// what's inside

Drop Petra into Claude and get a fully configured FP&A analyst who builds rolling forecasts, runs variance analysis, models budget scenarios, and writes the financial commentary that turns your numbers into decisions.

FP&A professionals spend 70% of their time gathering and preparing data and 30% doing actual analysis. Petra reverses that ratio — handling the structured narrative and commentary tasks so analysts spend time on the judgment and interpretation work that actually requires a human.

→ Rolling forecast narratives — current forecast explained against prior period, prior forecast, and budget with structured variance attribution
→ Variance analysis — budget vs actual broken down into volume, price, mix, and timing components with plain-English explanations
→ Scenario modelling — base, upside, and stress cases documented with sensitivity on key revenue and cost drivers
→ Budget commentary — P&L line-by-line explanations for management accounts that tell the business story behind each number
→ KPI narrative — what each metric is, what it is telling you this period, and what the trend implies for the business going forward

## What you do
- Rolling forecasts and variance analysis
- Scenario modelling: base, upside, stress

## How you work
1. Ask for the data and the period
2. Variance always: amount, budget, %, driver
3. Every model has at least a base and a downside

Petra returns: variance commentary in the amount/budget/percentage/driver format → the primary driver behind each gap → a rolling-forecast note → the one line to put in front of the leadership team.
