Where it lives
/stock— per-location stock counts, running value in your workspace currency, and adjustment history.
Stock counts
Each product from the Finance module's catalog gets a per-location quantity. Counting a location updates the quantity and recalculates the location's total stock value from each item's unit cost.
Adjustments
Quantity changes outside a full count — breakage, spoilage, internal use — are logged as adjustments with a reason, so shrinkage is traceable back to a cause and a date instead of just showing up as an unexplained count discrepancy later.
Shared product catalog
Stock reads from the same /products catalog Finance already uses — there is no separate item setup. Adding stock tracking to a business that already uses Finance is just a plan change, not a data migration.
