A quote is not a design
The first thing to understand is that most AV proposals are price lists dressed up as plans. They tell you what equipment will be supplied and what it costs — but not why each item is there, how it's laid out, or whether it's the right call for your space. Reading one well means reverse-engineering the design from the line items.
What's commonly padded
Look for over-specified equipment — flagship gear in rooms that don't need it, more amplification or processing than the speaker count requires, and 'future-proofing' that's really just margin. Vague labor lines and large undefined 'allowances' are where budgets quietly expand after you sign.
Recurring service plans are worth scrutinizing too: some are genuinely valuable, others are baked-in revenue you're agreeing to indefinitely.
What's commonly missing
Padding is visible; gaps are not. The dangerous omissions are infrastructure: conduit and pathways, structured cabling, network capacity, equipment ventilation, and coordination with other trades. A quote can look complete and still leave out the rough-in that makes the whole thing possible.
Comparing quotes honestly
You can't compare two proposals that describe different scopes — which is exactly why integrators' quotes are so hard to evaluate against each other. The fix is a single, independent specification that every integrator bids against, turning a pile of incomparable price lists into a true apples-to-apples comparison.
This is the most common reason clients engage an independent consultant mid-project: to translate the quotes they already have before signing one.
