A customer requested service, and purchased a camera from us. We helped with the installation of a large pole, and mounted the camera to the top of it. The work was completed in May of 2019, but was just closed and billed in October of 2019 due to trying to contact the customer for further work he wanted done, and the number eventually being disconnected. They now have a $4,000 invoice that is going to be going to collections. We only file preliminary liens on jobs that come from our salesmen over $10,000. Where this was a service call, no preliminary lien would've been filed, are we able to take any action on this property?
