Yes, all you need to do is give your workshop or third-party service and maintenance provider a login to your Depot with a Service User Role.
With a Service User Role they can only see the Service tab view of your vehicles. They will be able to monitor your vehicles’ Service schedules and outstanding tasks and upload completed Service records on your behalf. You can limit their access to specific fleets only.
