Do I need a business license number on my invoice?

In most states, yes. Your electrical license number should be on every invoice, quote, and contract. It's required by law in many jurisdictions and it makes you look professional.

Should I charge tax on electrical work?

It depends on your state. In many states, labor is not taxable but materials are. In some states, everything is taxable. Check with your accountant or your state's department of revenue.

What's the best invoice numbering system?

Keep it simple. Sequential numbers (INV-001, INV-002) or date-based (2026-0301-01). The important thing is that every invoice has a unique number for your records.

Can I charge late fees?

In most states, yes — as long as it's disclosed on the invoice. A common approach is 1.5% per month on overdue balances. Check your state's usury laws for maximum allowed rates.

What Every Electrical Invoice Needs

A professional invoice isn't just a number on a piece of paper. It's a legal document that protects you and makes it easy for the customer to pay. Here's what to include:

Your business name, address, phone, and license number
Customer name and address
Invoice number (sequential — INV-001, INV-002, etc.)
Date of service and invoice date
Detailed line items — don't just write "electrical work $500"
Labor hours and rate (e.g., 3 hours × $85/hr = $255)
Materials with itemized costs
Subtotal, tax (if applicable), and total
Payment terms (Net 15, Net 30, or Due on Receipt)
Payment methods accepted (card, check, ACH)

When to Send the Invoice

Short answer: immediately after the job. Not when you get home. Not on Friday afternoon. Right there on the job site.

Every day between finishing a job and sending the invoice is a day you're not getting paid. The customer's memory of the work is freshest right after you finish. Their motivation to pay is highest. Don't let that window close.

How to Describe Electrical Work on an Invoice

Vague invoices lead to disputes. Detailed invoices get paid. Here are examples:

❌ Bad

Electrical work — $500

✓ Good

Replace 200A main breaker panel — labor: 4 hrs × $85/hr = $340

Square D 200A panel — $185

Breakers (8) — $96

Wire, connectors, misc materials — $45

Total: $666

Payment Terms: What to Set

For residential work: Due on Receipt or Net 7. Residential customers who don't pay within a week usually don't pay within a month either.

For commercial/GC work: Net 30 is standard. Some GCs push for Net 60. Push back — Net 30 is fair.

Pro tip: offering online payment (credit card or ACH) dramatically reduces time to payment. When the customer can pay from their phone in 30 seconds, most of them will.

Following Up on Unpaid Invoices

Don't be awkward about it. This is business. Here's a simple timeline:

Day 1: Send the invoice
Day 7: First reminder — "Hey, just wanted to make sure you received the invoice"
Day 14: Second reminder — "This invoice is now past due. Please remit payment."
Day 30: Phone call. Direct, professional, firm.
Day 45+: Consider a collection process or small claims court for large amounts

Or — use invoicing software that sends automatic reminders for you. That way you're not the bad guy, the system is.
