One system for the full contractor job lifecycle — estimates, scheduling, field work, and invoicing — with offline-first mobile support.
Cinderblock is a job-management and field-service platform for contractors and trade businesses — general contractors, plumbers, electricians, HVAC technicians — replacing manual paperwork, spreadsheets, and phone calls with one system covering the full job lifecycle from first customer request through final invoice.
Office staff can build estimates, schedule crews, and track job costs in real time, while field technicians work offline-first on mobile, capturing photos, forms, and time entries that sync automatically once they're back online — keeping billing, scheduling, and field documentation in sync without manual reconciliation.
