Built lists Lien Waiver Management at $1,000 a month, discounted when you process your payments through Built. If you pay subs from your own accounting system and just need the waivers collected, SubLien costs $199 a month for up to 25 active vendors with unlimited waivers: subs sign from an emailed link with no account, and reminders run until each waiver comes back. The same plan also collects each sub’s certificate of insurance, W-9 and signed agreements, so one vendor record holds everything you need before you pay.
