Transparent working
Enable JavaScript for the interactive output. The method and limits remain readable below.
Method
Count each physical unit once, place one location count on each line, and review the displayed breakdown. Separate open or ambiguous stock from the sealed inventory count.
Example or interpretation
Three location counts of 50, 20 and 10 add to 80. The result is only as reliable as the physical count and item consistency behind the entries.
Limits
This does not inspect packages, confirm sterility or decide that mixed items are interchangeable.
