Using transactions log data and marketing spend data we calculate:
- Monthly sales over time
 - Total customers acquired
 - Customer acquisition cost (CAC)
 - Distribution of spend per purchase
 - Initial versus repeat sales volume
 - Initial versus repeat average order value (AOV)
 - Sales and AOV by source
 - First-purchase profitability
 - Cohorted sales (the “C3”)
 - Revenue retention curves
 - Cumulative spend per customer
 - Distribution of total spend by customer
 - Customer concentration (“Pareto”) chart
 
What the analysis summarize:
- Growth
 - Unit costs
 - Unit profitability (unit economic performance)
 - Retention
 - Heterogeneity (customers, time)
 - Yield on CAC
 - CLV / CAC
 - Monthly/Annual Recurring Revenue (MRR/ARR)
 - Average Revenue Per User (ARPU)
 - Logo churn
 - Revenue Churn
 - Weekly/Monthly/Annual Active Users (DAU/MAU/AAU)
 - Gross Margin
 - Contribution Margin
 - Payback Period
 - Magic Number: Net new ARR divided by sales & marketing spend
 - Rule of 40: Growth rate plus profit margin should exceed 40%
 
- Weibull-Gamma acquisition model
 - Exponential-Gamma retention model
 - Point process transaction model
 - Simulating order flow dynamics
 - Acquisition process
 - Purchase process
 - Spend process
