We prelim every job over a certain dollar amount. In most cases we use an outside company for materials who also send prelim notices just in case we don't pay them. My confusion is,... they want the Job Site, Owner and General Contractor Info. I do not obtain Owner info until after I invoice the job. So there are times when we use their product early in the job , for example first part of December; the job is not invoiced until the 31st when the job is complete they need that owner info before then. Is it my job to provide that to them or is it there job to locate it. We have the Job Site info and the general contractor info is who hired us but the actual property owner many times the General contractor does not even know that info. Do I need to provide this information?
