Financial Modelling

Too many spreadsheets are impressive to look at and impossible to rely on: assumptions buried in formulas, no way to flex the numbers, and a single error that quietly undermines every output. When you are raising money, pricing a deal or committing to a strategy, that is a serious risk. A well-built model does the opposite — it makes your assumptions explicit, lets you test them, and gives everyone confidence in the answer.

Acumon builds robust, transparent financial models to recognised best-practice standards, combining modelling discipline with real transaction and business-planning experience. The result is a model that supports the decision, survives scrutiny, and keeps working long after it is first built.

What We Model

Business planning and budgeting: integrated three-statement models — profit and loss, balance sheet and cash flow — that turn your strategy into numbers and show when cash is tight and when it is comfortable. Fundraising: models that stand up to investor and lender scrutiny, evidencing the returns, the funding requirement and the repayment or exit profile. M&A: acquisition, merger and buy-out models that test affordability, financing structures and the impact on returns. Strategy and options appraisal: comparing scenarios — a new site, a new product, a pricing change, a capital investment — on a like-for-like basis. And valuation-support models, including discounted cash flow, that underpin our valuation work.

Built to Best-Practice Standards

Every model we build follows the same disciplines: a clear separation of inputs, calculations and outputs; assumptions gathered in one place and clearly labelled, so anyone can see what is driving the numbers and change them safely; consistent, auditable formulas; and built-in checks that flag if the model stops balancing. That structure is what makes a model trustworthy — and what lets you keep using it as your business evolves, rather than rebuilding from scratch each year.

Sensitivity and Scenario Analysis

No forecast is certain, so we build in the tools to explore the uncertainty. Sensitivity analysis shows how the outputs move when a key assumption changes — what happens to cash if sales come in 10% below plan, or if a major cost rises. Scenario analysis compares complete alternative worlds — base case, upside, downside — side by side. This is where a model earns its keep: not in predicting a single future, but in showing you the range of outcomes, the points at which the plan breaks, and the levers that matter most.

Why Acumon

We combine modelling craft with the judgement that comes from advising on real transactions and running real businesses — including the firm's own acquisitions. That means our models reflect how deals and businesses actually behave, not just textbook mechanics. And because our modelling connects directly to our valuation, due diligence and business support services, the model you commission can flow straight into the next stage of your plan rather than sitting on a shelf.
