A distribution cost audit moves at the speed of your documents. Incomplete rate sheets force guesswork; incomplete shipment references force follow-up loops.
Ask finance for three to six months of carrier and warehouse invoices in native PDF or export form, plus the contracts and rate cards active in that window. Ask logistics for the shipment register that ties booking numbers to customer orders.
Include credit notes and disputed invoices already in play. Auditors waste weeks rediscovering disputes your AP team already opened.
Name one person who can answer reference questions within two business days. Silence on a single unclear detention line can stall an entire lane review.
If you are engaging DistSysNet, send the pack before the kickoff call when you can. We spend that hour mapping lanes instead of hunting missing files.
