The AV Integrator's Guide to Markup vs. Margin (And Why You're Probably Losing Money)

This is one of those things that should be simple. Markup. Margin. They both involve percentages and profit. How different can they be?

Different enough that if you're confusing them — and a lot of integrators do, especially early on — you're making less money than you think on every single project. Not a little less. Thousands less. And you won't notice until year-end when the books don't add up and you're wondering where the profit went.

Let's fix that permanently.

The difference, in plain English

Markup is how much you add on top of your cost. The denominator is your cost.

Margin is how much of the sell price is profit. The denominator is the sell price.

Same item, different denominators, completely different numbers. This is the entire problem — people say "30%" without specifying 30% of what, and the math diverges fast.

Let's use a real example. You're quoting a Crestron CP4-R control processor. Your cost from your distributor is $2,000.

If you apply a 30% markup:

• Sell price = $2,000 x 1.30 = $2,600
• Profit = $600
• Your actual margin = $600 / $2,600 = 23.1%

If you want a 30% margin:

• Sell price = $2,000 / (1 - 0.30) = $2,000 / 0.70 = $2,857
• Profit = $857
• Your actual markup = $857 / $2,000 = 42.9%

That's a $257 difference on a single line item. On a Crestron processor. Now multiply that across every piece of equipment on a $50K conference room buildout — displays, DSPs, amplifiers, touch panels, cabling, mounts — and you start to see the problem.

Why this matters on real AV projects

Let's scale this up. You're quoting a $50,000 commercial AV project — a couple of conference rooms, a huddle space, maybe a lobby display. Standard bread-and-butter work for a small integrator.

If you're applying a 30% markup across the board and thinking you have 30% margin, here's what actually happens:

• What you think: $50,000 x 30% = $15,000 profit
• What you actually have: 23.1% margin = $11,538 profit
• The gap: $3,462 you thought you had but don't

That's one project. If you're running 20 jobs a year at that scale — and most small integrators are running at least that many — you're $69,240 short of where you thought you'd be. That's a technician's salary. That's a van payment and insurance for the year. That's real money that never existed because the math was wrong from the start.

The cruel part is you won't feel it on any single project. Each one feels "close enough." It's the aggregate that kills you.

The markup-to-margin conversion table

Bookmark this. Print it. Tape it to your monitor. Every AV integrator should know these numbers by heart.

The formulas, if you want them:

• Margin from markup: Margin = Markup / (1 + Markup)
• Markup from margin: Markup = Margin / (1 - Margin)
• Sell price from cost + margin: Sell Price = Cost / (1 - Margin)

Common AV markup ranges

These are ballpark figures based on what we see across the industry. Your numbers will vary by market, project size, client relationship, and whether you're buying direct or through distribution. But if you're wildly outside these ranges, it's worth asking why.

• Displays (Samsung, LG, Sony): 25-35% markup (20-26% margin). Competitive category — clients can Google retail prices easily.
• Control systems (Crestron, Extron, AMX): 30-40% markup (23-29% margin). More proprietary, harder for clients to price check.
• Audio (Shure, QSC, Biamp): 30-40% markup (23-29% margin). DSPs and processing tend toward the higher end.
• Cabling, connectors, mounts: 50-100% markup (33-50% margin). Low unit cost, high labor-to-material ratio. This is where you should be making money.
• Labor (installation): 40-80% markup (29-44% margin) over your fully loaded cost. Varies enormously by market.
• Labor (programming): 60-150% markup (38-60% margin). Specialized skill, higher rate is justified.

The important thing isn't hitting these exact numbers. It's knowing what your actual margins are on each category, not just what your markups are.

Where integrators lose money without realizing it

The markup vs. margin confusion is the foundation problem. But it opens the door to a handful of specific profit leaks that show up on nearly every project:

Accessories and infrastructure

That HDMI cable costs you $8, you sell it for $12, and you move on because it's "just a cable." But you needed 47 of them, plus wall plates, plus conduit adapters, plus patch panels. Suddenly the infrastructure section of your quote is $3,000 at cost and you've barely marked it up because you were focused on the big-ticket items. This is the category where 50-100% markup is standard — and justified — because of the handling, inventory, and installation labor involved.

Labor hours

You estimated 16 hours to install the audio system in that boardroom. It took 24 because the ceiling plenum was a mess, the electrician wasn't done, and the client changed the speaker layout on day two. Those 8 extra hours at your fully loaded cost didn't get billed, didn't get change-ordered, and just ate directly into your margin. Under-estimating hours — especially programming and commissioning time — is the single most common margin killer for small integrators.

Freight

A QSC Q-SYS Core 110f, two Shure MXA920 ceiling mics, an amplifier, 14 speakers, and a rack full of Crestron gear. That's not a pickup order from your local distributor. Freight on a mid-sized project can easily run $800-$1,500. If you forgot to line-item it or under-allocated the percentage, that's coming straight out of profit. Standard rule of thumb: 3-8% of equipment cost for freight, depending on project size and how far you are from your distributor.

Scope creep

"While you're here, can you also add a display in the break room?" Sure — but did that become a change order, or did you just nod and absorb it? Scope creep is margin erosion disguised as good customer service. Every addition that doesn't get documented and priced is profit you're giving away.

How to protect your margins

None of this is complicated. It just requires discipline and visibility.

• Track margins per line item, not just per project. A 30% blended margin on a project can hide a 5% margin on displays and a -2% margin on labor. You need to see where you're making and losing money at the line level.
• Set margin floors by category. If your floor for equipment is 20% margin and a line item comes in at 15%, that should be a visible flag before the quote goes out.
• Review margins before you send. Every quote, every time. A two-minute scan of your margin column before hitting send catches problems that would cost thousands to fix after the fact.
• Use visual indicators. Numbers in a spreadsheet column all look the same. Color-coded margin indicators — red for below target, amber for watch-it, green for healthy — let you spot problems at a glance without reading every number.
• Build change orders into your process. When scope changes, clone the quote, issue a CO number, and price the addition properly. Don't absorb it.

Stop guessing, start seeing

The markup vs. margin distinction isn't academic. It's the difference between knowing your actual profit and guessing at it. And in a business where 5-10 points of margin can be the difference between a good year and a bad one, guessing isn't a strategy.

QuoteAV shows your margin per line item, per room, per system, per quote — in real time as you build it. Red means you're below your target. Amber means watch it. Green means you're good. No formulas to maintain, no manual calculations, no hoping you got the math right. You see your actual margin on every line before the quote leaves your hands.
