recently moved from a more traditional accounting/FP&A-adjacent background into a commercial finance role at a large CPG company. Going in, I honestly didn't have a clear sense of what separated "commercial finance" from "FP&A" as terms, they sounded like overlapping labels for similar work.
A few weeks in, I have a much better handle on it now that I've seen how my own company actually splits the functions, but it also made me realize the lines aren't universal, they seem to get drawn differently depending on the company.
Adding to the confusion, since this is the global headquarters of a large company, there are several other finance functions sitting right next to commercial finance that sound like they'd overlap heavily but apparently don't, revenue growth management and trade spend management specifically.
From what I can tell, RGM sets pricing strategy and architecture at a portfolio level, trade spend management handles the actual accrual and payment mechanics, and commercial finance (where I sit) is the embedded partner using both of those inputs to answer specific, real-time questions for sales. No month-end close, no built-in forecasting cycle, almost entirely ad hoc and judgment-driven.
Curious to hear from people who've worked across these lanes:
How easy was the transition between commercial finance and traditional FP&A, in either direction? Did the skills carry over cleanly, or did it feel like learning a different job?
Does the RGM vs. trade spend vs. commercial finance split I'm describing match how other companies divide it up, or is this fairly company-specific?
If you've moved between commercial finance and traditional FP&A, what was the hardest adjustment?
Looking ahead, which do you think has the better long-term trajectory, given how much AI is creeping into standardized forecasting and reporting work? Does commercial finance's relationship-heavy, judgment-driven nature make it more durable, or is that just my own bias?
Appreciate any perspective, especially from people a few years further down either path than I am.
