Inventory Valuation

The question: what is the stock worth — on a date? Pick a date and the report rebuilds every position as it stood then, replaying the movement ledger: each product in each warehouse with its quantity and its value at the moving average as at that moment — the same basis the books move on, so a valuation at today agrees with the live balances to the cent. Grouped by warehouse, with subtotals and a grand total; filter by warehouse or category; export it for the file. Use it at period ends, for insurance schedules, and whenever someone asks what the stock was worth then rather than now — the answer is reconstructed from the ledger, never from a figure someone saved.
