Finance Reporting Pack — Claude vs the BI stack

I want to start building my financial reporting with the Finance Reporting Pack on my own numbers. Walk me through it.

This is NOT a Terminal or coding install. There is no `git clone`, no `npm install`, no command line. It is all inside the Claude app (claude.ai in a browser, the Claude desktop app, or the Claude add-in inside Excel). Treat me like a finance director or CFO who has never touched code.

What I am setting up: a private Claude Project so the prompts in the vault on this page can read my trial balance / GL export and produce board-grade reporting (3-statement model, variance commentary, board P&L pack, KPI scorecard, cash forecast). Nothing installs on my machine. Once set up, I paste a prompt, replace the `{{TOKENS}}` with my real input, and run it. A finance owner reviews before any report goes to the board.

Walk me through this one step at a time. Wait for me to confirm each step before moving on:

1. Open a browser and go to `claude.ai`, or open the Claude desktop app. For real financial data I want a Team or Enterprise plan so my numbers stay in my own tenant and are not used for training. Tell me how to confirm that setting. If I prefer to work in Excel, tell me how to enable the Claude add-in from the Excel ribbon instead.

2. In the left sidebar, click "Projects", then "Create Project". Name it "Finance Reporting" or the entity name.

3. In Project Knowledge, add the data the prompts will work from (the source I pick in prompt 01): my trial balance, GL export, or prior board packs as CSV or PDF. If I am using the Excel add-in instead, tell me to keep the workbook open and skip the upload.

4. In the Project's Custom Instructions box, paste this: "You are a finance reporting team supervised by a finance owner. Every figure must tie to a source document or my input. Never invent a number. Flag every report for human review before it is issued."

5. Open a new chat inside the Project. Copy prompt 01 (the reporting router) from the vault on this page. Paste it. Answer its questions (entity + basis, which report first, where my data lives, context). This configures every later prompt.

6. Run prompt 02 (3-statement model) or 05 (board P&L pack) and rebuild ONE report I already trust, so I can reconcile the output line-for-line against the version I know is right. Replace each `{{TOKEN}}` with my real input.

7. Read the output. Confirm it followed the `<output_format>`, tied every figure to a source, did not invent anything, and flagged everything per the `<review_gate>`.

8. Before any pack goes to the board, run bonus prompt B4 (source-tie auditor). A single untied figure blocks the pack.

Rules for walking me through this:

- One step at a time. Tell me exactly what to click and where it is on the Claude page or the Excel ribbon.
- Define jargon once: Project, Project Knowledge, Custom Instructions, add-in, ribbon, `<review_gate>`, `{{TOKEN}}`.
- If the UI looks different (web vs desktop vs Excel add-in, Team vs Enterprise), give me the variant. Do NOT tell me a step is "not possible" — tell me to look for a "Projects" or "Workspaces" section, a "Custom Instructions" field, an "Add files" upload, or the Claude add-in under the Excel "Home" or "Insert" ribbon. If none exist, fall back to pasting the trial balance straight into a chat.
- Never tell me to install anything via Terminal. The whole bundle runs from a browser tab, the desktop app, or Excel.
- Anti-pattern call-outs: if I say "my IT blocked claude.ai", tell me about the Team/Enterprise plan with SSO or the desktop app. If I say "I do not have a paid plan", tell me the free plan tests the first prompt but real financial work needs the firm tenant. If I say "the Claude add-in is not in my Excel", tell me to check the Microsoft 365 admin add-in catalog or use the web app with a CSV upload instead.

First message: ask me only "Are you working in claude.ai in a browser, the desktop app, or the Claude add-in inside Excel, and do you have a Team or Enterprise plan so your financials stay in your tenant?" Then start with step 1.

When prompts 01 and 02 (or 05) run cleanly and reconcile to a report I trust, switch into "DM mode" and ask me which report eats the most of my team's month so I can help wire that one live.
