5 Best Free and Open Source Inventory Management Software


Inventory mismanagement is rampant across the industry despite the best efforts of operations managers, employees, and companies. Mismanagement results in canceled orders due to inventory shortages, which in turn, lead to revenue losses.

Deciding to use inventory management software is the right step, but how do you justify the ROI when you’re already suffering losses? The solution is free inventory management software.

But why free software?

First, it doesn’t cost you anything. This provides the ROI justification to implement it. Second, it helps you improve the customer experience you have to offer. The free software automatically tracks your inventory and alerts you in case of shortage. With this automation, you can significantly reduce the chances of order cancellation.
