Key Takeaways
- A 500-person produced conference typically has 25–40 active supplier contacts on show day — each needs to know when they arrive, where they go, and who they report to
- Vendor briefing documents (one per supplier category) are the most effective prevention against show-day confusion
- Load-in sequencing (which vendor arrives when, in what order) is the most critical operational document for show-day execution — it is rarely completed before the week of the event
- Payment terms must be confirmed in writing with all suppliers before they are engaged — verbal agreements on payment timing produce disputes at show-close
- A vendor contact sheet (all suppliers, their on-site lead, and their mobile number) distributed to the production team at load-in is a basic best practice that is frequently absent
The supplier matrix
A 500-person corporate conference has: venue (events manager, operations manager), AV company (production manager, FOH engineer, LD, video engineer, rigging crew), staging company (site manager, erection crew), catering (events manager, head chef, service supervisor), florist, printing and signage company, photographer, videographer, security company (supervisor + team), transport company, accommodation hotel (coordinator), registration desk software vendor, furniture rental, and plant/décor supplier. That is 14+ supplier categories, each with 1–5 on-site contacts. The production company is the single point of coordination — communicating with every supplier, resolving conflicts between them, and ensuring each supplier knows what every other supplier is doing.
Vendor briefing documents
A vendor briefing document is a one-page or two-page summary of what that specific supplier needs to know to deliver their component of the event successfully: the venue address, the load-in access route, the load-in window and their specific arrival time within it, the on-site contact they report to, the specific space or area they are responsible for, their power and communications requirements, and the key timings that affect their delivery (for catering: service times; for security: door open times; for AV: programme start time). These documents are generated by the production company at week 2, reviewed by each supplier and confirmed as understood. Suppliers who arrive at a venue without a briefing document are suppliers who were not briefed — and they will ask questions that cost the production team time on load-in morning.
Load-in sequencing
The load-in sequence determines which supplier arrives when, what space they occupy, and what their dependency on other suppliers' completion is. Structural staging must be complete before the AV is hung from it. Power distribution must be live before AV equipment is tested. Florists cannot access the tables until caterers have laid them. Photographers arrive after the set is production-complete but before the doors open. The load-in sequence is a dependency map, not just a schedule. It is generated by the production company, confirmed with all relevant suppliers by week 3, and updated as the load-in logistics are finalised by week 1. Load-in sequences that are issued on the morning of load-in are load-in sequences that were not generated by a production company that runs its operation this way.
