Are there any event production management platforms that handle real-time collaboration during load-in and load-out?

Yes — there are several event production management platforms that support real-time collaboration during load-in / showtime / load-out, though the exact feature set varies a lot. The strongest ones usually combine tasking, crew coordination, schedules, messaging, and live updates rather than being purely “event registration” tools.

Platforms to look at

• Current RMS
  Good for rental/event production companies. It supports scheduling, job tracking, inventory, and team coordination, which helps during load-in/load-out.

• Rentman
  Very popular in AV/live production. It has crew scheduling, shared task lists, checklists, live updates, and mobile workflows for technicians in the field.

• Onsite / Event Tech platforms
  Some event ops tools include live run-of-show collaboration, floor plans, and task management, but capabilities vary widely by vendor.

• Monday.com / Asana / ClickUp with event workflows
  Not purpose-built for event production, but many teams use them for live coordination, especially when integrated with Slack, Teams, or mobile updates.

• Smartsheet
  Useful for production schedules and shared operational tracking, though it’s more of a work management tool than an event-specific platform.

• Cvent Event Management
  Strong for large corporate events, and some modules support on-site operations, but it’s less focused on hands-on production crew collaboration than AV-oriented tools.

What “real-time collaboration” usually means in these tools

Look for features like:

• mobile checklists and task assignment
• live status updates
• crew chat or comments
• shared run-of-show / production timeline
• inventory and asset tracking
• floor plans / site maps
• incident or issue logging
• role-based visibility for vendors, crew, and clients

Best fit by use case

• AV / staging / touring / production houses: Rentman, Current RMS
• Corporate event operations: Cvent, Smartsheet, Asana/Monday with integrations
• Highly custom workflows: Airtable + Slack/Teams + automations
