Model the decision before you make it.

Scenario simulation tests a business decision against your cost model before you commit: re-price a customer tier, change the mix, consolidate orders, then compare the projected margin against today's baseline.

Why simulate at all?

A cost model tells you where you stand. A scenario tells you what happens if you move. Once cost is attributed properly, you can copy a baseline, change the assumptions, re-price a tier, drop a product line, consolidate a customer's orders, and see the EBITDA outcome side by side. The numbers your finance team can stand behind in a board meeting, before the decision is taken rather than after.

This is how one distributor worked: the model wasn't a list of customers to cut, it was a roadmap of decisions, each one tested and revisited as the model updated.

Common questions

What is profitability scenario modelling?
Testing a business decision against a cost model before making it: re-pricing a customer tier, changing product mix, or consolidating orders, then comparing the projected margin against the current baseline.
Is the calculator a substitute for a model?
No. The calculator illustrates the shape of the opportunity from a few inputs. A real engagement attributes cost down to the individual customer and order, so scenarios reflect your actual book rather than averages.
