Some of the contracts outline that we do not invoice until the entire project is complete. Most of our work is finished very early in the project with the exception of final testing near the end. I thought that in IA the lien deadline is calculated based off the final full day of work (8 hours). Because the project often is not finished for months my concern is that if the day we go back for testing doesn't count as the final day of work we are invoicing after the lien deadline has past. Is a full 8 hours required to be counted as the final day or would a partial day of work like a few hours of final testing count?
