When using Procore Pay as a payor, both Payments Admins and Payments Disbursers can manage lien waivers in the Company level Payments tool. In Procore Pay, lien waivers are powered by Levelset, a Procore Company.
When using Procore's Invoice Management tools with Procore Pay, only a user with 'Admin' level permissions on the Commitments tool can enable lien waivers and set the default lien waiver templates on a project. Invoicing Settings for commitment contracts are in the project's Invoicing tool.1
1 Access permissions for the Invoicing tool are governed by the permissions set for the user on the Commitments tool. Procore recommends managing user access to the Project Tools in your company's environment with a permissions template. See Manage Project Permissions Templates.
