Xero Cash Flow Forecast: A Complete Guide for UK Businesses

A cash flow forecast tells you whether your business will have enough money to pay its bills next month, next quarter, or next year. It’s the difference between planning ahead and being able to plan for the future and scrambling to cover payroll because a big client paid late.

This guide explains how cash flow forecasting works in Xero, which tools are available, and how to build a forecast that actually helps you make better decisions.

What Is a Cash Flow Forecast?

A cash flow forecast is an estimate of money coming in and going out of your business over a future period. It’s different from your profit and loss report – the P&L shows whether you’re making money, but the numbers show whether you’ll have the cash to operate day to day.

Think of it this way: you might have £50,000 in outstanding bills, but if none of those customers pay this month and you owe £30,000 to suppliers next week, your cash position is a problem regardless of what the P&L says.

A good forecast helps you spot these timing mismatches before they become emergencies.

How Xero Handles Cash Flow Forecasting

The Xero dashboard

When you log into Xero, the dashboard shows a basic cash flow graph – money in versus money out over the past 30 days. It also shows your current bank balance, what customers owe you, and what you owe suppliers. This is a snapshot, not a forecast, but it gives you a starting point.

Xero’s short-term cash flow view

Analytics Plus (available on the Grow plan at £37/month) adds a short-term cash flow view that looks 30 days ahead. It pulls data from your account automatically:

  • Unpaid customer invoices and their due dates
  • Unpaid supplier bills and when they’re due
  • Repeating transactions (rent, subscriptions, salaries)
  • Current bank balances across all connected accounts

The projection shows your expected cash position day by day for the next month. If the line drops below zero, you know a shortfall is coming.

Cash flow statement

Xero also generates a cash flow statement (statement of cash flows) showing how cash moved through your business in a past period. It breaks activity into operating cash flow, investing activities, and financing activities. Your accountant uses this for year-end accounts. The free cash flow (net cash from operations) figure – operating cash flow minus capital expenditure – tells you how much cash the business generates on its own.

Cash Flow Planning Apps That Works With Xero

For forecasts longer than 30 days, you need a dedicated cash flow forecasting software from the Xero App Store. These planning apps connect to your Xero account and the the app store. These connect to your data and build rolling projections automatically.

Float

Float is the most widely used cashflow forecasting and planning software, an accounting software add-on for small businesses in the UK. It syncs with your account and creates a visual cash flow timeline stretching 3, 6, or 12 months ahead.

What makes Float useful is scenario modelling. You can ask “what happens to my cash flow if this client pays 60 days late instead of 30?” or “can I afford to hire someone next quarter?” Float shows the forecast impact instantly. It costs around £50/month.

Cash Flow Frog

A newer alternative to Float, Cash Flow Frog offers AI-powered cashflow planning that analyses your data patterns to predict future cash inflows and outflows. It’s simpler than Float and cheaper (from £29/month), making it a good option for very small businesses that want forecasting without complexity.

Futrli

Futrli combines cash flow forecasting with business planning and KPI dashboards. It’s more powerful than Float for scenario planning and financial modelling, but also more complex. Best suited to businesses that present forecasts to investors, banks, or boards.

Spotlight Reporting

A management reporting platform with planning features. Spotlight is popular with accounting firms that manage cash flow forecasts for multiple clients through Xero. It produces board-ready financial reports and consolidations.

How to Build a Cash Flow Plan From Xero Data

Even without planning apps, you can build a practical forecast using the platform reports and a spreadsheet:

Step 1: Start with your cash position

Check your bank balance on the Xero cash flow dashboard. This is your starting point.

Step 2: Estimate cash inflows

Run the Aged Receivables report in Xero. This shows what customers owe you and when it’s due. But don’t assume everyone pays on time – adjust for your actual collection patterns. If your average debtor days are 45, plan accordingly.

Add any recurring revenue (subscriptions, retainers) and expected new sales.

Step 3: Estimate cash outflows

Run the Aged Payables report for supplier bills due. Add fixed commitments: rent, salaries, loan repayments, insurance, and software subscriptions. Don’t forget quarterly obligations like VAT payments and annual costs like corporation tax.

Step 4: Calculate your future cash position

Cash position = starting balance + expected inflows – expected outflows. Do this for each week or month and you have a rolling cash flow plan.

Step 5: Review and update

The process is only useful if you update it regularly. Monthly updates are the minimum for most small businesses. Weekly is better if cash is tight.

What a Cash Flow Forecast Helps You Do

A cash flow forecast helps you make decisions with confidence rather than guesswork:

  • Chase invoices strategically – your plan shows which late payments will cause the most damage. Focus collection efforts there.
  • Time major purchases – can you afford new equipment this month or should you wait until after the next big payment arrives?
  • Negotiate with suppliers – if the numbers show a tight month, ask for extended payment terms before the crunch hits.
  • Plan hiring – adding a salary to your outflows. The numbers show whether you can sustain it for 6-12 months.
  • Apply for finance – banks want to see a cash flow plan when you request a loan or overdraft facility. It proves you understand your cash flow management needs.

Cash Flow Plan vs Budget vs P&L

These three reports answer different questions:

  • P&L – “Am I making money?” Based on when you earn and incur costs (accruals basis).
  • Budget – “Am I spending what I planned?” Set targets and compare actuals. Built in Xero via Budget Manager.
  • Cash flow forecast – “Will I have enough cash?” Based on when money actually arrives and leaves your bank account.

A business can be profitable, on budget, and still run out of cash. That’s why this matters separately from the other two.

Planning for Seasonal Businesses

Retailers, hospitality, tourism, and construction businesses all have seasonal cash flow patterns. Your forecast needs to reflect this:

  • Look at last year’s your data for the same months to establish your seasonal baseline
  • Build reserves during peak months to cover quiet periods
  • Plan major purchases for your cash-rich season, not the lean months
  • If you use Float, it can automatically detect seasonal patterns from your your data and adjust projections accordingly

Common Planning Mistakes

  • Assuming customers pay on time – they often don’t. Use actual payment history from your the Aged Receivables report, not the terms on the invoice.
  • Forgetting tax – VAT, corporation tax, and PAYE are large cash outflows. Plan for them specifically.
  • Not updating regularly – a three-month-old forecast is fiction. Update monthly at minimum.
  • Confusing profit with cash – a profitable business with £100,000 in unpaid invoices can still fail if it can’t meet this week’s payroll.
  • Single scenario thinking – build a base case, an optimistic case, and a pessimistic case. Reality usually lands somewhere between them.

Xero Getting Started With Cash Flow Planning

If you’re new to cash flow planning with Xero, here’s where to start:

  1. Get your Xero data up to date – reconcile your bank accounts, enter all outstanding bills and bills. The plan is only as good as the data behind it.
  2. Run your Aged Receivables and Aged Payables reports – these show your current cash flow commitments.
  3. Try the built-in projection – if you’re on the Grow plan, check Analytics Plus for the 30-day cash flow view.
  4. Consider Float – for a proper 12-month rolling plan with scenario modelling. There’s a free trial on the the app store.
  5. Talk to your advisor – your accountant can help interpret the results and suggest actions to improve your cash position.

Frequently Asked Questions

Does Xero have built-in cash flow forecasting software?

Xero Analytics Plus includes a short-term cash flow projection (30 days). For longer cash flow projections and scenario modelling, connect Float or Futrli from the app store.

Is there a free cash flow forecast template for Xero?

Float offers a free trial that connects to your Xero account and generates a cash flow forecast automatically. Xero itself does not provide a standalone template, but the Analytics Plus dashboard gives you a visual cash flow view at no extra cost on the Grow plan.

How far ahead should I forecast?

Most small businesses benefit from a 3-month rolling forecast. Seasonal businesses should forecast 12 months to capture full annual cycles. The further out you go, the less accurate the numbers – but even a rough 12-month plan for the future is better than none.
