Record the reporting date, warehouse timezone, final receiving time, locations covered, and system reports used. Export sequential receipt numbers and inventory movements before the data changes. Include receipts entered shortly before and after cutoff, open purchase orders, unmatched vendor invoices, transfer records, returns, and shipments expected around period-end.
Keep both the physical event time and system-entry time. A pallet may arrive before close but be entered the following morning; conversely, a receipt may be pre-entered while the shipment is still in transit. Those cases should appear as exceptions rather than being forced into agreement.
