Turn budget files into a weekly variance brief

Overview

Computer uses a weekly automation to review budget files, actual spending, and finance notes, helping Finance stay ahead of overruns. Each review compares spending with the previous week, separates new issues from known exceptions, and produces a short brief with questions for budget owners.

Time to first result: At the next scheduled Monday review; request an immediate run for a first example.

Difficulty: needs setup

What you need

• Microsoft 365 connected, so Computer can read the budget workbook, actual-spend tracker, and finance notes in SharePoint.
• An actual-spend tracker for the review period; connect Snowflake for a live warehouse source, or provide a current export.
• Finance notes with budget owners and explanations for prior exceptions, so follow-up questions reflect what is already known.
• The previous review, so Computer can identify new, worsening, cleared, and unchanged issues; without one, the first brief establishes a baseline.
• A materiality threshold, such as 5% or $100,000, so the brief focuses on variances that warrant review.

What you get back

Weekly budget variance brief

Excerpt from the demo output: Questions for budget owners

Do you expect any additional Q4 prepays in September? If so, please add them to the reforecast.

What's your revised Q3 landing estimate, and does the Q4 budget still hold?

Should we open a dedicated project code, or continue booking to G&A?

Open the example brief and original task. The example uses fictional company data and illustrative figures.

• Headline summary: The overall spending position and the issues requiring attention before the next forecast.
• Variance table: Budget, actual spend, dollar and percentage variance, owner, and status across eight cost centres.
• Week-over-week review: New issues, worsening exceptions, cleared items, and previously explained variances.
• Owner questions: Specific follow-ups grouped by budget owner, with a reply-by date.
• Recommended actions: Proposed forecast changes, spending reviews, and watchlist updates for Finance to approve.

Delivered as a short written brief to review with Finance and use to prepare budget-owner follow-ups; the next scheduled review compares against the previous brief.

Make it better

• Add context: Include the last review and owner responses so resolved issues do not become new questions.
• Connect more: Add Snowflake to use warehouse actuals instead of a manually refreshed tracker.
• Point at specifics: Name the files, reporting period, and variance threshold so the comparison uses a consistent basis.
• Ask for the format: Specify a one-page brief with a variance table and questions grouped by owner.
• Make it recurring: Schedule the review before the weekly finance meeting and retain each brief for the next comparison.

Try a variation

• Review [Marketing's budget, actuals, and finance notes] against [last week's brief] and create a one-page brief on new overruns and questions for [the Marketing budget owner].
• Compare [this month's budget and actuals] with [last month's review] and create a spreadsheet of material variances, explanations, owners, and open questions.
• Review [the budget workbook], [actual-spend tracker], and [owner responses] and create a two-slide leadership update on new risks and decisions needed before [the forecast lock].

Related use cases
