How to invoice as a freelancer: rates, terms and a worked example

How to invoice as a freelancer comes down to six steps: agree your rate and terms in writing, take a deposit, track your time, send an invoice with a clear due date as soon as work is accepted, make paying easy, and keep a share of every payment for taxes. The rest of this guide shows each step.

Step 1: set a rate that covers more than your salary

Freelancers often copy a salary into an hourly rate and end up underpaid. Employees get paid for every working hour. You do not. You also pay your own software, equipment, insurance, taxes and time off, and a big part of your week goes to sales, admin and invoicing that no client pays for.

A simple method:

1. Pick the income you want to take home in a year.
2. Add your yearly business costs: software, equipment, insurance, accounting, workspace.
3. Estimate your billable hours. Be honest. If you work 46 weeks a year and bill 25 hours in a typical week, that is 1,150 hours.
4. Divide the required revenue by the billable hours.
5. Add room for tax and a buffer so you are not guessing later.

Step 2: agree terms in writing before work starts

A one-page agreement or an accepted quote prevents most billing disagreements. It should say:

• Scope. What you will deliver and what is not included.
• Price and basis. Hourly rate, fixed fee, or retainer.
• Deposit and milestones. When money is due.
• Payment terms. The number of days, the due date rule and accepted payment methods. See invoice payment terms.
• Revisions and extra work. How many rounds are included and what extra work costs.
• Expenses. Which costs you pass on and whether you add markup.
• Late payments. Any late fee, worded so it is allowed where you live. See how to charge late fees.
• Ownership. When the client gets the rights to the work, which is often after final payment.
• Cancellation. What happens to the deposit and finished work if the client stops the project.

This is general information, not legal advice. For a large contract, have a lawyer read it.

Step 3: take a deposit

A deposit confirms the client is serious and funds the early part of the work. For projects, 25 to 50 percent is common. For small jobs under a few hundred dollars, many freelancers bill in full on delivery or ask for payment up front. Issue a deposit invoice that says what it covers, for example “Deposit, 40 percent of fixed fee.” On the final invoice, show the deposit as a deduction so the client sees exactly what remains. How to get paid faster covers deposits and milestones in more depth.

Step 4: track time and costs as you go

Do not rebuild a month from memory. Record:

• Date, task and hours for each piece of work, even when you quote a fixed fee, so you learn how long jobs really take.
• Receipts for any cost you will pass on to the client.
• Client approvals by email, in case the scope changes.

A basic spreadsheet is enough. The invoice itself will take two minutes when the notes are clean.

Step 5: write and send the invoice

An invoice for a freelancer needs the same core fields as any other. The long version is in how to write an invoice. The short version:

• Your name or business name and contact details, plus any tax ID your country requires.
• The client’s legal name and billing address, and their PO number if they use one.
• A unique invoice number (see invoice numbering) and the invoice date.
• A real due date, not only “Net 14.”
• Line items with description, quantity, rate and total.
• Subtotal, deductions such as the deposit, any tax, and the total due.
• How to pay.
• Your late fee policy, if your agreement includes one.

Send it the same day the work is accepted, to the person who approves payments as well as your day-to-day contact. Say in the email what the invoice is for, the amount, the due date and the payment method.

A worked example

Sam is a freelance copywriter. A software company hires them to rewrite a product website. They agree 60.00 USD an hour, an estimate of 38 hours, a 500.00 USD deposit and Net 14 terms. Sam also buys a 45.00 USD stock photo license for the client, which the agreement says Sam may pass on at cost.

Here is how it looks as a preview of the billable lines:

The preview shows the work and the pass-through cost. The 500.00 deposit already paid is subtracted to reach the 1,825.00 balance. If Sam had gone over the 38-hour estimate by a lot, the agreement’s extra-work clause would apply and Sam would tell the client before billing the difference.

Step 6: plan for taxes

Taxes catch many new freelancers off guard because nobody withholds them from your income. This section covers the United States. Rules elsewhere differ, so ask a local accountant.

• You usually pay estimated tax during the year. The IRS says self-employed people are generally required to file an annual income tax return and pay estimated taxes quarterly, using Form 1040-ES to figure them.
• Self-employment tax applies. The IRS describes it as a Social Security and Medicare tax for people who work for themselves. The rate is 15.3 percent, made up of 12.4 percent for Social Security and 2.9 percent for Medicare. You owe it if your net earnings from self-employment were 400 dollars or more.
• The Social Security part has a yearly earnings cap, which the IRS updates, so check the current figure.
• Keep records. The IRS lists invoices among the documents that support your books and return. Keep copies of every invoice, receipt and payment record.

A practical habit: when a payment arrives, move a fixed share into a separate savings account right away. Ask an accountant to pick the percentage, since it depends on your income, state and deductions.

Step 7: follow up without drama

Most late clients are busy, not hostile. Schedule your follow-ups when you send the invoice:

• 3 days before the due date: short reminder with the link or bank details.
• On the due date: “Due today.”
• 7 days late: ask if anything is blocking payment.
• 14 days late: restate the amount, the due date and any late fee in your terms.

The how to ask for payment guide has scripts. If a client keeps paying late, change their terms: a larger deposit, shorter due dates or smaller milestones.

Mistakes freelancers make

• Starting work without a written agreement. Even an email that says “I confirm the scope, price and terms” helps.
• Underpricing. A rate that ignores unpaid time and costs leaves you earning less than you think.
• Invoicing at the end of the month. The client forgets the details and the payment clock starts late.
• Mixing deposits and final invoices. Always show the deposit as a labeled deduction.
• Vague line items. “Consulting” invites questions. “Website copy, 38 hours at 60.00” does not.
• Not tracking expenses. Pass-through costs you forget to bill are lost money.
• Ignoring taxes until April. Set aside money from each payment.
• Chasing on social media or in anger. Keep follow-ups short, factual and written.

Checklist

• You know your hourly rate and what it covers.
• A signed or accepted quote states scope, price, terms, revisions and ownership.
• A deposit invoice has been sent and paid before work starts.
• You track time and expenses as you work.
• The invoice has a unique number, a real due date, clear lines and payment instructions.
• You send it the same day work is accepted.
• You have a reminder schedule.
• A share of each payment goes to a tax account.
• You keep copies of invoices and receipts in a folder you can find.

US figures come from the IRS pages on self-employment tax (15.3 percent, split 12.4 and 2.9, and the 400 dollar net earnings threshold), the self-employed tax center (annual return and quarterly estimated tax, Form 1040-ES) and what kind of records to keep. The rate example is arithmetic with assumed numbers, not a recommendation. Tax rules outside the US differ, so check with your local tax authority or an accountant.
