Hi there ndamo,
It's vital that all your transactions be entered properly in your books so the account balances can be accurate. QuickBooks Online is a great tool ab;e to help you have access to your books from any location with an internet connection. I can provide some information about invoices.
In Quickbooks online, there isn't a way to create a non-posting invoice in QuickBooks Online. That being said, all invoices created will affect the books unless they are deleted or voided.
if you have any other questions, feel free to reach out here.
