What is the available third party inventory mangement module that is compatible with Quickbook online

Thanks for posting in the Community, @accounts338. 

We're unable to provide an available inventory management module third-party app that's compatible with QuickBooks Online (QBO). But I've got the two options you can perform to achieve your goal.

First, you can utilize our built-in inventory management feature in QBO. This way, you can add your products to the Products and Services page. Please take note that this is available in the Plus version. If you don't have this plan, I'd suggest upgrading it. 

To enable the inventory tracking feature in the settings: 

1. Go to the Settings (⚙ ) icon at the upper right. 
2. Select Account and Settings under Your Company. 
3. Choose the Sales tab. 
4. Click Products and services.
5. Check the Show Product/Service column on sales forms box.
6. Turn on both Track quantity and price/rate and Track stock quantity on hand.
7. Click Save.
8. Choose Done.

The screenshot below shows you the last six steps. 

Once done, you can track your products and services when you sell them. Just create an invoice or a sales receipt in QBO. Then, restock your inventory if it's running low or out of stock. Also, you can run reports to view your sales and inventory status. For more details, see Steps 3 to 5 through this article: Setting Up And Tracking Your Inventory. 

The second option is to look for a third-party app from our QBO SG App Center. Just choose the right application that suits your business' inventory needs.

I'm here anytime you have other concerns. Keep safe always, @accounts338.

are there any 3rd party apps that allow you to do inventory builds like in desktop?
