ToolWhat it does
billing_docs_reportOver a date range: what was credited back per currency and against how many invoices, what is still on order per currency, and every open order past its delivery date with days late.

credit_note_deleteRemove one credit note never posted to its invoice and never rendered, freeing that month's slot; the invoice becomes creditable again.
