How do I write a professional electrical bid proposal?
Updated · Amperio.ai team
Short answer
Amperio.ai generates a professional electrical proposal directly from your estimate. A strong proposal includes 10 elements: company info and license number, client and project, scope of work (per NEC and local code), line items or base bid, alternates, exclusions, schedule, payment terms (for example deposit plus progress billing), warranty and validity (typically 15–30 days because of copper price swings).
| Section | What to include |
|---|---|
| Header | Logo, company, license #, contact, date, proposal # |
| Client & project | Name, address, job type |
| Scope | What is installed, code basis (NEC + local amendments) |
| Pricing | Base bid, line items or allowances, alternates |
| Exclusions | Utility fees, trenching, patch & paint, permits if not included |
| Terms | Schedule, payment terms, warranty, validity |
Mistakes that lose jobs
- A single lump sum with no scope detail.
- Missing exclusions, which leads to unpaid change work.
- No validity date while material prices move.
- An informal text-message quote.
