How can a finance team use AI to explain why actual spending and revenue differ from budget each month, so budget owners get clear answers instead of a spreadsheet of numbers?

# How can a finance team use AI to explain why actual spending and revenue differ from budget each month, so budget owners get clear answers instead of a spreadsheet of numbers?

Start from your budget, the closed actuals for the month, your chart of accounts and the threshold above which a variance needs an explanation. AI compares actuals with budget by account, department and project, lists variances above the threshold, digs into the transactions behind each one to suggest likely causes such as timing, one-off costs, price or volume changes, and drafts a short note for each budget owner with questions where the cause is unclear. Budget owners confirm or correct every explanation, the finance lead reviews the final commentary before it goes to leadership, and the system never changes the budget, forecasts or ledger on its own.

## What this means in practice

- Start from the budget, closed actuals, chart of accounts and a variance threshold.
- Compare actuals with budget and list variances above the threshold.
- Suggest likely causes from the transactions behind each variance.
- Draft notes and questions for budget owners to confirm or correct.
- Have the finance lead review the commentary and never change the books automatically.

## How Lid Vizion approaches it

We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
