SMART HOME / AV ESTIMATING.

## Smart Home and AV Estimating Built for St. Louis Integrators St. Louis runs a mixed residential and commercial AV market. You're quoting home theaters in Ladue and Frontenac one week, then structured cabling for a corporate tenant build-out in Clayton the next. The scope swings are wide. Your bid process shouldn't slow you down either way. Estimate.Pro takes you from a walkthrough to a sendable bid in 8 minutes. Walk the job, capture measurements with live AR on supported devices, and let the AI scope engine convert your notes into a line-item estimate. You review, price, and send. ### What Makes AV Estimating Harder in St. Louis St. Louis City and St. Louis County operate under separate permitting authorities. A low-voltage rough-in permit in St. Louis City goes through the City of St. Louis Building Division, while the same job in Chesterfield, Kirkwood, or Ballwin falls under municipal or county jurisdiction. Requirements differ and permit timelines differ. You need to build those costs into every bid before you submit it. Older housing stock in the city — much of it pre-war brick construction — adds wall-fishing time that suburban tract work does not. A distributed audio rough-in in a 1925 bungalow in Tower Grove or the Hill can run 30-40% more labor than the same spec in a newer Wildwood build. If your estimate template doesn't account for structure type, you're eating that delta. The Missouri consumer electronics and integration market also concentrates around the west St. Louis County corridor. Competition from regional dealers who bundle installation with equipment sales means your bid clarity is a differentiator. Itemized scopes with named equipment, control standards, and labor breakdowns win jobs that a single-line quote loses. ### How Estimate.Pro Handles AV Scope The AV trade module covers home theater, distributed audio/video, control systems, structured cabling, surveillance, access control, and smart lighting. Each category has its own material and labor line items tied to your saved cost workspace. You set your St. Louis labor rates once. Every estimate pulls from that baseline. AR measurement runs on supported devices using ONNX-assisted detection. For camera or photo captures on unsupported hardware, measurements are marked as estimates so you know what to verify on site. You're not guessing which numbers are solid. For larger integrated projects — a full Crestron or Control4 commission, a multi-zone audio install across a new build — the Elite tier adds Stripe Connect invoicing and export workflows so billing follows the bid without re-entering data. Stripe Connect platform fee is 0% on Pro+ plans. ### Permits, Codes, and Local References Missouri does not have a statewide low-voltage contractor license, but St. Louis City and several St. Louis County municipalities require a master electrician or registered low-voltage contractor to pull permits for structured wiring and AV rough-ins. Confirm local license requirements before you bid any permitted scope. For any AV work that intersects with electrical — lighting control panels, motorized shading tied to home automation, EV charger integration with smart home systems — Missouri follows NFPA 70 (NEC) and St. Louis City enforces the 2020 NEC edition. County municipalities vary; some are still on 2017. Check the adopted code edition with the AHJ before specifying equipment. ANSI/TIA-568 governs structured cabling standards. HDMI 2.1 and HDBaseT specs matter when you're quoting 4K/8K distribution. Name the standard in your scope. It reduces change-order disputes. ### Pricing Estimate.Pro is free to start — no credit card required. The Pro plan runs $39 per seat per month. Elite is $79 per seat per month and adds Stripe Connect and invoice export. Crew is $399 per month flat for unlimited seats, which works for shops running multiple integration crews across the metro. There is no platform fee on Pro+ plans. On the Free tier, Stripe Connect carries a 3% platform fee. If you're quoting AV jobs in St. Louis and still building estimates in a spreadsheet or copying last month's bid, you're leaving margin on the table and spending time you don't have. Estimate.Pro is built for how integration work actually gets scoped and sold.
