Hi, I purchase a large lot of snowmobile parts at auction and reselling them on ebay. I do not know how to expense the parts due to I did not buy them individually

I can help you track these parts, @useraarongaudette

You can add those parts individually in QuickBooks Online (QBO) to track them separately in your Profit and Loss report. You can add there the cost of the items and track the expense account. Then, the sales price or rate and the income account that’ll be affected when you make a sale. 

Here are the steps:

1. Go to Sales, then Products and Services.
2. Tap New or Add a product or service.
3. Select an item type like Inventory.
4. Add all the product details like name, SKU, or category for what you're tracking, then hit Save and close.

See these guides for more information about adding products and services in QBO:

• Add inventory products in QuickBooks Online
• Add product and service items to QuickBooks Online
• Change product and service item types in QuickBooks Online

Let me know if there's anything that I can help you track those parts. Take care and have a great rest of the day
