What are Common Challenges in Managing Inventory Without a System?
Efficient and effective inventory management is crucial for any business’s success, especially if you work in retail or manufacturing. However, managing inventory without a system can lead to several significant challenges.
Inaccurate Inventory Levels
Without a systematic approach, keeping accurate track of inventory levels is difficult. Relying on spreadsheets for inventory management can result in inaccuracies and discrepancies. Mistakes in data entry or counting during manual processes can distort the true representation of stock levels. As a result, you can face challenges in maintaining the right stock balance. Overestimation can lead to excess stock, while underestimation can result in stock shortages, impacting sales and customer satisfaction.
Without a real-time IMS, decision-making is based on outdated or incomplete data. This delay can lead to missed opportunities and ineffective responses to market changes, ultimately impacting the business’s ability to compete effectively.
Stockouts and Overstocking
Without accurate demand forecasting, there’s a risk of underestimating demand and experiencing stockouts. Frequent stockouts can lead to lost sales and damage customer trust, while overstocking ties up capital in unsold stock and increases storage costs. Predicting the right amount of product to hold is a complex task that is almost impossible without the insights provided by a management system.
Increased Holding Costs
Holding excessive inventory leads to additional costs, including storage, insurance, and obsolescence risks. Inefficient use of storage space can further contribute to increased holding costs. These costs can significantly impact the financial health of a business, reducing overall profitability.

Inventory Management System Architecture
The design of an IMS is vital for maintaining an organized, efficient, and scalable operation, especially in the context of online retail. The diagram below illustrates the fundamental components of IMS architecture and how they interact throughout the customer purchasing process.
In the center of the diagram, you can see the sequential actions of an online shopper, from logging in to potentially completing a purchase. These actions are the touchpoints where the system interfaces with the user.
A customer database is a repository for user-related information. It houses Personally Identifiable Information (PII), order history, and browsing history, ensuring that customer details are readily available for personalization and order tracking.
The core of the IMS is the inventory management database. It contains detailed product metadata such as Stock Keeping Unit (SKU) descriptions, availability, and the location of the stock within warehouses or stores. It acts as the “source of truth” for inventory management, maintaining the integrity and accuracy of stock levels.
The image database stores visuals, including product images that appear on Product Description Pages (PDPs), search results, and other customer-facing platforms. These images are essential for the online shopping experience, providing customers with the visual details they need to make purchase decisions.
A Product Specs Database/API component provides detailed specifications for products on PDPs. Often sourced from third-party providers, it contains information that the retailer may not manage but is integral to informing customers about product features.
As the user progresses through their shopping journey, the system performs various actions:
- Login triggers a query to the customer database to authenticate and personalize the user experience.
- Viewing PDPs demands simultaneous queries across the inventory, customer, image, and product specs databases to assemble all the relevant data for the product being viewed.
- Adding to the cart often involves temporarily marking the item as sold in the inventory management database to reserve the stock for the customer, which then requires real-time updating based on whether the purchase is completed or the reservation timer expires.
- Checkout engages the customer database again to retrieve necessary user information for the transaction.
- Purchase completion finalizes the inventory management database update, either deducting the stock if the sale is successful or reinstating it if it fails.
Efficient management of these databases is a complex task. This complexity highlights the importance of selecting the right inventory management database tools and technologies to ensure reliability and scalability in inventory management.
