Cashflow forecasting is like having a weather forecast for your finances—except it tells you whether you’ll have a cash downpour or a drought. Get it right, and you avoid nasty surprises, seize growth opportunities, and sleep a little easier. Here’s your guide to what it is, why it matters, when to start, and how to nail it.
What Is Cashflow Forecasting?
Cashflow forecasting is the process of estimating how much cash will flow in and out of your business over a set period. It’s not just a spreadsheet full of numbers—it’s your financial GPS, showing:
- Expected cash receipts (sales, loan draws, equity injections)
- Projected outflows (rent, payroll, supplier payments, tax bills)
- Net cash position at future dates
With a proper forecast, you know when you’ll need extra funds or when you can reinvest in growth.
Why It Matters
Pitfalls You’ll Avoid
- Sudden Cash Shortages: Spot funding gaps before they become crises.
- Late Payments to Suppliers: Keep your reputation (and credit rating) intact.
- Rushed Borrowing Decisions: Secure finance on your terms, not when you’re desperate.
- Missed VAT and Tax Deadlines: Budget for liabilities so HMRC deadlines aren’t unpleasant surprises.
Opportunities You’ll Find
- Strategic Investments: Identify windows to hire, launch marketing campaigns, or expand premises.
- Better Supplier Terms: Pay early when you’re in surplus, and negotiate discounts.
- Optimised Funding Mix: Decide whether to tap an overdraft, invoice factoring, or reinvest profits.
- Investor Confidence: Present clear, data-backed plans that smooth fundraising conversations.
When to Start Planning
The best time to build a cashflow forecast was yesterday. The second-best time is today.
- New and Small SMEs: Kick off a simple rolling 3-month forecast as soon as you’ve invoiced your first customer.
- Growing SMEs: Adopt a 6- or 12-month outlook once sales volumes and expenses become more predictable.
- Seasonal Businesses: Layer on monthly or even weekly forecasts during peak and off-peak cycles.
Early adoption means you’re never caught off-guard by seasonal swings or one-off costs.
How to Build a Cashflow Forecast
- Choose Your Timeframe
- Short term: weekly, for tight cash-management
- Medium term: monthly, for VAT, payroll, and board reporting
- Long term: quarterly or annually, to plan major investments
- List All Cash Inflows
- Customer invoices (map each to its payment terms)
- Loan proceeds, grants, or equity injections
- Other income (asset disposals, refunds)
- Map All Cash Outflows
- Fixed costs: rent, salaries, subscriptions
- Variable costs: materials, marketing, utilities
- Irregular or seasonal spends: tax bills, insurance premiums
- Build Your Template
- Use cloud-based bookkeeping software or a simple spreadsheet
- Automate data pulls from your bank feeds and Debtor Watch ageing reports
- Colour-code inflows and outflows for clarity
- Monitor and Update
- Reconcile actuals weekly or monthly
- Compare forecast vs actual and investigate variances
- Adjust projections for new orders, delayed payments, or cost changes
Common Mistakes to Avoid
- Over-optimistic Sales: Base forecasts on signed contracts, not wishful thinking.
- Ignoring Timing Lags: Remember that invoices on Net 30 still hit your bank in 30 days, not on issue.
- Forgetting One-Off Expenses: Licence renewals, machinery servicing, or board bonuses can upset your forecast if overlooked.
- Stale Forecasts: An outdated model is as useful as a broken GPS—set review alarms in your calendar.
