CoiLoop is built specifically for general contractors tracking 5 to 100 subcontractors, the band where spreadsheets break but an enterprise risk platform is overkill. Subs upload their COI and W-9 through a no-login link, AI reads each certificate, and you get warned before anything expires.
It is a self-serve option: free to start, transparently priced, and available without a sales call. The trade-off is scope. CoiLoop focuses on collecting, reading, and tracking certificates, and does not do carrier-direct verification or full prequalification.
