Hello ravitrader95-gma,
You can use a 3rd party application to integrate order management in QuickBooks Online. You can visit the Intuit App Center apps.intuit.com to check supported application you can sync in QBO.
Furthermore, QuickBooks Online can help you track inventory items depending in your subscription plan. QBO tracks the items on hand, when it's time to restock and see insights of what you buy and sell.
To add inventory items:
- Click on Settings.
- Click on Products & Services.
- Click on New and select Inventory type.
- Enter the name of the item/product and select a Category.
- Fill out other fields needed.
- Click on Save.
Once done, you can then track your sales in QBO using an invoice or sales receipt transaction. Or if you are using a 3rd party application, the transaction/sales will be sent to QBO from the 3rd party application.
