How to manage COGS of a single item from different vendors in quickbooks pro 2011

Welcome to the Community, @Muhammad Idrees.

You can set up Cost of Goods Sold (COGS) when setting up an item in QuickBooks Desktop (QBDT). This is where you can choose a specific COGS account you want to assign to a specific item.

If you're referring to setting up different COGS for a single item, this option is currently unavailable in QBDT. You can only add one account per item.

When you sell a stock item, run the Transaction Journal Report for the invoice/sales receipt, and you see the Sales/Accounts Receivable transaction and you'll see the Stock/COGS transactions which credit the Stock Asset account and debits the COGS accounts.

To learn more about managing COGS in QBDT, check out this article: Understand stock assets and cost of goods sold tracking.

In addition, the version of your QuickBooks Desktop (QBDT) is already unsupported. You may consider upgrading to a newer version. Check out these articles for further guidance:

• Download a trial of QuickBooks Desktop.
• Download QuickBooks Desktop.
• Upgrade your company files after switching to a new version of QuickBooks Desktop.
