Customer acquisition cost (CAC) is the most important profitability metric in MCA funder economics. CAC variations between funders explain why some can offer 1.18 factor and others quote 1.40 on the same merchant profile.
Definition.
CAC = total cost to acquire one funded merchant. Includes:
- Marketing spend (paid acquisition, content, brand).
- Sales spend (ISO commissions, channel-management staff, telemarketing).
- Conversion overhead (underwriting cost on declined applications).
- Onboarding cost (KYC, bank verification, contract execution).
Industry composite ranges (2026).
- Platform-native (Toast Capital, Square Capital, Shopify Capital): $200–$800 per funded merchant.
- Direct-to-merchant digital (BlueVine, OnDeck legacy): $800–$2,500.
- ISO-channel funders (most of the industry): $1,500–$4,500.
- Cold outbound / telemarketing-heavy: $3,000–$6,000.
Blended industry composite: $2,000–$3,500.
Why CAC varies so much.
- Conversion funnel efficiency. A funnel that converts 25% of leads to funded has 1/4 the CAC of one that converts 6%.
- Channel mix. Platform-native is 5–10x cheaper than ISO; cold outbound is 2x more expensive.
- Brand strength. Funders with strong SEO and organic brand search pay less per lead.
- Underwriting waste. Funders with sloppy front-end qualification underwrite many declines, inflating CAC.
- Renewal economics. Funders that count renewals in CAC denominator have artificially low CAC numbers.
CAC components by channel.
ISO channel: - ISO commission: $1,200–$3,500 (8–15% of advance). - Channel management overhead: $100–$400. - Underwriting cost (loaded): $200–$500. - Total: $1,500–$4,500.
Direct digital channel: - Paid search/social: $500–$1,500. - Content/SEO amortized: $50–$200. - Conversion funnel staff: $150–$400. - Underwriting cost: $100–$300. - Total: $800–$2,500.
Platform partnership channel: - Revenue-share with platform: $100–$400. - Onboarding cost: $50–$200. - Underwriting cost (API-automated): $30–$100. - Total: $200–$800.
The CAC-to-LTV ratio.
Healthy funders target 1:3 CAC-to-LTV (every $1 spent acquiring generates $3 of merchant lifetime value).
- Elite funders (Credibly, Forward Financing): ~1:5.
- Average funders: ~1:3.
- Struggling funders: ~1:1.5 (treading water).
- Distressed funders: <1:1 (losing money on every merchant).
Worked example: how CAC affects funder pricing power.
Two funders, same A-paper merchant, same $50K advance, 9-month term:
- Funder A (platform-native, $500 CAC): Factor 1.22, total fees $11,000. Net of bad-debt ($1,500) + servicing ($400) = $9,100. CAC $500. Net profit per deal: $8,600.
- Funder B (ISO-channel, $3,500 CAC): Factor 1.32, total fees $16,000. Net of bad-debt ($1,500) + servicing ($400) = $14,100. CAC $3,500. Net profit per deal: $10,600.
Funder A's lower CAC enables 10-point lower factor while maintaining $8,600 profit per merchant. This is the platform-channel economic moat.
How funders reduce CAC.
- Push more volume to platform partnerships (highest leverage move).
- Invest in SEO and organic content to reduce paid-search dependency.
- Tighten ISO scorecards to eliminate low-converting ISOs.
- Automate underwriting to reduce cost per decision.
- Increase renewal rate to amortize CAC over more advances per merchant.
How ISOs can read funder CAC.
- Funders that aggressively cut ISO commission are usually trying to reduce CAC — sometimes at the cost of relationships.
- Funders that build direct-merchant brands (TV ads, content marketing) are pivoting channel mix.
- Platform-native funders rarely use traditional ISOs.
2026 CAC trends.
- Platform channel growth pulling industry-blended CAC down 10–15% from 2024.
- AI-driven underwriting reducing per-decision cost 40–60%.
- ISO consolidation — fewer, larger ISOs at top funders.
- Search-engine cost-per-click for MCA keywords up 8–12% YoY.
Common confusions.
First, "CAC = ISO commission." False — ISO commission is a component, not the total.
Second, "lower CAC = better merchants." Not always — platform-native CAC is low because of data efficiency, not merchant filtering.
Third, "CAC is publicly reported." No — proprietary; estimated from public disclosures and industry surveys.
Fourth, "CAC includes renewal cost." Usually no — renewal CAC is reported separately as a much lower figure.
Fifth, "high CAC = unprofitable funder." Not necessarily — paired with high LTV, it can be very profitable.
