§ Why ev charger install pros in St. Louis use Estimate.Pro
THE BID ENGINE.
## EV Charger Estimating Built for St. Louis Contractors
St. Louis is moving fast on EV infrastructure. MoDOT's EV corridor buildout along I-44, I-55, and I-70 is pulling commercial charging work into the metro, and residential installs are climbing alongside rising EV registrations in St. Louis County and the city proper. If you're bidding Level 2 home chargers in Ladue one day and DC fast-charger rough-ins at a West County retail center the next, your estimate process needs to keep up.
Estimate.Pro is built for that pace. Median time from walkthrough to sendable bid: 8 minutes.

### Why EV Charger Estimating Is Different Here
**Panel capacity is the first variable.** Most St. Louis–area homes were built before 1990. A significant share still carry 100-amp services. Before you touch a NEMA 14-50 or hardwired Level 2 unit, you're often scoping a panel upgrade or load calculation under NEC Article 625 and the 2020 NEC as locally adopted. Estimate.Pro's EV workflow walks you through service ampacity, dedicated circuit length, and conduit run in sequence — so you capture the panel upgrade in the same estimate, not as a change order.
**St. Louis City and County have separate permit jurisdictions.** A job on the city side files through the City of St. Louis Building Division. Cross the border into unincorporated St. Louis County and you're dealing with the Department of Public Works. Municipalities like Kirkwood, Webster Groves, and Creve Coeur each have their own building departments with their own fee schedules. Estimate.Pro lets you tag the AHJ per project so your permit line item reflects the right number before you send the bid.
**Utility coordination adds time.** Ameren Missouri serves most of the metro. DC fast-charger installs often require a utility notification or service upgrade request that adds lead time. Build that coordination cost into your overhead lines — Estimate.Pro's material and labor workspace holds your saved rates so you're not rebuilding from scratch on every job.

### What the App Does for You
**AR-assisted site measurement.** Walk the garage or commercial bay with your phone. On supported devices, ONNX-assisted live AR measures panel-to-charger distances and flags conduit run length automatically. Camera and photo measurements are marked as estimates so you know what to verify.
**NEC 625 scope generation.** The AI scope builder outputs line items aligned to NEC Article 625 (electric vehicle charging systems) — dedicated branch circuit, disconnect requirements, GFCI protection where required, and load calculation notes. You edit, you approve, it goes out.
**Saved material cost workspace.** Lock in your current pricing for EVSE units, wire, conduit, breakers, and panel hardware. When copper prices move — and they do — update once and every new estimate reflects it.
**Stripe Connect invoicing.** Elite tier connects your estimates directly to invoiced payments. No separate invoicing tool. Platform fee is 0% on Pro+ plans.
