Book an entry: two or more lines, each a debit or a credit on an account, which must balance. For anything the other tools don't cover: opening balances, a loan, depreciation, owner's drawings, moving money between accounts, a correction. Entries are never edited; undo one with books_reverse_entry. Lines can carry a tax so the tax report counts them. Price: $0.01 a call. A call that fails costs nothing. ## Use it when Opening balances, a loan, depreciation, owner's drawings, a transfer between accounts, a correction. - For a cost the business paid, use [books_record_expense](https://conecto.chat/tools/books/books_record_expense.md). - For an invoice to a customer, use [invoices_create](https://conecto.chat/tools/invoices/invoices_create.md). ## Say this to your agent > Book the 15,000 euro bank loan that landed in our account on October 1. ## Inputs | Name | Type | Required | Description | Allowed values | Default | |---|---|---|---|---|---| | `date` | string | yes | YYYY-MM-DD (matches ^\\d{4}-\\d{2}-\\d{2}$) | | | | `memo` | string | no | Up to 500 characters. | | | | `reference` | string | no | Up to 120 characters. | | | | `party` | string | no | Who paid or was paid.
