Financial Model Reviews and Audits
Wiseworth provides independent financial model reviews for Australian businesses at every stage, from pre-seed through to pre-IPO and across every sector. If a model needs to be right before it reaches an investor, a lender, or a board, the review is the right first step.
BEFORE YOUR MODEL REACHES AN INVESTOR
The financial model review exists because of a simple and consistent pattern: the errors in a financial model are almost never found by the person who built it. They are found by the investor during due diligence, by the bank's credit analyst reviewing the lending application, by the board member who notices the balance sheet does not reconcile, or by the buyer's team who builds their own model from the target's P&L and gets different numbers.
Every one of these discovery events is worse than finding the error yourself. A model error found during due diligence damages the management team's credibility. A model error found by a lender delays, and sometimes derails, a credit decision. A model error found by a board member raises questions about the quality of the financial management. A model error found by a buyer's team raises questions about the quality of everything else in the data room.
The review finds them first.
SEVEN-DIMENSION AUDIT FRAMEWORK
1. Structural Architecture
Is the model structured to SMART Standard principles? Are inputs, calculations, and outputs separated? Does information flow in one direction? Are formulas consistent across rows and columns?
2. Formula Integrity
Does every formula do what it appears to do? Are there hardcoded numbers embedded in formulas that should be referenced from the assumptions sheet? Are there circular references, and if so, are they resolved correctly?
3. Three-Way Integration
Does the balance sheet balance in every period? Does the cash flow statement correctly capture working capital movements? Does the closing cash on the cash flow statement equal the cash on the balance sheet?
4. Assumption Quality
Are the key assumptions commercially reasonable and internally consistent? Are they clearly labelled and documented? Are the most sensitive assumptions tested through scenario analysis?
5. Scenario Design
Is the downside case genuinely adverse, or a cosmetically adjusted base case? Does the scenario manager work correctly, switching between scenarios with a single input and updating all three statements?
6. Presentation and Usability
Can a competent financial reviewer navigate the model without assistance? Is the summary dashboard clearly laid out? Are the key metrics presented in a format suitable for the intended audience?
7. Model Documentation
Are assumptions documented with their basis? Are any external data sources referenced? Can someone unfamiliar with the model understand its structure and purpose?
WHAT THE REVIEW PRODUCES
A written findings report identifying every issue by dimension, severity, and corrective action.
A corrected version of the model with all structural and formula errors fixed.
A verbal debrief with the management team covering the findings and the corrections.
Recommendations for improving the model's presentation for the specific audience.
WHAT HAPPENS AFTER THE REVIEW
The review produces a findings report and a corrected model. What happens next depends on what the review finds.
When the review identifies issues that can be corrected within the existing model structure, formula errors, hardcoded assumptions, presentation gaps, the corrected model is delivered as part of the engagement and the business can proceed with confidence. Most reviews fall into this category.
When the review identifies structural problems that cannot be corrected without rebuilding, a model where the three statements are not genuinely integrated, where the cash flow statement does not correctly capture working capital movements, or where the scenario manager does not function correctly, the corrected model is not fit for purpose with sophisticated audiences. In these cases the right outcome is a rebuild of the integrated model from the ground up, using the correct architectural principles from the start. This is a more significant engagement, but it is the only path to a model that will hold up under due diligence.
Where the structure is sound but the assumptions have not been stress-tested, the immediate next step is typically scenario modelling and sensitivity testing, adding a properly constructed downside case, an upside case, and a two-way sensitivity table to the existing model. Investors and lenders expect to see this. A model that presents only a base case is a model that has not been tested.
Where the review reveals that the model was built by a capable internal finance team who would benefit from building more robust models going forward, many clients follow the review with Excel financial modelling training for the relevant team members, covering SMART Standard principles, three-way integration, and scenario design so that future models are built correctly from the outset rather than reviewed and corrected after the fact.

FAQ
How much does a financial model review cost?
Pricing depends on model size and whether the review surfaces issues that need a rebuild versus a correction.
What is included in a financial model review?
A written findings report by dimension and severity, a corrected version of the model with formula and structural errors fixed, a verbal debrief, and presentation recommendations for your specific audience.
What if the review finds the model needs a full rebuild?
You will know exactly why, in writing, before any further work is scoped. A rebuild is a separate, clearly costed engagement, never an automatic upsell.
Who is a model review for?
Anyone about to put a model in front of an investor, lender, board, or buyer's due diligence team, and any finance team that built a model in-house and wants an independent second opinion.
