How to track stock in a small shop in Ghana
You cannot fix a leak you cannot see. This method works with a notebook or a system, but it is much easier when sales reduce stock for you.
Start with a full count
Count every product once, on a quiet day, and write down the quantity and cost price. That is your opening stock.
Record every movement
Every sale, delivery, return and transfer changes stock. If it is not recorded, the number is wrong the next morning.
Set a reorder level
For each fast mover, decide the quantity at which you must reorder, based on how long your supplier takes to deliver.
Count a few items every week
Do a small stock take of your fastest and most expensive items weekly. A full count once a month is enough for the rest.
Investigate differences
When the shelf and the record disagree, write down the reason. Over a few weeks the pattern shows you whether it is damage, theft or a till mistake.
