## Cash forecasting is moving closer to the operating business

Cash forecasting has traditionally been a periodic finance exercise built from bank balances, spreadsheets and submissions from business units. That process can still support planning, but it struggles when cash positions change quickly, payment timing shifts or operating data arrives after decisions have already been made.

The growing response is to move forecasting closer to real time. The [2025 PwC Global Treasury Survey](https://www.pwc.com/us/en/services/consulting/finance-accounting-transformation/library/2025-global-treasury-survey.html) describes a treasury function becoming more connected, data-driven and focused on cash visibility. The strategic change is not simply faster reporting. It is the ability to update financing, investment and working-capital decisions as the underlying business changes.

## Why periodic forecasting is under pressure

A monthly forecast may be adequate for some long-term decisions, but short-term liquidity is affected by events that occur every day: customer receipts, supplier payments, tax obligations, payroll, debt settlements and currency movements. When the forecast depends heavily on manual collection, finance teams can spend much of the cycle assembling data rather than analysing it.

PwC found that many large companies still manually collect and consolidate forecasting data, while poor data quality and limited tools remain common barriers. The problem is therefore as much about operating process as technology. Real-time finance requires a more continuous flow of reliable information.

## Cash visibility and cash forecasting are converging

Historically, cash positioning answered the question, “Where is our cash now?” while forecasting answered, “Where will it be later?” Digital connectivity is bringing those questions together. APIs, virtual accounts and modern treasury systems can update balances and transaction information more frequently, giving forecasting models a fresher starting point.

This reduces the gap between actual and expected cash. A forecast can be recalibrated as payments arrive, invoices are delayed or business units change spending plans. The result is less dependence on a static snapshot and more emphasis on rolling liquidity intelligence.

## Working capital becomes part of the forecast engine

Cash forecasting improves when it is connected to the drivers of working capital rather than treated as a separate treasury model. Receivables, payables and inventory all contain signals about future cash movements. A change in customer payment behaviour may matter more than a small change in the sales budget; an inventory build may consume liquidity before it appears clearly in the income statement.

Deloitte's [2025 working-capital analysis](https://www.deloitte.com/us/en/services/consulting/articles/working-capital-management-report.html) highlights the renewed importance of structural working-capital discipline as companies navigate funding costs and volatility. Better forecasting allows finance teams to see those operational changes before they become a liquidity surprise.

## Automation is reducing the cost of frequent forecasting

The traditional objection to more frequent forecasting is workload. If each update requires dozens of spreadsheets and manual reconciliations, moving from monthly to weekly or daily forecasting simply multiplies effort. Automation changes that constraint by pulling data directly from banks, enterprise systems and payment platforms.

The [2025 AFP Treasury Benchmarking Survey](https://www.afponline.org/training-resources/resources/survey-research-economic-data/Details/treasury-benchmarking) reports that cash management and forecasting are among treasury's top priorities and that cash or liquidity forecasting remains one of the profession's most challenging tasks. More mature teams automate a larger share of the forecasting process, allowing staff to spend more time on exceptions and scenarios.

## AI is useful, but only with good inputs

Machine learning and generative AI can help identify patterns, estimate payment timing, detect anomalies and generate scenarios. Their value is greatest where companies have enough clean history and consistent transaction data to support prediction. The technology can reduce manual work, but it cannot make weak data reliable.

A [Deloitte review of emerging treasury trends](https://www.deloitte.com/content/dam/assets-zone2/ch/en/docs/services/audit-assurance/2025/ch-deloitte-emerging-trends-in-corporate-treasury.pdf) makes a useful distinction by time horizon: predictive tools are particularly relevant to short-term forecasts, while medium-term forecasts depend more on scenario building and long-term forecasts remain closely tied to strategy and macro assumptions. Different horizons therefore need different methods.

## Scenario planning becomes more dynamic

A real-time finance function does not imply that the forecast is always precise. In volatile conditions, the more useful question may be how liquidity changes under different assumptions. Finance teams can model slower collections, higher inventory, changing interest costs or delayed projects and then update those scenarios as new data arrives.

This makes forecasting a decision tool rather than a promise of certainty. Management can see where the business has liquidity headroom, when financing might be required and which operational levers would create the largest cash benefit under stress.

## Forecast accuracy needs better measurement

More frequent forecasting creates an opportunity to improve measurement. Instead of looking only at the final variance, companies can track which categories consistently miss, whether errors are caused by timing or amount, and which business units provide the least reliable inputs.

That feedback loop is important because forecasting quality improves when responsibility is shared. Treasury may own the model, but sales, procurement, operations and tax often control the underlying decisions. A real-time forecast therefore needs governance around data ownership and forecast accountability.

## Better forecasting changes capital decisions

The strategic benefit appears when cash forecasts influence action. A company with stronger visibility can reduce idle cash, time borrowing more efficiently, manage revolver usage, plan debt issuance and decide when surplus liquidity can be invested. It can also evaluate capital expenditure with a clearer view of short-term funding needs.

PwC's treasury survey notes that leading organisations are combining real-time liquidity tools, centralised payment models and AI-enhanced forecasting. These capabilities reinforce one another: the more connected the cash architecture becomes, the more quickly finance can act on the forecast.

## Real time does not mean every second

The phrase “real-time finance” can be misleading if interpreted literally. Not every company needs second-by-second cash forecasting. The useful frequency depends on payment volumes, business volatility, funding structure and decision speed. For some organisations, a reliable daily view may be transformative; for others, intraday visibility may be justified.

The objective is to shorten the distance between business events and financial decisions. A forecast should be updated quickly enough to matter, but not so frequently that the process creates noise without improving action.

## From reporting function to liquidity intelligence

Cash forecasting is becoming part of a wider shift in finance from retrospective reporting toward forward-looking operating intelligence. Technology makes that shift possible, but the hard work remains organisational: improving data, connecting systems, defining ownership and agreeing how forecast changes should trigger decisions.

Companies that succeed will not eliminate uncertainty. They will become better at seeing it sooner. That is the value of real-time cash forecasting: not perfect prediction, but a faster and more disciplined link between operations, liquidity and capital allocation.

## Key questions

**What is real-time cash forecasting?**

It is a more continuous approach to liquidity forecasting that uses frequently updated bank and operating data so finance teams can revise expected cash positions and scenarios more quickly.

**Does AI make traditional treasury forecasting obsolete?**

No. AI can improve pattern recognition and automate parts of forecasting, but data quality, business judgement, scenario design and accountability remain essential.

**Why does cash forecasting matter strategically?**

A better forecast can improve funding timing, working-capital decisions, debt management, investment of surplus cash and the company's ability to respond to operational shocks.
