Introduction

eCommerce inventory management software keeps one honest count of what you own and decides when to buy more. Everything else it does — dashboards, forecasting, channel sync — sits on top of getting those two things right across every place you sell.

Managing inventory is essential for the success of eCommerce businesses. It helps to minimize costs, optimize stock levels, and maximize customer satisfaction. As technology advances and consumer demand increases, software solutions have become increasingly important for eCommerce inventory management.

But how do you decide which inventory management software is right for you? If you already have an inventory tool in place, how do you migrate that data to new software? Let's take a look at some of the best inventory management software for eCommerce, and what you need to watch out for when you are choosing one.

What Is eCommerce Inventory Management Software?

ECommerce inventory management software is a specialized type of inventory management software designed for online retailers or eCommerce businesses. It helps eCommerce businesses to manage their inventory levels, sales, and orders across various online sales channels such as:

The right eCommerce inventory management software typically includes features such as real-time inventory tracking, multi-channel order management, shipping integration, automated stock updates, and reporting. It can also help businesses to optimize their inventory levels, reduce out-of-stock situations, and prevent overselling.

The four numbers that decide everything.

Feature lists are hard to compare. These four are not, and every product below is really competing on how well it calculates them.

Lead time

How long a supplier actually takes, measured rather than quoted. It is the input everything else depends on, and the one most often entered once and never revisited.

Reorder point

The stock level that triggers a purchase order: demand during lead time, plus safety stock. Set it from last quarter's real demand, not from a number someone picked in 2019.

Safety stock

The buffer covering the days a supplier runs late or demand spikes. Too little and you stock out; too much and it becomes dead stock nobody writes off.

Carrying cost

What holding stock costs per year — capital, storage, insurance, shrinkage and obsolescence. Commonly 20–30% of inventory value, and the reason more stock is not a free answer to stockouts.

These interact in a way that makes the software worth paying for, and it is worth walking through once. Lengthen lead time and the reorder point has to rise, which raises average stock held, which raises carrying cost. Cut safety stock to release cash and stockout risk climbs, which costs a lost sale plus, on a marketplace, a ranking penalty that outlasts the stockout itself. Run the same SKU across a website, Amazon and a retail counter and the calculation has to happen against one pooled quantity, or each channel quietly reserves stock the others think they can sell. That is the real job: not reporting what happened, but recalculating those four numbers per SKU, per channel, as demand and supplier performance move. A system that only shows you current quantity is a ledger. A system that tells you what to buy on Tuesday and how much of it is doing the work.

How to test this in a demo

Ask a vendor to change one supplier's lead time and show you which reorder points move as a result. Products that model this properly will demonstrate it immediately.

That single question decides whether any inventory tool works. It is an integration problem before it is a software choice.

The Challenges of eCommerce Inventory Management Software

Ecommerce inventory management software is essential for any online retailer to manage their inventory effectively. However, there are several challenges that come with using this type of software.

Key Considerations When Purchasing eCommerce Inventory Management Software

When considering the purchase of eCommerce inventory management software, there are several key factors that should be taken into account.

Software According to Your Business

The type of software needed depends on a variety of factors such as the size and type of business being operated. Small businesses may require simpler solutions than larger companies with multiple locations and complex operations. Software solutions such as Zoho Inventory can provide comprehensive features from basic stock tracking to order fulfillment, invoicing, warehouse management, and more.

Budget

Budget can also play an important role in choosing eCommerce inventory management software. It is essential to consider how much money is available for purchasing and implementing the solution before making a decision on which product to buy. In addition, determining whether additional training or support is needed should be factored into the overall cost of ownership.

Know-how for Maintenance

It's important to understand what level of technical know-how is necessary in order to make use of an inventory management system effectively. While some solutions are designed with user-friendly interfaces and require minimal technical knowledge to operate, others may require more advanced technical skills in order to get the full benefit out of them.

To help businesses make informed decisions about their inventory management systems, we've brought together 14 of the best inventory management software for eCommerce (in no particular order).

Connecting a chosen system to the rest of your stack is a separate question from picking one. If the requirement is keeping quantities in step between an ERP, a warehouse system and your storefront, see inventory sync, which covers the integration side rather than the software selection.

Sortly

Sortly is a mobile-first inventory and asset tracking app for small teams, built around photos, folders, barcode and QR scanning, and low-stock alerts rather than eCommerce channel sync. Each folder can stand for a warehouse, room or job site, so the same item can be tracked in several locations.

Sortly connects to QuickBooks Online, Amazon Business, AppFolio, Slack and Microsoft Teams, and offers webhooks and an API. It has no native Shopify, WooCommerce or Magento integration, so a store needs the API or middleware to sync stock.

Zoho Inventory

It pulls data from systems such as NetSuite, Sage, Acumatica, Microsoft Dynamics 365 Business Central, SAP Business One and SYSPRO, and returns ranked daily replenishment and transfer recommendations. Orders, shipping and returns stay in the ERP.

Odoo

Odoo is designed to be used by small, medium, and large businesses alike, providing a range of features that simplify the task of managing inventory across multiple warehouses and outlets. Odoo integrates with many third-party applications, allowing users to automate tasks such as order fulfillment and stock replenishment.

Frequently asked questions

What are the challenges associated with eCommerce inventory management software?

ECommerce inventory management software faces several challenges that can impact efficiency and profitability. One major issue is real-time tracking and synchronization across multiple sales channels, which can lead to inaccurate stock levels and overselling if not properly managed. Integration complexities with other systems, such as accounting, shipping, or customer relationship management (CRM) tools, can also create bottlenecks. Also, scalability is a challenge, as businesses with rapidly growing inventories need software that can adapt to increasing demands. Cost and setup difficulties can deter smaller businesses from implementing advanced inventory solutions. Moreover, ensuring data security is critical to prevent breaches, while the accuracy of demand forecasting remains a persistent issue that can lead to either excess inventory or stockouts. Finally, software usability and training for employees are essential, as overly complex systems can hinder efficient operations and lead to human errors.

What is inventory management software?

Inventory management software is a digital tool used to track, manage, and optimize a company's inventory levels and supply chain operations. It allows businesses to monitor stock levels, record sales, and purchase orders, track shipments, and generate reports on inventory performance. The software helps companies streamline their supply chain and reduce the risk of stockouts, overstocking, and losses due to spoilage or expiration. It provides real-time visibility into inventory levels and enables businesses to make data-driven decisions regarding procurement, pricing, and promotions. Inventory management software can be tailored to different industries and business sizes, making it an essential tool for modern businesses looking to optimize their operations.

What are the main benefits of using inventory management software?

Inventory management software can provide businesses with several key benefits, such as increased efficiency, improved accuracy, and reduced costs. By automating processes such as order fulfillment and inventory tracking, businesses can streamline their operations and reduce the need for manual labor. This can lead to fewer errors and faster order processing times. Inventory management software can help businesses optimize their inventory levels, ensuring that they always have the right amount of stock on hand to meet customer demand without carrying excess inventory. This can lead to improved cash flow and reduced storage costs. Finally, by providing valuable data and analytics, inventory management software can help businesses make informed decisions and improve overall performance.

How do you manage inventory in eCommerce?

Managing inventory in eCommerce requires careful planning and attention to detail. One of the key considerations is selecting the right inventory management software, which can automate many of the tasks involved in inventory management, such as tracking inventory levels and generating purchase orders. It is also important to set up a system for receiving and storing inventory, as well as fulfilling orders and managing returns. Regular monitoring of inventory levels and sales trends can help businesses optimize their stock levels and avoid stockouts. Businesses can use various marketing and sales strategies, such as bundling and up-selling, to help move inventory and improve cash flow.

How do we set a reorder point without a forecasting team?

Start with average daily demand over the last 90 days, multiply by supplier lead time in days, and add safety stock covering your worst recent lead-time overrun. That arithmetic is good enough to beat a static minimum, and it is what most software automates rather than invents. Refine it per SKU once you can see which ones actually move.

Why does the same SKU show different stock on different channels?

Because each channel is holding its own count instead of drawing on a pooled quantity. Either the sync interval is long enough for orders to land in between, or each channel has stock allocated to it that the others cannot see. Ask any vendor how often they push quantity to each marketplace and whether allocation is per channel or pooled — the answer decides whether you oversell.
