How to manage event vendors: tenders, quotes and call sheets

Ask a producer where an event lives and the honest answer is everywhere. Quotes arrive as email attachments. Negotiation happens on the phone, off the record. Work orders get written at midnight from a doc template. Every vendor has its own chat group, and the call sheet drifts a little with every message.

Here is a cleaner way to run the vendor side of an event.

Step 1: Write one brief per category

Before you ask anyone for a price, write a short brief for each category: stage and rigging, sound, lighting, catering, security, and so on. Each brief should state:

• Scope, as specifically as you can.
• Dates and load-in and load-out windows.
• The venue and access constraints.
• Your budget range, if you are willing to share it.
• What a bid must include: amount, timeline and a cover note.

The same brief to every vendor means bids you can actually compare.

Step 2: Decide who gets to bid

Some categories suit an open call. Others suit a few trusted vendors. Choose per category: public or invite-only. Invite a mix of vendors you have used before and new ones worth testing.

Step 3: Compare bids side by side, with history

Price alone is a poor guide. Put each bid next to:

• Years in the trade.
• Your rating of them, and jobs they have done with you.
• How quickly they reply, which predicts how they behave on the day.
• Whether the bid fits the budget.

Step 4: Negotiate on the record

Counter-offers made by phone are forgotten or disputed. Run negotiation in rounds, and write each one down: their bid, your counter, their revised figure, the agreed scope. If you drop the second delay tower to meet a price, that should be on the record.

Step 5: Award cleanly

When you pick a vendor:

• Close the other bids in that category, and tell those vendors.
• Issue a work order with scope, dates and the agreed amount.
• Create a payment record so finance knows what is owed and when.

Step 6: Run load-in from one call sheet

Build a single call sheet with every vendor slot from load-in to load-out. Keep it as the one version everyone works from, and change it in one place when the schedule moves.

Step 7: Close out the morning after

Pay vendors against their work orders, note how each one performed, and update your ratings for next time. This is how your vendor list gets better with every show.

A simple timeline

• 3 weeks out. Tenders go out.
• 2 weeks out. Bids compared, work awarded.
• Show day morning. Load-in by the call sheet.
• Morning after. Thank-you messages and payments.

What we are building

Assembly is an event management system we are building for agencies and promoters. It is coming soon and is not yet available. The plan is one record per event covering both the crowd (ticketing by tier, QR check-in with live headcount, an attendee list you keep) and the crew (public or invite-only tenders, logged negotiation rounds, awards that generate a work order and payment record, and a shared call sheet). A person on your team will approve anything that goes out to attendees or vendors.

Mistakes that cost the most

• Briefing vendors differently. If one stage company quotes for two delay towers and another for one, you are comparing different jobs.
• Agreeing scope changes verbally. The vendor remembers the price. You remember the scope. Neither is written down.
• Leaving losing bidders hanging. Vendors you never told are less keen to bid next time.
• Multiple call sheets. A PDF in email, a version in chat and a printout at the venue will not match by show day.
• Paying from memory. Without a work order and payment record per vendor, finance is guessing what was agreed.
