  • Fulfillment and shipping costs per order
  • Returns processing and restocking costs
  • Payment processing fees

Unit Economics to Model

  • Average Order Value (AOV) trend
  • Gross margin by product category
  • Customer Acquisition Cost (CAC) by channel
  • Repeat purchase rate and purchase frequency
  • LTV by customer vintage at 12, 24, 36 months

Key Model Assumptions

Series B models require a formal AOP (Annual Operating Plan) for the current year with monthly actuals-vs-plan tracking. Investors will ask for monthly actuals in the data room and will model variance trends.

  • Return rate by product category
  • CAC by acquisition channel
  • Repeat purchase rate cohort curve
  • Gross margin improvement from volume purchasing

Include a capital allocation memo that justifies the Series B use of proceeds. Show how each dollar maps to specific growth levers and the expected return on that investment.
