Profit is an opinion until cash arrives.<\/span><\/p>\n

If you\u2019re hiring, scaling delivery, or taking on bigger projects, cash timing becomes the constraint. A strong order book can still create a cash crunch.<\/span><\/p>\n

Cash flow forecasting for limited companies<\/span><\/strong>\u00a0doesn\u2019t need a complex model. You need a repeatable process that is accurate enough to support decisions.<\/span><\/p>\n

\n

The only forecast that matters: the next 13 weeks<\/span><\/h2>\n

Annual cash forecasts look great but they get ignored. A rolling 13 week forecast stays close to reality and highlights problems early.<\/span><\/p>\n

Why 13 weeks?<\/span><\/p>\n

    \n
  • \n

    It covers a full quarter of payroll cycles and supplier payments.<\/span><\/p>\n<\/li>\n

  • \n

    It\u2019s long enough to spot a cash flow squeeze before it hits.<\/span><\/p>\n<\/li>\n

  • \n

    It\u2019s short enough that you can keep it current.<\/span><\/p>\n<\/li>\n<\/ul>\n

    The goal here is visibility and control.<\/span><\/p>\n

    \n

    Build the forecast in three steps<\/span><\/h2>\n

    Keep your structure simple so that you can still keep close to the cash in busy periods.<\/span><\/p>\n

    \n

    Step 1: Starting cash<\/span><\/h3>\n

    Use actual bank balances (all accounts).<\/span><\/p>\n

    \n

    Step 2: Known committed outflows<\/span><\/h3>\n

    These are the payments that will happen unless you actively stop them:<\/span><\/p>\n

      \n
    • \n

      Payroll (net pay + employer costs + any payroll taxes)<\/span><\/p>\n<\/li>\n

    • \n

      Rent, finance, insurance, key subscriptions<\/span><\/p>\n<\/li>\n

    • \n

      VAT\/PAYE in the UK, or equivalent periodic taxes elsewhere<\/span><\/p>\n<\/li>\n

    • \n

      Loan repayments<\/span><\/p>\n<\/li>\n<\/ul>\n

      Put dates on them. Cash is about timing, not categories.<\/span><\/p>\n

      \n

      Step 3: Expected inflows and variable outflows<\/span><\/h3>\n

      This is where judgement enters, so make the assumptions visible.<\/span><\/p>\n

      Inflows:<\/span><\/strong><\/p>\n

        \n
      • \n

        Invoices already issued: use expected payment dates based on customer behaviour, rather than invoice terms<\/span><\/p>\n<\/li>\n

      • \n

        Pipeline receipts: only include what is genuinely likely, and note the basis<\/span><\/p>\n<\/li>\n<\/ul>\n

        Variable outflows:<\/span><\/strong><\/p>\n

          \n
        • \n

          Subcontractors and materials tied to specific jobs<\/span><\/p>\n<\/li>\n

        • \n

          Large one-off purchases<\/span><\/p>\n<\/li>\n

        • \n

          Planned hires (start date and total monthly cash outflow)<\/span><\/p>\n<\/li>\n<\/ul>\n

          \n

          A weekly 30-minute routine that keeps it useful<\/span><\/h2>\n

          Forecasts often don\u2019t work because they become \u201ca finance task\u201d. Make it a leadership habit instead.<\/span><\/p>\n

          Weekly routine (same day each week):<\/span><\/strong><\/p>\n

            \n
          1. \n

            Update starting cash from bank.<\/span><\/p>\n<\/li>\n

          2. \n

            Mark receipts as paid or late. Move late items forward.<\/span><\/p>\n<\/li>\n

          3. \n

            Update the next two weeks\u2019 expected receipts (based on communication with your customers and expected patterns).<\/span><\/p>\n<\/li>\n

          4. \n

            Add any new committed costs (purchase orders, hires, deposits).<\/span><\/p>\n<\/li>\n

          5. \n

            Review the lowest cash point in the next 13 weeks and decide actions.<\/span><\/p>\n<\/li>\n<\/ol>\n

            That\u2019s it.<\/span><\/p>\n

            \n

            How to improve accuracy quickly<\/span><\/h2>\n

            To create an accurate forecast, you don\u2019t need to add complexity, simply tighten the inputs.<\/span><\/p>\n

            Use customer payment behaviour<\/span><\/h3>\n

            If a customer usually pays in 45 days, set 45 days. Don\u2019t pretend it\u2019s 14 because the invoice says so.<\/span><\/p>\n

            Separate \u201cwill invoice\u201d from \u201cwill collect\u201d<\/span><\/h3>\n

            A signed project isn\u2019t cash. A sent invoice isn\u2019t cash. Cash is when it hits the bank account.<\/span><\/p>\n

            Keep \u201cpossible\u201d payments out of decision-making.<\/span><\/p>\n

            Treat tax as a planned cost<\/span><\/h3>\n

            Many limited company owners feel a cash squeeze because tax accrual isn\u2019t separated from operational cash. Tax timing can be chunky. Add taxes as explicit lines with expected payment dates.<\/span><\/p>\n

            \n

            What decisions a good forecast supports<\/span><\/h2>\n

                \n

                Conclusion<\/span><\/h2>\n

                Cash forecasting is a discipline. A rolling 13-week view, updated weekly, gives you control over timing, risk, and growth.<\/span><\/p>\n
