Audited planning profile

This couple ten-year profile applies a 2× editable baseline across 120 model periods to the design project compare model.

USE THIS PROFILE TO

Turn operating inputs into a transparent price, margin, capacity or cash-runway decision.

DECISION RULE

Use the difference between option A and option B; keep the scale and horizon identical for both. Agree on shared inputs and ownership before comparing the two-person result. Use a wide uncertainty range; small recurring assumption errors compound substantially over ten years.

NOT INCLUDED

Taxes, contract risk, payment delays, staff variability, compliance costs and exceptional expenses are not inferred automatically.

VERIFY BEFORE ACTING

Reconcile the inputs with current invoices, payroll, contracts and a recent operating period.
