Builders, subcontractors and suppliers often need different updates as a project moves from proposal to payment. Handoff gives construction operators events such as a new contact, proposal sent, proposal approved, invoice paid and new project, so the right SMS can follow the work without someone checking every record.

A proposal approved event can send a customer a next-step message, while invoice paid can notify a project team member that work can proceed. New Contact can create the person in Mobile Message, and New Project can send an internal alert with the project name or site details. Mobile Message performs the selected action through Zapier, so Handoff stays focused on estimates, invoices and project management.

These focused Zaps are useful when timing matters. A client can receive a short acknowledgement after approving a proposal, a builder can be alerted after payment, and a new contact can be made available for later messaging. Each workflow runs in one direction from one Handoff event to one Mobile Message action. It does not imply a shared project record or automatic updates in both systems.
