UK / FINANCIAL MODELLING & CASH FLOW

Financial Modelling and Cash Flow Forecasting

Explore hiring, investment and growth decisions with a model built around your business assumptions. TaxSpex can prepare cash-flow and working-capital forecasts, integrated financial models and scenario analysis to help you examine possible outcomes. The model reflects the assumptions and data agreed for the engagement; forecasts are estimates, not guarantees.

What financial modelling can include

  • Cash-flow and working-capital forecasts
  • Integrated profit and loss, balance sheet and cash-flow models
  • Scenario and sensitivity analysis
  • An assumptions register and handover walkthrough
  • A time horizon and update frequency agreed for the model

Who this service is for

This service may suit a business considering hiring, investment, expansion, funding or a change in working capital. It can also help an owner understand how changes to revenue, costs or timing could affect a plan. We agree the model’s purpose before deciding which outputs and scenarios are useful.

How the work proceeds

  1. 1
    Define the decision

    We agree the question the model should help explore, the intended users, time horizon and update frequency.

  2. 2
    Build the assumptions and model

    We document the agreed data sources and assumptions and prepare the forecast or integrated model. Scenario and sensitivity analysis are included where specified.

  3. 3
    Review and hand over

    We walk through the model structure, assumptions and outputs so you understand how to use and update it within the agreed scope.

Important boundaries

Forecasts are estimates based on assumptions and available information; actual results may differ. The work is business-planning support, not regulated investment advice. We do not guarantee funding, growth, profitability or a particular cash position.

YOUR STARTING POINT

What to have ready

Prepare recent management accounts, operating assumptions, debt schedules and a clear description of the decisions the model should support. We may ask about sales drivers, cost timing, financing and planned changes. The model’s usefulness depends on the quality and relevance of the source information.

Fees quoted in GBP. Scope, VAT treatment, software costs and any statutory fees are confirmed in writing.
