Ironback
Dedicated AI Operations Specialist
You get a full-time, dedicated specialist embedded in your company. They are trained on your industry's specific needs, learn your team's names and workflows, and are managed by Ironback to ensure they stay current with the latest AI tools and best practices. This provides expert execution without the recruitment, salary, and management burden of a $120K+ in-house hire.
Automated Call Handling & Dispatch
AI voice agents answer after-hours and overflow calls 24/7, ensuring no call is missed. The system automatically texts back missed calls, triages emergencies, and can dispatch urgent jobs before your team starts their day. This eliminates lost leads and improves emergency response, capturing the 78% of callers who typically won't leave a voicemail.
AI-Powered Estimating & Quoting
Specialists use AI-assisted takeoffs and photo-based workflows to cut manual estimating time by 50-70%. This transforms a task that traditionally consumes a third of an estimator's week into a process that takes minutes, directly saving on salary overhead and accelerating quote turnaround to win more business.
Automated Documentation & Compliance
Paperwork is digitized and automated. Digital job forms replace clipboards, inspection reports auto-populate, and industry-specific compliance paperwork for OSHA or EPA is processed systematically. This eliminates manual data re-entry, reduces errors, and ensures critical documentation is never piled up or lost.
