Do monthly bookkeeping from one admin folder

Idea + starter prompt, not run by us yet

For: Solo owners who lose hours each month renaming receipts and matching payments

A newsletter operator who does not code runs a single prompt with Claude Code aimed at their admin folder. The agent renames documents, assigns expense categories, pairs invoices with payments and writes a monthly summary. In a separate example it worked through 200 PDF invoices, filed them into month folders and produced a spreadsheet.

Steps

1. Copy one month of receipts, invoices and bank exports into a fresh test folder.
2. Open Claude Code in that folder and paste the starter prompt.
3. Check the rename plan and category list before it moves any file.
4. Compare the summary totals with your bank statement for that month.
5. Once it matches, reuse the same prompt next month.

Starter prompt

This folder holds my receipts, invoices and bank export for [month]. Work on this copy only.

1. Propose a new file name for each document in the form [date_vendor_amount] and show me the list.
2. Sort each expense into one of these categories: [your categories].
3. Match invoices to payments in the bank export and list anything that does not match.
4. Build a one-page summary with totals per category.

Wait for my OK after step 1 before renaming or moving anything.
