What is Assembli Event Management Portal?
Assembli is a B2B event management portal that connects event organizers with vendors and exhibitors. It guides participants through multi-phase form submissions, manages required documents (COI, W9, contracts), tracks compliance deadlines, and gives admins full control over onboarding, approvals, and event logistics, all in one place.

Key Features
Assembli streamlines the entire vendor and exhibitor onboarding lifecycle for events. Vendors complete a structured three-phase workflow: Participation, Logistics, and Finalized Plans (with e-signature) guided by admin-configured, per-event forms with conditional logic.
The platform handles document uploads and tracks expiration dates for critical items like Certificates of Insurance, blocking participation when documents lapse. Admins can:
Build custom form templates with reusable question sets
Review submissions with notes and feedback
Export data to CSV and monitor email logs
Organizations can manage teams with role-based access (admin, editor, viewer). In-app notifications and automated email alerts keep all parties informed at every stage of the event cycle.
