Clarify the submission deadline and the scope, do not hand over the document set without running it through a legal filter, and put oral explanations on a written footing. The first contact sets the tone of the audit.
If the deadline is tight, a reasoned extension request is often available and buys room to prepare properly — ask before the clock runs out, not after. Route everything through a single point of contact, log the legal basis cited for each request, and keep a copy of every document that leaves the building.
Two concrete rights are worth using. When books and records are requested in writing you are as a rule allowed at least fifteen days to produce them, and that period cannot be shortened by pressure at the door. And on the minute recording the start of the audit — and on every interim minute after it — you may enter a reservation against any finding you do not accept. That matters more than it sounds: what the minutes say is what every later stage is built on.
