Step 1 · Events
Choose the event types and vendor categories
Start with a defined audience, such as weddings, private parties or community events. Separate catering from performance services and describe what each listing must explain. Hosts should be able to understand whether a caterer serves their guest count or a performer offers the style they need.
Tradly: Tradly’s multi-vendor marketplace supports vendor accounts and separate dashboards for managing their listings.

Step 2 · Briefs
Give hosts a consistent event inquiry template
Ask hosts to share date, venue area, guest size, event schedule, dietary needs where relevant and the service they want quoted. Tell vendors how to ask follow-up questions and what a complete response should include. Avoid implying a vendor is available until they confirm the date.
Tradly: Tradly buyer-seller chat lets hosts and vendors exchange questions about event requirements and service scope.

Step 3 · Review
Set vendor and service information standards
Decide what details you review before publication, including service area, sample menus or performances, setup requirements and cancellation terms. For food vendors, clarify that hosts must discuss allergies and food safety directly with the caterer. Do not claim a vendor is certified unless you verify the evidence.
Tradly: Tradly vendor onboarding includes sign-up, verification and approval steps; ratings and reviews cover sellers and listings.

Step 4 · AI
Use AI to shape event briefs and answer host questions
Hosts may ask what details are needed for a catering quote or how to find a performer for a particular event style. Train an agent on your categories and inquiry template. As operator, ask an AI assistant to review new vendor listings or summarize repeated host questions, then confirm event details with vendors.
Tradly: Tradly Agent Builder trains agents on your own pages and notes. Tradly MCP connects the marketplace to Claude, ChatGPT, voice agents and custom agents.

Step 5 · Launch
Test one catering and one performance inquiry
Invite a few vendors from each category and ask test hosts to prepare realistic event briefs. Check that the first replies cover scope, date confirmation and any important follow-up. Fix confusing listing or inquiry guidance before adding more event categories or paid promotion.
Tradly: Tradly includes ratings and reviews on sellers and listings, and subscriptions and promotions includes featured listings and promotions.

Questions people ask
Can hosts book a vendor directly through Tradly?
The supplied feature catalog does not specify general event booking calendars or date availability. Use an inquiry and confirmation process, or verify a suitable booking integration before promising automatic reservations.
What should an event inquiry include?
Include event date, venue area, guest size, schedule, service type and any requirements vendors need to quote. For catering, tell hosts to discuss allergies and menu details directly with the provider before confirming.
Can AI help run an event vendor marketplace?
Yes. An agent trained on your categories and inquiry guide can explain what information hosts should provide when contacting a caterer or performer. Through Tradly MCP, an owner can review new vendor listings or summarize host questions, then confirm availability with providers.
