What’s the Difference Between a Vendor and a Supplier?

Updated on August 3, 2026 | Written by Rachella Thomas

In the events industry, vendor and supplier are often used interchangeably. In most day-to-day event planning, both simply mean a third-party business providing a product or service for your event.

However, the terms are sometimes used differently. Supplier tends to describe businesses providing the core services or infrastructure behind an event, while vendor is more commonly used for smaller, specialised or attendee-facing businesses.

There’s no universal rule, and terminology varies between events, venues and organisations. But understanding the distinction can make event contracts, venue requirements and supplier communications a little easier to navigate.

The Distinction

• Event Suppliers (The Core Infrastructure): Planners often use the word ‘supplier’ for major, B2B infrastructure companies. These are long-term partners essential to the event's framework. They work primarily B2B (work directly with the planner).

  Examples: Venues, large-scale audiovisual (AV) production companies, staging contractors, main caterers, and staffing agencies.

• Event Vendors (The Specialized/Public-Facing Sellers): The word ‘vendor’ often refers to smaller businesses, transactional services, or external entities that set up a booth to sell directly to attendees. They mostly work B2C (interact with the event guests or attendees).

  Examples: Food trucks at a festival, photo booth operators, independent florists, or artisan market stalls.

How do I manage them properly? Once you start working with vendors and suppliers, The Vendor Checklist You Actually Need shows you how to source the right information and make sure it reaches the right people across your event plan.

Preferred vs. Exclusive Partners

When booking an event space, you will quickly learn that venues classify vendors and suppliers into two strict categories:

• Exclusive Partners: The venue forces you to use these specific companies. You have no choice. If you want catering or AV, you must use their designated exclusive supplier. If you bring in an outside company, you will face heavy penalties or contract termination.

• Preferred Partners: The venue provides a curated list of recommended businesses they trust. You may bring in your own outside vendor, but choosing from the preferred list often waives certain "outside vendor fees" or security deposits.

In-House vs. External Third Parties

This distinction drastically changes your profit margins and communication lines:

• In-House: The service is owned or directly managed by the venue itself (e.g., the venue's own kitchen staff or built-in AV system). It is bundled into your main contract, meaning fewer invoices to manage but less room to negotiate custom pricing.

• External: Independent businesses you hire separate from the venue. They require their own individual contracts, separate point-of-contact management, and separate payments.

Contractors vs. Suppliers

Planners often confuse who falls into which legal bucket, which affects tax and liability structures:

• Suppliers/Vendors: Provide a tangible asset or a wrapped commercial service (e.g., a floral package, a lighting rig, a stage).

• Contractors: Provide temporary labor or specialized independent skills directly to your planning agency (e.g., a freelance event coordinator, an independent stage manager, or a hired graphic designer).

What Does This Mean for Event Planners?

In practice, whether someone calls a business a vendor or a supplier usually matters far less than understanding the arrangement.

Is the business contracted by you or the venue? Are they preferred or exclusive? Are they providing infrastructure, selling directly to attendees, or working as an independent contractor? And, importantly, who manages them?

Once you clarify those distinctions, the terminology becomes much easier to navigate.
