Budget Variance Analysis Agent
Calculate plan/actual variances, identify causes, create commentary draft.
Merges plan and actual data, calculates variances by price, volume, mix and timing, identifies causes via AI analysis and creates a commentary draft for management reporting.

What This Agent Does
Budget variance analysis is the bridge between planning and reality. Every month, controlling must merge plan and actual data, calculate variances, identify causes and write a commentary for management. For a group with dozens of cost centres and hundreds of accounts, this is a multi-day process.
The Decision Layer automates the mechanical steps. Plan/actual data is merged and variances calculated - absolute and percentage. The materiality threshold filters only significant variances. AI identifies causes (price, volume, mix, timing) and creates a commentary draft. Action proposals and strategic interpretation remain with the controller.
The result: the controller spends their time on analysis and recommendations instead of data preparation. The commentary draft accelerates reporting. And management receives the variance report on day 5 instead of day 10.

Decision Record and Right to Challenge
Every decision this agent makes or prepares is documented in a complete decision record. Affected parties (employees, suppliers, auditors) can review, understand, and challenge every individual decision.
Prerequisites
- Planning system with budget data (SAP BPC, Jedox, Anaplan or equivalent)
- ERP system with current actual data
- Configured materiality thresholds per account group and cost centre
- Defined report templates for management reporting
Governance Notes
GoBD-relevant insofar as the variance analysis processes tax-relevant data. The analysis itself is an internal controlling task, but the underlying actual data is subject to retention obligations per AO Paragraph 147.
Action proposals and strategic interpretations have no direct tax relevance but can have significant impact on investment and cost decisions. These remain with the controller and are not automated.
§203 StGB-relevant data is encrypted end-to-end and never passed to AI models in plain text.
Process Documentation Contribution
Infrastructure Contribution
The Budget Variance Analysis Agent builds the variance analysis engine reused by the Management Reporting Agent and Forecast Agent. The commentary framework (automatic narrative draft from metrics) becomes the standard for all reporting agents. The materiality threshold logic forms the foundation for focused reporting.
Builds Decision Logging and Audit Trail used by the Decision Layer for traceability and challengeability of every decision.

Frequently Asked Questions
Can the agent also compare in-year forecasts with the budget?
Yes. Beyond the classic plan/actual comparison, the agent supports forecast/actual and plan/forecast comparisons. The variance analysis works for any combination of plan figures.
How does the agent recognise the cause of a variance?
The agent decomposes variances into price, volume, mix and timing effects. For revenue variances, it analyses whether the price, sales volume or product mix is the cause. For cost variances, it distinguishes between price effects and consumption effects.
Are the commentary drafts automatically sent to management?
No. The draft is presented to the controller for review. The controller adds the strategic interpretation, adjusts wording and approves the final report. AI accelerates creation - content responsibility remains with the human.
