On paper, treasury and FP&A are best friends. In reality, they’re more like colleagues who technically work together but occasionally question each other’s life choices.
FP&A builds the financial story of the company. Revenue forecasts, cost projections, budgets, scenarios. Treasury looks at that story and asks one very inconvenient question:
“Nice. But when does the cash actually hit the bank?”
That’s where the real interaction starts.
Two Perspectives on the Same Reality
FP&A focuses on profitability and performance. It works largely on an accrual basis. Revenue is recognised when earned, costs when incurred.
Treasury focuses on liquidity. Actual cash in and out. Timing matters. A lot.
A company can be profitable on paper and still run into liquidity issues if cash inflows are delayed or outflows are poorly managed. This is where treasury brings a level of realism that sometimes disrupts beautifully crafted forecasts.
Not to be annoying. Just necessary.
Cash Flow Forecasting: Where It All Comes Together
Cash flow forecasting sits right at the intersection of treasury and FP&A.
FP&A provides the input:
Treasury translates that into:
This translation is where things often get… interesting.
Because assumptions that look fine in a P&L don’t always translate cleanly into cash:
Treasury adjusts for timing, payment terms, seasonality, and real-world behaviour. The result is a cash forecast that reflects how money actually moves.
Or at least tries to.
The Accuracy Problem
Everyone wants accurate forecasts. Few are willing to admit how difficult that actually is.
Cash flow forecasting depends on:
One late input from sales, one overly optimistic assumption, and the forecast starts drifting away from reality.
Treasury often ends up chasing inputs, validating numbers, and explaining variances. FP&A, on the other hand, is trying to keep the bigger picture aligned.
Neither side is wrong. They just operate at different levels of detail.
Scenario Planning and Stress Testing
This is where the collaboration becomes more strategic.
FP&A builds scenarios:
Treasury tests them from a liquidity perspective:
This combination turns abstract scenarios into actionable insights.
A growth plan might look great until treasury shows it requires funding that isn’t secured yet. A downside scenario might look manageable until treasury highlights a liquidity gap in month three.
Not always fun conversations. Usually very useful ones.
Working Capital: The Shared Battlefield
Working capital is where treasury and FP&A constantly overlap.
Receivables, payables, inventory. These directly impact both profitability and liquidity.
FP&A monitors performance metrics:
Treasury looks at:
Improving working capital is one of the fastest ways to unlock cash. It’s also one of the hardest, because it involves multiple departments and competing priorities.
Sales wants to sell. Procurement wants discounts. Operations wants buffer stock. Treasury just wants the cash to show up on time.
Data, Systems, and Reality
Both treasury and FP&A rely heavily on data. And both suffer when that data is fragmented or inconsistent.
Different systems
Different definitions
Different timing assumptions
Without alignment, you end up with:
This is where integration between ERP, TMS, and reporting tools becomes critical. Not because it sounds impressive, but because it reduces friction and improves decision-making.
Where It Goes Wrong
Predictably, a few recurring issues show up:
The result is a disconnect between strategy and liquidity. And that’s exactly where problems start.
Treasury’s Role in the Bigger Picture
A strong treasury function doesn’t just report cash positions. It challenges assumptions, adds timing insight, and ensures that strategic plans are financially executable.
FP&A tells you where the business is going. Treasury tells you whether you can actually get there without running out of fuel.
Put those two together properly, and decision-making improves significantly.
Keep them disconnected, and you’ll eventually run into surprises. Usually at the worst possible moment.
