Common mistakes in Kardex management and how to avoid them

The Kardex is a fundamental tool in inventory management, as it allows for a detailed control of the entries and exits of merchandise. However, its incorrect management can lead to significant errors that affect the accuracy of the inventory and, ultimately, the financial health of a company. We will explore some of the most common errors in Kardex management and how to avoid them below.


1. Not updating the Kardex in real-time

One of the most common errors is not updating the Kardex in real-time after each inventory movement. This practice can generate discrepancies in the inventory, as entries and exits are not reflected in real-time, making it difficult to make decisions based on accurate data.

How to avoid it:

It is essential that each time an entry or exit of merchandise is made, the Kardex is updated immediately. Using an automated inventory management system like Inventarios1A can help ensure that all transactions are recorded in real-time, keeping the Kardex always up-to-date.

2. Inconsistencies in product coding

Another common error is the lack of consistency in product coding. If codes are not kept uniform or if duplicate or similar codes are allowed, this can cause confusion and errors in inventory recording.

How to avoid it:

It is crucial to establish a standardized coding system and ensure that all employees follow it strictly. Additionally, implementing a software management that controls and validates product codes before registration, like Inventarios1A, can prevent duplication and maintain consistency in coding.

3. Incorrect quantity registration

Registering incorrect quantities of products is a critical error that can distort the reality of the inventory. This can happen due to human errors during data entry or the lack of verification of physical quantities against records.

How to avoid it:

It is essential to always verify physical quantities of products before registering them in the Kardex. Using barcode scanners or mobile devices integrated with Inventarios1A can minimize human errors and ensure that registered quantities are accurate.

4. Lack of regular Kardex reconciliation

The lack of regular reconciliation between the Kardex and physical inventory is another error that can lead to significant discrepancies. Without a reconciliation process, it is easy for errors to go unnoticed until they become major problems.

How to avoid it:

It is recommended to perform regular reconciliations, comparing physical inventory with Kardex records. Inventarios1A facilitates this process by providing tools for auditing and inventory reconciliation, helping to identify and correct discrepancies in a timely manner.

5. Not assigning clear responsibilities for Kardex management

Often, the lack of clarity in assigning responsibilities can lead to errors in Kardex management. When multiple employees make records without centralized control, the risk of inconsistencies and errors increases.

How to avoid it:

It is vital to designate a responsible person or team for Kardex management. This team should be well-trained in the use of the system and company policies. Inventarios1A allows assigning specific roles within the system, ensuring that only authorized personnel can make critical changes to the Kardex.


Kardex management is a delicate task that requires precision, consistency, and a reliable system. Avoiding the common errors mentioned above is key to maintaining effective inventory control and avoiding unnecessary losses.

By using tools like Inventarios1A, which automate and simplify the Kardex management process, your company can minimize these errors and ensure that inventory data is accurate and reliable. Remember, a well-managed Kardex not only helps you maintain adequate inventory control but is also essential for making informed strategic decisions and maintaining the financial health of your company.
