Example session with this skill installed
Analyze this for my monthly report: Revenue £92k (Budget £105k). Travel £8k (Budget £3k). IT Support £2k (Budget £5k). Notes: Revenue hit by client delay. Travel high due to one-off NYC conference.

Processed variance analysis for the current reporting period.
Budget Variance Commentary
Reporting Context
- Period: Current Month
- Currency: GBP (£)
- Materiality Threshold: Applied to variances > 10% or £2,000.
Executive Summary
The overall position is adverse, primarily driven by a £13k revenue shortfall and a significant overspend in travel. These are partially offset by a small underspend in IT support, which appears to be a timing difference.
Variance Commentary Table
| Line Item | Actual | Budget | Variance | Var % | Direction | Draft Commentary |
|---|---|---|---|---|---|---|
| Revenue | £92,000 | £105,000 | (£13,000) | (12.4%) | Adverse | Revenue is below target due to delays in client project starts. |
| Travel | £8,000 | £3,000 | (£5,000) | 166.7% | Adverse | Significant overspend related to a one-off NYC conference attendance. |
| IT Support | £2,000 | £5,000 | £3,000 | 60.0% | Favourable | Underspend likely due to delayed billing or reduced ticket volume. |
Follow-Up Questions for Budget Holders
Revenue: Which specific clients delayed? Are these projects expected to commence next month or is this a permanent loss?
- Travel: Was the NYC conference unbudgeted, or was the cost significantly higher than the original estimate?
IT Support: Is this a permanent saving due to lower demand, or are we awaiting an invoice from the service provider?
Suggested Management Actions
- Revenue Forecast: Update the Q3 forecast to reflect the new project start dates.
Travel Policy: Review whether the NYC conference costs require retrospective approval if they exceeded the discretionary limit.
3.
Accrual Check: Confirm with IT if all support hours for the month have been billed to ensure this isn't a missing accrual.
Next steps
- Review the "Follow-Up Questions" with the Sales and IT leads.
- Incorporate the "Draft Commentary" into the monthly Board Pack.
- Verify if the travel overspend is a recurring trend or a strictly one-off event.

What you get
About this skill
Manual variance analysis is a bottleneck for finance teams and project managers. This skill automates the translation of raw actuals-versus-budget data into structured management commentary, identifying likely drivers and surfacing critical follow-up questions for budget holders.
What it does
- Narrative generation converts raw financial variances into plain-English summaries for board packs or management reports.
- Root cause hypothesis identifies likely drivers such as timing differences, volume changes, price fluctuations, or accrual issues.
- Materiality filtering focuses analysis on significant movements based on user-defined or calculated thresholds.
- Audit & review scans existing commentary for inconsistencies where the narrative does not match the numerical data.
- Actionable follow-ups generates specific questions for department heads to validate unexplained overspends or underspends.
How it works
- Context setting involves providing the reporting period, currency, and materiality threshold.
- Data ingestion processes line-item actuals, budgets, and any existing rough notes or explanations.
- Analysis & classification categorizes movements as favourable or adverse and flags potential data-quality issues.
- Drafting & review produces a structured commentary table, executive summary, and suggested management actions.
Frameworks & tools
This skill is designed for use within ChatGPT and works with data exported from ERP systems, accounting software like Xero or QuickBooks, and Excel-based budget trackers.
Why this beats prompting it yourself
Writing neutral, non-defensive financial commentary is difficult to prompt consistently. This skill enforces strict separation between confirmed facts and hypotheses, ensuring your reports remain professional and balanced without manual oversight of every line item.
Use cases
- Monthly management reporting to explain departmental performance to executives.
- Project budget tracking for identifying slippage or unplanned resource costs.
- Grant reporting for nonprofits needing to justify spend against restricted funding.
- Pre-close reviews to catch coding errors or missing accruals before finalising accounts.
Known limitations
Does not provide formal audit assurance, tax advice, or statutory accounting judgments. Users must provide the underlying financial figures as it cannot browse private internal databases.
