Why Use Excel for Inventory Management?

This adaptability is especially valuable for growing businesses or those with complex processes.

Basic features, such as formulas and charts, are easy to learn and use, allowing your teams to quickly learn and adopt the tool without a steep learning curve. Plus, the many online resources and tutorials available make it even easier to master Excel.

Integration with Other Tools

For example, you can import data from sales systems, sync your inventories with e-commerce platforms, or export your reports to accounting software. This integration capability improves operational efficiency and reduces the risk of errors due to manual data entry.

Build a well-organized spreadsheet by including essential columns like product name, SKU, inventory quantity, price, reorder threshold, supplier, and in/out dates. Use tables for easy sorting and searching, and apply conditional formatting to visualize critical thresholds.

3. Use Formulas, Tables and Power Pivot

Automate calculations with formulas like SOMME , MOYENNE , and RECHERCHEV .

To manage larger data sets and create interactive reports, leverage Excel tables, Power Pivot , and the Data Model .

  • Out-of-Stock Rate: Indicates the frequency of stockouts, i.e. occasions when a product is not available when requested.

  • Inventory Entry, Exit, and Forecasting: Track incoming and outgoing inventory movements, as well as inventory forecasts based on historical data. This includes tracking purchase and sale prices, as well as identifying the SKUs that are moving the most and generating the most profit.

  • Minimum Stock Level: Indicates the threshold at which replenishment is necessary.

  • Total Inventory Value: Calculation of the total monetary value of available inventory.

  • Sales Forecast: Estimates of future sales based on historical data.

5. Establish a Monitoring and Update System

Establish regular update procedures (daily, weekly, monthly) and assign data stewardship. Build in quality checks to verify information accuracy and use Power BI to automate repetitive tasks, reducing human error.
