Event agencies charge in one of five ways: a fixed management fee, a percentage of total event spend, a mark-up on third-party costs, a day rate, or a hybrid of these. No model is cheaper in itself. What differs is where the agency’s margin sits and how easy it is to see. The only fair way to compare bids priced in different ways is total cost of delivery per attending delegate.

What are the five event agency fee models?
| Fee model | How it works | Where the agency’s margin sits |
| Fixed management fee | One agreed fee for defined agency services | Inside the fee |
| Percentage of total spend | A set percentage of the whole event budget | Inside the percentage, which rises as spend rises |
| Mark-up on pass-through costs | Low or no fee; supplier costs are billed with a percentage added | In the mark-up on supplier invoices |
| Day rate | Days worked by each role, multiplied by a rate card | In the rate and in the number of days |
| Hybrid | A fee plus a mark-up or commission on some cost categories | Split between the fee and supplier costs |
What is a fixed management fee?
A fixed management fee is one price for a defined scope of agency work, such as strategy, creative, project management and on-site delivery. The client can see the agency’s margin clearly. The risk is scope: check what the fee assumes and what triggers a change request.
How does a percentage-of-spend fee work?
The agency charges a set percentage of the total event budget. It is simple to understand, but the agency earns more when the client spends more, so it has no financial reason to cut costs. The fee rises with every pound spent on venue, catering and production.
What is a mark-up on pass-through costs?
The agency quotes a low fee, or none, and adds a percentage to the supplier costs it bills on. This can make a bid look cheap on fees while carrying a high total margin. Always ask for net supplier costs and the mark-up percentage shown separately.
How do event agency day rates work?
Each role has a daily rate, multiplied by the days the agency estimates it will need. The rate is visible, but the number of days is the agency’s own estimate and is rarely capped. A low day rate with an uncapped estimate can cost more than a higher rate on a fixed plan.
Where else do event agencies make margin?
Whatever the fee model, ask each agency to declare these in writing:
- Venue and hotel commission: paid to the agency by the venue for the booking
- Supplier rebates: annual incentives from production, travel or accommodation suppliers
- Related-party suppliers: production or technology companies in the same group, billed as third parties
- Handling charges: per-invoice, shipping or booking fees
- Currency margin: overseas costs converted at a rate other than the rate actually paid
- Cash float: client deposits collected before suppliers are paid
These are legitimate when disclosed. They distort comparison when they are not.
Which event agency fee model is cheapest?
None of them. On most corporate events, venue, production, catering, accommodation and travel make up most of the spend. That means the agency’s buying skill affects the final cost more than its fee does. A low-fee bid can be the most expensive to deliver.

How do you compare event agency bids with different fee models?
Restate every bid as total cost of delivery (TCD) per attending delegate:
TCD per delegate = (F + P + M + E + X − R) ÷ D
- F: all agency fees
- P: third-party costs at net supplier price
- M: mark-ups and percentage fees
- E: expenses
- X: anything required but excluded, priced at the bidder’s own rate, otherwise at the highest price among the bids that included it
- R: commission returned to the client under the contract
- D: attending delegates
Leave out each agency’s own contingency and hold contingency on the client side. Then calculate at three delegate numbers (low, base and high) to see how each bid behaves when numbers move.
In Live Group’s worked example of four illustrative bids, the lowest headline price (£228,480) became the most expensive to deliver (£263,740) once its exclusions were priced. The bid that looked third-cheapest turned out cheapest, at £625 per delegate.
What should you ask an event agency about its fees?
- What are your net supplier costs, and what mark-up applies to each line?
- Which commissions and rebates will you receive on our spend, and are they passed back?
- Do you use any related-party suppliers?
- How many days does your estimate assume, and is it capped?
- What does your fee exclude that the event will need?
- How will you hold our deposits for supplier costs?
How does Live Group charge?
Live Group prices strategy, creative, content and management as fixed fees against a defined scope, built from a published day-rate card. Third-party costs are passed through at net cost, with our books open to the client. Any commission or rebate is declared and either passed back or offset against fees.

Many do. Venues and hotels often pay commission to the agency that books them. Ask whether it is kept, passed back or offset against fees.
It is simple, but it rewards higher spending. If you use it, pair it with a budget cap and open-book reconciliation.
It is everything the client pays to deliver an event, including agency fees, supplier costs, mark-ups and expenses, less any commission returned, divided by the number of delegates who attend. It makes bids priced in different ways comparable.
No. Contingency should be a client-held budget line, released against approved and priced changes, so agencies are not rewarded for leaving it out.
