Short answer
The 15 questions worth asking an AV & LED wall support vendor cover four things: who owns the work, what the price actually includes, what goes in writing before you pay, and who is in the hall during build-up. Judge the replies by shape rather than content — a name, a date, a document or a number is an answer, and anything that merely reassures you is not.
Key takeaways
- Tie each payment milestone to a deliverable you can inspect, and keep a balance payable after handover.
- Ask what the vendor would change about your brief. A supplier with no opinion is not reading it.
- Ask what your area can physically hold — at 36 sq.m the honest answer is about 11 visitors and 4 staff.
- Get the project manager's name, the crew size and the build-up shift hours in writing.
- Grade answers on specificity: a name, a date, a document or a number beats any amount of reassurance.
- Ask what the quote excludes, never whether everything is included — the second question always gets a yes.
How this interview works
The hard part was never the questions. Any vendor will tell you the work is in-house, the price is all-inclusive and their team will be there. What you need is a way of hearing the difference between a sentence that commits to something and a sentence that merely sounds right.
That is why each question carries two notes: the answer that should settle it, and the answer that should worry you. The underlying test never changes. Specifics can be checked; reassurance cannot, and an AV & LED wall support vendor who offers only the second has told you something useful anyway.
Work through the stages in order. Questions asked at the wrong moment get the wrong answers — pricing questions before the brief is understood produce a number the vendor has to defend rather than revise, and build-up questions asked after signing produce whatever is convenient rather than whatever was planned.
Before you shortlist: questions 1 to 4
These decide who is worth briefing at all. Ask them on a call, before any design or pricing conversation, because they are about the firm rather than about your project — and because the answers are much harder to tailor when the vendor does not yet know what you want to hear.
Underneath, they all probe the same thing — whether the firm owns the work or brokers it. Written for event managers, corporate communication teams and agencies running conferences, launches, dealer meets and public shows, this guide exists because that answer usually surfaces during build-up week, when it is far too late to act on.
01
1. Who will be my single point of contact, from brief through dismantle?
A good answer is a name, a role and a mobile number, plus confirmation that the same person is physically on site during build-up and show days. A bad answer is "our team" or "our coordination desk". Shared accountability is no accountability, and a contact who changes at handover means nobody carries the history of your decisions onto the floor.
02
2. How many jobs are in your production queue for my show week?
A good answer is a number, ideally with an unprompted note about which of them is largest — it tells you whether your stand is the priority or the filler. A bad answer is "don't worry, we'll manage", which is what a firm says when the queue is not theirs to see, or when they already know the answer is uncomfortable.
03
3. Can I see photographs of finished projects at my size, from a show you can name?
A good answer brings on-site photographs with the show, the city, the stall area and the year attached, including shots of the stand occupied by staff and visitors rather than empty at handover. A bad answer is renders only. A render proves somebody can design; only a photograph proves somebody can build, and the gap between the two is where most disappointment lives.
04
4. Can I visit the workshop or studio this week?
A good answer is a day and an address. A bad answer is any version of "later" — nearer the show, after the order, once the design is approved. The request is routine for anyone buying something fabricated, so reluctance to host it is itself the finding, and you get that finding before spending a rupee.
Stage 2 — while you are being quoted (questions 5 to 8)
Now you have two or three vendors working from the same brief. These questions are what make their numbers comparable, and they are the ones most often skipped because they feel adversarial. They are not — a vendor who answers them well is making their own life easier too, since an itemised scope is also their defence against scope creep.
The cost drivers for AV & LED wall support are not a secret — they are the list below. Rental by day; bundled with stall builds. A vendor who can rank those drivers for your specific brief is pricing the job. One who cannot is pricing a guess and hoping the variations cover the difference later.
- Show duration and number of event days
- Equipment size and specification (screen size, projector brightness or drone count)
- Content creation and programming time
- Rigging, power backup and technician crew size
- Permissions, venue rules and rehearsal time
01
5. Are transport both ways, installation, electrical fittings and dismantle inside this figure?
A good answer goes line by line, yes or no, without hedging. A bad answer is a general "yes, everything's included" — which is the reply this question always draws, and the reason to put it as four separate questions. These are the four scopes most often missing, none of them is optional, and all of them get bought at show-week rates when they surface late.
02
6. What would you change about this brief if it were your budget?
A good answer is an opinion: spend more on lighting, less on joinery, move the storage, drop the second message. A bad answer is "it's perfect as it is". A supplier with no view is either not reading the brief or not willing to risk the order by disagreeing, and neither of those helps you on the floor.
03
7. How many light fittings, and where exactly?
A good answer is a count and a set of positions — spots on the brand wall, track over the product, a backlit panel at the entrance. A bad answer is "lighting included". Hall lighting is designed for the aisles rather than for your stand, which makes the lighting count the line most responsible for whether the stand reads as funded or forgotten.
04
8. What is driving this price, and what would make it cheaper?
A good answer names the real drivers for your brief and then offers a trade: less custom joinery, a simpler finish, a reused frame, fewer graphic panels. A bad answer is a flat discount with no change to the scope. A number that drops on request without anything being removed means the first figure was padded, or the next one is thinner than it looks.
Before you sign: questions 9 to 12
These turn a conversation into a contract. Each one closes a gap that otherwise gets discovered on the floor, when the only options left are expensive. Ask them before the advance leaves your account, because afterwards you are negotiating from a weaker position with a shorter clock.
Note that none of these is about design or price. They are about documents, dates and authority — the three things that determine whether a stand gets built as agreed or as improvised.
01
9. What drawings will I approve, and by when, before anything is cut?
A good answer names dimensioned plans and elevations with finishes and lighting positions marked, and gives you a date for sign-off. A bad answer is "you've approved the render". A render is an impression; a drawing is an instruction. If what you signed has no dimensions on it, "this is not what we approved" is an argument you cannot win.
02
10. Will you dry-build the stand in the workshop before dispatch, and can I see proof?
A good answer is yes, with photographs or a video, panels numbered and circuits tested. A bad answer treats it as unnecessary. Where the first assembly happens decides whether build-up is assembly or problem-solving, and problem-solving in a hall costs hours you have not got.
03
11. What are the payment milestones, and what does each one release against?
A good answer attaches every instalment to something inspectable: a signed scope, approved drawings, the submission acknowledgement, a workshop dry build, handover of a working stand. A bad answer is a schedule of bare dates, or most of the money up front. Keep a meaningful balance payable after handover — it is what keeps a crew on the stand on show morning.
04
12. What happens if you are late?
A good answer is uncomfortable but specific: here is the slack in the schedule, here is who we call, here is what we would do. A bad answer is that it has never happened. You are not really looking for a penalty clause — you are looking for evidence that somebody has thought about the failure case before being inside it.
Last stage — the week that decides it (questions 13 to 15)
Save these for the fortnight before the show. By then production is finished and everything that can still go wrong is logistical. It is also the stage buyers most often skip, which is precisely why asking gets you an unpolished answer.
What the show finally has to deliver is an experience strong enough that guests film and share it, with a clear brand moment and a call to action timed in the show. These questions test whether anyone has planned for the hours in which that actually happens, because a stand still being assembled at ten in the morning on day one delivers none of it.
01
13. Who is on the floor during show days, and how fast can they reach my stand?
A good answer is a name, a location and a response time. A bad answer is a central number. Show-day problems tend to be small and urgent — a blown lamp, a loose panel, a screen that will not wake — and they only stay small if somebody is already in the building.
02
14. What is the build-up plan — arrival slot, crew size and working hours?
A good answer is a time, a number of people, a shift pattern, and the hour by which the stand will be finished and cleaned before doors open. A bad answer is "we'll be there from day one". Build-up windows are short and shared with every other exhibitor in the hall, so a vendor without a scheduled slot is planning to queue for the loading bay.
03
15. What is the backup if something fails during show hours?
A good answer is concrete: spares carried to site, a technician reachable within minutes, a named person on the floor through show hours, and a replacement path for anything that would stop the stand working. A bad answer is "nothing has ever failed". Lamps fail, laminate chips, screens drop signal and power trips — the only question is whether somebody planned for it.

Question, good answer, warning sign
The table below compresses the questions where the answer most often misleads. Each row is the same test: does the reply contain a verifiable specific, or does it contain comfort? Keep it open on the call rather than reading it afterwards.
| What you ask | A good answer sounds like | A warning sign |
|---|---|---|
| What do you need from me | A dated list of inputs | Nothing, we'll handle it |
| Can I see finished work | Photographs from a named show, with the stall area and the year | Renders only, or images with nothing attached to them |
| What would make it cheaper | A scope trade — simpler finish, fewer panels, a reused frame | A flat discount with no change to the scope |
| Who submits to the organiser | The documents, the person and the deadline | The organiser will let you know |
| What materials are quoted | Board thickness, finish and fire treatment, named | Premium quality, with no specification |
| What are the payment milestones | Each instalment tied to something you can inspect | A schedule of dates, with most of it up front |
| Who is on site at build-up | A name, a crew size and the shift hours | Our team will be there |
Across every row, the good answer is shorter and more specific than the warning sign. Length in an answer to a simple question is usually a sign that the specific is not available.
The size question most exhibitors never ask
Add one question to the 15 above, because it sorts designers from order-takers faster than anything else: how many people fit in my stand at once? A AV & LED wall support vendor who has thought about the show can answer it; one who has only priced the joinery cannot.
The sums are these: 10% of the area to storage up to 18 sq.m and 15% beyond it, 5% to a meeting corner — 20% if meetings are the point of attending — and the rest to display. Display divided by 2.5 gives simultaneous visitors; total area divided by 9 gives staff on duty.
Why it matters: footfall expectations and stand capacity are usually set by different people who never compare notes. If your campaign is built around a volume of visitors the stand cannot physically hold, the constraint is the stand, not the marketing — and that is a conversation to have at briefing stage, not on day one.
| Size booked | Usable display | Storage taken | Staff | Visitors it holds | Lead time |
|---|---|---|---|---|---|
| 9 sq.m | 7.6 sq.m | 0.9 sq.m | 2 | 3 | 3 |
| 18 sq.m | 15.3 sq.m | 1.8 sq.m | 2 | 6 | 3 |
| 24 sq.m | 19.2 sq.m | 3.6 sq.m | 3 | 7 | 4 |
| 54 sq.m | 43.2 sq.m | 8.1 sq.m | 6 | 17 | 5 |
| 72 sq.m | 57.6 sq.m | 10.8 sq.m | 8 | 23 | 5 |
Staff = area ÷ 9, minimum 2. Build weeks are 3 as a base, plus 1 from 24 sq.m and plus 2 from 54 sq.m, with a further 2 weeks for a premium finish and 2 for a double-decker.
When the answer is the decision
Some replies are not warning signs to weigh up — they are conclusions. The first group below are the failure modes specific to AV & LED wall support; if a vendor's answers point at any of them, you have learned what you needed to learn and the next call is to the second name on your list.
- Under-specified equipment that looks dull in a bright hall
- No rehearsal or technical run before doors open
- Missing backup power or spare units
- Content not built for the actual screen or surface size
- A discount offered the moment you hesitate, with nothing removed from the scope
- Reference images that cannot be tied to a show, a size or a year
- An advance requested before any scope document exists
- A delivery week offered in place of a dated production schedule
- Fabrication offered without drawings for you to approve first
- A material specification that says premium and names nothing
- No answer at all on dismantle, clearing or storage
The questions are easy to find. Reading the answers is the skill.
After the interview
Keep one page with the vendors across the top and the questions down the side. You are not scoring eloquence — you are looking for the empty cells, which are invisible in a phone call and obvious in a grid.
Then invert the exercise. Start from what the show has to deliver and ask whether these answers add up to it. A vendor can pass every question and still have no view on your outcome; that is a competent contractor rather than a partner, and worth knowing which you have hired.
- The build-up arrival slot, crew size and shift hours
- What the quote excludes, in writing and signed
- Who does the work, and the address where it happens
- The dismantle plan, and where reusable elements are stored
- The payment milestones and the deliverable behind each one
- Who submits the organiser paperwork, and the deadline
- What the vendor needs from you, and by when
Ask all three at once
Send all three vendors the same brief and the same questions: show name, city, dates, stall area, number of open sides, budget band, and two or three reference images with a line on what you liked about each. Identical inputs are what make the replies comparable, and how quickly and precisely a vendor answers before you have paid anything is the best available preview of how they will answer during build-up week.
Put the list to us and you will get written answers to all of it. Our own workshops, free design with a confirmed fabrication order, organiser drawings and approvals prepared for you, and a single project manager from the first brief to the last panel out of the hall.
Frequently asked questions
Should I ask about things that could go wrong?+
Yes, and the quality of the answer matters more than the content. A vendor who describes the slack in their schedule, the spares they carry and who they would call has thought about failure. One who says nothing has ever gone wrong has not.
When should I ask about build-up?+
A week or two before the show, once production is finished. Ask for the arrival slot, the crew size, the shift hours and the hour the stand will be finished and cleaned — not the hour build-up closes.
Should the answers be in writing?+
Yes. Scope, inclusions, exclusions, drawing dates, milestones and the named site contact all belong in the quote or the contract. A verbal answer is a recollection, not a commitment.
How do I know if my stand is the right size?+
Ask the vendor what it can hold. At 36 sq.m the arithmetic gives about 28.8 sq.m of display, room for roughly 11 visitors at a time and 4 staff on duty. If your footfall expectation is far above that, the constraint is the stand rather than the campaign.
What should I ask about the venue's rules?+
Ask for the height limit, whether rigging is permitted, the fire certification the organiser requires, and the date drawings must be submitted. Specific knowledge of one hall beats a claim to work in every city.
What if a vendor refuses to itemise the quote?+
Treat the refusal as the answer. Without line items you cannot compare two quotes, remove scope you do not need, or tell the difference between a cheaper vendor and a smaller scope.
Which question matters most?+
Who physically does the work. It decides who controls quality and who controls the date, and every other answer — pricing, drawings, site crew, backup plans — depends on it.
What is the best question to catch a sub-contracted build?+
"Can I visit the workshop this week?" A firm that owns production answers with an address and a day. Anything that defers the visit — after the order, nearer the show, once design is approved — is the answer by another route.
