With QuickBooks Online, you can manually set the dates when recording your invoices. To get the correct item (narcotic drugs), you need to pick it up from the Product/Service column. If the item isn't added to QuickBooks yet, you can set it up through the Products and Services window. I can show you how.
Go to the Gear icon, then select Product and services.
Tap on New from the Products and Services window.
Select the item type from the Product/Service information.
