All tools (7)

Tool	What it does
`ledger_build`	Derive the double-entry ledger for one period in ONE currency from the invoice, credit note, deposit, expense, bank and asset stores, and register it.
`ledger_export_csv`	Return the period's ledger lines as RFC 4180 CSV, one row per leg including bank_ref.
`ledger_lines`	List the ledger lines for a period, filtered by account, source server, source_id or date; each carries its debit, credit and bank_ref, with the totals of the rows returned.
`ledger_report`	Report a built period account by account: debits, credits, movement and closing balance, plus purchase commitments held as memos and the period's exceptions.
`month_close`	List what a month leaves unposted or unbalanced, with its trial balance and bank reconciliation, then store the close as a snapshot; a later call names any drift against it.
`period_delete`	Delete one built period from the register and give its free-tier slot back.
`trial_balance`	Total the debits and the credits for a period and prove they are equal to the minor unit.

Do I need the other servers?

Yes, to have data. It builds the ledger from records kept by the invoice, bank statement, expense, deposits and asset servers.

Does it replace my accountant?
