A&A · BUSINESS & COMPLIANCE ADVISORY
Test the decision before you commit the capital.
THE STARTING POINT
A financial feasibility study tests whether a proposed business or investment can support its operating costs, funding requirements and expected return under stated assumptions. It is a decision model, not proof that a venture will succeed. A&A helps structure the inputs and compare realistic scenarios.
CLEAR OUTPUTS
Document price, volume, utilisation, staffing and cost inputs with their sources. Flag estimates that need validation before investment approval.
Connect profit and loss, working capital, capital expenditure and cash flow. Make funding timing visible rather than relying on accounting profit alone.
Compare base and downside cases, break-even drivers and funding headroom. Explain which assumptions change the decision and what further evidence is needed.
FROM QUESTION TO ACTION
Agree the investment alternatives, horizon, currency and decision criteria before building the model.
Review quotations, capacity constraints and commercial assumptions. Record where independent market research is outside scope.
Calculate the effect of slower sales, cost increases and collection delays. Keep assumptions editable and transparent.
Check sensitivity, cash shortfalls and practical constraints. Deliver a recommendation with conditions rather than false certainty.
MAKE THE DISTINCTION
| Workstream | Purpose | Important distinction |
|---|---|---|
| Accounting profit | Revenue less recognised costs | May not show cash collection delays |
| Cash flow | Timing of receipts and payments | Identifies funding gaps |
| Investment return | Cash outcomes against capital committed | Sensitive to horizon and assumptions |
PREPARE FOR THE REVIEW
The final checklist depends on your entity, purpose and agreed assignment. Begin with an inventory; share sensitive records only through an agreed secure channel.

AGREE THE BOUNDARIES
Forecasts are conditional estimates, not assured outcomes or financing approval. Any investment decision remains with management. Tax, legal, technical and independent market assessments should be separately scoped where needed.
QUESTIONS WORTH ASKING
No. A business plan covers a broader operating strategy. Financial feasibility focuses on the numerical viability, cash requirements and assumptions behind an investment decision.
Yes. Upfront expenditure, inventory and slow customer payments can create a funding gap even when projected accounting profit is positive.
Acceptance is the lender’s decision. Obtain its required format, assumptions and supporting evidence before commissioning work for a financing application.
Use explicit scenarios and sensitivity tests rather than a single optimistic forecast. Identify which assumptions need market validation and show the cash impact if sales develop more slowly.
