Stock control systems - keeping track manually
Using inventory listing, stock codes, stock books and a simple re-order system to manage your stock
Stocktaking involves making an inventory, or list, of stock, and noting its location and value. It's often an annual exercise - a kind of audit to work out the value of the stock as part of the accounting process.
Codes, including barcodes, can make the whole process much easier but it can still be quite time consuming. Checking stock more frequently - a rolling stocktake - avoids a massive annual exercise, but demands constant attention throughout the year. Radio Frequency Identification (RFID) tagging using hand-held readers can offer a simple and efficient way to maintain a continuous check on inventory. See using RFID for inventory control, stock security and quality management.
Any stock control system must enable you to:
- track stock levels
- make orders
- issue stock
The simplest manual system is the stock book, which suits small businesses with few stock items. It helps you to keep a log of stock received and stock issued.
It can be used alongside a simple reorder system. For example, the two-bin system works by having two containers of stock items. When one is empty, it's time to start using the second bin and order more stock to fill up the empty one.
Stock cards are used for more complex systems. Each type of stock has an associated card, with information such as:
- description
- value
- location
- reorder levels, quantities and lead times (if this method is used)
- supplier details
- information about past stock history
More sophisticated manual systems incorporate coding to classify items. Codes might indicate the value of the stock, its location and which batch it is from, which is useful for quality control.
