Connect the raise to milestones.
Start with the amount of funding being considered, the activities it supports and the milestones the business needs to reach. Separate cash already committed from funding still being sought. The model should show the consequence if a raise is delayed or smaller than planned.
Build revenue from a mechanism.
For a sales-led business, consider leads, conversion, contract size and time to close. A subscription business may need customers, pricing, expansion and churn. A simple growth percentage can be useful as a sensitivity, but it should not replace the underlying commercial explanation.
Make hiring and investment explicit.
Model roles, start dates and full employment cost assumptions, alongside product development, capital spending and material commitments. Where payroll or tax inputs are relevant, agree the applicable assumptions with the appropriate advisers. Do not hide significant spending inside an unexplained overhead percentage.
Give the downside case equal attention.
Test slower sales, lower margins or delayed funding. Identify the cash low point and actions management might consider. The model supports a funding discussion; it does not establish investor appetite, guarantee a valuation or promise that the business will meet its forecast.
