Cash Flow Forecasting: Build Accurate Projections From Your Live Data
Your cash position is always three weeks out of date because the forecast lives in a spreadsheet nobody trusts. Invoicing, banking and expenses stay in separate systems, so leadership plans payroll, tax and supplier commitments from financial projections that are already wrong.
We connect those feeds into a rolling 13-week cash flow forecast that updates as transactions land.
Sound Familiar?
These are the exact cash management issues our clients faced before a live forecast:
- Your rolling cash forecast lives in a spreadsheet nobody fully trusts
- Invoicing, banking and expense data are stitched together by hand every week
- By the time leadership sees the numbers, the cash position is already three weeks stale
- Payroll, tax and supplier commitments are planned from a model that drifts 20%+ by mid-horizon
- One broken formula or late bank export can hide a shortfall until it is too late to act
IBM research finds 88% of spreadsheets contain at least one error, and FP&A teams still spend nearly half their time collecting and validating data. A cash model that is wrong by week eight is not cash management: it is a liability when payroll, SARS payments or lender covenants land.
What the Rolling Forecast Actually Does
Transactions land → cash position updates → 13-week runway refreshes. No Friday export marathon.
Feeds Connect
Invoices, bank clearances and approved expenses sync into one cash model
Week Rolls Forward
Actuals replace Week 1, a new Week 13 is added, and assumptions refresh from variance
Gaps Surface Early
Shortfalls against payroll, tax or supplier weeks appear while you still have options
Leadership Decides
Finance walks into the Monday meeting with a cash position the board can trust
Everything You Need for Reliable Cash Management
Live Invoicing Feed
Open invoices, expected receipts and ageing pull straight from Xero, Sage or QuickBooks into the rolling forecast as they change.
Banking & Balance Sync
Actual bank balances and cleared transactions refresh the opening cash position automatically, so Week 1 is never a guess.
Expense & Payroll Calendar
Approved expenses, recurring supplier payments, payroll runs and tax dates land as dated outflows in the same 13-week model.
Rolling 13-Week Engine
Each week drops completed actuals, adds a new Week 13, and recalculates the cash runway without rebuilding the workbook.
Variance Alerts
Material misses against prior-week forecasts trigger alerts before payroll, VAT or loan covenants become a crisis.
Leadership Dashboard
CFOs and finance leads see a single cash position board packs can trust, updated as transactions land rather than after Friday's export.
Sources We've Connected Into Cash Forecasts
From Eight Hours a Week to 45 Minutes
How a 45-person services group stopped flying blind on payroll and supplier weeks with a live rolling forecast.
The Spreadsheet Process
- Controller exported AR, AP and bank CSVs every Friday afternoon
- Eight hours to rebuild the 13-week model before Monday's leadership meeting
- Near-term accuracy hovered around 65%, with larger misses after week eight
- One delayed receipt plus an early supplier draw almost missed payroll
- Board packs used numbers that were already three weeks stale
The Live Forecast
- Invoicing, banking and expenses feed a rolling 13-week model automatically
- Controller reviews variance and overrides in about 45 minutes
- Weeks 1–4 regularly clear 90%+ accuracy against actuals
- Payroll and VAT weeks flagged two to three weeks ahead
- Leadership sees the same cash position finance trusts

Frequently Asked Questions
What is a rolling 13-week cash flow forecast?
It is a weekly cash management model covering the next quarter. Each week you convert Week 1 to actuals, drop it, and add a new Week 13. Built from invoicing, banking and expense data rather than the P&L, it answers whether you can meet payroll, tax and supplier commitments on time.
Which systems can feed the forecast?
We commonly connect Xero, Sage and QuickBooks for invoicing and payables, bank feeds for cleared balances, and expense or payroll calendars for dated outflows. If your ledger or bank has an API or reliable export, we can include it.
Will this replace our existing spreadsheet?
Most clients retire the manual rebuild once the live model proves itself in a parallel run. You keep the ability to override assumptions, but the data collection and roll-forward stop being a full-day job every week.
How accurate can a live rolling forecast get?
Direct-method rolling 13-week models commonly land around 8–12% MAPE when fed from operational data, versus 22–35% error when cash is estimated from monthly P&L alone. Near-term weeks (1–4) typically reach 90%+ accuracy once variance analysis is in place.
How long does implementation take?
A focused multi-feed cash forecast build usually takes 3–6 weeks from scoping to go-live, including a parallel run against your current workbook. Complex multi-entity or multi-currency setups take longer.
How much does a cash flow forecasting integration cost?
Focused builds that connect invoicing, banking and expenses into a rolling 13-week model typically range from R35,000 to R85,000 depending on the number of sources and alert rules. Most finance teams spending a day a week on manual rebuilds see payback within a few months on staff time alone.
Stop Flying Blind on Cash
If your financial projections still depend on a spreadsheet rebuild every week, you are making payroll and supplier decisions without a current cash position.
