What's inside this skill
- Rolling forecast narratives vs prior, forecast, and budget
- Variance broken into volume, price, mix, and timing

- P&L commentary that tells the story behind each number
FP&A analysts and finance teams who want time back for judgment.
An FP&A consultant runs $200+/hr - the complete skill is yours forever.
What you're actually buying
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.
What you get
- → 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
- → Finance business partner communications - financial performance data translated into operational recommendations for business unit leaders

Questions about this product

Which AI tools does this skill work with?+

What is included in this download?+
One .md skill file delivered instantly after purchase. Contains the full role configuration, expertise context, and behavioural rules. No subscription required — yours permanently. Works with Claude, ChatGPT, or any AI chat.
How is this different from using Claude without the Petra skill?+
Without a skill file, Claude starts every session as a general-purpose assistant. With Petra loaded, Claude applies FP&A Analyst expertise and methodology from the first message — no re-explaining, consistent quality every time.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
Is this a physical book?+
No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
