Case 075Costing, pricing and unit economicsHard
Sanchay HR Cloud has Rs 300 crore of revenue, a 68% gross margin and an EBITDA margin of minus 14%, with 15% churn and a 30-month CAC payback. Management wants a 10% margin in two years while growing 25% a year. Which levers, in which order?
1The situation
Sanchay HR Cloud sells payroll and HR software to mid-sized Indian companies. Revenue is Rs 300 crore. Hosting costs 18% of revenue and customer support 14%, so gross margin is 68%. Sales and marketing is 45% of revenue, research and development 25% and general and administrative 12%, so EBITDA is minus 14%, Rs -42 crore.
Gross churn is 15% a year; existing customers expand by about 10% a year. The cost of acquiring a customer is recovered from gross margin in 30 months. Management wants a 10% EBITDA margin in two years while revenue grows 25% a year.
2Your task
Which levers get the company to a 10% margin while keeping 25% growth, how big is each, and why does the order matter?
Quick check
Sales and marketing is the biggest cost. Should the plan start by cutting it?
Worked solution
Try it on paper, then open one step at a time.
30-second answerThe answer to give first
Fix the unit economics first, then let scale do the rest: churn from 15% to 11%, hosting from 18% to 13%, payback from 30 to 27 months, G&A frozen and R&D growing slower than revenue reach about 13% in year 2 at 25% growth. Gross margin rises to 75%; sales and marketing falls to 35% of Rs 469 crore because less revenue has to be replaced and each rupee buys more; G&A and R&D leverage add 10 points. Cutting S&M to 30% first would reach a 5% margin with growth of 13%.
Step 1What do the current numbers say is broken?
Not the gross margin, which is ordinary for software, but the cost of keeping customers and the cost of replacing them. At 15% churn a customer stays about 6.7 years, and at a 30-month payback the company earns back its acquisition cost 2.7 times over that life; a healthy software business wants 3 or more. It is a leaky bucket: Rs 45 crore of revenue walks out each year and Rs 135 crore of sales spend is poured in to replace it and grow. On today's efficiency, that Rs 135 crore buys about Rs 79 crore of new revenue, which after churn and expansion is growth of about 21%, so the plan's 25% is not even funded yet.
Step 2Which levers exist, and how big is each?
Five, and they are not equal. Hosting at 18% is high; re-architecting and reserved capacity can take it to 13%, five points of gross margin. Support at 14% can fall to 12% with self-service, two points. The largest lever is sales efficiency, but it comes from churn and payback rather than from a budget cut: at 11% churn less revenue needs replacing, and at a 27-month payback each rupee of sales spend buys more, so 25% growth in year 2 needs Rs 97 crore of new revenue costing Rs 165 crore, 35% of revenue instead of 45%. Freezing G&A at Rs 36 crore takes it to 7.7% of year 2 revenue, and growing R&D 10% a year while revenue grows 25% takes it to 19.4%.
| Share of revenue | Today | Year 2 | Lever |
|---|---|---|---|
| Revenue, Rs crore | 300 | 469 | 25% growth a year |
| Hosting | 18% | 13% | Re-architecture, reserved capacity |
| Support | 14% | 12% | Self-service, onboarding |
| Gross margin | 68% | 75% | |
| Sales and marketing | 45% | 35% | Churn 15% to 11%, payback 30 to 27 months |
| R&D | 25% | 19% | Grows 10% a year |
| G&A | 12% | 8% | Frozen at Rs 36 crore |
| EBITDA margin | -14% | 13% |
Step 3Why does the order matter so much?
Because the obvious cut kills the growth the margin is supposed to sit on. Cut S&M to 30% of revenue today and, at 15% churn and a 30-month payback, growth falls to about 13%; two years later revenue is Rs 381 crore instead of Rs 469 crore and the margin is about 5%, with a Rule of 40A rough screen for software companies: revenue growth rate plus profit margin, in percentage points, should sum to 40 or more. score of 17 against 38 on the plan. The sequence is therefore: churn and support in the first six months, because they are product and process work that pays back on every customer; hosting in parallel, because it is an engineering project; then sales targeting and pricing to shorten payback; and only then let S&M fall as a share of a bigger, stickier revenue base. G&A and R&D leverage need no decision, only discipline.
Step 4What would you tell management, and what are the limits?
That the 10% target is reachable, that the path runs through retention, and that year 1 will look worse than year 2 because the churn and hosting work costs money before it saves it. Measure the plan on three numbers: gross churn, CAC payback and gross margin; if those move, the margin follows, and if they do not, no amount of budget cutting gets there without shrinking the company. Say the limits: the 11% churn and 27-month payback are targets, not forecasts, the 10% expansion rate is assumed to hold, and the arithmetic treats S&M as buying new revenue in the same year, when in practice there is a lag of a quarter or two. A real plan would be built by cohort.
Where candidates lose it
The common miss is treating S&M as a cost to cut rather than the price of growth. At 15% churn the company must buy back a seventh of its revenue every year before it grows at all; cut the budget and growth collapses, which defeats the point of the margin.
The second is listing levers without sizing them. Five points of hosting, two of support and ten of sales efficiency are different projects with different owners, and the interviewer wants to hear which comes first and why.
What the interviewer asks next
- Churn stays at 15% but payback falls to 20 months. Can the plan still reach 10%?
- How would you price the product differently to improve both payback and churn?
- A buyer would pay 6x revenue for this business at a Rule of 40 score of 40. What is the plan worth against the cut?
