Three workflows that build themselves.

Wire them once. They run every day.

📝

Bid follow-up on autopilot

Bid sent 5 days ago, no reply? Mainframe pings the client over SMS with a scheduled walk-through link.

1. Procore push → 2. Twilio SMS → 3. Calendly slot → 4. HubSpot deal stage
📄

Change order → signed PO

Super flags scope change in the field. AI drafts the change order, prices it from your cost book, routes for signature.

1. Field note → 2. QuickBooks pricing → 3. DocuSign send → 4. Stripe deposit
🚚

Sub coordination

Framing done? Mainframe texts electrician, plumber, and inspector with the window. Confirms arrival, reroutes if weather hits.

1. Schedule trigger → 2. Google Maps ETA → 3. Twilio blast → 4. Reply capture
