific paper). - Faster funding (lower processing cost = more automation).
Strategic channel-mix evolution by funder type.
- Pure-ISO funders (Kapitus, Fora, BFS): Highest channel cost, dependent on ISO relationships, most exposed to ISO disintermediation.
- Hybrid funders (Credibly, CAN Capital, Forward Financing): ISO core with growing direct; building brand to reduce ISO dependence.
- Direct-first funders (OnDeck/Enova, Bluevine): Strong direct channel, ISO as supplement; defensible economics.
- Processor-embedded funders (Square, Toast, Shopify Capital): Lowest channel cost; embedded in payment infrastructure; structural moat.
Common confusions.
First, "ISO commissions are the same as direct marketing CAC." False — ISO commissions are 2–4x higher per funded merchant for most funders.
Second, "Direct marketing is always cheaper." False — for B/C paper, direct marketing CAC can exceed ISO commission because conversion rates are low and bidding is competitive.
Third, "All processor-financing is the same." False — Square, Toast, and Shopify Capital have very different economics and merchant targeting.
The 2026 takeaway. Channel mix is destiny in MCA economics. Funders locked into ISO networks face permanent margin compression; those building direct, processor, or platform channels have structurally better economics. The next 3–5 years will see continued migration toward hybrid and direct-first structures.
