Why acquisition cost matters to you
Every dollar a funder spends to find you is a dollar they need to recover from your factor rate. Customer acquisition cost (CAC) is one of the largest line items in MCA funder economics — often more than loss provisioning and rivaling cost of capital. The channel that brought you to the funder is therefore one of the biggest hidden inputs to what you actually pay.
There are five main channels MCA funders use to acquire merchants. Each has very different unit economics, and merchants who understand which channel they came through often get a sharper sense of how their pricing was set.
Channel 1: ISO brokers
ISO (Independent Sales Organization) brokers are the largest single acquisition channel for most MCA funders — typically 50-70% of new originations come through ISO channels. ISOs market to merchants directly (cold outreach, paid ads, networks, existing relationships), collect applications, and submit them to funders for underwriting.
Funder economics on ISO-sourced deals:
- Commission: typically 5-12% of advance face value, paid at funding
- Effective CAC per funded deal: $3,000-$8,000 on a $50K-$75K advance, financed over the deal life
- Submission-to-funding conversion: typically 15-25%
- Lead quality: highly variable — top ISOs deliver clean files; bottom ISOs spam funders with shoppers
The ISO commission gets baked into the factor rate. On a $50K deal at 1.30 with a 10% ISO commission, the funder paid $5,000 to acquire you — that's roughly 4-5 points of factor rate (or 8-10% of the gross fee) consumed by acquisition cost alone. Direct funders can offer 1.25 on the same merchant because they don't have that cost.
ISO economics also drive broker behavior. Brokers earning commission on factor rate have a financial incentive to push you toward higher factors (more commission). The better ISOs resist this temptation; the worse ones lean into it aggressively. This is the source of the "broker markup" problem — see our ISO broker economics guide for the detailed mechanics.
Channel 2: Lead aggregators / marketplaces
Lead aggregators sit between the merchant and the funder. The merchant fills out a form on the aggregator's site (Lendio, Fundera, Lendr, etc.); the aggregator captures the application, sometimes does basic qualification, then sells the lead to multiple funders.
Funder economics on aggregator-sourced deals:
- Lead cost: $50-300 per lead, depending on quality
- Lead-to-funding conversion: 5-15% typically (lower than ISO because leads are less qualified)
- Effective CAC per funded deal: $1,000-$3,000
- Lead quality: highly variable — some aggregators do real qualification, some just resell raw form fills
Aggregator-sourced deals tend to be cheaper for the funder than ISO-sourced deals but more expensive than direct or renewal channels. The aggregator economics are generally pass-through — a meaningful saving vs ISO commission, but funders still have to recover the CAC.
A specific quirk of aggregator channels: leads are usually sold to multiple funders simultaneously, so funders are racing to call the merchant first. Merchants who fill out aggregator forms get 5-15 calls within the next 48 hours from different funders. This is the #1 source of "broker spam" complaints in the MCA industry.
Channel 3: Direct marketing
Some funders run substantial direct-to-merchant marketing operations. SEO content, paid search, social media ads, accounting-platform integrations (QuickBooks, Xero), retargeting, email lists, and brand-driven inbound. OnDeck, Bluevine, and Kabbage (before acquisition) were the largest direct funders historically.
Funder economics on direct-sourced deals:
- Blended CAC: $800-$2,500 per funded deal for well-run direct programs
- Conversion: 8-20% application-to-fund (depending on segment)
- Lead quality: typically high — merchants finding the funder directly are usually doing real research
Direct marketing only works at scale. Building a direct funnel costs $5M-$20M+ per year before it pays back. Only the top 10-15 funders run real direct operations; everyone else relies on ISO and aggregator channels.
For merchants who can find these funders directly, the savings are real — typically a 2-4 point factor rate advantage vs equivalent ISO-sourced offers from the same funder. The challenge is that direct funders are also more selective on credit (they can be choosy because their channel is cheap) and harder to reach for merchants outside their target profile.
Channel 4: Matching platforms
A newer category sitting between direct marketing and aggregators: matching platforms that route applications to a small number of best-fit funders based on merchant profile, rather than broadcasting to many. The economics fall between aggregators and direct:
- Per-funded deal cost: 1-3% of advance face (vs 5-12% ISO commission)
- Conversion: 25-45% application-to-fund (higher than aggregators because the match is more accurate)
- Lead quality: high — pre-qualified and routed only to funders likely to write the deal
For funders, matching platforms are a high-quality, low-cost channel. For merchants, they offer the curation benefits of a good ISO without the markup-driven incentive misalignment of pure broker channels. Fundnode operates in this category.
Channel 5: Renewals
Renewals are the cheapest acquisition channel by orders of magnitude. A merchant who paid down 50%+ of their original advance in good standing is a known quantity — the funder has bank statement data, payment history, and a verified relationship. Renewal CAC is just the time of the relationship manager who reaches out plus any underwriting refresh; typically $50-300 per funded renewal.
Why this matters: renewals are where funders make their best profits, and where merchants get either their best rates or their worst depending on how the relationship is managed.
Best case: the funder offers a "renewal discount" — slightly better factor rate or higher amount or longer term — to reward the relationship. Some funders explicitly offer 5-10% better terms on renewals.
Worst case: the funder leverages your operational dependency. You need the renewal capital to keep operating. The funder knows it. They quote the renewal at the same rate as a first-time advance — or worse, slightly higher — because they have pricing power. This is the dynamic our renewal mistakes article covers in detail.
Channel-mix economics for a typical funder
A mid-sized MCA funder in 2026 might have this channel mix:
- ISO brokers: 55% of originations, $5,500 average CAC per deal
- Lead aggregators: 15%, $2,000 average CAC
- Direct marketing: 10%, $1,800 average CAC
- Matching platforms: 5%, $1,200 average CAC
- Renewals: 15%, $200 average CAC
Blended CAC across the book: roughly $3,500-$4,000 per funded deal. On a $50K average advance, that's 7-8% of advance face — a major component of cost structure.
Funders who can shift their mix toward direct, matching, and renewal channels materially improve their economics — and either pocket the gain as margin or pass part of it to merchants in the form of lower rates. This is one of the levers the best-positioned funders use to grow profitably.
How to use this as a merchant
Three practical takeaways:
- If you fit A or B paper, try direct channels first. Funders like OnDeck and Bluevine want clean credit and offer direct-app pricing that beats most ISO quotes. Worth a try before you bring a broker into the picture.
- If you do use a broker or platform, ask about their channel positioning. A good broker should be able to tell you which funders they have direct API access to and which they shop traditionally. Direct API access usually means better economics.
- Treat your first deal as a relationship investment. The renewal economics on a successful first deal are dramatically better than starting fresh with a new funder. Pick a funder you'd want to work with again, not just the cheapest current quote.
Frequently asked questions
- What's the cheapest channel for a funder to acquire merchants?
- Renewals. A merchant in good standing renewing their advance costs the funder almost nothing — no broker commission, no lead cost, no underwriting from scratch. CAC on a renewal is typically $50-200; on a new ISO-sourced deal it's $3,000-$8,000.
- How much does an ISO commission cost a funder?
- Typically 5-15% of the advance face value, paid upfront and amortized over the life of the deal. On a $50,000 advance with a 10% ISO commission, the funder pays $5,000 to the broker — a meaningful cost that drives factor rates higher when sourcing through brokers vs direct channels.
- What's a lead aggregator?
- Companies like Lendio, Lendr, and similar that collect merchant applications, qualify them lightly, and sell the leads to multiple funders for $50-300 per lead. Funders use them for top-of-funnel volume; conversion rates are typically 5-15%, so the effective cost per funded deal is $1,000-$3,000.
- Do direct-to-merchant funders exist?
- Yes. Funders like OnDeck, Bluevine, and a few others run substantial direct marketing — SEO, paid search, content, partnerships with accounting platforms. Direct CAC can be lower than ISO commission for the right credit profile, especially A and B paper. C and D paper is mostly broker-sourced.
- Why does this affect my rate?
- Because acquisition cost gets priced into the factor rate. A funder paying $5,000 to a broker to source your deal has to recover that cost over the life of your advance. A direct-marketing funder paying $1,500 in blended CAC has 70 basis points more margin to work with.
