Audit as a by-product of the close
If the monthly reconciliation was done in the workspace, the year-end pack is mostly assembly: the evidence was read and indexed when the item was explained. What remains is the genuinely missing — and those are listed with the name of the person who has to produce them.
The index is the product
Auditors do not want more PDFs; they want to go from their line 4.3 to the balance to the invoices without asking you. The index page does that, and the still-missing list tells them (and your CFO) exactly what is outstanding and why.
Confirmations
Drafted per counterparty from the reconciled balances, tracked as they come back signed, summarised in the schedule the auditor asks for. Last year's two weeks of email becomes an afternoon.
