Step-by-Step Guide
Define Vendor Requirements
Before reaching out to vendors, document exactly what you need from each category. For catering, specify guest count, dietary requirements, service style, and menu preferences. For AV, list equipment needs, room dimensions, and technical requirements. The more specific your requirements, the more accurate your quotes will be—and the easier it is to compare proposals.
Create a vendor requirements template you can reuse. Over time, you'll refine what information matters most for each vendor type.
Research and Shortlist Vendors
Build a shortlist of 3-5 vendors per category through referrals, venue recommendations, and online research. Check reviews, view portfolios, and verify insurance and licensing. For critical vendors (catering, AV), visit their previous events if possible. Preferred vendor lists from your venue often indicate proven reliability.
Ask venues for their "required" vs "preferred" vendor lists. Required vendors are non-negotiable; preferred vendors just get priority but you can bring your own.
Create and Distribute RFPs
Your Request for Proposal should include event overview, detailed requirements, timeline, budget range (if comfortable sharing), evaluation criteria, and response deadline. Give vendors 1-2 weeks to respond. Include your contact information for clarifying questions—good vendors will ask thoughtful questions that show they care about getting it right.
Include a site visit option in your RFP timeline. Vendors who see the space firsthand provide more accurate proposals.
Evaluate Proposals and Interview Finalists
Create a scoring matrix with weighted criteria: price (20-30%), experience (20%), references (15%), creativity (15%), responsiveness (10%), and insurance/compliance (10%). Schedule calls or meetings with top contenders. Ask about their backup plans, team assignment, and how they've handled past challenges. Trust your instincts—you'll be working closely with these people.
Always call references. Ask specifically: "Would you hire them again for your next event?" The hesitation (or enthusiasm) tells you everything.
Negotiate Contracts
Don't accept the first proposal as final. Negotiate on price, payment terms, cancellation policies, and included services. Key contract elements: detailed scope of work, payment schedule (avoid paying 100% upfront), cancellation terms, force majeure clause, insurance requirements, and liability limits. Have legal review contracts for large events.
Ask for itemized pricing. It's easier to negotiate when you can see exactly what you're paying for each component.
Establish Communication Protocols
Create a communication plan with each vendor. Designate a single point of contact on both sides, establish check-in schedules, and use shared documents for evolving details. Set up a production schedule that shows when each vendor needs final information (guest counts, floor plans, run of show) and when they'll deliver their components.
Use a shared project management tool like Monday.com or Airtable where all vendors can see timeline updates relevant to their work.
Coordinate Vendor Load-In
Create a detailed load-in schedule showing when each vendor arrives, where they set up, and how long they have. Sequence vendors logically: lighting before decor, decor before catering, etc. Conduct a pre-event walkthrough with key vendors to finalize placement, power access, and any last-minute adjustments.
Build buffer time between vendor load-in slots. Someone always runs late, and back-to-back scheduling creates cascading delays.
Manage Day-Of Execution
On event day, have vendor contact information readily accessible. Assign a point person to each critical vendor relationship. Conduct a pre-event briefing to confirm timing, troubleshoot issues, and ensure everyone has what they need. Stay calm when problems arise—your demeanor affects vendor performance.
Create a "vendor emergency kit" with backup supplies: extra tablecloths, extension cords, gaffer tape, and petty cash for last-minute needs.
Conduct Post-Event Reviews
Debrief with each vendor within a week of the event. Discuss what worked, what could improve, and gather their observations about the event flow. Document performance for future reference. For vendors who exceeded expectations, write referrals and consider them for preferred vendor status on future events.
Send a thank-you note to vendors who performed well. The goodwill pays dividends when you need a favor on a future event.
Common Mistakes to Avoid
Choosing vendors solely on price
Factor in experience, reliability, and references. The cheapest option often costs more in stress and subpar results. Value matters more than cost.
Vague contracts without detailed scope
Document every deliverable, timeline, and specification in writing. Assumptions lead to disputes. If it's not in the contract, it's not guaranteed.
Last-minute vendor changes
Lock in vendors early and communicate final details on schedule. Late changes disrupt planning and may incur rush fees.
Micromanaging experienced vendors
Hire experts, give clear requirements, then let them execute. Constant interference undermines their ability to deliver their best work.
No backup plans for critical vendors
Have contingency contacts for catering, AV, and entertainment. Ask your primary vendors about their own backup procedures.
