The model and the reporting disagree
One was built from assumptions and the other comes from the systems, so every variance meeting turns into a reconciliation exercise.

Financial modelling
The plan usually lives in a spreadsheet built from assumptions while the actuals come out of the systems, which turns every variance discussion into a reconciliation. We build the model on the same definitions as the reporting, document the calculation, and separate inputs from logic so that somebody other than the author can open it, challenge it and stress it.
Discuss this buildWhen this comes up
One was built from assumptions and the other comes from the systems, so every variance meeting turns into a reconciliation exercise.
A number lands on the page without the operating drivers underneath it, so nobody can see which lever moves it.
The logic is undocumented and fragile, which means it cannot be challenged, stress-tested or handed to anybody else.
The work
Scope varies with the state of your systems. These are the parts that recur.
Revenue, cost, working capital and operating assumptions connected to the measures already defined in your reporting.
A documented, auditable model with the calculation visible and the inputs kept separate from the logic.
The what-if cases a lender or board will press on, built in rather than bolted on afterwards.
What you leave with
You own all of it: the code, the written definitions and documentation aimed at whoever maintains this after us.
How this runs
We establish which commercial question is worth answering here, and what your data, systems and people can realistically support.
We build it, rather than specifying it for somebody else to build. Reconciled continuously against numbers your team already accepts.
Documentation, definitions and a runbook, plus a walkthrough where your team drives and we watch.
Ongoing technical support is quoted separately from the build, so declining it costs you nothing.
