What to Include on a Contractor Invoice: A Field-by-Field Checklist and Templates
Every field a contractor invoice needs, where your license number belongs, payment terms that get you paid faster, copy-paste invoice texts, and what to know before adding late fees.
A contractor invoice should include your business name, address, phone and license number; the customer's name and job address; an invoice number and date; the work done with line items for labor, parts and fees; any deposit already paid; tax; the balance due; the due date and payment terms; and how to pay, ideally with a pay link.

An invoice is the last thing a customer reads from you, and the one that decides when you get paid. A clear invoice gets paid the same day. A vague one starts a phone call, a dispute or a 60-day wait. This guide lists every field to include, what the law says about license numbers in a few states, payment terms that work, and templates you can send by text today.
Key takeaways
- Identify both sides: your business, license number and contact details; the customer and the job address.
- Describe the work in plain words with line items, so the customer can see what they're paying for.
- Show the deposit already paid and the balance due, in that order.
- Due date and terms on every invoice. “Due on receipt” is normal for residential service.
- Make paying one tap: a pay link in a text gets paid faster than a mailed bill.
- Late fees only if agreed in advance, in writing, at a reasonable rate within your state's limits.
What should a contractor invoice include?
| Field | What to put | Why it matters |
|---|---|---|
| Your business details | Legal business name, address, phone, email, website | Customers and their insurers need to know who billed them |
| License number | State contractor license or registration number | Required on contracts in many states; builds trust on every document |
| Invoice number | A unique, sequential number | Makes payments, disputes and taxes easy to track |
| Invoice date and service date | When you billed and when the work was done | Starts the clock on payment terms |
| Customer details | Name, billing address, phone or email | Who owes the money |
| Job address | Where the work was done, if different | Matters for landlords, property managers and warranty claims |
| Job or quote reference | The approved quote or work order number | Ties the invoice to what the customer agreed to |
| Description of work | Plain-language summary of the problem and the fix | “Replaced failed capacitor on outdoor unit” beats “HVAC repair” |
| Line items | Each flat-rate task, or labor hours and rate, plus parts and fees | Fewer “what is this charge?” calls |
| Discounts | Member discount, coupon, credited diagnostic fee | Shows the customer the value they got |
| Subtotal, tax, total | Tax where your state applies it | Sales tax rules for labor and parts differ by state |
| Deposit and payments received | Amount and date | Prevents the “am I paying twice?” worry |
| Balance due | The one number the customer pays | Make it the biggest number on the page |
| Due date and terms | “Due on receipt” or “Net 15” | Without a date, many customers pay when they feel like it |
| How to pay | Pay link, card, check, who to make it out to | Every extra step slows payment down |
| Warranty | Parts and labor terms on the work done | Answers the next question before it's asked |
| Thank-you line | One sentence | The last impression before they review you |
Do you need your license number on an invoice?
It depends on the state and on what the document is. A few examples from official sources:
- California: licensees must include their license number on all construction contracts, subcontracts and calls for bid, and in all forms of advertising (Business and Professions Code 7030.5). CSLB reads advertising broadly, including contract proposals, signs and vehicle lettering.
- Maryland: a home improvement contract must show the contractor's name, address, phone number and MHIC license number.
- Massachusetts: the contractor's registration number must appear on the first page of a home improvement contract.
An invoice is not always a contract, but many service invoices double as one: the customer signs it on site, or it is the only paperwork for the job. Putting your license number on every quote, invoice and receipt costs nothing and keeps you on the right side of rules like these. Check your own state board for its specific rules. This is general information, not legal advice.
What payment terms should a contractor use?
| Customer type | Common terms | Notes |
|---|---|---|
| Homeowner, service or repair | Due on receipt | Collect on site or by text before the tech leaves the driveway |
| Homeowner, install with deposit | Balance due on completion | Show the deposit already paid |
| Property manager or landlord | Net 15 or Net 30 | Agree terms in writing before the first job |
| Commercial | Net 30, sometimes with progress billing | Get a purchase order number on the invoice |
Write the terms the same way on the quote and the invoice. A customer who agreed to “due on completion” at approval doesn't argue when the invoice says the same thing. The free contractor invoice generator works out the due date from the terms you pick and prints the invoice or saves it as a PDF.

Can contractors charge late fees?
Usually yes, with care. A Nolo guide on late fees makes the main points: agree the fee in advance and in writing, show it on the invoice, keep it within your state's interest limits, and keep it reasonable, because a fee that looks like a penalty can be thrown out. It suggests that a rate of about 10% a year generally keeps you inside state limits and notes that a late fee of 1% to 1.5% is typical.
- Put it in the agreement first. A late fee that appears for the first time on an overdue invoice is hard to enforce.
- Check your state's limits. Consumer contracts often face stricter rules than business-to-business invoices.
- Use a grace period. Fees that start a day late cost goodwill for very little money.
- Ask before you charge. For a homeowner, a phone call usually gets paid faster than a fee.
This is general information, not legal advice. Ask a local attorney before adding late fees to residential work.
Mistakes that slow down payment
- Sending the invoice days later. Send it before the tech leaves, while the customer is happy with the fix.
- One vague line. “Plumbing work: $640” invites a call. Line items answer the question first.
- No deposit shown. The customer remembers paying something and stops to check.
- Only one way to pay. Offer a card link at minimum.
- No follow-up. A simple reminder schedule (day 3, the due date, a week after) clears most open invoices.
Deposits should match what's on the invoice; see how much deposit to ask for.
Where CrewRobin fits
In CrewRobin you create the invoice from the job, and it goes to the customer by text with a pay link: card through your own Stripe account, or PayPal. A deposit taken at quote approval comes off the final invoice. Once the invoice is paid in full, the customer gets one Google review request by text.
