Inventory Management

Learn why managing inventory in Excel leads to errors and chaos, and how a CRM/ERP system helps automate the warehouse, control stock and reserves, and integrate with online stores.


Many small and medium-sized businesses manage their inventory using Excel or Google Sheets. At first glance, it seems convenient and inexpensive. However, in practice, this often leads to confusion, errors in stock levels, and delays in warehouse operations. In this article, we will explore the main issues of Excel-based inventory management and how a CRM/ERP system solves them.

Using spreadsheets for inventory management has several drawbacks:

  1. Manual entry errors — it’s easy to input the wrong quantity or price;

  2. No tracking of reserves and batches — it’s difficult to monitor which products are reserved for customers;
  3. Data loss or duplication — multiple employees may work on different versions of the file;
  4. No integration with sales and online stores — data must be transferred manually.

These issues lead to lost sales, dissatisfied customers, and warehouse chaos.


A CRM/ERP system allows centralized inventory management and automates routine processes:

  • * Stock and reserve control — the system instantly shows available products and reserved units;

  • * Batch and serial number tracking — for precise control of expiration dates and product traceability;

  • * Integration with online stores — automatic stock updates from online sales;

  • * Automatic product deduction upon order — minimizes errors and reduces manual work;


  • * Analytics and reporting — quickly view product turnover, shortages, and surpluses.

  1. The customer places an order through the website or a manager;

  2. The system automatically checks product availability in the warehouse;

  3. The product is reserved for the order, and the stock is updated in real time;

  4. After shipment, the CRM/ERP system deducts the product and updates reports for accounting and management;

  5. The manager sees up-to-date stock levels and can quickly make purchasing decisions.

Managing inventory in Excel may work in the early stages, but as the business grows, it leads to errors and chaos. A CRM/ERP system automates warehouse management, tracks stock and reserves, and integrates with online sales, allowing you to focus on business growth rather than routine tasks.
