How to Use Microsoft Copilot for Finance: A CFO's Practical Guide

Finance teams spend more time in Excel than any other application. Copilot in Excel provides two categories of value: analysis support (answering questions about financial data) and model development support (helping build and validate financial models).

For CFOs reviewing management accounts or financial analysis: 'Which business units are tracking below budget, and what is the primary driver of the variance in each?' or 'Show me the trend in working capital metrics over the past eight quarters' produce immediate analytical outputs from data in the spreadsheet.

For model development: 'Add a sensitivity table showing the impact of a 10%, 20%, and 30% revenue shortfall on EBITDA and free cash flow' or 'Add a formula that calculates the debt service coverage ratio given the debt schedule and operating cash flow in columns C and D.'

For model validation: 'Review the assumptions in this financial model. Are there any formulas that appear to be inconsistent with the stated assumptions? Are there any inputs that are hardcoded when they should be variable?'

Management account preparation and board pack production are among the most time-consuming recurring tasks in any finance function. Copilot can significantly accelerate both.

For management commentary: 'Here are this month's management accounts and the corresponding prior year and budget figures. Draft the management commentary for the CFO report, covering: revenue performance, margin development, cost movements, and cash position. Tone: formal, precise, objective. Highlight the three most significant variances and provide the explanations management has given.'

For board pack production in PowerPoint: use Copilot to generate a first-draft finance section from the management accounts, then refine for board audience: 'Convert this financial data summary into three slides for the board pack: headline performance, key variances with explanations, and outlook.'

For the board narrative: 'Draft the CFO narrative for the board pack, based on the financial data I have shared. Cover: how we are performing versus plan, what is driving the main variances, and what the outlook is for the remainder of the year. Length: maximum one page. Tone: direct, honest, board-appropriate.'

For budgeting, forecasting, and scenario analysis, AI can accelerate the scenario modelling and documentation processes.

For scenario development: 'I am building three economic scenarios for our 2026 planning process: base, downside, and severe downside. For the [sector] sector, what are the macroeconomic assumptions typically used for each scenario in UK planning processes? What would be the key differences in revenue, cost, and financing assumptions between each scenario?'

For documenting modelling assumptions: 'Here are the assumptions in our budget model. Draft an assumptions document that explains the rationale for each key assumption, suitable for review by the audit committee.'

For stress testing: 'Based on the financial model I have shared, identify the three assumptions that, if wrong, would have the most material impact on our financial position. What would the impact be, and at what threshold would each assumption create a liquidity concern?'

For finance teams preparing for external audit, Copilot can accelerate the preparation of audit workpapers and the synthesis of responses to auditor queries.

For audit workpaper narratives: 'Draft the narrative explanation for this audit workpaper, which supports the [specific accounting policy or estimate]. The key judgements we have made are [list judgements]. The evidence supporting each judgement is [list evidence].'

For responding to auditor queries: 'Here is an auditor query about [issue]. Based on the documentation I have shared, draft a response that addresses each element of the query with specific reference to the supporting evidence.'

Audit-related documents require careful review before submission: accuracy and completeness are legal matters in audit contexts. Use AI to draft; have qualified finance professionals review and approve before submitting to auditors.
