Hey there, Mohamed.

The option to sell inventory without creating sales transactions (invoice or sales receipts) is unavailable in QuickBooks. 

If you only want to reduce the inventory quantity when consuming the supplies, I suggest creating inventory adjustments. Doing this will help you adjust an item's quantity without recording a sale. This way, you can match what you actually have in stock. 

Here's how:
 

1. Click + New and select Inventory qty adjustment.
2. Enter the Adjustment date.
3. Choose the appropriate account in the Inventory adjustment account drop-down list.
4. For each item, enter either a new quantity or a change in quantity.
5. In the Memo field, enter the details about the adjustment.
6. Select Save and close.

After saving the inventory adjustment, QuickBooks automatically records them to the Inventory Asset and Cost of Goods Sold accounts. For additional reference, you can check this resource: Adjust inventory quantity on hand in QuickBooks Online.

There are also third-party inventory management applications that can help you with this task. You can simply go to the Apps menu and look for the app in the Search bar.

Additionally, you can utilize the following resources when handling inventory in QBO:
 

• Fix negative inventory issues in QuickBooks Online.
• Change product and service item types in QuickBooks.
