Get a close checklist that answers from your books, not from a chatbot
A chatbot that has never seen your trial balance will invent confident nonsense. Close work needs your files in the loop and humans on anything that posts.
Who this is for
Controllers, fractional CFOs, and ops-finance partners who already export Sheets or CSV for close. If your ledger AI lives inside QuickBooks, Xero, or NetSuite and that is enough, start from those reviews instead — this page is the Claude Projects pattern.
How to do it
Standing instructions stay in the Project: chart aliases, materiality, “never invent amounts,” “mark Unknown.”
1. Step 1 — Put close files in one Project
What it is: Use Claude for finance / Claude Projects:
- Upload sanitized exports (strip customer PII you do not need).
- Paste standing instructions: chart aliases, materiality threshold, “never invent amounts,” “mark Unknown.”
- Keep the same Project month to month so instructions do not drift in chat history.
Project name: Close — [Company]. Upload last month’s P&L and balance sheet only. Customer names you do not need are already stripped.
Create Project Close — [Company]. Upload last month’s P&L and balance sheet exports only. Instructions: “You only use uploaded files. If a figure is missing, write Unknown. Do not invent journal entries.”
2. Step 2 — Ask for a checklist and variance draft with guardrails
What it is: Ask for:
- A close checklist ordered by dependency (what blocks what).
- Month-over-month variance bullets for the top movers with figures cited from the upload.
- A list of questions for the bookkeeper — not answers you cannot source.
If numbers live in Google Sheets and you want in-grid help, see Gemini in Sheets and Gemini for finance — same rule: no invented figures.
The prompt asks for the five largest month-over-month absolute variances with amounts from the file, then an eight-line checklist. Silent cells stay Unknown.
Using only the uploaded P&L, list the five largest month-over-month absolute variances with amounts from the file. Then draft an 8-line close checklist. Mark Unknown where the file is silent.
3. Step 3 — Human gate before anything posts
What it is: AI drafts checklists and narrative. Humans:
- Confirm amounts against the system of record
- Post journals
- Approve accruals
- Send the board pack
The checklist has two columns: AI draft and human confirmed. A variance line stays open until someone checks it against the ledger.
Add a column on the checklist: AI draft / human confirmed. Nothing moves to “done” without the second mark.
Pricing context (October 2026)
Claude plan prices are on Claude for finance and Claude. QuickBooks, Xero, Gemini, and ChatGPT finance prices stay on their reviews. This page does not invent them. Dated October 2026.
Uncertainty: Which Claude plan includes Projects, file limits, and finance add-ons change. Confirm on the vendor site before close week. A $9 spreadsheet or $19 audit is only relevant if several finance AI seats overlap — not required to run this checklist.
When this helps (honest take)
Useful when you already export close packs and want faster first drafts.
Not useful when you refuse to upload or paste sanitized numbers — then you only get generic advice, which is the failure mode this page exists to avoid.

FAQ
Can the checklist invent a journal entry?
No. If a figure is missing, the draft should say Unknown. Humans post journals.
What files go in the first Project?
Sanitized P&L and balance sheet exports. Strip customer details you do not need.
When should we start in QuickBooks or Xero instead?
When ledger AI inside that system is already enough. This page is the Claude Projects pattern.
Who confirms amounts?
A human, against the system of record, before anything is marked done.
Optional next step
Soft next step only if multiple finance AI seats overlap: $9 spreadsheet · $19 audit. The checklist stands alone.
