The Prompt

I am uploading a bank statement CSV for my [type of business — e.g., freelance graphic design studio / retail bakery / HVAC service company].

Please categorize every transaction as an expense, income, or transfer. For expenses, assign each one to the most appropriate category from this list:
- Advertising
- Car & Truck
- Contract Labor
- Insurance
- Office Expenses
- Rent / Lease
- Repairs & Maintenance
- Supplies
- Travel
- Meals (note: 50% deductible)
- Utilities
- Professional Services
- Subscriptions / Software
- Owner Draw / Transfer (do not count these as expenses)

Flag any transaction you are not confident about with [REVIEW] and a one-sentence note explaining why.

Output a markdown table with these columns: Category | Number of Transactions | Total Amount | Example Vendors

Below the table, list all [REVIEW] items separately.
