Start with the job, not the agency label
Event agency can describe very different businesses. Identity publishes services spanning brand experience, production and strategic advisory. C2events describes event management alongside healthcare meetings and delegate support. FIRST describes both full-service partnerships and embedded specialist talent.
Those service menus demonstrate why a shortlist needs a defined job. An agency’s ability to deliver a brand activation does not by itself establish the fit for a regulated professional meeting. Ask for relevant evidence of the work you actually need rather than a general showreel.
Who will deliver the work?
Ask who owns the brief day to day, who attends planning meetings and who can approve changes on site. Establish which activities are delivered internally, through named partners or through suppliers selected later. None of these models is inherently wrong; an undisclosed division of responsibility is the problem.
Request a responsibility schedule covering content, registration, production, venue liaison, accessibility, supplier coordination and reporting. It should make the handovers visible. Where your team supplies something, state when it must arrive and what happens if it changes.
How does the price work?
Ask whether the commercial model is a fixed project fee, a retainer, time-based fees, supplier mark-ups or a mixture. Request a clear distinction between agency remuneration, third-party costs, allowances and contingency. Ask how rebates or commissions are treated.
Then give competing agencies the same assumptions. An apparently cheaper proposal may exclude rehearsals, registration support or post-event reporting included elsewhere. A good comparison makes those differences explicit instead of treating the totals as like-for-like.
What does a change cost?
Agree the point at which a concept is approved and the method for approving changes afterwards. Identify who is authorised to spend and how a revised scope will be recorded. Discuss cancellation and postponement obligations before a supplier is committed, not after a date changes.
Ask what material you receive at handover: editable creative files where agreed, attendee-data exports, supplier information and the evidence behind the final report. Ownership and access should be written down rather than inferred from who paid the invoice.
What will count as success?
Give the agency a business outcome and ask how its proposal contributes to it. A sales meeting, member congress and product launch need different evidence. Agree measures you can actually collect, how they will be interpreted and who will receive the report.
Ask for references relevant to that brief and check the scope of the work behind each case study. Our directory descriptions are source-backed service summaries, not endorsements or independent verification of agency performance.
