What to prepare

  • Gather supplier quotes, invoices, time records and the actual scope of the job or business decision.
  • Separate revenue from VAT, direct costs from overheads, and profit from the timing of cash receipts.
  • Use the same accounting period and currency for related inputs.

How to interpret the result

A profitable estimate can still create a cash shortfall. Read the cost and timing assumptions as well as the headline profit, price or return; the result is a scenario, not a sales forecast.

Keep the scope constant while changing price, volume, supplier cost or time. A lower-sales or higher-cost case helps show whether the decision depends on an optimistic assumption.

Common mistakes to avoid

  • Do not confuse markup on cost with margin on selling price.
  • Include work that is easy to miss, such as travel, setup, rework and administration, where the model supports it.
  • Do not treat tax collected or an unpaid invoice as freely available cash.
