Send every venue the same brief first
Venue proposals rarely line up. One quotes room hire plus a per-head menu, another a single package price, a third a minimum spend with a waived room fee. Comparing headline numbers means comparing different things. The fix starts before the quotes arrive: give every venue the same written brief, and ask for the contract terms (deposit, cancellation, guaranteed numbers) with the price, not after you have picked a winner.
- Date, start and finish times, plus access time for set-up and a sound check.
- An attendance range, not a single number, counting guests, speakers, staff and sponsors’ guests.
- The layout (banquet rounds, theatre rows, cocktail standing) and the running order.
- AV needs, including any hybrid element, and any dietary or cultural meal requirements.
- A request that every price is shown inclusive of service charge and tax, or clearly marked as exclusive.
Room hire versus food-and-beverage minimum spend
Venues charge for space in two main ways: a room-hire fee, or a food-and-beverage minimum spend, where the room is free if you spend at least the stated amount. Many proposals combine them, with a room-hire fee waived if the minimum is met.
That waiver is the part most often misread. A waiver that only applies when a minimum spend is reached is really a different offer, one that exists only in the scenario where you hit the minimum. So do not assume it. Price two scenarios side by side: minimum met and the room free, and minimum missed. What happens then depends on the contract: full room hire may be charged, the shortfall may be payable, or both.
- What counts toward the minimum: food only, or also drinks, AV, room hire, service charge and tax?
- Is it measured on the numbers you guarantee or on what is actually consumed?
- Does it apply per room, per session or per day?
- What is the full room-hire price if the waiver is lost?
Per-head menu prices, service charge and tax
A per-head price is only comparable once you know what it includes: courses, soft drinks, tea and coffee, any alcohol package and its duration, and how dietary alternatives are priced. Ask who the price covers. Speakers, your own staff and sponsors’ guests all eat, so count them even when they do not buy a ticket.
Then check service charge and tax. Whether a listed price already includes them varies by venue and by country, and sometimes by venue within one city. Some quotes mark prices as exclusive, with a plus sign or the word net, and add the charges at the end. Check every quote, and ask the venue to show the arithmetic for one line (listed price, service charge, tax, final price), because in some places tax is calculated on top of the service charge.
- Convert every price to one basis before comparing. Inclusive (what leaves your bank account) is the safest default.
- If your chamber can recover tax paid on purchases, the exclusive figure may be the true cost. Rules differ by country and organisation, so confirm with your accountant or the tax authority.
- If quotes arrive in different currencies, convert at one stated rate and note it.
- Check whether service charge and tax also apply to AV, room hire and extras.
AV, extras and the contract terms that cost you later
AV is where quotes diverge most. One venue bundles a projector, screen and microphones, another prices each item, a third requires its in-house supplier and charges a technician by the hour. A cheap room with an expensive mandatory AV package is not cheap. Never leave an extra as zero because the quote is silent: write “unknown”, ask, and replace it with the answer. A blank in a comparison sheet quietly becomes a free item.
Attrition is the gap between the numbers you guarantee and the numbers who attend. Many contracts bill the guaranteed covers even if fewer guests arrive, sometimes with an allowed reduction before a cut-off. Guarantee 80, see 60 attend, with no reduction allowed, and you pay for 80 meals. Treat the allowed reduction as part of the price. Deposits matter too: a chamber collecting ticket money close to the event may pay deposits long before it, so compare cash timing as well as totals.
- What the AV package contains, who operates it and for how many hours, and whether you may bring your own supplier.
- Hybrid, livestream or interpretation equipment, and the internet bandwidth to support it.
- Overtime if the programme overruns, and charges for early access or a late finish.
- Other extras: signage, flowers, power for displays, a registration desk, security, cloakroom, parking, corkage.
| Term | What to ask | Why it matters |
|---|---|---|
| Guaranteed numbers | When do final numbers lock? Can you reduce, by how many, and by when? | You pay for guaranteed covers whether or not guests arrive. |
| Increases | Can you add guests after the cut-off, at what price, and will the room still fit? | Late registrations may be turned away or charged differently. |
| Deposit schedule | How much, when, refundable or not, credited against the final bill? | Deposits may be due before ticket sales have covered them. |
| Cancellation terms | What do you owe at each stage, and is there a rebooking credit? | Cancellation cost can differ more between venues than price does. |
| Force majeure | Can you change the date, and who carries the loss if the event cannot go ahead? | A clause that looks standard can decide who bears the cost. |
Normalise every quote to a total and a cost per attendee
First check capacity. A venue that cannot hold your highest attendance level in your layout is out, whatever its price. Banquet rounds seat fewer people than theatre rows, and a stage, registration desk or buffet reduces capacity again, so ask for the figure for your layout, not the brochure headline.
Then pick two or three attendance levels (low, expected and high) from your own chamber’s past attendance at similar events. Fix one guaranteed number and run every venue through every level. The total is room hire (if charged in that scenario), plus food and beverage for the billable covers, plus AV, plus extras, all on the same service-charge and tax basis. The cost per attendee is that total divided by the number who actually attend.
The table below shows three made-up proposals, already converted to an inclusive basis. Every figure is a placeholder, not a real price.
| Item | Venue A | Venue B | Venue C |
|---|---|---|---|
| Room hire | 3,000, no conditions | 2,500, waived only if food and beverage spend reaches 7,000 | 1,800 |
| Food and beverage | 70 per head: set lunch, soft drinks, tea and coffee | 80 per head, same inclusions | 95 per head, same inclusions plus AV |
| AV | 600 package: projector, screen, two microphones | 1,200 package, in-house supplier required | Included in the per-head price |
| Minimum spend | None | 7,000 food and beverage (the waiver condition) | None |
| Service charge and tax | Included in prices shown | Excluded from listed prices; converted here using the charges stated on the quote | Included in prices shown |
| Guarantee and attrition | Pay for guaranteed number; no reduction | Reduction of up to 8 covers allowed before the cut-off | Pay for guaranteed number; no reduction |
| Capacity, banquet rounds | 110 | 100 | 90 |
What the example shows once you run the scenarios
The results table below runs each venue at three attendance levels with a guarantee of 80. Extra covers above the guarantee are charged at the same per-head price in this example.
Venue A is cheapest at the low and expected levels. Venue B is cheapest only at the high level, the one level where its minimum is met and the room is free. Its cost per attendee swings from 158 to 93, while Venue A moves from 153 to 108. Venue C is competitive at the first two levels but cannot seat the high case in banquet rounds.
The expected level hides a useful detail. Venue B’s food and beverage spend at 80 attendees is 6,400, only 600 short of its 7,000 minimum. If a drinks upgrade of 600 counts toward the minimum and your guests would value it, the waiver applies, the total falls to 8,200 and the cost per attendee to about 103, which beats Venue A. That holds only if the contract counts drinks toward the minimum, which is why the waiver must be priced as its own scenario and its conditions read closely.
Keep the sheet: it answers the board’s question about why a venue was chosen, and the cost per attendee is the number you carry into ticket pricing, covered in the separate guide in this library on running chamber events that make money.
| Attendance level | Venue A: total (per attendee) | Venue B: total (per attendee) | Venue C: total (per attendee) |
|---|---|---|---|
| Low: 60 attend | 9,200 (153) | 9,460 (158) | 9,400 (157) |
| Expected: 80 attend | 9,200 (115) | 10,100 (126) | 9,400 (118) |
| High: 95 attend | 10,250 (108) | 8,800 (93) | Does not fit: 95 exceeds capacity of 90 |
Where Chamberflow fits
Chamberflow has a venue sourcing tool for exactly this first step. Staff upload hotel or venue proposal PDFs, AI extracts the terms, and the app lays them out side by side so the totals can be compared: AI extracts, the app computes. Once a venue is chosen, each event has a live profit-and-loss view showing projected ticket and sponsor revenue against costs. Every AI action is logged, and a person approves before anything is sent or written back.
It does not negotiate with venues or pick one for you. Staff still decide which proposal to take, and should check the extracted terms against the original proposal before relying on them.
