Tool	What it does
`deposit_apply`	Apply part of a held deposit to one invoice: it records that amount as a PAYMENT through the invoice server.
`deposit_balance`	Answer "how much of theirs am I holding?" for one client or everyone: received, applied to invoices, refunded and still held, one row per currency, never added across them.
`deposit_delete`	Delete a deposit that never moved money, freeing that month's free-tier slot.
`deposit_list`	List deposits newest first: DEP number, client, kind, date, reference and what was received, applied, refunded and still held, with the same four totalled per currency.
`deposit_record`	Record a security or retainer deposit received from a client, in minor units, with its currency, the date it arrived and the bank reference.
`deposit_refund`	Give part or all of a held deposit back to the client, with the date and how it was sent.
`deposit_statement_pdf`	Call this tool to write one client's A4 deposit statement and return the file path.
`deposit_statement_text`	Turn one client's deposits into a plain-text statement to paste into an email: every movement in date order and the closing balance held.
`deposits_report`	The deposit book at a date: held per currency, received, applied and refunded, the oldest holdings with days held, and every deposit older than N days with nothing applied.

Questions

Does it work with the Invoice server?

Yes. deposit_apply records the amount as a payment through the invoice server.

Can I apply more than the invoice owes?

No. The amount defaults to the lesser of what is held and what's owed, and more is refused.
