What are the main tools / check list to determine the accuracy level of inventory control management in an organization?

Codes, including barcodes, can make the whole process much easier but it can still be quite time-consuming.

Radio Frequency Identification (RFID) tagging using handheld readers can offer a simple and efficient way to maintain a continuous check on inventory. 

The simplest manual system is the stock book, which suits small businesses with few stock items. It enables you to keep a log of stock received and stock issued.

Stock cards are used for more complex systems. Each type of stock has an associated card, with information such as:

• description
• value
• location
• re-order levels, quantities and lead times (if this method is used)
• supplier details
• information about past stock history

USING ERP SYSTEM LIKE SAP,ORACLE, WMS are the best options .
