Outbound Economics FAQ
What is an acceptable Customer Acquisition Cost (CAC) for B2B outbound?
As a standard rule of thumb, your fully loaded Year-1 Customer Acquisition Cost (CAC) should not exceed 30% to 50% of your first-year gross profit. For a $10,000 ACV deal at an 80% gross margin ($8,000 gross profit), your target CAC should be between $2,400 and $4,000 to maintain a payback period under 6 months.
What is included in fully loaded cost per prospect?
Fully loaded cost per prospect includes all direct and indirect expenses: contact data enrichment and email verification ($1–$3), research and founder/SDR labor hours ($3–$10), custom account copywriting ($1–$3), and domain/mailbox sending infrastructure ($0.25–$0.50), totaling ~$7 to $20 per account.
Why does outbound fail for low ACV products (under $3,000)?
Outbound requires multi-stage funnel conversion (meetings → opportunities → deals). Because overall conversion typically sits between 0.2% and 0.8%, acquiring one customer requires hundreds of researched accounts. At $10–$15 per prospect, CAC easily reaches $2,500–$4,000, which exceeds the first-year profit of a low-ticket product.
How can I improve my outbound unit economics without increasing volume?
Improving intermediate funnel stages compounds faster than sending more emails. Tightening your ICP qualification increases meeting-to-opportunity rates, while researching live buyer signals increases positive reply rates, halving your effective CAC without spending more on data.
