what would make growth work worth it?

start with a conservative scenario.

Use the same time period for revenue and cost. Include agency fees, advertising, tools, and internal effort in program cost. Gross margin should already account for fulfillment; do not subtract those delivery costs twice.

The model assumes the added inquiries are attributable to the program and convert at your entered rates. Verify those assumptions against collected results. Traffic changes, seasonality, sales follow-up, and customer mix can affect outcomes.
