A sample answer to question 1

What does a commercial finance manager do, and how does it differ from a financial controller or FP&A role?

A commercial finance manager supports the revenue side of the business: pricing, contracts, customer and product profitability, bids and commercial negotiations. The financial controller is mostly accountable for accurate ledgers, controls and statutory reporting, and FP&A for budgets and forecasts across the whole business. In commercial finance, I sit alongside sales, marketing and operations, so my questions are things like, what margin does this contract earn, what happens to profit if we offer a rebate, or which customers cost more to serve than they bring in. A typical week includes reviewing deal proposals, building models, challenging discount requests, explaining the margin variance to the sales director and preparing the commercial elements of the forecast. Success needs credibility with non-finance colleagues, strong Excel, and the confidence to say no with a good reason, while still helping the business win profitable work.

Common mistake to avoid: Describing it as management accounts only; being purely a gatekeeper
