A forecast can be useful for running a business and still lack the evidence needed to defend it.

What happens when accounting and FP&A report different revenue numbers for the same month, and the disagreement comes down to how a contract is interpreted? In this episode of FP&A Today, Sarah Schlott welcomes Norm Osumi to explore the judgment calls that sit between financial reporting, business performance and forward-looking forecasts.

Through a SaaS revenue-recognition example, Norm examines why bookings, billings and recognized revenue are not interchangeable, and how implementation fees and sales commissions complicate the picture. The conversation then turns to EBITDA and adjusted EBITDA, where excluding recurring expenses or making aggressive add-backs can change the story a business tells about its performance.

The central question is what happens when an FP&A forecast becomes evidence for an auditor, lender or investor. Norm discusses an auditor requesting five years of purchase orders to substantiate future revenue and explains why assumptions around growth, customer activity and the sales pipeline need to be reasonable and documented. For smaller finance teams, the lesson is not to build more elaborate models. It is to understand which numbers matter, what supports them and when to bring accounting into the conversation.

Key Moments

  • Recognized revenue, bookings and billings serve different purposes. A sound FP&A forecast needs to account for the underlying revenue-recognition rules.

  • SaaS implementation fees and subscriptions can produce different monthly revenue outcomes depending on the contract and performance obligations.

  • Sales commissions raise both operational and accounting questions, especially when bookings, revenue and related costs fall into different periods.

  • Adjusted EBITDA requires judgment. Recurring expenses cannot simply become one-time adjustments because excluding them creates a more attractive result.

  • Forecasts can become part of an audit, valuation or financing process. Assumptions may need to be supported by customer activity, purchase orders and a credible growth pipeline.

  • Smaller finance teams still benefit from documenting the handful of assumptions that materially drive their forecasts.

  • Repeated misses against publicly communicated financial projections can damage management's credibility.

  • FP&A and accounting need shared definitions, clear communication and a process for challenging assumptions before numbers reach external stakeholders.
