Our company fabricates exterior metal wall panels for Commercial/Residential/Federal/State buildings. Almost all of our costs are incurred prior to shipping the panels to our customers. We provide shop drawings and engineering services, order the materials for the panels, and fabrication labor all prior to delivery. Since the majority of the documents for lien rights are based off of shipping/delivery dates, we generally send the preliminary paperwork upon shipping. In this case, we have provided the service for the shop drawings and engineering (customer has paid for these services), and have ordered and received the materials for fabrication (customer has failed to pay for materials - received and invoiced in November 2022). No preliminary notice was sent, as no panels were delivered to the job site yet. The job site is in Scottsdale AZ, (Housing/Apartment Complex) Can we still lien? What options do we have prior to looking into a lawsuit?
