Mastering inventory management is crucial for online retailers to avoid stockouts, overstocking, and wasted resources. According to a study, 42% of online retailers experience stockouts, resulting in lost sales and customer dissatisfaction.

Effective inventory management requires accurate forecasting, which can be achieved by analyzing historical sales data and seasonal trends. By doing so, retailers can anticipate demand and adjust their inventory levels accordingly.

To streamline inventory management, online retailers can implement a just-in-time (JIT) inventory system, which ensures that products are delivered to the warehouse just in time to meet customer demand. This approach reduces holding costs and minimizes the risk of stockouts.

Benefits of Good Inventory Management

Good inventory management is crucial for online retailers. It can help you avoid stockouts and overstocking, which can damage your business' reputation and drive away customers.

Automating your inventory tracking can unlock a world of benefits for your business, including building a more resilient business untouched by supply disruptions.

Implementing eCommerce inventory management software can bring several benefits to your business. It can optimize inventory levels, reducing costs associated with excess stock or missed sales due to stockouts.

Having too much inventory for a long time usually isn't beneficial for a company. Having too little inventory can cause a business to lose profit if it cannot fill orders.

Here are some benefits of good inventory management:

  • Decreased human error
  • Increased efficiency and productivity
  • Reduced labor costs
  • Greater insight into trends and demand
  • Fewer stockouts
  • Improved customer satisfaction

Mastering the flow of items through your business and across the supply chain can unlock critical insights that empower you to refine various facets of your operation. Streamlined supply chain dynamics, demand forecasting, inventory optimization, order fulfillment and logistics, and financial planning and analysis are all key areas to focus on.

Maintaining the right amount of stock helps you manage cash flow effectively, allowing you to put that freed-up cash to work for you in other business areas.

Challenges of Inventory Management

Inventory management can be a daunting task for online retailers, and it's essential to understand the common challenges that come with it. Mispicks, which occur when employees pick the wrong item in a customer's order, can cost warehouses nearly $400,000 a year.

Overstocking is another significant issue, where businesses purchase more inventory than they can sell, leading to excess inventory that costs money to store. The retail industry loses over $400 billion a year due to overstocking inventory.

Understocking, on the other hand, occurs when a company doesn't buy enough inventory to meet customers' demands, causing items to run out of stock. Stockouts cost businesses an estimated $1 trillion a year in missed sales opportunities.

Other challenges include inventory tracking errors, where a miscount or data entry typo can make the difference between having enough stock and not fulfilling orders. Using manual inventory management methods not designed for scalability can also lead to these issues.

Here are some common causes of inventory issues:

  • Using methods not designed for scalability, such as manual inventory management
  • Not having visibility across multiple channels
  • Lacking access to real-time inventory data
  • Experiencing demand fluctuations
  • Not identifying underlying problems immediately

If left unchecked, these challenges can lead to a scenario where you can't meet demand or have overestimated your inventory needs, resulting in lost revenue. In fact, a report by Celect and Coresight Research found that a mindboggling $300 billion in revenue is lost due to markdowns.

Inventory Management Techniques

Inventory management is a crucial aspect of running a successful online retail business. Effective inventory management can help you avoid stockouts, reduce waste, and improve customer satisfaction.

There are several inventory management techniques that online retailers can use to streamline their operations. One such technique is the ABC inventory system, which categorizes inventory into three groups: A, B, and C. Items in category A are the most important, and those in category C are the least important.

The ABC inventory system can help you manage your high-value inventory more efficiently. By prioritizing the most important items, you can ensure that they are always available when needed.

Another technique is just-in-time (JIT) inventory management, which involves receiving inventory on an as-needed basis. This can help you avoid dead stock and reduce waste.

Here are some key inventory management techniques to consider:

  • ABC inventory system: categorizes inventory into three groups (A, B, C)
  • Just-in-time (JIT) inventory management: receives inventory on an as-needed basis
  • Reorder point: calculates the ideal amount of stock to hold based on average daily usage and lead time
  • Batch tracking: groups and monitors similar goods to track inventory expiration or defective items
  • Perpetual inventory management: counts inventory in real-time as it arrives or is sold
  • Inventory forecasting: uses historical sales data and seasonal trends to predict demand

ABC Analysis

ABC Analysis is a technique used to categorize inventory items based on their value and impact on the business. It helps organizations prioritize their stock management resources.

By dividing items into three categories - A, B, and C - managers can focus on the most valuable products, which contribute the most to overall profit. Category A includes the most valuable products.

Category B products fall between the most and least valuable, while Category C includes small transactions vital for overall profit but only matter a little individually. This categorization helps identify areas where inventory management can be improved.

The ABC inventory system is a great tool for improving inventory management, allowing companies to make sure their most important items are always available when they need them.

Just In Time

Just-in-time inventory management is a technique in which companies receive inventory on an as-needed basis instead of ordering too much and risking dead stock (inventory that was never sold or used by customers before being removed from sale status).

This approach helps reduce waste and saves storage space by only stocking what's needed to meet current demand.

Companies that implement JIT inventory management need to have a good understanding of their sales patterns and customer behavior to ensure they're ordering the right products at the right time.

By doing so, they can avoid overstocking and minimize the risk of dead stock, which can be costly to remove.

JIT inventory management requires close collaboration between different departments, such as sales, production, and logistics, to ensure a smooth supply chain.

Techniques

Inventory management can become complex, especially for larger apps with many moving parts, encompassing several techniques and strategies.

One essential tool for managing inventory and improving operational efficiency is the reorder point system. By using a reorder point system, businesses can always have the right amount of stock on hand to meet customer demand, leading to lower costs, increased profits, and happier customers.

The reorder point formula calculates the minimum amount of stock a business should have before reordering, taking into account average daily usage, average lead time in days, and safety stock. The formula is: Reorder point = (Average daily usage x average lead time in days) + safety stock.

To prevent going out of stock or overstocking, businesses use inventory forecasting, which involves predicting customer demand based on historical sales data, seasonal trends, and marketing efforts. Inventory management software can help with this process by analyzing sales data and providing alerts when inventory falls below the reorder point.

Another key aspect of inventory management is the process of inventory management, which involves several steps, including:

  • Goods are delivered to your facility.
  • Inspect, sort and store goods.
  • Monitor inventory levels.
  • Stock orders are placed.
  • Stock orders are approved.
  • Take goods from stock.
  • Update inventory levels.
  • Low stock levels trigger purchasing/reordering.

Perpetual inventory management is a system that counts inventory as soon as it arrives, providing real-time insights. It can be recorded manually or using handheld devices that scan product barcodes and RFID tags.

To build an effective inventory management solution, businesses need to focus on three key aspects: organizing, forecasting, and auditing. By implementing these core systems, businesses can run a smoother order management and fulfillment workflow.

ABC analysis is an inventory management technique that helps organizations better manage their high-value inventory by dividing items into three categories: A (most important), B (medium importance), and C (least important). This system allows managers to use their stock management resources more efficiently and improve availability.

The economic order quantity (EOQ) formula is a tool for determining the optimal quantity of inventory to purchase, taking into account total production costs, demand rate, and other factors.

Batch Tracking

Batch tracking is a quality control technique that allows users to group and monitor similar goods to track inventory expiration or trace defective items back to their original batch.

This technique is particularly useful for ensuring the quality and integrity of perishable items, such as food or pharmaceuticals, that have a limited shelf life.

By grouping similar goods, businesses can quickly identify which items are at risk of expiring or becoming defective, allowing them to take corrective action before it's too late.

For example, if a batch of canned goods is found to be defective, batch tracking enables businesses to quickly identify and recall all similar products from the same batch, minimizing the risk of further contamination or spoilage.

Inventory Management Tools and Features

Inventory management tools and features are essential for online retailers to streamline their operations and reduce costs.

Implementing an external ecommerce inventory management system can help reduce wasted time, lost inventory, unnecessary labor, and tax and accounting errors.

Inventory Management Best Practices

Implementing an external ecommerce inventory management system is crucial for online retailers. This can help reduce costs related to wasted time, lost inventory, unnecessary labor, and tax and accounting errors.

Using a platform like Shopify, WooCommerce, or BigCommerce can be a good starting point, but these platforms lack advanced inventory tracking features. This can make business growth risky and difficult to manage.

Organizing, forecasting, and auditing are the three key aspects to building an inventory management solution that works for your business. These core systems will help you run a smoother order management and fulfillment workflow.

By recording these aspects, you'll have more reliable inventory and sales reports. This will give you a better understanding of your business and help you make informed decisions.

Here are the three key aspects of inventory management in more detail:

  • Organizing: This involves setting up a system to track and manage your inventory, including product categorization and labeling.
  • Forecasting: This involves using data and analytics to predict future inventory needs and prevent stockouts or overstocking.
  • Auditing: This involves regularly reviewing and updating your inventory data to ensure accuracy and prevent errors.

Inventory Management Types and Methods

Inventory management is a crucial aspect of running an online retail business. There are two main methods for stocking inventory: outsourcing to third-party dropshippers or print on demand suppliers, and stocking and storing your own inventory.

You can choose one or a combination of both methods, depending on your business needs and resources. For instance, outsourcing can be a great option for small businesses or those just starting out, as it allows you to focus on marketing and sales while leaving inventory management to someone else.

Companies need to have control over all of their inventory and know what they need to replenish. A centralized inventory management system keeps you informed about your assets, covering everything from raw materials to finished products ready for shipment.

Here are the different types of inventory you should keep track of:

  • Raw materials
  • Components and sub-assemblies
  • Packaging materials
  • Works-in-progress
  • Finished goods
  • Stock in transit, known as “pipeline” inventory
  • Maintenance items, repair parts and operating supplies

Prevent Stockouts and Overselling

Preventing stockouts and overselling is crucial for a smooth and satisfying customer experience. You can lose customers and revenue if you're not careful.

Stockouts occur when you run out of inventory, and if you don't keep an eye on inventory levels or market trends, in-demand items can run out of stock. This can be extremely frustrating for online shoppers and lead to canceled orders, lost customers, and revenue loss.

To prevent stockouts, you need to have a way to record all your inventory levels and sales. This will give you more reliable inventory and sales reports. Organizing, forecasting, and auditing are key aspects to building an inventory management solution that works for your business.

Having real-time visibility across all your sales channels minimizes the risk of overselling. A seamless shopping experience builds customer trust and loyalty, and your repeat customers fuel growth. eCommerce inventory management software provides real-time tracking of inventory levels and sends alerts when stock levels are low.

Here are some ways to handle stockouts and prevent future ones:

  • Make sure the item clearly shows it's out of stock or unavailable on your website.
  • Communicate honestly with your customers and explain why the item is currently unavailable on the product's page.
  • If you know when the item will be back in stock, share the estimated availability date with your customers.
  • Consider letting customers pre-order items so you can ship their orders as soon as you replenish your inventory.
  • Prevent future stockouts with inventory management software and safety stock.

By following these steps, you can say goodbye to the frustration of selling out-of-stock items and disappointing customers with backorders.

Consignment

Consignment is a type of inventory management where the consigner, often a vendor or wholesaler, gives their goods to a consignee, typically a retailer, without upfront payment.

The consigner retains ownership of the goods until they are sold by the consignee.

In consignment inventory, the consignee doesn't pay for the inventory until it's sold, which can be a huge advantage for retailers with limited cash flow.

This approach also allows consignors to maintain control over their products and can help them reach a wider audience.

The consignee pays the consigner only for the goods that are sold, which means they only pay for what they've actually sold, not for the entire inventory upfront.

Dropshipping

Dropshipping is an order fulfillment method in which the supplier ships products directly to the customer. This means the store doesn't have to worry about storing or shipping products.

To use dropshipping, a store purchases items from a third-party supplier, who then ships them to the customer. This method is often used when stocking inventory, as one of the two main methods for doing so.

There are two main methods for stocking inventory: outsourcing to third-party dropshippers or print on demand suppliers, and stocking and storing your own inventory.

What Are the Types?

Let's talk about the different types of inventory. There are several categories to consider, including raw materials, components and sub-assemblies, packaging materials, works-in-progress, finished goods, stock in transit, and maintenance items, repair parts, and operating supplies.

Raw materials are the foundation of any product, and companies need to have control over these items to ensure they can be replenished as needed.

Components and sub-assemblies are also crucial, as they help build the final product.

Packaging materials are often overlooked, but they're an essential part of the inventory process.

Stock in transit, also known as pipeline inventory, refers to items that are being shipped from one location to another.

Here's a breakdown of the different types of inventory:

  • Raw materials
  • Components and sub-assemblies
  • Packaging materials
  • Works-in-progress
  • Finished goods
  • Stock in transit (pipeline inventory)
  • Maintenance items, repair parts, and operating supplies

Inventory Management for Ecommerce

Inventory management for ecommerce involves overseeing and controlling the order, storage, and use of products sold online. It's essential for businesses to improve efficiency and reduce operational costs. Perfecting ecommerce inventory management allows businesses to track items in their own warehouse, third-party logistic fulfillment centers, contract manufacturers, consigned inventory with another business, and products sold via dropshipping.

To manage inventory effectively, businesses can use inventory management software that helps track items, monitor multichannel selling strategies, and make accurate predictions on inventory demand. This information can be used to get complete inventory control, maintain ideal stock levels, and set precise reorder points to avoid overstocking, understocking, and stockouts.

Here are some common methods for stocking inventory:

  • Outsourcing to third-party dropshippers or print on demand suppliers
  • Stocking and storing your own inventory

Note that when stocking your own inventory, you need to consider the size of the storage space you need, the types of products you're storing, and the amounts you'll need to stock at a given time.

Multi-Location

Managing inventory across multiple locations can be a challenge, but it's a crucial aspect of ecommerce inventory management. You need to track stock across different warehouses or physical locations to ensure accurate representation and efficient stock management.

A multi-location inventory management system can help you achieve this. This feature is essential for businesses with multiple fulfillment centers or those operating in diverse geographical areas, as stated in Example 8.

To manage inventory effectively across multiple locations, you should consider the following:

  • Stock-keeping unit (SKU): A unique alphanumeric code created by a retailer and given to products to track inventory.
  • Inventory visibility: The ability to see where inventory is and how it’s used.
  • Inventory turnover: The number of times inventory items have been sold and replaced in a given period.
  • Minimum order quantity (MOQ): The smallest inventory a retail business will purchase to keep costs low.

Understanding these concepts will help you implement a robust multi-location inventory management system that suits your business needs. By doing so, you'll be able to manage your inventory more efficiently and make informed decisions about your stock levels.

Ecommerce

Ecommerce is a significant aspect of inventory management, and it's essential to understand the specific challenges and opportunities that come with it.

Managing inventory via an ecommerce platform can be a double-edged sword - while it provides an advantage in setting up a business, it often lacks advanced inventory tracking features, making it crucial to implement an external ecommerce inventory management system.

The sooner you implement such a system, the quicker you can reduce costs related to wasted time, lost inventory, unnecessary labor, and tax and accounting errors.

Proper ecommerce inventory management allows businesses to improve their efficiency and reduce operational costs, given the globalized nature of the world today.

It's not just about tracking items in your own warehouse; you also need to consider items provided through a third-party logistic fulfillment center (3PL), items stored with contract manufacturers, or consigned inventory with another business, as well as products sold via dropshipping.

By accurately optimizing your inventory management for ecommerce, you can better understand your logistics and analytics, and make more accurate predictions on inventory demand.

A centralized hub allows you to manage product listings across all your sales channels, making it easier to manage stock updates across one or multiple inventory locations, ensuring consistency and eliminating the risk of overselling.

Here are some common ways ecommerce stores source products:

  • Product manufacturers
  • Wholesalers or distributors
  • Individuals who hand-make products

By having the right products in stock when your customer is ready to buy, you can increase customer satisfaction and build trust in your brand.

Accurate forecasting can help you avoid stockouts, damaging customer relationships, and impacting your bottom line.

Introduction to Inventory Management

Inventory management is a crucial component of supply chain management that helps businesses track stock levels and the movement of goods. It's the fundamental building block to longevity, allowing businesses to minimize costs, improve cash flow, and boost profitability.

43% of small businesses still don't track their inventory, and the average supply chain accuracy for US retail operations is only 63%. This means many retailers aren't taking advantage of the inventory management software available.

To manage inventory effectively, you need to focus on three key aspects: organizing, forecasting, and auditing. These core systems will help you run a smoother order management and fulfillment workflow.

Organizing your inventory correctly is essential, as it will help you avoid mistakes like mis-shipments, shortages, out-of-stocks, spoilage, overstocks, and mis-picks. By getting this right, the rest of your supply chain will fall into place.

Here are the three key aspects to building an inventory management solution:

  • Organizing
  • Forecasting
  • Auditing

Unlike an enterprise resource planning (ERP) system, an inventory management system focuses on one supply chain process. It often comes with the ability to integrate with other software systems, such as POS (point of sale), sales channel management, and shipping.
