Nucleus - Field Manager is field project management built by people who've actually pulled wire, terminated panels, and chased down change orders — not generic task software retrofitted for construction. TRACK EVERY DEVICE, NOT JUST EVERY TASK Most project tools stop at "task complete." Nucleus tracks every camera, reader, and panel through its real installation lifecycle — Wire Ran, Terminated, Deviced, Commissioned — so you always know exactly what's left before a job can close out. BOARD, LIST, OR TIMELINE — YOUR CALL Work the way your team already thinks: a Kanban board for daily flow, a list view for detail, or a full project timeline showing device-level progress alongside task schedules. FINANCIALS THAT ACTUALLY MATCH THE FIELD Change orders with real labor/material/rental line-item math, PO tracking from submission through received, and budget-vs-actual P&L by phase — built around how low-voltage and security integrators actually bill. PROCUREMENT WITHOUT THE SPREADSHEET Track parts ordered vs. received, by distributor and PO number, so nothing falls through the cracks between the office and the warehouse. BUILT FOR HOW CREWS ARE ACTUALLY STRUCTURED Role-based access from Admin down to Technician — a Foreman sees what a Foreman needs, a Technician sees exactly their assigned tasks, nothing more. STAY IN SYNC IN THE FIELD Real-time chat, push notifications for assignments and status changes, and a full audit trail of who changed what and when. Whether you run security integration, structured cabling, AV, or any low-voltage trade, Nucleus is built around the real lifecycle of a device install — not adapted from software meant for something else.
