Please tell me how to register inventory and record purchases at the same time in QuickBooks Online.

Hello, ise! Thank you for joining us in the QuickBooks Community.

Managing your inventory and recording purchases is essential for maintaining accurate financial records. I want to ensure you have the best guidance to accomplish this in QuickBooks Online (QBO). 

In QBO Plus or Advanced, you only need to set up inventory items on the Products and services page. Then, we can create a bill, expense, or check transaction to record these items you received from a vendor or supplier.

In case inventory tracking is toggled off, and you are yet to set up the inventory items, you can follow these steps:

1. Go to the Gear icon. Then, select Account and settings.
2. Select the Sales tab.
3. Select the Products and services section.
4. Toggle on the Show Product/Service column on sales forms.
5. Turn on both Track quantity and price/rate and Track inventory quantity on hand.
6. Select Save.
7. Click on the Expenses tab. Then, toggle on the Show Items table on expense and purchase forms.

Once done, add your inventory items on the Products and services page. Refer to this article for the detailed steps: Add product and service items to QuickBooks Online. 

The next step is to record your purchase. Depending on whether these items are paid on the spot or plan to pay later, you can either create an expense, check, or bill. Creating either of these transactions will increase the quantity of the inventory item you've set up. Refer to this link to learn the differences between these transactions: Learn the difference between bills, checks, and expenses in QuickBooks Online. Then, you can follow these steps to record the purchase: 

1. Click on the + New button.
2. Choose either Expense, Check, or Bill.
3. Select your Vendor.
4. Choose the Item details section.
   1. In case this section isn't visible, go
5. Enter the item under the Product/Service column, Qty, and the Rate.
6. Ensure the total amount is accurate. Then, hit Save and close.

However, if you're currently subscribed to QuickBooks Online Simple Start or Essentials, you can consider upgrading to a Plus or Advanced subscription to access enhanced inventory management features. Alternatively, you can manually track inventory if upgrading isn't an option at this time.
