How to Invoice as a Contractor
The short answer: To invoice as a contractor, send a clear document that lists your business and license info, the client, an invoice number and dates, an itemized breakdown of labor and materials, any tax, any deposit you already collected, and the balance due with payment terms. Send it promptly, and most contractors get paid by check, card, or bank transfer.
What every contractor invoice needs
An invoice is a payment request your client can act on without calling you back. If they have to ask "what is this for?" or "how do I pay you?", the invoice is missing something. Here is what every contractor invoice should carry.
| Section | What goes here |
|---|---|
| Your business info | Business name, address, phone, email, and license number if your trade or state uses one |
| Client info | The client's name, the job address, and a billing contact |
| Invoice number and dates | A unique invoice number, the issue date, and the due date |
| Line items | Each labor and material item, with quantity, rate, and line total |
| Subtotal and tax | The sum of the line items, then sales tax if it applies in your state |
| Deposits and prior payments | Any deposit or progress payment already collected, subtracted from the total |
| Balance due | The final amount the client owes, in bold and easy to find |
| Payment terms | When it is due and how to pay (check, card, bank transfer) |
The invoice number matters more than it looks. It is how you and your client track which bill is which, especially on a job with several draws. Number them in a simple sequence and never reuse one.
How to write an invoice, step by step
The flow is short. Follow it in order and you will not forget a piece.
- Start with the header. Put your business name, contact info, and license number up top. This is your professional identity on the document.
- Add the client and the job. Name the client and the job address so there is no question which property the bill covers.
- Assign an invoice number and dates. Give it the next number in your sequence, today's date, and a due date based on your terms.
- Itemize labor and materials. List each piece of work and each material with a quantity, a rate, and a line total. Specific beats vague: "Tile labor, 60 sq ft at $12" beats "tile work."
- Total it up. Add the line items into a subtotal, apply sales tax if your state charges it, then subtract any deposit or prior payment.
- State the balance due and terms. Show the final number clearly, say when it is due, and list how to pay.
That is the whole document. The only step people skip is itemizing, and it is the one that prevents a dispute, because the client can see exactly what they are paying for.
A contractor invoice example
Here is a worked example so you can see the math. Say you finished a bathroom remodel, the client paid a $1,500 deposit up front, and your state charges sales tax on materials. The invoice line items might look like this.
| Description | Qty | Rate | Amount |
|---|---|---|---|
| Demolition and haul-away (labor) | 8 hrs | $65 | $520.00 |
| Tile setting (labor) | 16 hrs | $70 | $1,120.00 |
| Plumbing fixture install (labor) | 6 hrs | $85 | $510.00 |
| Porcelain floor tile | 60 sq ft | $9 | $540.00 |
| Vanity and sink | 1 | $850 | $850.00 |
| Shower fixture set | 1 | $360 | $360.00 |
| Subtotal | $3,900.00 | ||
| Sales tax (materials, 7%) | $122.50 | ||
| Deposit received | -$1,500.00 | ||
| Balance due | $2,522.50 |
Notice the order: subtotal first, then tax, then the deposit comes off, then the balance due. The deposit is subtracted after tax because it is money already applied to the job, not a discount on the work. Sales tax here is charged on materials only, but what gets taxed depends on your state, so confirm yours. The balance due is the number the client pays, and it should be the easiest thing to find on the page.
How do contractors get paid
Most contractors get paid one of a few ways, and the invoice should tell the client which you accept.
- Check. Still common in construction, and there is no processing fee, but it takes days to clear.
- Bank transfer (ACH). Fast, cheap, and clean for larger balances. You share your account details or send a payment link.
- Card. The easiest for clients, and offering it tends to get you paid faster. You usually pay a processing fee of a few percent, which you can absorb or build into your pricing.
On bigger jobs you often bill in stages instead of one final invoice. That is progress billing, where each draw covers the work done so far. The deposit you collected up front is the first piece of that same pattern.
Tips that get you paid faster
The invoice is only half the job. How you send it decides how fast the money lands.
- Invoice promptly. Send it the day the work wraps, not next month. The longer you wait, the colder the bill gets.
- Make the terms obvious. State the due date and the accepted payment methods in plain words. "Due within 15 days. Pay by check or card" beats burying it.
- Accept cards. The small fee is usually worth getting paid in days instead of weeks.
- Keep your numbers clean. A clear subtotal, tax line, and balance due means fewer questions and faster approval.
Two payment topics deserve their own read. If a client holds back a percentage of each payment until the job is done, that is retainage, and we cover it in what is retainage. If you are setting a due window like Net 30, see Net 30 payment terms for what it means and when to use it.
You can build all of this by hand, but a tool that does the math is faster and harder to get wrong.

- Every contractor invoice needs your business and license info, the client, an invoice number and dates, itemized labor and materials, tax, deposits, the balance due, and payment terms.
- Total it in order: subtotal, then tax, then subtract any deposit, then show the balance due.
- Itemizing labor and materials is the step that prevents disputes, because the client sees what they pay for.
- Invoice promptly, state clear terms, and accept cards to get paid faster.
An invoice is your own professional document, sent to a client. This is general information, not legal or tax advice, and sales tax rules depend on your state.
