We would like to track quantities of fuel purchased, used by us, and sold to customers. How can I track that from multiple vendors in QBO?

I would set up the fuel as an inventory item (presumably by the gallon) if you haven't already.  Record the purchase of fuel on bills (New > Bill) or expenses (New > Expense).  When you sell the fuel to customers, use an invoice or sales receipt.  When you use the fuel yourself, sell it to yourself on a $0 invoice or sales receipt.  That keeps all the fuel in inventory until sold to the customer or used by your business and expenses the cost of the fuel to COGS at the time of sale/use. 

Hi there, jpeters02. Thank you for raising your concern. You can follow the steps as Rainflurry advised. I'm here to detail the instructions in accomplishing this in QuickBooks Online (QBO).

To track the quantities of fuel purchased, you can begin by turning on inventory tracking in your QBO and setting up the fuel item as an inventory item. You can refer to this article for the detailed steps: Set up and track your inventory in QuickBooks Online. 

Then, you can create a bill, check, or expense to record the fuel purchase. Creating this purchase will increase the quantity of the fuel item you've set up. Before recording the purchase, let's ensure first that the Items section is displayed on your expense forms. Here's how:
 

1. Click the Gear icon on the upper right corner of the screen.
2. Select the Expenses tab.
3. In the Bills and expenses section, toggle on Show items table on expense and purchase forms.
4. Choose Save, then hit Done.

Afterwards, you can create an invoice or sales receipt to record sale and use of your fuel item.

Moreover, you can also consider collaborating with your accountant as you go through the steps to ensure the books are accurate. If you have no accountant yet, we offer here in QuickBooks a ProAdvisor service. Several of the ProAdvisors also offer a free consultation.

After following the steps, you can now run reports in QBO to monitor your transactions.

If you have more questions about tracking inventory, don't hesitate to leave a message and you'll be catered as soon as possible.
