I want to alter inventery stock when i create product

Hello there, @peritumhealthcar.

You can alter your inventory stock through the Products and Services menu in QuickBooks Online (QBO). On the said page, you have the option to update the product or service information (i.e. category, quantity on hand, sales price, cost, and accounts).

You'll have to manually adjust your inventory quantity to match what you have in stock and change your stock details. Let me guide you how.

1. Go to the Gear icon.
2. Choose Products and services.
3. Find the inventory stock, select the drop-down arrow under the Action column, then select Adjust quantity.
4. On the Inventory Quantity Adjustment window, change the adjustment date (if necessary) and all other necessary information (i.e. account, new quantity, or change in quantity).
5. Select Save and close.

I've attached screenshots below that show the last three steps.

Once done, I'd recommend pulling up an inventory report (i.e. Inventory Valuation Summary). This way, you're able to acquire details like your transactions for each item, cost, value, and the quantity on hand. Just go to the Sales and customers section in the Report menu's Standard tab.

Additionally, you're able to change the item type for a product or service in QBO. To learn more about this, kindly refer to this article: Product and service item types in QuickBooks Online. It also contains reminders to help you track your products and services accordingly.

Please don't hesitate to drop a comment below if you have other concerns or follow-up inquiries about tracking inventory in QBO. I'm just around to help. Take care always.
