This is for a job in Tennessee. We are a supplier on a commercial job. I sent our notice of non payment but the system is telling me my deadline was 9/16/21. Our invoice does show 6/18/21. Based on this can I still file a lien on this?
While I'm not able to help you navigate Levelset's software platform, I can provide some information that should help you come to some conclusions on your claim.
The deadline for a sub or supplier's mechanics lien on a Tennessee commercial project will change depending on whether or not a Notice of Completion gets filed. If the document does not get filed, the deadline to pursue a lien claim is 90 days after the project is completed. If a Notice of Completion does get filed, the lien deadline will be 30 days from when that Notice of Completion was filed.

Finally, note that it's often hard for a subcontractor or supplier to have accurate data on hand for when a project is actually completed. And, as a result, it's common to use the party's "last furnishing date" to approximate a very conservative deadline for pursuing a lien. Regardless, the above rules re: liens and Notices of Completion still represent the actual deadlines for pursuing TN mechanics liens on commercial projects.
