Vantage Cloud: Segment Budget Shift Between Enterprise and SMB
Vantage Cloud sells workflow software to two segments. Enterprise has 120 customers, average contract value $48,000 per year, 70% gross margin, 5% annual churn, and $22,000 acquisition cost per customer. SMB has 900 customers, average contract value $3,600, 55% gross margin, 22% annual churn, and $900 acquisition cost. The VP of sales proposes moving 30% of the $4.2 million annual sales and marketing budget from enterprise to SMB because SMB payback is shorter and the team can close more logos. The enterprise sales director warns that enterprise is 64% of total revenue and that the largest 10 customers represent 28% of enterprise revenue; two are in renewal talks. The CEO likes the SMB growth story but worries about optimizing for payback and starving the business. The board wants a segment-level recommendation with a three-year view.
1. Compare the two segments on acquisition payback, lifetime value, and lifetime-value-to-acquisition-cost ratio. Why do the metrics point in different directions?

Enterprise annual gross profit per customer is $48,000 × 0.70 = $33,600. Payback is $22,000 / $33,600 = 0.655 years, or about 7.9 months. At 5% annual churn, expected life is 1/0.05 = 20 years, so LTV is $33,600 × 20 = $672,000. LTV/CAC is $672,000 / $22,000 = 30.5.
SMB annual gross profit per customer is $3,600 × 0.55 = $1,980. Payback is $900 / $1,980 = 0.455 years, or about 5.5 months. At 22% annual churn, expected life is 1/0.22 = 4.55 years, so LTV is $1,980 × 4.55 = $9,000. LTV/CAC is $9,000 / $900 = 10.0.
The metrics diverge because payback measures how fast cash is recovered, while LTV measures total profit over the relationship. SMB wins on speed because its CAC is low. Enterprise wins by roughly 3× on LTV/CAC because enterprise customers stay far longer and generate much more gross profit per logo. A payback-only rule would systematically underinvest in the segment with the highest lifetime value.
2. Evaluate the proposed 30% budget shift. Use segment economics, revenue concentration, and a three-year view.

A 30% shift moves $1.26 million. At $900 per SMB acquisition, that could fund about 1,400 gross SMB customers, though 22% churn means a large share must be replaced just to stand still. At $22,000 per enterprise acquisition, the same money funds about 57 enterprise customers.
Three-year gross profit, ignoring expansion, illustrates the tradeoff. Enterprise: 57 × $33,600 × (1 + 0.95 + 0.9025) ≈ $5.46 million. SMB: 1,400 × $1,980 × (1 + 0.78 + 0.6084) ≈ $6.62 million. On a static three-year calculation, the SMB shift looks competitive or better, but this assumes the SMB team can absorb 1,400 additional acquisitions without CAC rising or saturation, and it ignores revenue concentration risk.
Enterprise is 64% of revenue. The top 10 enterprise customers are 28% of enterprise revenue, or about $1.61 million. A single top-10 loss at 70% margin removes roughly $113,000 of annual gross profit, equivalent to about 57 SMB customers. Two renewals are already at risk. A 30% cut to enterprise coverage could worsen retention at exactly the wrong moment.
3. What recommendation should go to the board, and which metrics would you use to judge whether the shift is working?
Read the worked answer
Recommend a smaller, staged shift: move 10% to 15% of the budget, not 30%, and protect enterprise coverage for the two renewal accounts and the top-10 cohort. Use the released budget to test SMB acquisition with a defined CAC ceiling and a 90-day cohort review. If SMB CAC stays at or below $900 and 90-day logo churn is no worse than 6%, increase the shift; if enterprise pipeline coverage or renewal probability falls, reverse it.
Metrics should include segment CAC payback, LTV/CAC, net revenue retention, gross logo churn, and enterprise pipeline coverage. Add a concentration metric: top-10 enterprise revenue at risk and renewal probability. Also track SMB saturation, such as CAC by cohort and lead conversion by channel, because the SMB payback advantage depends on acquiring many low-cost logos without bidding up acquisition cost.
The board should not choose on payback alone. A balanced portfolio keeps the high-LTV enterprise base funded while testing whether SMB can grow efficiently.
