3 Best Free and Open Source Inventory Management Software

Published by in Logistics Technology

If you’re a warehouse or operations manager, you must realize how difficult managing inventory is. While you need to record the units, item number, and location of each inventory item, you also need to ensure that there is enough stock to fulfill customer orders.

Managing all of this manually isn’t easy and is prone to errors. For instance, if your inventory records don’t reflect accurate stock volumes, you risk stock outages. And during audits, inaccurate inventory records can lead to fines and penalties.

An inventory management solution simplifies the inventory tracking process and eliminates human errors in recording inventory data. Moreover, the inventory reports that the system generates also save the effort in manual counting during audits.

However, if you are still concerned whether investing in an inventory management solution is right for you, you could start by using a free inventory management system first. This will allow you to assess the usefulness of the software before you purchase a full-fledged product.

To help you get started, we’ve identified the three best free inventory management software solutions (listed alphabetically). Each of these systems appears on the Capterra Shortlist that ranks software solutions based on ratings, popularity, and functionality, among others. (See full selection methodology here).

See all free inventory management tools

This article looks at three highly rated, free inventory management software options. See the full list of free solutions.

  • Pricing: Of the several modules the vendor offers, the first two are available free of cost. You’ll need to pay for any additional module beyond that.

Odoo is an open source ERP solution that offers modules for managing various business functions, including CRM, eCommerce management, point of sale (POS), expense management, supply chain, and inventory management.

Odoo’s inventory management module allows users to track delivery orders, dropshipping requests, backorders, receptions, and transfer requests for inventory items.

It also supports barcode scanner technology via Wi-Fi, Bluetooth, or USB connections. There is seamless integration with the other modules in the ERP ecosystem, so you don’t need to manually update inventory and accounting reports whenever a product is sold.

Odoo offers customer support via portal requests and phone.

How to choose the right inventory management software for your business

The following approach can help you identify the right free inventory management tool for your business:

  • Shortlist solutions based on the number of monthly orders allowed in the free plan.
  • Review the features listed in Capterra’s inventory management software buyers guide and select the features you’ll need in your business. Shortlist those products that offer all the essential features you need.
  • Decide an annual budget for inventory management software. Select products that fit within your budget, so that you can afford all the upgrades.

Common questions to ask while selecting a free or open source inventory management solution

Selecting free inventory management software is not a straightforward decision. You’ll be faced with a lot of doubts when finalizing the right software to invest in.

We’ve summed up key questions that you should ask the software vendor before implementing free inventory software.

  • Do upgrade plans include phone and email support? Not all technical queries can be addressed through self-help support materials. To address these queries, you’ll need to interact with the technical support staff directly, and phone and email support make this possible.
  • Does the software integrate with the software solution I have in my business? Without integration, you’ll need to export data from your inventory software and upload it to another. This is not only tedious but also limits your ability to keep all systems up-to-date in real time.
  • How frequently do you release software updates? If the software provider releases feature updates frequently, it indicates that the software provider is focused on adding new features and fixing issues in the existing ones.
  • Can you share testimonials from a current customer from my industry? The testimonials from your industry peers will help you assess the utility of the software in your line of business.

Great comparison

WIZT keeps track of every single item you’ve stored. Tracking an item is as simple as snapping a picture; finding it again is as simple as asking “Where is that thing?
