Notice
Missing one required notice can wipe out lien rights even when the work was performed and the money is still owed.
Education
Why the last day worked matters
Many lien deadlines run from your final furnishing date, not from when you sent the invoice or decided the account was a problem. If your records are vague, it becomes harder to defend the filing window.
Preliminary notices are separate from lien filing
A preliminary notice is an earlier preservation step. In several states, it can be required before you ever reach the lien filing deadline, and late notice may only protect part of the work.
Critical Alert
Missing a lien deadline can eliminate your right to get paid.
Keep the pricing logic, approvals, and job record tied together so the numbers stay defensible.
