Payment terms

Net 30 from invoice date is the default term unless your service agreement specifies otherwise.
Late fee of 1.5% per month accrues on unpaid balances over 30 days.
Service holds may apply to accounts more than 60 days past due, which can affect inspection report delivery to AHJs. Reach out before that happens — we'll work with you.
Lien rights are reserved on construction and installation work per Texas Property Code Chapter 53. Preliminary notices and lien notices, when issued, are sent in compliance with Texas statute.
