There is no feature for labels in QuickBooks Online at this moment in time, we are always looking for new ways in which we can help our customer and better support their business' we do this through feedback which can be provided on this link. Any feedback given is reviewed by our product development team who will look at the potential of including this into QuickBooks Online in a future release.
Please let us know if there is anything else which we can help with.
