Every business especially ones, where stock movements are affected, would need to keep a track of all such movements very studiously. Stocks are equity and when they move in and out of the business premises the difference in value between the two would provide either the profit or the loss. That is the core of any business. Generally, it is the profit that should flow in but due to some unforeseen reasons, even losses on some items could be the result.

Every item in stock has to be tabulated with the in and out movement carefully recorded. Prior to the 1970s and the advent of computers and online systems, these stocks were monitored manually. Stock cards were used for every single item and the in and out movement was recorded on it. It was quite a tedious exercise. Though stock cards were updated daily it was necessary to physically count and check stock balances.

This system of periodic stock inventory where stock balances were checked annually especially by grinding the business to a complete halt, was a severe strain on staff and the business itself.

Doing so for every item if it is a large fast moving consumer goods company could push you to the extreme limit.
