The model is not the objective. It is a structured way to test assumptions, understand financial consequences and communicate a plan to the people making or assessing a decision. ### Build from operating drivers to connected outputs A useful model separates assumptions from calculations and outputs. Revenue may be driven by customer numbers, price, capacity or project timing. Costs may respond to activity, hiring, contracts or investment decisions. Where the purpose requires it, these drivers feed an integrated profit-and-loss, balance-sheet and cash-flow view. Scenario controls should allow users to test realistic changes without rewriting formulas. Outputs can then focus on the measures relevant to the decision, such as cash runway, funding requirement, debt repayment, covenant headroom, break-even point or return on investment. - Visible assumptions and source notes - Integrated financial statements where required - Scenario and sensitivity controls - Decision-focused summary outputs ### Model review and validation without audit terminology An existing model can be reviewed for structure, formula consistency, broken links, assumption clarity, scenario behaviour and usability. The scope should identify which areas are being checked and whether corrections, redesign or documentation are included. This work is described as model review or validation. It is not a statutory audit, model audit opinion or independent assurance engagement. The final handover can include an assumptions guide, output explanation and practical instructions for updating the model. ## Commercial outcomes ### Connected financial statements Profit and loss, balance sheet and cash flow can be integrated where the decision requires a complete financial view. ### Visible assumptions The drivers behind revenue, costs, funding and investment are separated from calculations and outputs. ### Decision-ready scenarios Management can test realistic changes and see their effect without rebuilding the model each time. ### Clearer communication Outputs are structured for the people using them, including management, lenders or investors. ## When this service makes sense - A startup or growing company needs credible projections for a business plan - Management wants to test pricing, hiring, investment or expansion options - A lender or investor requires an integrated financial view - An existing model has become unreliable, opaque or difficult to update ## How the engagement works We start with the decision, the operating drivers and the audience for the model. The structure is then built to connect assumptions with profit and loss, balance sheet and cash flow where appropriate. Existing models can also be reviewed, validated and improved so that management understands both their mechanics and their limitations. - **Purpose-led design:** Build only the detail required for the decision and intended users. - **Transparent logic:** Keep assumptions, calculations and outputs structured and explainable. - **Practical scenarios:** Make it straightforward to test the variables that matter most. ## The first working cycle 1. **Define the purpose:** Confirm the decision, intended users, required outputs and level of detail that will be useful. 2. **Gather and challenge assumptions:** Document the operating drivers, source information and areas of material uncertainty. 3. **Build, test and explain:** Construct the model, review its mechanics and provide outputs that users can understand and update. ## Information normally required - The decision or funding purpose the model must support - Historical financial information, where available - Commercial assumptions for revenue, costs and timing - Requirements supplied by lenders, investors or other intended users ## Ways to engage ### New financial model A purpose-built model for growth, funding, pricing, investment or another defined decision. ### Business-plan financials Integrated projections and presentation schedules aligned with the commercial plan. ### Model review and improvement A review of structure, logic and usability, followed by agreed corrections or improvements. ## Frequently asked questions ### Can you review a model we already use? Yes. Our team can review and validate its structure, logic and usability, then correct or improve the agreed areas. This is model review, not statutory audit or assurance. ### Will the model guarantee a funding outcome? No. A well-built model can make assumptions and funding requirements clearer, but a lender or investor makes its own decision and future performance remains uncertain. ### Can the model include different scenarios? Yes. Scenario and sensitivity analysis can show how selected changes affect performance, cash and funding needs. ## Related pages - [Cash-Flow, Budgeting & Forecasting](https://irishaccountingpartner.com/services/cash-flow-forecasting.md): Cash flow forecasting services plus budgeting and forecasting support for Irish businesses planning cash, resources, funding and performance. - [Virtual CFO & Outsourced Finance](https://irishaccountingpartner.com/services/virtual-cfo.md): Virtual and Fractional CFO services in Ireland, providing recurring finance leadership and decision support without a full-time CFO hire. - [Management Accounts & Performance Reporting](https://irishaccountingpartner.com/services/management-accounts.md): Management accounting services and performance reporting that explain results, highlight variance and give Irish businesses a clearer operating view. - [Fees and engagement options](https://irishaccountingpartner.com/fees.md): How scopes and fees are agreed. - [Contact Irish Accounting Partner](https://irishaccountingpartner.com/contact.md): Send an enquiry or call the team.
