If turnover is rising but profit is flat, you don\u2019t have a sales problem. You have leakage.<\/span><\/p>\n

Most profit leaks are small on their own. Together, they can erase a strong month. The danger is that they get missed because you\u2019re \u201cbusy\u201d.<\/span><\/p>\n

This article shows how to identify\u00a0profit leaks in your limited company<\/strong>\u00a0using simple checks you can run each month.<\/span><\/p>\n

Start with the three questions that reveal leakage<\/strong><\/span><\/p>\n

Before you analyse anything, answer these:<\/span><\/p>\n

    \n
  1. \n

    Did we sell the right work, at the right price?<\/span><\/p>\n<\/li>\n

  2. \n

    Did we deliver it with the cost base we planned?<\/span><\/p>\n<\/li>\n

  3. \n

    Did we collect cash in line with terms?<\/span><\/p>\n<\/li>\n<\/ol>\n

    If you can\u2019t answer one of these quickly, that\u2019s your first leak: visibility.<\/span><\/p>\n

    Leak 1: Pricing and scope drift<\/strong><\/span><\/p>\n

    Scope creep is often the biggest leak in service businesses, and the hardest to see in accounts.<\/span><\/p>\n

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

      \n
    • \n

      Revenue is up, but gross margin is down.<\/span><\/p>\n<\/li>\n

    • \n

      Staff are \u201cflat out\u201d but output per person isn\u2019t improving.<\/span><\/p>\n<\/li>\n

    • \n

      Projects finish, but the invoice value doesn\u2019t match the effort.<\/span><\/p>\n<\/li>\n<\/ul>\n

      What to check:<\/strong><\/span><\/p>\n

        \n
      • \n

        Average selling price (ASP) this month vs last quarter<\/span><\/p>\n<\/li>\n

      • \n

        Discounting patterns (especially \u201cone-off\u201d discounts that repeat)<\/span><\/p>\n<\/li>\n

      • \n

        Change requests: are they priced, approved, and invoiced?<\/span><\/p>\n<\/li>\n<\/ul>\n

        Fix:<\/strong>
        Create a simple rule: any work outside the original scope needs one of three outcomes within 24 hours - priced, deferred, or rejected. No silent yeses.<\/span><\/p>\n

        Leak 2: Labour utilisation and delivery efficiency<\/strong><\/span><\/p>\n

        Labour is often your main cost lever. Even a small utilisation dip can wipe out margin.<\/span><\/p>\n

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

          \n
        • \n

          Wage cost grows faster than revenue.<\/span><\/p>\n<\/li>\n

        • \n

          Overtime increases without a matching increase in billing.<\/span><\/p>\n<\/li>\n

        • \n

          High \u201cinternal\u201d work that never becomes deliverable value.<\/span><\/p>\n<\/li>\n<\/ul>\n

          What to check:<\/strong><\/span><\/p>\n

            \n
          • \n

            Revenue per head (or per billable head) trend<\/span><\/p>\n<\/li>\n

          • \n

            Labour as a % of revenue<\/span><\/p>\n<\/li>\n

          • \n

            Rework: how often tasks are done twice<\/span><\/p>\n<\/li>\n<\/ul>\n

            You don\u2019t need complex time tracking to start. A weekly \u201ccapacity and output\u201d snapshot (planned hours vs delivered output) will surface gaps.<\/span><\/p>\n

            Fix:<\/strong>
            Pick one operational metric and stick to it for 90 days. For many firms: \u201cbillable utilisation\u201d for delivery teams, or \u201cjobs completed per week\u201d for trade\/ops teams.<\/span><\/p>\n

            Leak 3: Subcontractors, materials, and purchased services<\/strong><\/span><\/p>\n

            Subcontractors and external spend often creep because they feel variable and \u201cnecessary\u201d.<\/span><\/p>\n

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

              \n
            • \n

              Subcontractor costs rise even when pipeline is stable.<\/span><\/p>\n<\/li>\n

            • \n

              Materials costs vary, but pricing stays fixed.<\/span><\/p>\n<\/li>\n

            • \n

              Tools and software stack grows, but no one owns it.<\/span><\/p>\n<\/li>\n<\/ul>\n

              What to check:<\/strong><\/span><\/p>\n

                \n
              • \n

                Gross margin by job type \/ client<\/span><\/p>\n<\/li>\n

              • \n

                Top 10 suppliers: spend this month vs average<\/span><\/p>\n<\/li>\n

              • \n

                Recurring subscriptions: count and total monthly cost<\/span><\/p>\n<\/li>\n<\/ul>\n

                Fix:<\/strong>
                Assign ownership to every recurring cost. If nobody owns it, it gets cut or justified.<\/span><\/p>\n

                Leak 4: Overheads that grew quietly<\/strong><\/span><\/p>\n

                Overheads don\u2019t usually explode. They drift.<\/span><\/p>\n

                Examples:<\/span><\/p>\n

                  \n
                • \n

                  Extra systems and licences<\/span><\/p>\n<\/li>\n

                • \n

                  Delivery travel and small claims<\/span><\/p>\n<\/li>\n

                • \n

                  \u201cTemporary\u201d services that became permanent<\/span><\/p>\n<\/li>\n

                • \n

                  Office costs that stayed after working arrangement changes<\/span><\/p>\n<\/li>\n<\/ul>\n

                  What to check:<\/strong><\/span><\/p>\n

                    \n
                  • \n

                    Overheads as a % of revenue (trend)<\/span><\/p>\n<\/li>\n

                  • \n

                    \u201cOther\u201d expense lines (always a warning)<\/span><\/p>\n<\/li>\n

                  • \n

                    Any category up more than 10\u201315% over the last quarter<\/span><\/p>\n<\/li>\n<\/ul>\n

                    Fix:<\/strong>
                    Run a quarterly overhead reset. A planned review: keep, renegotiate, or remove.<\/span><\/p>\n

                    Leak 5: Poor cash discipline that creates hidden cost<\/strong><\/span><\/p>\n

                    Cash leaks don\u2019t just reduce bank balance. They create indirect cost: stress, rushed decisions, and expensive short-term fixes.<\/span><\/p>\n

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

                      \n
                    • \n

                      Debtors regularly exceed terms.<\/span><\/p>\n<\/li>\n

                    • \n

                      You\u2019re paying suppliers early but collecting late.<\/span><\/p>\n<\/li>\n

                    • \n

                      VAT\/PAYE deadlines cause sudden squeezes (UK) or tax payments surprise you (anywhere).<\/span><\/p>\n<\/li>\n<\/ul>\n

                      What to check:<\/strong><\/span><\/p>\n

                        \n
                      • \n

                        Aged receivables: 30\/60\/90+<\/span><\/p>\n<\/li>\n

                      • \n

                        Payment terms on invoices vs actual days to pay<\/span><\/p>\n<\/li>\n<\/ul>\n

                        Fix:<\/strong>
                        Separate \u201cinvoicing\u201d from \u201ccollections\u201d. Invoicing is a bookkeeping activity. Collections is revenue protection. Make it someone\u2019s weekly responsibility with a clear communication structure and escalation path.<\/span><\/p>\n

                        Quick wins<\/strong><\/span><\/p>\n

                          \n
                        • \n

                          Add a monthly\u00a0gross margin bridge<\/strong>: what changed and why.<\/span><\/p>\n<\/li>\n

                        • \n

                          Identify your\u00a0top 10 customers<\/strong>\u00a0by profit, not revenue.<\/span><\/p>\n<\/li>\n

                        • \n

                          Cap discounting: any discount above a set % needs approval.<\/span><\/p>\n<\/li>\n

                        • \n

                          Review recurring costs: cancel anything without an owner.<\/span><\/p>\n<\/li>\n

                        • \n

                          Tighten collections: chase at 7, 14, and 21 days (or before due, if you can).<\/span><\/p>\n<\/li>\n<\/ul>\n

                          Conclusion<\/strong><\/span><\/p>\n

                          Profit leaks are rarely dramatic. They\u2019re operational habits that went unmeasured: scope drift, weak utilisation, supplier creep, and slow collections.<\/span><\/p>\n

                          Put a simple monthly review in place and you\u2019ll see the leaks quickly, and fix them without turning finance into a full-time job.<\/span><\/p>\n
