EV Charger Installation Invoice Template (Free)

By ShowTheReceipts · Updated

Short answer

An EV charger installation invoice needs the charger unit and who supplied it, the circuit and conduit run with its length, breaker and panel work as separate lines, the permit and inspection fee passed through, and any drywall, trenching, or core drilling itemized. Copy the template below, or use software that carries the approved quote straight into the invoice.

Essential line items on an EV charger installation invoice

A professional Level 2 EV charger installation invoice serves as an official electrical safety inspection record under NEC 625 compliance, proof of load calculation, and tax credit rebate verification:

  • Electrical Contractor Licensing Header: Business name, logo, physical office address, phone, email, Master Electrician license number, state electrical contractor license, and liability insurance details ($1M+ policy).
  • Customer & Service Address Metadata: Client name, phone, installation property address, panel location (Garage, Basement, Exterior Wall), and completion date.
  • EV Charging Unit Metadata: Charger brand, model, maximum continuous charging amperage (32A, 40A, 48A, or 80A), NEMA 14-50 plug vs. hardwired connection, and unit supplier (Contractor-Supplied vs Customer-Supplied).
  • NEC 220 Load Calculation & Load Center Work: Electrical panel load calculation verification, 50A or 60A 240V double-pole breaker installation, or subpanel feeder installation.
  • Circuit Wiring & EMT/PVC Conduit Run: Linear feet of #6 AWG THHN copper wire in 3/4” EMT metallic conduit, schedule 40 PVC conduit, or 6/3 NM-B Romex cable.
  • 200A Panel Upgrade or Smart Load Shedder: 100A to 200A main service panel upgrade or smart energy management load-shedding device (DCC-9 or SimpleSwitch) for tight electrical panels.
  • Municipal Electrical Permit Pass-Through & Tax Credit Receipt: Municipal permit pass-through fee at cost, electrical inspection approval details, and Section 30C Alternative Fuel Infrastructure Tax Credit documentation.

Level 2 EV charging pricing math: NEMA 14-50 plug vs. 48A hardwired

EV charger installation pricing depends on conduit run distance, panel capacity, and charging speed:

  • Standard Installation Cost Benchmarks ($750–$1,800 total installed): Covers load calculations, breaker, 20–40 ft conduit run, and charger mounting.
  • NEMA 14-50 Outlet vs. Hardwired 48A Connection:
    • NEMA 14-50 Receptacle (40A Max Charging / 50A Breaker): Requires a heavy-duty industrial-grade NEMA 14-50 outlet (e.g. Bryant or Hubbell $65–$90 socket, NOT cheap $10 residential outlets that melt) plus a GFCI breaker per NEC 2020.
    • Hardwired 48A Continuous Charging (60A Breaker): Hardwiring directly to the EVSE charger allows maximum 48A charging (11.5 kW output), skips expensive GFCI breakers, and eliminates plug thermal failure points.
  • Linear Footage Conduit Rates ($12–$25 per foot): Price circuit runs by linear foot based on wire gauge (#6 AWG copper for 60A, #8 AWG for 40A) and conduit type (surface EMT in garages vs direct-burial PVC or core-drilling exterior brick).

Handling 100A panel constraints: Panel upgrades vs. smart load managers

When existing electrical panels lack capacity for a 50A/60A EV breaker:

  1. 200A Main Service Panel Upgrade ($1,800–$3,500): Upgrading an old 100A panel to 200A or 400A service to accommodate central AC, heat pumps, and EV chargers.
  2. Smart Load Management Switches ($650–$1,100 installed): Installing energy managers (e.g. DCC-9 or SimpleSwitch) that automatically pause EV charging whenever house electrical draw exceeds 80% panel capacity, avoiding a full panel replacement.

Utility rebates and driveway card payment collection

  • Section 30C & Local Utility Rebate Documentation: Provide an itemized PDF invoice breaking out charger equipment cost from electrical installation labor to help homeowners claim up to 30% federal tax credits and local utility rebates ($500–$1,000 credit).
  • Driveway Card Payment: Test EV charging speed using a vehicle or EVSE tester, then process payment on your phone or mobile card terminal before clearing tools.

Frequently asked questions

Should I list the conduit run length?

Yes, in feet. It's the single number that explains why this install cost more than the neighbor's, and it's the number a customer will otherwise assume you invented.

How do I invoice a customer-supplied charger?

Print the unit as a $0 line marked 'customer supplied,' with your warranty stated as labor-only. It documents that a defective unit isn't your problem, which is the entire reason to write it down.

What do I do about the permit fee?

Pass it through at cost on its own line with the jurisdiction named. Marked up or buried in labor, it's the line that gets questioned; stated at cost, it never comes up.
