Hi donna-borgford-b,
It's great to see you reaching out to Community. Welcome! Having the option to enter the quantity on your expenses, is essential in obtaining accuracy in your books. I would be glad to provide some clarification about adding the quantity in QuickBooks Online.
Category details enables you to select an expense account used for purchasing items from your vendors, but the option to enter a rate and quantity on the account is unavailable in this section. However, you can enter your purchases in the Item details section, where you can include the rate and quantity of each item.
Feel free to touch base with us again, if you have other questions. We would be happy to help!
