A forecast with one optimistic case invites doubt. This deck gives finance leads a structure that investors and lenders trust: headline outcomes first, then the drivers behind the revenue, the base case, the upside and the downside on separate slides, and finally the actions and owners. Every number sits beside the assumption that produced it.

The sample is a three-year forecast for Alderbrook Advisory, a fictional firm: £4.8M revenue in FY2027, 64% gross margin, EBITDA break-even in month 18, an upside of 15% and a downside of 20% with the lowest 13-week cash balance shown. Replace the client, fee and wage inputs, then the cases, the opening cash and the owners.
