Why there is no auto adjustment in my inventory after creating a bill to my purchases?

I'm here to make sure your inventory quantity in QuickBooks Online (QBO) is updated, @irene051310-gmai.

When you create a bill to track what you receive from a supplier, you're letting QuickBooks know that you restocked. This should increase the quantity on hand by the number of items you received.

A cache-related issue in the browser can prevent auto-adjustment of your inventory quantities after creating a bill for your purchases. To isolate this matter, you can perform some troubleshooting steps.

You can start by pulling up your QuickBooks Online (QBO) account using a private browser (incognito). Here's how:

• Press Ctrl + Shift + N (Google Chrome)
• Ctrl + Shift + P (Firefox)
• Control + Option + P (Safari)

Once signed in, go to the Products and Services page from the Gear icon to check your inventory quantity. If the quantity of the items is updated, return to your default browser and clear its cache. This will refresh the system and remove older data that causes viewing and performances issue. However, if this matter continues, I'd recommend using other supported browsers.

Sometimes you might discover that you have either more or fewer of an item than QuickBooks shows. With this, you can manually adjust an item's quantity without recording a purchase or sale, to match what you have in stock. If you wish to know more about this process, you can refer to this article: Adjust inventory quantity on hand in QuickBooks Online.

Also, you can use reports to get helpful insights on the things you buy and sell, and the status of your inventory. To know which reports to pull up, I'd recommend checking out this article: Use reports to see your sales and inventory status.
