Part of Trade show marketing procurement: a practical process
Vendor due diligence protects your trade show marketing budget
A practical checklist for trade show marketing vendor due diligence, covering risk, data, claims and contracts, plus a rubric to score exhibit suppliers.
- Set common evidence criteria and stop conditions before reviewing supplier presentations.
- Verify each bidder's identity, insurance, available capacity and responsibility for specialist work.
- Agree how enquiry data will be accessed, stored and processed.
- Trace physical supply dependencies and ask how delivery disruption will be handled.
- Request proof for performance promises and supplier-provided stand material.
- Tie payments to delivery, settle ownership and agree what happens if plans change.
Set the decision rules first
Decide how each offer will be judged before supplier presentations start, so confidence and polish cannot substitute for proof. Weight each criterion in line with your exposure, and set a minimum acceptable result for data handling and supply continuity before reviewing bids.
Use one rubric across every bidder. Include company and financial standing, insurance and health and safety, supply continuity, data protection, claim support, commercial terms, and relevant references. Ask suppliers to provide evidence against each category rather than relying on a broad capability statement. This makes differences visible without letting an impressive presentation dominate the decision.
Calculate a weighted result from the evidence, then apply the agreed stop conditions separately: a poor showing on data protection or supply-chain resilience should prevent approval even if other marks lift the total. If a supplier refuses evidence, record the weakest mark for that criterion rather than treating silence as neutral.
Verify who can deliver
Check the supplier's legal identity before treating its quote as comparable.
Match the registered company name to its Companies House register, review company filings for late accounts or abrupt director changes, and request current public and employer liability insurance certificates. Record expiry dates so the evidence remains current for the event.
Capacity deserves the same early scrutiny as legal standing. Ask for a build schedule that matches your stand and whether other shows fall within the same delivery period. A low price is not useful if no build slot is available, so log capacity alongside the quotation and confirm it before moving forward.
Pre-shortlist vendor checks
- Companies House name and number
- Filing historylate accounts, director changes
- Public liability certificate and expiry
- Employer liability certificate and expiry
- Build schedule for your stand size
- Other shows that fortnight
- Written data processing agreement
For work involving distinct specialist roles, name the supplier responsible for each stage before comparing bids. The tools and supplier guide helps identify which specialist is needed at each point, so the shortlist reflects the work required rather than the breadth of a sales pitch.
Set the rules for enquiry data
When a supplier handles enquiry data, find out how information is stored and who can access it. Under UK GDPR, your business remains the controller; a missing written processing agreement leaves a responsibility that a supplier's verbal assurances cannot remove.
Make written handling arrangements a condition of approval, not a detail to settle after choosing. For software providers, start with the data-flow question, then record where enquiry information travels, how it is stored and who can access it. Resolve any unanswered points before signing.
Follow the physical dependencies
Exhibiting relies on physical goods arriving in time, so ask about the vendor's own supply chain.
Find out where stand structures, graphics and AV kit are made, and what delivery contingency applies if a shipment is delayed. Those answers show whether the supplier understands dependencies before disruption reaches your build schedule.
Probe the supply chain
- Ask where structures are made
- Ask where graphics are made
- Ask where AV kit is made
- Identify delay risk per item
- Map dependencies with BSI MESH
- Plan contingency for disruption
Use a structured set of questions to compare suppliers' continuity plans. The BSI enterprise supply chain resilience guidance discusses mapping dependencies and planning for disruption. Use it to prompt questions of an exhibit supplier, keeping the review focused on continuity as well as price.
Ask for support behind promises
When a supplier promotes a footfall uplift or another performance result, ask what evidence supports it. A polished presentation does not establish a claim. Test the basis for each promise before using it in your evaluation or allowing supplier-provided wording to shape what appears on the stand.
Advertising claims in the UK must be honest and substantiated. Apply that standard to your own exhibition material as well as the vendor's pitch: responsibility for displayed copy or imagery remains with you, even when a supplier has provided it. Keep the supporting evidence with your review record so the basis for approval is clear.
Limit exposure when plans change
Check the commercial contract for payments linked to delivery milestones rather than calendar dates. A deposit may be normal, but paying most of the fee before the build starts exposes too much of the budget. Compare each payment date with the work it is meant to fund.
Set out ownership of artwork, CAD files and photography, so changing supplier later does not require buying back your own stand design. Clarify who carries costs if the organiser moves or cancels the event. The implementation planning guide can help phase a supplier change without losing build time.
For a comparable record, send the criteria with the brief and retain the evidence used for each decision. Supplier comparison methods can help organise the checks; the same record also makes it easier to explain why a supplier passed or failed the agreed conditions.
