An association planner sends a 40-page PDF two months before their conference. It lists every session, meal, room, setup, AV need and contact for three days. The cover says "Event Specification Guide," and the planner asks the venue to review it and confirm. For a venue used to weddings and parties, the document can feel overwhelming.
The structure of an ESG is predictable once you have seen one. It is the planner's master record of the event, and read properly, it becomes the most useful document a venue receives.
What Is an Event Specification Guide?
An event specification guide (ESG) is a document prepared by the event planner that sets out all the requirements for an event in one place, including the schedule, attendance, contacts, billing and the details of every function such as room, setup, food and beverage and AV. It is shared with the venue and key suppliers so everyone works from the same specifications. Many planners use the industry template from the Events Industry Council, often called the APEX ESG.
Why Planners Use an ESG
Large events involve many functions, rooms and suppliers. An ESG gives the planner one place to record every requirement and one document to share. It reduces errors, keeps suppliers aligned and creates a record if questions arise.
For the venue, the ESG is the most complete statement of what the client expects. Reading it carefully and confirming it back prevents surprises on the day.
It also shows how the planner works. A detailed ESG with clear authorizations and billing instructions usually means a planner who will hold the venue to the same standard, and who will notice when the venue meets it.
The Usual Sections
ESGs vary, but most follow a similar structure, especially those based on the industry template.
- Event overview, with name, dates, goals and expected attendance
- Key contacts for the planner, the venue and suppliers
- Billing instructions and who may authorize charges
- Arrival and departure patterns, and room blocks where relevant
- Function schedule and a detailed sheet for each function
The function sheets are the heart of the document. Each one covers a single session, meal or reception, with its date, time, room, setup, attendance, food and beverage, AV, signage and special notes.
Some ESGs add sections on exhibits, shipping and receiving, security, accessibility, VIPs and emergency plans.
Read the whole document once before you act on any part of it. Details in the overview, such as a VIP arrival or a sponsor's branding rules, often change how you set a room described forty pages later.
How the ESG Maps to Banquet Event Orders
The ESG is the planner's document, and the banquet event order (BEO) is the venue's working version of each function in it. Each function sheet in the ESG becomes, or informs, a BEO.
When you receive an ESG, use its function schedule to create or update BEOs for each function, with the room, times, setup, menu, AV and staffing. Cross-reference each BEO to the ESG function so changes can be tracked. If the ESG and a BEO disagree, raise it with the planner immediately.
What the Venue Should Confirm Back
Planners expect the venue to review the ESG and confirm it, or note any issues. Do this in writing by the date the planner sets.
- Rooms assigned to each function, with capacity for the setup
- Times, including setup and teardown, and any overlaps
- Menus, counts and dietary meals for each meal function
- AV and power for each function, and who provides it
- Billing, authorized signers and master account details
Flag anything you cannot deliver, any room that is too small for the setup, any timing that does not allow turnover and any missing details. Planners prefer to hear about problems early.
Handling Changes
ESGs change. Counts rise or fall, sessions move, menus are adjusted. Ask the planner to send revised versions with changes marked and a version date.
Update BEOs promptly and confirm changes back. Keep every version, since the final ESG and BEOs together are the record of what was agreed. Discuss the final version at the pre-con meeting with all departments.
Answering an ESG at a Smaller Venue
Smaller venues can handle ESGs well with a clear process. Assign one person to own the ESG, read it in full, and break it into tasks for each area, such as catering, AV, operations and billing.
Create a simple response checklist that you use for every ESG, and keep a template for your confirmation letter. After a few events, ESGs become routine.
If a section asks for something your venue does not offer, such as an on-site business center or a hotel room block, say so plainly in your confirmation and suggest an alternative. Planners would rather adjust early than discover the gap at check-in.
Build Your ESG Response Process
Write a short procedure for receiving an ESG (who reviews it, how BEOs are created from it, how confirmations are sent and how changes are tracked) and share it with your team. Keep a sample ESG on file for training. The next time a planner sends one, your team will know what to do.
A venue that answers the ESG well earns the planner's trust before the event begins.
Frequently Asked Questions
Who creates an event specification guide?
The event planner usually creates the ESG and shares it with the venue and suppliers. Many use the industry template from the Events Industry Council. The venue reviews it and confirms details back.
What is the difference between an ESG and a BEO?
The ESG is the planner's master document for the whole event, covering every function. A BEO is the venue's operational document for a single function, with room, setup, menu and timing. Each ESG function usually maps to a BEO.
When should a venue receive the ESG?
Planners often send the ESG several weeks before the event, with updates as details change. The timing depends on the event's size and the planner's process. Agree on deadlines for the ESG and the venue's confirmation.
What is the APEX ESG?
It is a standard ESG template developed by the Events Industry Council's APEX initiative. It gives planners and venues a common format for event specifications. Many associations and corporate planners use it.
