An independent contractor invoice is the bill a self-employed person sends a client after doing the work: who did what, when, at what rate, and how much is due by when. This free template works for hourly work or flat fees, in Word or PDF, and it includes an optional line for the client to approve the hours before payment. It’s a sample invoice for independent contractors who bill clients directly, not a payroll form.

When is an invoice the right document, and when isn’t it?

An invoice asks for payment for work that’s already been agreed. It shouldn’t be where the terms get decided. If you and the client haven’t agreed the scope and rate in writing, do that first with an independent contractor agreement. If the client wants a price before saying yes, that’s a quote, not an invoice. For monthly ongoing work, a retainer agreement sets the fee, and the invoice just follows it each month.

The order that saves the most grief: quote, then contract, then invoices. Each invoice then points back to the contract, and there’s nothing to argue about.

What goes on an independent contractor invoice?

Here’s what each part of our invoice template is for, using a hypothetical. Say Marcus is a freelance video editor who bills a small agency by the hour.

Your details and the client’s. Marcus’s business name (or his own name), address, email and phone, and the client’s legal business name, billing address and the contact who approves invoices. Get the client’s name exactly right; an invoice made out to the wrong entity can bounce around an accounts team for weeks.

Invoice number, dates and reference. A unique number (Marcus uses 2026-014 style numbering), the invoice date, the due date, and the client’s purchase order number or the contract date if there is one.

Line items. One row per piece of work, with the date or period, a short description, hours or quantity, rate and amount. “Editing, episode 3, rough cut, 6.5 hours at $75” is clearer than “video work, $487.50.” For hourly billing, this is where a client decides whether to trust your hours, so be specific.

Expenses. Reimbursable costs the contract allows, listed separately from fees, with receipts attached.

Totals. Subtotal, any discount, any sales tax you’re required to charge (this depends on your state and the service), amount already paid, and balance due.

Payment terms. When it’s due (say, 15 or 30 days), how to pay, and any late fee the contract allows. Don’t add a late fee on the invoice that isn’t in your agreement.

Client approval (optional). A signature line where the client confirms the hours or deliverables. Useful for hourly work and for clients whose finance team needs a manager’s sign-off before paying.

What tax paperwork goes with contractor invoices?

A few things from the IRS are worth knowing, and they’re about the relationship, not the invoice itself.

Form W-9. The IRS says that once a business decides it’s paying an independent contractor, the first step is having the contractor complete Form W-9, which gives the payer the contractor’s correct name and taxpayer identification number. Expect a new client to ask for one before your first payment. The IRS also says payers should keep these records for four years.

Form 1099-NEC. The client uses Form 1099-NEC to report nonemployee compensation. Businesses file it for payments that total or exceed the reportable payment threshold during the tax year. The threshold is set out in the IRS instructions for Forms 1099-MISC and 1099-NEC, so check the current year’s version rather than a number from an old blog post. Keep your own invoices numbered and filed; they’re how you’ll reconcile what the client reports.

Invoicing doesn’t make you a contractor. The IRS’s general rule is that someone is an independent contractor if the client has the right to control or direct only the result of the work, not how it’s done, and it says the answer depends on the facts in each case. Sending invoices instead of timesheets doesn’t change that.

How do you fill it in and send it?

Copy your business details and the client’s billing details into the header once, then save that as your own starting file.
Number each invoice in sequence. Never reuse a number.
Add one line per task or period, with hours and rate. Attach receipts for expenses.
Check the total and due date against your contract.
Send it to the billing contact the client named, as a PDF. If the client wants to approve hours, send it for their signature on the approval line.
Log it, and follow up politely the day after the due date if it’s unpaid.

If you use the client approval line, any e-signature tool will do; the approval is just a confirmation, and an electronic signature works for it. Our guide to signing a PDF online covers the options. Download the template, fill in the blanks, and send it however suits you. (We’re building SignWren, an e-signature tool; join the waitlist if you’re curious.)

Quick answers

What should an independent contractor invoice include?

Your name and contact details, the client's details, an invoice number and date, a description of the work with hours or quantities and rates, any expenses, the total due, the due date and how to pay. Referencing your contract or purchase order helps the client's accounts team match it.

Do I need to send a W-9 with my invoice?

Not with every invoice, but expect to fill one in. The IRS says the first step for a business paying an independent contractor is to have the contractor complete Form W-9, which gives the payer your correct name and taxpayer identification number.

Will my client send me a 1099?

If their payments to you during the tax year reach the IRS reporting threshold, the client generally files Form 1099-NEC to report nonemployee compensation. The IRS instructions for Forms 1099-MISC and 1099-NEC list the current threshold and exceptions.

Does an invoice need a signature?

Usually not. An invoice is a request for payment, not a contract. The optional client approval line is useful when a client's accounts team wants a manager's sign-off, or when you bill hours and want the client to confirm them.
