Most LA AV companies advertise free estimates. So do we — every quote we write is at no cost to the client and no commitment to proceed. But the framing of "free estimate" can be a tell. The companies that lean hardest on the "free quote!" sales angle are often the ones whose business model depends on recouping that cost somewhere else in the engagement.
Here is where that cost actually shows up.
1. Scope creep on the day-of.
The pattern: the quote covers the basics — PA, lighting, video — at a tight number. Then on load-in day, the venue rep mentions a power requirement that "wasn't in the original scope." Suddenly there is a generator rental, a power tie-in fee, an electrician on the call sheet. The quote has grown 15-25% in the 48 hours between contract signing and load-in.
Why it happens: the original quote was deliberately scoped lean to win the bid. The "missing" elements are not actually surprises — they are scope items the vendor knew would come up but chose not to call out in the original number.
How to spot it before contract: ask explicitly about power, permits, COIs, content provision, post-event archive deliverables, and overtime. If any of those are not on the line-item quote, ask why. A vendor who quotes them in writing pre-contract has nowhere to hide later.
2. Change orders at "industry rates."
The pattern: a small scope change happens during pre-production. The vendor sends a change order priced at "industry rates" — which turn out to be 30-50% above the equivalent line items in the original quote. The client signs because the alternative is delaying the show. The change order is profit recovery.
Why it happens: the original quote was priced under cost, expecting that change orders during pre-production would bring the engagement into profit. The vendor needs the change orders to happen.
How to spot it: ask for the change-order rate card before signing the contract. If a vendor cannot tell you in writing what a change order will cost — what an additional cabinet, an additional engineer, an additional day will be priced at — they are reserving the right to set those numbers later.
3. Post-event surprise charges.
The pattern: the show happened, the engagement looked successful, and 2-3 weeks later an invoice arrives with line items that were "necessary on the day" — additional rigging because the venue's rigging plot did not match the drawings, additional crew hours because the load-out went long, additional gear because something was substituted at the last minute. Total surprise: 10-20% over the original quote.
Why it happens: the day-of execution costs more than the quote allowed for, but the vendor does not raise it at the time. They wait until the invoice cycle, when the client has less leverage.
How to spot it: insist on day-of approval for any scope deviation. A reputable vendor will text or email a same-day scope change notice with the dollar impact, ask for approval, and proceed only after acknowledgment. Vendors who tell you "we'll figure it out and reconcile after the show" are setting up the post-event surprise.
4. Sub-rental markups.
The pattern: the vendor does not own a specific piece of gear (a niche LED pitch, a specialty camera body, a touring-scale truss). They sub-rent it from a partner and mark it up 30-50% on the quote without disclosing the sub-rental source or the underlying cost.
Why it happens: sub-rental markups are how brokers make their margin. A vendor who owns nothing and sub-rents everything is essentially running this play on every line item.
How to spot it: ask which line items are owned vs. sub-rented. Ask for the sub-rental source on any line item that is sub-rented. A vendor who owns their core rig and discloses sub-rentals transparently is operating on a different business model than one who refuses to break this down.
The real question.
The right question is not "is the quote free?" — every quote should be free. The right question is "does this vendor make money from the quote, the show, or the surprise?"
A vendor whose business model is built on the surprise is structurally incentivized to keep the original quote artificially low and recover the difference through scope creep, change orders, post-event invoicing, and sub-rental markups. They will be cheapest at the moment you sign. They will not be cheapest at the moment you write the final check.
A vendor whose business model is built on transparent execution writes the quote that matches the invoice. The original number is the final number. Scope changes are documented, approved, and priced at known rates. Sub-rentals are disclosed. The "surprise" is engineered out before it can become one.
The free estimate is not free. The only question is when you pay for it.
