Remember in 30 seconds

Modernising finance starts with verified data, clear responsibilities and tests on a limited process. Benefits are measured for each business; AI does not replace the review of sources and results.

The CFO's role changes when the company changes its data sources, tools or organisation. The priority stays the same: make the figures reliable and explain what they mean for decisions. For the responsibilities of the role, see the profession of CFO. This guide addresses developments in practices, without presuming a saving of time or a universal distribution of work.

1. Evaluate what is changing in financial work

A closing, a budget and a management meeting do not use the same data. Before modernising the function, observe how information is produced, corrected and validated. Re-entries, missing parts and unexplained discrepancies are different problems. They are not all solved by software.

It is not possible to deduct the time freed up by digitalisation from the job title. A useful measure relates to a defined task, over a comparable period, including corrections and review. A result obtained in a company does not automatically describe the market.

Management must also specify what remains in the team and what can be entrusted to a stakeholder. The guide Fractional CFO or interim distinguishes between engagement formats. Changing how the work is delivered does not excuse you from assigning decisions and approval authority.

2. Linking data, arbitrations and responsibilities

The first job is defining the data: periods, sources, calculation rules and owners. A margin indicator is only useful if you know which costs it covers. A cash balance says nothing about spending already committed. The CFO organises this reading with the people who know the operations.

The second project is the preparation of arbitrations. The reporting must make it possible to discuss recruitment, an investment, an expense or a financing deadline. Present the assumptions and their effects on cash, results and schedule. A forecast is used to discuss scenarios; it does not guarantee their achievement.

The third project is the allocation of responsibilities. Producing a file, verifying an entry, presenting an analysis and authorising a payment are distinct actions. Define access, controls and authorised people. The management control provides a reading of the discrepancies, while the decision rests with the agreed responsible parties.

3. Digitise a flow before extending the system

Choose a limited flow: collection of documents, reconciliation, updating of a forecast or distribution of a report. Compare the data produced with a reference source. Also test for a missing part, a duplicate and a period correction. These exceptions allow you to see if the team can actually exploit the system.

In Power BI, refreshing depends on the sources and the model used. The Microsoft documentation on data refresh explains these mechanisms. For financial management, above all specify the date of the last update and the action to take in the event of failure.

The guide choose and integrate financial tools presents the selection controls. Thedirectory of financial tools supplements this method with criteria specific to the products. A demonstration must cover your file and the functions included in the quote.

4. Supervising AI in financial production

An assistant can help prepare a summary, classify information or offer an initial analysis. The result must be able to be reconciled with the sources. Calculations, dates and references must remain verifiable; a convincing formulation is not proof of accuracy.

Start with limited use with authorised data and a review manager. Define what can be transmitted to the supplier, the storage conditions and access. THE questions and answers from the CNIL on generative AI help assess personal data risks. The choices must be validated for the organisation's own context.

The guide AI and automation of financial management distinguishes between uses and controls. To measure a pilot, record preparation time, corrections and review on a constant scope. Only announce a client result with its period, measurement method and the client's consent to publish.

5. Prepare relevant extra-financial data

Requests from customers, financiers or partners may relate to extra-financial data. First identify the requests that are really applicable to the company, with the competent contacts. A list of indicators found online is not enough to define an obligation or a calculation method.

For each data retained, document the scope, the source and the person who validates it. Separate measured information, estimates and unavailable items. Keep supporting documents and explain method changes between two periods. The CFO can coordinate this work without replacing technical or legal specialists.

6. Make reporting a decision support

A financial meeting should result in a few decisions attributed to managers. Present the deviations that require action, their known causes and the hypotheses that are still uncertain. Agree on the next review and what information to obtain before deciding.

Useful communication separates actuals, forecasts and recommendations. Rising revenue alone does not explain a change in cash. A funding round is not an improvement in profitability. The analysis must connect these dimensions without turning a correlation into an engagement result.

To rework the set-up, review the responsibilities and timetable in organise your finance function. A Fractional CFO can contribute to this work within an agreed scope. The data, the team available and the decisions expected shape the engagement.
