Inventory is woven into its neighbours by links, and they all run both ways. A movement opens its source document; a goods receipt shows the movements it wrote; a product's page carries its whole movement history (§6.4). Follow any thread and you arrive at the paper that caused the number.
The documents themselves print: the adjustment and the transfer as the record of what was authorised, and the stock count as a count sheet — the lines to be counted, with the system quantities present or withheld according to the blind setting, made for clipboards rather than screens. Prints are filed back onto the record they came from, as documents are everywhere (1.9, 1.10) — the signed count sheet belongs on the count, where an auditor will look for it. The enquiries and reports export like every list (1.3), filters respected, so what you send to a spreadsheet is what you were looking at.
