Numbers should explain. Not impress without a basis.
A deterministic model with visible assumptions, explicit currency and costs included. Not a customer-results estimate or a replacement for a proposal.
What could better follow-up contribute?
Change the assumptions. See revenue, contribution and costs separately.
Adjust assumptions & costs
Illustrative follow-up example; not an Ironhand quote Initial example in MXN. Amounts are editable assumptions, not published Ironhand prices. Capacity and risk are not added to this projection.
After setup, recurring costs and gradual ramp-up.
4 expected additional customers/steady month · 12% assumed close rate
See the formula & all twelve months
Additional customers = opportunities × close-rate change. Revenue = customers × average sale. Contribution = revenue × margin. Benefits ramp gradually; fixed costs are charged every month. Annual net = monthly benefits − monthly costs − setup. ROI divides that net by all costs. Payback is the first modeled cumulative breakeven, not a guarantee.
