Using quickbooks online, how can I stop selling out of stock inventory?

Hello, omarbaassiri-liv.

I'd like to share some details on how you can stop selling out-of-stock inventory items in QuickBooks. 

We can inactivate the out-of-stock inventory items to stop them from being sold or entered on invoices or sales receipts. Currently, we're unable to do this without inactivating them. 

To inactivate an item: 

1. Click the Gear icon, then select Products and services.
2. Find the out-of-stock item, then click the arrow icon beside Edit. 
3. Select Make inactive. 

I'll also mention that inactivating an out-of-stock item (zero quantity) won't affect your inventory accounts.

Only those items with a negative value or has a quantity of more than zero will have an adjusting entry created when inactivating them. 

Those inactivated out-of-stock items won't show up when you create an invoice or any sales transactions. 

If you've replenished your stocks sometime in the future, we can reactivate those items within the Products and services page. Here's how: 

1. On the Products and services page, click the filter icon.
2. Under Status, select Inactive.
3. Hit Apply. 
4. Find those inactivated out-of-stock items (marked with the (deleted) tag beside their names), then click Make active.

Replenish your stocks according to how you received those items (through a supplier bill or through check or expense). 

If you don't want to inactivate the out-of-stock inventory items, we can set up a reorder point on your items. This way, we'll be aware on what items we want to avoid selling, or what we need to restock on. 

This article will guide you through the process: Get alerts for low or out of stock products. 

If you don't want to inactivate an item or setup the reorder point for alerts, we can send feedback to the developers. We can leave a suggestion that we want to remove out-of-stock items from being sold without inactivating them. 

To send our feedback, simply click the Gear icon, then select Feedback. 
 

I'll add this article in case you want to see your best sellers and inventory stock status in the future: Use reports to see your sales and inventory status.
