SubVerify turns subcontractor compliance from a stack of expiring paperwork into a system that watches itself. General contractors get a live picture of which subs are covered, which documents are about to lapse, and which paperwork is still missing, before a gap becomes a liability. Warren & Sabb Services built the platform that makes that promise operational.
SubVerify (live at getsubverify.com) is a subcontractor compliance management platform built for general contractors. It tracks certificates of insurance, contractor licenses, W-9s, OSHA certifications, and bonds in one place, and it keeps that record current with automated expiration alerts, project-level tracking, and a self-service portal where subcontractors upload their own documents. The product Warren & Sabb built takes a task most contractors run on spreadsheets and email reminders and turns it into software that holds the whole picture.
The problem
A general contractor is only as covered as the least-covered subcontractor on the job. Every sub is supposed to carry current insurance, the right licenses, and the documentation that proves it. The trouble is that those documents expire on their own schedule, and nobody on a busy site is watching the calendar for thirty different vendors. A certificate of insurance lapses on a Friday afternoon, work continues through the weekend, and by the time anyone notices on Monday morning the contractor has been exposed for three days without knowing it.
The conventional system for catching this is a spreadsheet and good intentions. Someone in the office keeps a tab of every sub, their COI, their license, their expiration dates, and chases the renewals by email. It works until it does not. Endorsements go unverified, a policy gets validated once and never checked again, and the link between compliance status and payment stays loose: a sub can get paid while their coverage has quietly gone stale. Industry context underscores the stakes here. Across the United States, uninsured subcontractor claims are estimated to cost roughly $2.4B a year, the average uninsured-incident settlement runs about $54K, and compliance staff can spend 5+ hours a week just chasing documents. Those are industry-wide figures, not results SubVerify produced, but they describe the cost of the gap the product is built to close.
Underneath the manual tracking sits a structural problem: the people who hold the documents are not the people who track them. The contractor needs the paperwork current, but the subcontractor is the one who renews the policy and holds the certificate. Without a shared place for that exchange, every renewal is a round of phone calls and forwarded PDFs, and the contractor is left reconstructing compliance status after the fact instead of seeing it in real time.
The approach
Warren & Sabb built SubVerify as a single source of truth for subcontractor compliance: a dashboard that holds every sub, every document type, and every expiration date in one current view. Certificates of insurance, contractor licenses, W-9s, OSHA certifications, and bonds all live in the same record, organized so a contractor can see at a glance who is covered and who is not. The point is to replace the spreadsheet with a system that does not depend on someone remembering to update it.
The engine of the product is proactive rather than reactive. Automated expiration alerts fire before a document lapses, not after, so the Friday-to-Monday gap closes before it opens. Project-level tracking ties compliance to the jobs it protects, and a subcontractor self-service portal moves the work of uploading and renewing documents to the party who actually holds them. The contractor stops chasing paperwork and starts reviewing a status board; the subcontractor gets a clear, standing request instead of a scramble. This is the build pattern Warren & Sabb applies repeatedly: take a process that depends on manual vigilance and slow human cycles, and turn it into software with dashboards, alerts, and a clear division of who does what.
The same logic runs through our work on compliance tracking, where the goal is always to surface the data that matters in real time and remove the dependence on a single person remembering to check. If you want the longer explanation of what the product does and why it exists, our notes on what SubVerify is and on tracking certificates of insurance and license expirations walk through the mechanics in detail.
A single screen lists every subcontractor with a color-coded status for each document type, certificate of insurance, license, W-9, OSHA certification, and bond, so the contractor sees who is fully covered, who is expiring soon, and who is missing paperwork. This is a representative description of the kind of view the platform provides, not a screenshot.
An upcoming-expirations panel flags documents nearing their lapse date and triggers automated reminders, while the subcontractor self-service portal lets each sub upload renewed documents directly against the open request.

The outcome
In production, SubVerify changes the shape of compliance work from reactive to proactive. Instead of discovering a lapsed certificate after the fact, the contractor is alerted before it expires; instead of reconstructing status from a spreadsheet, they read it off a live dashboard; and instead of chasing every renewal by hand, they let the self-service portal route the work to the subcontractor who holds the document. The lapse gap closes, endorsement and document validation has a place to live, and compliance status becomes defensible documentation a contractor can stand behind.
We present this as the operational pattern the build produces, not as conversion or revenue figures Warren & Sabb measured, and the industry statistics above are context for the problem rather than outcomes SubVerify generated. The work we point to is the build itself: a manual, vigilance-bound process turned into software that tracks, alerts, and documents on its own.
