COIs, W-9s, and lien waivers without the subcontractor chase.
SubLien uses AI to parse ACORD 25s, sends vendors secure upload and signing links, and keeps reminding them until the documents are complete.
The repetitive compliance work that slows projects down.
Before a sub starts work, you need the W-9 and COI. During billing and closeout, you need the right waiver signed. SubLien keeps those loops moving without a PM manually chasing every email.
Parse COIs with AI
Read ACORD 25s, extract limits and expirations, then flag gaps against your configured requirements.
Chase vendors automatically
Send secure upload and signing links, then keep reminding subs until the document is in.
Keep evidence organized
Store W-9s, signed waivers, COI reviews, timestamps, consent, and audit events with the vendor record.
Pre-work COI and W-9 intake. Waiver follow-up when signatures are due.
SubLien is first a compliance hub. Procore teams can add project/vendor sync and side-panel context, but vendor collection works even without a PM system.
Automation where it helps. Human review where it matters.
Simple plans for document compliance.
Every tier includes W-9 tracking, COIs, lien waivers, reminders, audit exports, and optional Procore connection.
Stop chasing compliance docs by hand.
We'll help you test COI parsing, W-9 collection, and lien waiver reminders on a real vendor workflow.
