Top 7 Free Inventory Management Systems for 2020

inFlow On-Premise (the free, local software version of inFlow’s more robust cloud solution) packs a punch.

In addition to tracking your inventory levels, this app can help you track completed and pending payments, generate purchase orders, process invoices, and more. It can also track costs for each item, helping you produce a more accurate cost of goods sold (COGS) calculation as part of your accounting.

inFlow On-Premise also provides in-depth reporting on your inventory, and it allows you to set up structured workflows that help you track the sales process from order to payment. inFlow On-Premise is also barcode compatible, so you can use barcode scanners to look up items and add them to your orders. You can even scan items using one of the best free inventory apps on the market.

The downsides: While inFlow Cloud allows you to integrate with ecommerce platforms like WooCommerce, Magento, and Shopify, the On-Premise version offers only Shopify integration. It also doesn’t accommodate kitting, accounting integrations, or product variations. And once you hit 100 products or customers, the system stops allowing you to add more without upgrading to the inFlow Cloud service.

You should also keep in mind that inFlow is a PC inventory software, so you’ll need to install a virtual copy of Windows if you want to use the system on a Mac.

All of that should be fine, though, if you’re trying to manage inventory for a small business or you’re just dipping your toes into inventory management software to see if it’s worth the trouble.

Zoho is another free inventory management option that packs in some quality features.

For starters, Zoho is a cloud-based platform, meaning you can access it from your computer or a mobile app. It also includes kitting capabilities (for bundles of products that can be sold together) and alerts that can be triggered anytime your stock drops below an acceptable level.

Unlike a lot of other options on our list, Zoho also offers shipping management tools, so you can easily schedule and track shipments, print packing slips, and generate shipping labels. Plus, the software includes tons of integrations for ecommerce platforms like Shopify and WooCommerce.

The downsides: Zoho imposes one of the strictest limits on sales and purchase orders (only 20 per month). It also limits you to just 12 shipments per month, and the real-time tracking can be a bit buggy compared to smoother paid services. On top of that, Zoho Inventory doesn’t include any bill of material (BOM) functionality, making it difficult to use if you’re running a manufacturing business.

But if your business is still starting out and you’re completing only a few orders per month, you likely won’t find a better way to manage your inventory for free.

PartKeepr is a free, open-source inventory software. That means other users can add functionality to the program as needed. The result? PartKeepr keeps getting better and adding more features over time—all while remaining completely free.

Currently, PartKeepr allows you to track inventory levels for both your finished goods and your components, and it doesn’t put a cap on the number of products or vendors you’re allowed to track in your system. So manufacturers that need to keep tabs on materials, components, and finished products have the flexibility to do it.

PartKeepr also offers multiple-warehouse management, and it allows you to group items from your production runs together in batches. That saves you time if you find a defect within a specific run of items.

The downsides: PartKeepr is a local software, meaning it lives on your computer instead of the cloud. That makes it difficult to use if you need multiple users in multiple locations to have access to your inventory numbers. PartKeepr also doesn’t offer any ecommerce integrations—though that shouldn’t be a huge deal for most manufacturers.

As the only enterprise resource planning (ERP) inventory software on our list, Odoo goes beyond simple inventory tracking and reorder point reminders.

Odoo includes tons of high-end functionality, including customer relationship management (CRM), point-of-sale, human resource, project management, and business management features. It even includes a customer portal where your clients can log in and view the status of their orders.

You can also manage multiple warehouses, complete material resource planning (MRP), and route products directly from your supplier to your customer for faster order fulfillment. And we love that Odoo lets you sell on multiple sales channels and integrate them all into your system.

That’s a lot of functionality packed into a single free platform—making it perfect for rapidly growing businesses that are anticipating a move to a full-blown ERP system.

The downsides: Oddly enough, Odoo offers virtually no integrations, even with major shipping and ecommerce providers. To get that, you’ll need to buy extra modules for your service—and the rates are steep. To make matters worse, businesses may outgrow the free version very quickly, at which point it may be more cost-efficient to consider a different ERP service.

RightControl is a good choice for ecommerce businesses because it offers excellent warehouse management features—even if it does limit you to just one warehouse.

With RightControl, you can not only use a barcode scanner to track inventory and allocate stock but also generate new barcodes and assign them to individual items. That makes it easy for ecommerce businesses to add new products to their catalogue and keep tabs on each item in their inventory.

RightControl software also allows you to create picking lists, so you can fulfill customer orders faster and more accurately.

The downsides: Unfortunately, RightControl does have some limitations. As we already mentioned, it doesn’t support multiple warehouses. But it also limits you to just 10 inventory lines, meaning you’re limited to just 10 product categories.

If you’re running a distribution business on a budget, ABC Inventory’s free platform may be a good fit for you.

ABC Inventory supports multiple warehouses, barcode scanning, and item tracking by location and serial number. The platform also allows you to create unlimited records for new products, so you have all the tools you need to keep tabs on tons of moving products simultaneously.

ABC Inventory software also supports dropshipping and kitting, which gives you greater flexibility to sell and distribute your products in whatever way makes the most sense—whether that’s through consumer sales or wholesale.

Downsides: Like most of the other options on our list, ABC Inventory is a local software, which already makes it hard to allow access for multiple users. But ABC Inventory takes it a step further by also limiting access to just a single PC—and yes, that means it isn’t available on iOS devices. What’s more, it features an outdated interface that can sometimes make it challenging to find all the features you need to properly manage your inventory.

While not an inventory management software per se, Microsoft Excel nonetheless gives you a ton of flexibility to set up your inventory management system in whatever way works for you.

With Excel, you can set up custom formatting, reporting, and more. Plus, you can opt to track only the metrics that matter to you. You can also implement barcode scanning, since most barcode and QR code scanners can upload to Excel. And it’s all available for free on the Microsoft Office website—though you’ll have to use the online version if you don’t want to pay for the software itself.

Downsides: Excel doesn’t integrate directly with ecommerce or accounting software. That doesn’t mean you can’t sell on Amazon, Shopify, or any other sales channels you want—you just have to import everything by hand. Manual inventory management opens the door to more errors, so take that under advisement and maybe implement some kind of redundancy within your inventory system (like having a trusted business partner double-check your work).

Also, to benefit the most from Microsoft Excel, you have to be fairly proficient with the program. If you don’t have the time, patience, or technical skills to deal with Excel’s steep learning curve, you may want to use an inventory management template to get started.
