LapseHawk is compliance and paperwork software for general contractors, subcontractors, landlords and property managers in the US. Users upload files or phone photos, or connect Gmail, Outlook, Google Drive or OneDrive, and LapseHawk uses AI to read certificates of insurance, bills, invoices, W-9s, lien waivers, permits, proposals, contracts, leases, violation notices and inspection reports. Each document is filed to the right vendor, project, building or unit. Every certificate of insurance is checked against the user's own requirements, including limits, additional insured, waiver of subrogation and certificate holder, with reminders 30, 14 and 7 days before it lapses. Permits and inspections sit on one calendar with reminders before they are due. Open building violations are checked automatically from public records in New York City, all of New Jersey and 38 more cities and counties, and an official link is given where a city does not publish open cases by address. For contractors, LapseHawk drafts monthly pay applications in the AIA G702/G703 layout, builds a monthly invoice binder per project, exports bills as a CSV file for accounting software and drafts Gantt schedules with AI. A property management mode adds properties, units and leases, rent roll import, work orders, rent invoices and building compliance checklists. LapseHawk runs in any web browser and as an Android app, with Admin, Project manager and Viewer roles. Every plan includes every feature.
