Gross margin here is illustrative only — it shows the margin on a single client with the full GTM spend attributed to it. Delivery cost is already captured in acquisition cost, so it is not subtracted again in the cashflow model below.

04 —Cashflow model

Six months, month by month.

Month 1 closes are held at zero, assuming a sales cycle of at least one month. Closes from month 2 onwards default to your projected funnel — edit them to model ramp-up. Domains are billed annually in month 1.
