Your AV Proposal Looks Impressive. But What Are You Actually Buying?

The short version

• When three proposals for the same project land $43,000 apart, the vendors often aren't bidding the same job.
• An equipment list tells you what boxes you're buying. It doesn't tell you whether those boxes will solve your problem, or what's been left out. The brand on it may reflect what the vendor carries as much as what you need.
• Read the exclusions and assumptions first. That's where surprises, and change orders, tend to live.
• You don't have to be technical to judge a proposal. If a vendor can't explain it plainly, that's on the explanation, not on you.

Three proposals, one project

Say your school needs a new sound system for the gym. You ask three companies for proposals, and here's what comes back:

• Proposal A: $35,000
• Proposal B: $52,000
• Proposal C: $78,000

Which one is right? Maybe none of them.

That spread doesn't have to mean anybody's overcharging. It may mean each company answered a slightly different question. "We need a new sound system in the gym" can be read three honest ways:

• A replaces the speakers and reuses the existing amplifier, mixer and wiring.
• B adds wireless microphones, a new processor and some new cable.
• C quotes an entirely new system, plus lift rental, programming, staff training, an assistive listening system and an extended service plan.

None of them is necessarily wrong. They just aren't bidding the same job. The cheapest might leave you paying for the rest later. The most expensive might include things you don't need, or it might be the only one that actually solves your problem.

You can't tell from the price. You can tell from reading what's underneath it.

This isn't about catching anybody. Good contractors write proposals fast, often from limited information, and they have to make assumptions to put a price on the job. Your job is to find those assumptions before you sign.

What an equipment list tells you, and what it doesn't

Some proposals are all hat and no cattle: a handsome cover page, pages of model numbers, and not one sentence about your actual problem.

Most AV proposals include a bill of materials, or BOM. It lists every piece of equipment with model numbers, quantities and prices. It looks thorough, and specific numbers feel precise. But precise isn't the same as right.

An equipment list is a grocery list, not a recipe. You can buy every ingredient on it and still end up with a mess if nobody wrote down what dinner was supposed to be.

An equipment list shows you:

• what equipment is included;
• how many of each;
• what each item costs.

It doesn't show you:

• whether that equipment fits your space and your goals;
• where each piece goes and how it's aimed;
• how many hours it takes to install and set up;
• the cable, mounts, power and network connections it needs;
• who programs it, tunes it and trains your staff;
• what's been left out, and who's responsible for it.

That programming line deserves a word. Many modern systems have a small computer in the middle: a digital signal processor that manages the sound, or a control system behind the touch panel and buttons. It does nothing until somebody programs it. Programming is real work, and it should show up as a line item or be clearly listed as included. If it's not in there anywhere, ask who's doing it.

Reading a proposal, line by line

Most proposals have the same handful of parts, even when they're labeled differently. Here's what each one is and what to look for.

What is included in “miscellaneous”?

Every installation requires more than the equipment listed on the proposal. Cables, wiring, connectors, mounting brackets, hardware, and other installation materials all contribute to a complete, functioning system.

A line labeled “miscellaneous materials” isn’t automatically a red flag. However, the proposal should clearly identify what’s included and account for the materials necessary to complete the installation. That might be a defined materials schedule or a clearly explained allowance—not necessarily a separate price for every connector.

You shouldn’t discover halfway through a project that essential cabling, mounting accessories, or other required materials weren’t included in the original price.

Ask: Does the proposal cover the cabling, wiring, mounting hardware, connectors, and installation materials needed to deliver a fully operational system? If something is excluded, where is that documented?

Proposal phrases that deserve a second look

These phrases show up often. They aren't tricks; they're shorthand. But each one marks a spot where the price can move after you sign.

None of these is a red flag by itself. "By others" is completely normal. It only becomes a problem when "others" turns out to be you and nobody mentioned it.

Why that brand? Follow the chain

Plenty of buyers walk in knowing a well-known audio brand by name. That's fine. But if your budget is moderate, a big name can eat it up fast, and other manufacturers may be a better fit for the money. A good proposal should tell you why a brand is right for your budget, not just that it's a name you recognize.

Here's something that isn't always said out loud: sometimes the brand on a proposal is there because of the vendor. Not every dealer or contractor can sell every brand. Each one carries the lines it's authorized for, knows and can support, and some lines pay a better margin than others. None of that makes a contractor dishonest. It does mean the brand you're looking at may reflect their catalog as much as your needs.

It also helps to know how equipment reaches you. Depending on the manufacturer and the purchasing arrangement, the route can look different:

• Manufacturer → Dealer → Customer
• Manufacturer → Dealer → Contractor → Customer
• Manufacturer → Distributor → Dealer/Reseller → Contractor → Customer

Not every transaction involves every intermediary. Each business may provide legitimate value through inventory, logistics, technical expertise or customer support. Those roles have costs, and different purchasing arrangements can affect the final price. More intermediaries don't automatically mean an inflated price; the question is whether the proposed equipment and services meet your needs.

Understanding how equipment reaches you can help explain differences in pricing. But the most important question remains whether the proposed equipment and services are appropriate for your project.

Markup vs. margin, in plain math

These two words get used like they mean the same thing. They don't, and the difference takes thirty seconds to learn.

Say a contractor buys a speaker for $1,000 and sells it to you for $1,250. They made $250.

• Markup compares that $250 to what they paid: $250 ÷ $1,000 = 25% markup.
• Margin compares that $250 to what you paid: $250 ÷ $1,250 = 20% margin.

Same dollars, two different percentages.

Why should you care?

• If a contract says "cost plus 15%," that's a markup. Know what "cost" includes before you agree to it.
• If someone says "we only make 20%," it's fair to ask which one they mean. A 20% margin is a 25% markup.
• Margin isn't the enemy. A contractor has to make a fair living, or they won't be around when you need warranty work. A price too thin to be healthy can come back later as change orders or slow support.

You usually can't see a contractor's cost, and you don't need to. Comparing box prices line by line only gets you so far. The bigger differences between proposals often come from what's included, which is where the next step comes in.

Comparing apples to apples

Procurement folks call this bid leveling. It just means lining proposals up so they're answering the same question, and you can do it with a pencil.

Put the things that matter to you down the side and the proposals across the top. Mark each box Included, Not included or Unclear. Here's how it might look for our three gym proposals. The entries are an example, not a real project.

Then do two things:

1. Send each vendor its "Unclear" and "Not included" items in writing, and ask for a price or a straight answer. Same questions to everybody.
2. Cross off what you don't need. Maybe an optional service plan isn't worth it to you. Other items, such as assistive listening, may be required by accessibility standards. Confirm those obligations before deciding what to remove.

Once everybody's answering the same question, the gap often shrinks, or at least starts to make sense. Sometimes the "expensive" proposal turns out to be the only complete one.

If you haven't asked for proposals yet, there's an even better fix. Write down what you need in plain words, and hand the same page to every vendor. One page in your own words beats three companies guessing.

Communication is part of the design

A customer can be their own biggest advocate—or their own worst enemy. Sometimes the difference comes down to words that were, or weren’t, spoken.

Two organizations can purchase identical equipment and have completely different experiences. One may have experienced technical personnel capable of managing portions of the project. Another may need a contractor to handle everything from installation through training.

Neither situation is inherently better. But those differences matter when developing a proposal.

An overconfident buyer might unintentionally give a designer or contractor the impression that certain technical capabilities or resources are available when they aren’t. On the other hand, a customer who is uncomfortable admitting what they don’t understand may remain silent rather than ask an important question. Both situations can create expensive misunderstandings.

Silence isn’t your friend when you’re dealing with something you don’t understand.

A qualified designer or deployment coordinator has a responsibility to understand the customer’s needs, ask meaningful questions, and explain the proposed solution in language the customer understands.

The customer has a responsibility, too: communicate your expectations, explain what resources you actually have, and speak up when something isn’t clear.

You don’t need to become an audio engineer to purchase a sound system. You do need to participate in the conversation.

Good communication doesn’t guarantee a project will be free of problems. But it can prevent many of the problems that arise when people make assumptions instead of asking questions.

Clarify. Clarify. Clarify. Never assume.

What happens after installation?

Before signing, ask what happens after the equipment is installed. Who programs the system? Who verifies that it performs as intended? Who trains the people who will use it? And if something needs adjustment six months later, who do you call?

Equipment warranties, installation workmanship, commissioning, training, and ongoing technical support are separate responsibilities. For design integrity and protection of your investment, each should be clearly addressed in writing. If something isn’t documented, request clarification before signing. Never assume a service is included simply because you believe it should be.

A good proposal should establish clear expectations for everyone involved. Asking questions doesn’t mean you distrust your contractor. It means you’re giving both parties the opportunity to identify misunderstandings before they become expensive problems.

A service doesn’t necessarily have to be included in the price. Its inclusion, exclusion, or separately quoted cost should be clear.

Does it actually solve your problem? Five tests

You don't need to know what a signal processor does to run these.

1. It restates your problem in your words. If you said "parents can't hear the announcements at volleyball games," the proposal should say that, not just "furnish and install audio system."
2. Every major item has a job you can understand. Point at any big line and ask, "What does this do for us?" You should get one plain sentence back.
3. It says how everyone will know it works. Look for a test or walk-through before final payment that's tied to your goal, not just "installed and operational."
4. The exclusions are listed, and you know who covers each one. A proposal with no exclusions at all more likely means nobody wrote them down than that there aren't any.
5. You could explain it to your board in two minutes. If you can't yet, ask the vendor to help you get there. That's part of their job.

If a vendor can't explain it plainly, that doesn't mean you aren't technical enough. It means it hasn't been explained well enough yet.

Before You Sign

A proposal should leave you confident about what you're purchasing, what is included, and who is responsible for delivering it.

If you're uncertain, ask questions. Request clarification in writing. Make sure the answers become part of your agreement.
