The Business Case for Centralised Event Procurement

This page is written to help a procurement manager make the internal case for consolidating event procurement. Use it to structure your own business case — and download the template to build it out.

The current-state problem

In most organisations, event spend is significant but unmanaged. It has grown organically, department by department, without ever being treated as a category. The result is a set of connected problems that each carry cost.

Fragmented expenditure

Event spend is spread across marketing, HR, sales, the executive office and regional teams, with no single owner. No one sees the total, so no one manages it. This is the root of the forgotten category problem.

Lack of spend visibility

Because spend is fragmented and inconsistently coded, procurement cannot answer basic questions about the category. Without visibility, there is no benchmarking, no consolidation and no evidence for change.

Supplier duplication

The same categories — venues, caterers, AV, agencies — are sourced repeatedly by different teams, multiplying onboarding, diluting leverage and creating compliance gaps. Consolidation is the direct remedy.

Inconsistent contracting

Different teams sign different terms. Cancellation and attrition clauses vary, exposing the organisation to avoidable risk that only surfaces when plans change — as many discovered in recent years.

Lost negotiating leverage

Scattered spend has weak leverage. Ten small relationships each command worse terms than one large one. Aggregating volume through coordinated negotiation recovers that leverage.

Administrative workload

Duplicated sourcing, onboarding and contracting consume time across the business — a hidden cost that rarely appears in any budget but is real nonetheless.

The potential solution

The solution is to treat events as a managed procurement category — applying event category management to bring visibility, leverage, governance and efficiency to spend that currently has none.

Proposed operating model

Most organisations adopt a hybrid model: central sourcing frameworks, benchmarking, consolidated suppliers and reporting, while local teams retain choice over the events themselves. Our guide to centralised vs decentralised event procurement sets out the options; an outsourced partner can provide the capability without new headcount.

KPIs

Reporting

Central reporting makes the value visible and sustains the case over time — turning a one-off business case into an ongoing, evidenced story of managed spend.

Stakeholder adoption

The business case must address adoption, because a model teams route around delivers nothing. Success depends on involving event teams early, preserving local choice, and making the sanctioned route genuinely easier than going it alone — the surest defence against maverick spend.

Implementation roadmap

1. 1
   Phase 1 — Visibility (weeks 1–6)

   Spend analysis and a baseline report. Sizes the opportunity and evidences the case.
2. 2
   Phase 2 — Quick wins (months 2–3)

   Benchmark and renegotiate obvious overspend; consolidate clear duplication.
3. 3
   Phase 3 — Framework (months 3–6)

   Stand up the preferred supplier programme and governance.
4. 4
   Phase 4 — Embed (ongoing)

   Drive adoption, refine KPIs and report value continuously.
