Texas counts to the 15th of a month, not in days from your last day on site. Tell it the month you did the work, and it counts the notice that traps the owner's money, the affidavit, and the day the lien has to be sued on.
Not the day. Texas counts whole months, so a job worked on the 2nd and a job worked on the 30th of the same month share a deadline. One month of work, one notice.
Filing starts one more clock, and it is short.
A copy goes to the owner, and to the original contractor if you are not one, within five days of filing under s.53.055.
Enter the month you did the work
Every obligation below is listed either way, dated or not. A deadline that could not be counted says which input it is waiting for, because the obligation nobody dated is the one that costs somebody their lien.
The monthly notice under s.53.056 is not a formality you send so a lien is valid later. It is the instrument itself. Once the owner has it, the money still owed to the original contractor becomes money the owner is on notice to hold for you, which is why Texas practitioners call it fund trapping. That is leverage arriving months before anybody is arguing.
It runs per month of work, so it is a monthly habit rather than a one-off at the end of a job. A month you never noticed is unsecured for good, and no amount of correct filing afterwards reaches back to it.
Retainage held under your own written contract sits outside all of this. It carries its own notice under s.53.057, counted from your agreement ending rather than from a calendar month, and it is the claim most often lost by a contractor who did everything else right.
Every invoice you raise carries the month it covers, so the notice date for that month is already known. Put the job on the board once and the deadlines sit against it with a countdown, instead of living in a calendar reminder somebody has to remember to set.
The held-back money gets the same treatment: one tracker, one countdown, and a heads-up on the day it becomes claimable. There is no monthly charge for any of it.

When the money was legally due under chapter 28, counted the whole way down: the owner period plus the pass-through to you.
