Hi there BageLady,
It's important that all your transactions be entered correctly so your books can be accurate. QuickBooks Online is a great tool able to help you keep track of your transactions to see the financials of your company. I can point you in the right direction for assistance.
In order to know how you should be recording these bagels and other products being used by you and your staff, I recommend speaking to your accountant. They'll be able to assist in making the entries necessary for your balances to include this amount of used product so your books can be accurate. You can invite your accountant to your books in the My accountant tab. There's also a Find a pro to help button in this section that can help you find a local accountant that has experience with QuickBooks Online.
If you have any other questions, feel free to reach out here.
