Note: This article covers inventory and logistics management services available only in Japan. The information below will not be directly relevant if you are not selling in the Japanese market.

Accurate inventory management is essential to running a smooth e-commerce site. Poor inventory management directly affects your business, leading to lost sales opportunities, reduced customer satisfaction, and cash flow problems.

This article introduces recommended inventory management apps that integrate with Shopify. We'll cover everything from the benefits of inventory management to how to choose the right app.

What Are the Benefits of Inventory Management?

Proper inventory management helps you avoid having too much or too little stock, reducing the risk of stockouts. Building a system that avoids long-term excess inventory and stockouts also helps reduce management costs.

Other concrete benefits include the following.

Stabilized cash flow

Thorough inventory management smooths out your cash flow, stabilizing your business.

Improved product turnover

A higher inventory turnover rate makes it easier to maintain product quality, reducing the risk of deterioration or contamination from long-term storage.

Improved operational efficiency

Accurately tracking stock levels reduces wasted work and improves overall operational efficiency.

Cost reduction

Maintaining a minimal stock level reduces storage space and labor costs.

Risks Caused by Poor Inventory Management

Whether you run an e-commerce site or a physical store, maintaining appropriate inventory levels is essential for healthy store operations. Insufficient inventory management can lead to problems such as the following:

  • Cash flow strain from excess inventory
  • Lost sales opportunities from stockouts
  • Inaccurate business data due to inventory discrepancies

Key Points for Inventory Management on Shopify

Inventory management on an e-commerce site like Shopify differs in some ways from inventory management at a physical store. Keep the following five points in mind for proper inventory management on your e-commerce site.

Accurately tracking stock levels

Always knowing your accurate stock levels prevents the risk of excess inventory or stockouts. Discrepancies make it difficult to maintain appropriate inventory levels.

Purchasing based on data analysis

Analyzing past sales data and market trends, and purchasing only the quantity you need, prevents excess inventory from building up.

Improving turnover through appropriate inventory levels

Maintaining appropriate stock levels increases inventory turnover, preventing rising costs and lost sales opportunities.

Updating pages for sold-out products

When a product sells out, it's important to promptly update its page so customers don't accidentally order a product they can't actually buy. On Shopify, you can prevent customers from ordering out-of-stock items by unchecking "Continue selling when out of stock" in product management.

Consider adopting an external service

If you run multiple e-commerce sites beyond just Shopify, or also sell products at a physical store, we recommend using an external service or app to manage your inventory centrally.

This not only prevents human error, but also reduces the risk of accidentally selling a product that's out of stock. Adopt an automated management system to achieve reliable inventory management.

How to Manage Inventory Using Shopify's Built-In Features

You can easily manage inventory on Shopify from the "Inventory" page or the "product details page" in product management, both in the admin.

Shopify's built-in inventory management feature lets you easily manage and track each product's stock level in your store in real time. You set the stock level for a product, and it automatically decreases as sales occur, preventing manual errors. There's also a feature that sends automatic notifications when stock runs low, so you can restock quickly.

Definitions of Shopify's Inventory Statuses

Inventory Status Definition
On hand All inventory (physical stock) located at a specific location.
Available Inventory that can be sold.
Committed Inventory tied to an order that hasn't shipped yet.
Unavailable Inventory held back for other reasons, such as damage, quality control, or safety stock.

Drawbacks of Using Shopify's Inventory Management

Shopify's built-in inventory management feature is very convenient, but it has some limitations.

Management becomes more complex as your product count grows

As your product count grows, inventory management using the built-in feature alone can become complex, and efficiency may drop.

Not well suited for selling across multiple platforms

If you sell across multiple e-commerce platforms, inventory management errors become more likely. In this case, it's best to use an external service to manage inventory centrally.

How to Choose an Inventory Management App for Shopify

There are many apps available for managing inventory on Shopify. To choose the one that fits your site, check the following points.

Balance between cost and features

Some inventory management apps are free, but many are paid. Choose an app whose features are worth the cost, with neither too much nor too little functionality, matching how your business actually operates.

Whether it can sync inventory across multiple sites

If you run multiple e-commerce sites or physical stores, check whether the app can sync and centrally manage inventory across all your sales channels. Since the features and coverage offered differ by app or service, we recommend comparing options carefully before adopting one, based on your business's operating plan.
