The problem it solves

Without a budget or model, every decision is a guess. Owners cannot see how a new hire, a price rise or a slow month affects profit and cash, and when investors or lenders ask for projections, the numbers are pulled together in a hurry.

What it covers

  • An annual budget built with the people who will deliver it
  • A linked model of profit and loss, balance sheet and cash flow
  • Driver-based forecasts using volumes, prices, headcount and conversion rates
  • Best-case, worst-case and decision-specific scenarios
  • Regular reforecasting against actual results
  • Models ready for fundraising and lending

Who it is for

Businesses planning growth, preparing to raise money or borrow, or facing a major decision such as a new product, location or acquisition.

Good to know in the UK

  • A model is only as good as its assumptions, so the most valuable part of the work is agreeing and documenting the drivers.
  • Comparing budget with actual results each month turns the model into a management tool rather than a one-off spreadsheet.

Questions to ask a provider

  • Will we be able to update the model ourselves?
  • Is it linked to our accounting data?
  • How do you test the assumptions?
  • Is it suitable for a funding round?
