The CAC Problem
Customer acquisition cost is one of the most important metrics in any business. It tells you how much you're spending to win each new customer. For many B2B companies, CAC has been climbing steadily as advertising costs rise and competition intensifies.
The biggest driver of high CAC in B2B is usually the sales team. Base salaries, benefits, office space, tools, and management overhead add up fast. And because salespeople need time to ramp, you're often paying full cost for months before seeing proportional output.
How Agents Change the Equation
Commission based agents flip the cost structure. Instead of paying upfront and hoping for results, you pay a percentage of revenue only after a deal closes. Your CAC for agent sourced deals is simply the commission paid, which is directly proportional to the deal value.
Compare this to a salaried rep who costs $150,000 per year fully loaded and closes 20 deals. That's $7,500 per customer in sales cost alone. An agent at 12% commission on a $10,000 deal costs you $1,200 per customer. The maths speaks for itself.
Blending Your Channels
Most businesses won't replace their entire sales function with agents, and they shouldn't. The goal is to add an agent channel alongside your existing efforts to bring down your blended CAC.
Keep your best salaried reps focused on enterprise accounts and strategic relationships. Use agents for mid market outreach, new territory expansion, and product lines that don't justify dedicated headcount.
Tracking CAC by Channel
To measure the impact, you need to track CAC separately for each channel. Zepys provides the tracking infrastructure for your agent channel, showing you exactly what you're paying per closed deal, per agent, and per product line. This makes it straightforward to compare agent CAC against your other channels.
Optimising Over Time
Once you have data, you can optimise. Invest more in the agents and territories that produce the lowest CAC. Improve your sales materials to increase agent close rates, which drives CAC down further. Adjust commission rates to find the sweet spot between agent attractiveness and profitability.
The Compounding Benefit
Lower CAC means higher margins, which means more cash to reinvest in growth. That reinvestment attracts more and better agents, which drives more revenue at low CAC. It's a virtuous cycle that gives lean businesses a genuine structural advantage over competitors who rely on expensive, fixed cost sales teams.
