The payment clocks
Private work: owner pays within 35 days of the invoice; each party down the chain pays within 7 days of receiving payment; late amounts earn 1.5% per month. Chapter 28 also gives you a right to suspend work after notice (§28.009) — the leverage clause most subs never use. Public work runs under a separate statute (Government Code chapter 2251) with its own clocks. What to check in the draft: payment terms that stretch past these defaults, and invoice preconditions built to restart the clock.
