How to Invoice Clients as a Freelancer (2026): Template, Terms and Reminders

To invoice a client as a freelancer, send a document marked “Invoice” with your details, the client’s billing contact, a unique invoice number, the issue date and a real due date, one line per deliverable with quantity and rate, the subtotal, any deposit already paid, tax if it applies, the balance due, one line of payment terms and a link to pay online. Take a deposit before you start, invoice the day you deliver, and send reminders 3 days before the due date and 1, 7 and 14 days after it.

Prices checked October 8, 2026 on each vendor’s own pricing page, in US dollars and billed monthly unless noted. Tax and invoice rules differ by country and state: this guide is general information, not tax or legal advice.

What to include on a freelance invoice

Every freelance invoice needs these ten things. Miss one and the invoice waits in someone’s inbox while they ask you about it.

• The word “Invoice” at the top, so nobody mistakes it for a quote.
• Your details: your name or business name, email and address.
• The client’s billing details: the company, the person, and the email of whoever actually pays. At larger companies that is often accounts payable, not your day-to-day contact.
• A unique invoice number from a simple sequence, such as 26-089. Never reuse one.
• A project reference such as “Brand identity”, plus the client’s PO number if they gave you one.
• Two dates: the issue date and the due date, written as a date. “Due November 7” is clearer than “Net 14”.
• Line items: one per deliverable, each with a quantity and a rate.
• Totals: subtotal, minus any deposit already paid, tax if it applies, and the balance due.
• One line of payment terms, such as “Payment due within 14 days”.
• How to pay: a pay-online link, plus one backup such as a bank transfer.

Legal requirements depend on where you work. In the UK, for example, GOV.UK’s invoice guidance says an invoice must include a unique identification number, your company name, address and contact information, the customer’s company name and address, a clear description of what you’re charging for, the supply date, the invoice date, the amounts charged, VAT if applicable and the total owed. Sole traders using a business name also need their own name and an address where legal documents can be delivered. Other countries and US states have their own rules, so check yours or ask an accountant.

Freelance invoice template

The example amounts are illustrative. Replace them with your own rates.

Invoice line items, totals and tax

Write line items the way the client remembers the work. “Logo, three concepts” gets approved faster than “design work”, because the person approving it can match it to what they received.

• Hourly work: show the hours and the rate, such as 3 hours at $95.
• Fixed-fee work: one line per deliverable or milestone, matching the wording in your proposal.
• Discounts: show the full price first, then the discount on its own line, so the client sees what they saved.
• Costs you pass on: stock photos, fonts, printing or travel each get their own line.
• Deposits: subtract the deposit already paid before the balance due. It heads off the classic question, “didn’t we already pay you?”
• Tax: add sales tax or VAT only where it applies. If you aren’t sure, ask an accountant before your first invoice.

Keep each line short: the detailed scope lives in your proposal.

Freelance payment terms that get you paid

Payment terms are the one line that tells the client when the money is due. Agree them in the proposal before any work starts, then repeat them on every invoice so clients learn your rhythm.

Short terms help: on receipt, or 7 to 14 days. If a large client insists on 30 days, agree it before you start and price the wait in. In the UK, GOV.UK explains that when no payment date is agreed between businesses, a payment counts as late 30 days after the customer gets the invoice or you deliver the work, whichever is later.

Two optional extras. An early-payment discount can help, though a deposit usually does more. A late fee only works if the client agreed to it first, in the proposal and on the invoice, and your local rules allow it.

When to invoice a client

Match the billing split to the shape of the project.

• Small project: half before you start, half on delivery. The deposit invoice has one line, such as “Brand identity, 50% deposit”, and is due before the start date, so the work starts when it’s paid.
• Bigger project: a deposit, a milestone the client can see (such as design approved) and the final delivery. Money comes in while you work, not all at the end.
• Long project with no natural milestones: invoice monthly for the work done so far.
• Hourly or ongoing work: invoice on a fixed day, such as every other Friday or the last day of the month.

Whatever the shape, invoice the day you deliver. A late invoice tells the client that paying late is fine.

Before the project starts, ask the client five questions:

1. Who approves invoices, and which email should they go to?
2. Do you need a PO number on the invoice?
3. When do you run payments? Many companies pay in batches once or twice a month, so send before the run.
4. Do you need a tax form from me first? In the US, a client may ask for Form W-9, which the IRS describes as the form you use to give your taxpayer identification number to someone who has to report what they paid you.
5. For clients abroad: which currency? Agree it in the proposal and show it on every amount.

How to send an invoice to a client

Send a link the client can pay from right away, and attach a PDF only if their accounts team wants one. Send it from the address the client knows and copy your main contact.

Subject: Invoice 26-089, Brand identity, due November 7

Hi Elena,

Here’s invoice 26-089 for the brand identity work: $1,545 after the deposit, due November 7. You can pay online here: [link].

Thanks again for a great project. Let me know if your team needs anything else to process it.

[Your name]

Two lines of content is plenty. Put the number, the amount, the due date and the link above anything else, so the person who pays can act without opening an attachment.

Payment reminder email templates

Plan the reminders the day you send the invoice, then put them on your calendar or let software send them. Every reminder names the invoice number, the amount and the due date, uses the same pay link, and stays polite and firm. Stop the moment the client pays.

3 days before:

Hi Elena, a quick heads-up: invoice 26-089 for $1,545 is due Friday, November 7. Here’s the link if it helps: [link]. Thanks!

1 day late:

Hi Elena, invoice 26-089 for $1,545 was due yesterday. Here’s the link again: [link]. Could you let me know when to expect payment?

7 days late:

Hi Elena, invoice 26-089 for $1,545 is now a week overdue. Can you confirm a payment date by Friday? If it’s stuck in approvals, tell me who to contact and I’ll send it straight to them. [link]

14 days late (final notice):

Hi Elena, invoice 26-089 for $1,545 is now two weeks overdue. As agreed in our terms, work on the next phase is paused until it’s settled. Please pay here: [link], or reply with a date today so we can plan around it.

By text, keep it to one line: “Hi Elena, quick nudge on invoice 26-089, $1,545. Here’s the link: [link].”

What to do when a client doesn’t pay

A late invoice is usually forgotten or stuck in an approval queue, not refused. Check it arrived (invoices land in spam), then call and ask one question: when can we expect payment? Confirm the date by email the same day.

Still unpaid after the final notice? Pause new work if your terms said you would, offer a written payment plan for what’s left, and keep every message calm and on record. For larger amounts, a collections agency or small claims court are options; rules differ by place, so check yours first. Next time, take a bigger deposit: it caps what a non-payer can cost you.

How to invoice clients in Workspace369

Our #1 pick is Workspace369, and we make it. It suits freelancers who want the proposal, the invoice, the payment and the reminders in one place instead of a spreadsheet and PDFs. Workspace369 pricing

• Invoices and pay links on every plan. Each invoice has a public link the client can view and pay online by card without creating an account, and it is marked paid in your workspace. Clients can also pay from their client portal after verifying their email.
• Proposal to invoice in one step. On every plan, an accepted proposal converts into the invoice, so the line items match what the client agreed. Deposits are on every plan, and deposit on acceptance, where the client accepts the proposal and pays the deposit in the same step, starts on Specialist ($149 a month).
• Hours to invoice. On Voyager ($74 a month, 2 seats), start a timer, stop it, pick the unbilled time and it lands on the invoice at your rate.
• Reminders that stop when the client pays. Email workflows run on every plan, up to 3 active on Cadet ($29 a month, 1 seat). The “Escalating unpaid invoice reminders” template sends a reminder the day after the due date, an escalation at 7 days and a 30-day final notice, and it stops if the invoice is paid. For the note before the due date, the “Invoice due soon” trigger starts a workflow 1 to 30 days ahead, 3 by default. Text steps start on Voyager.

Every plan has a 14-day free trial. Paying yearly saves 20%, so Cadet works out to $23.25 a month.

Freelance invoicing tools that send reminders

A spreadsheet and PDFs work for a few clients. Past that, reminders and who-paid-what start to slip.

Frequently asked questions

How do I invoice a client for freelance work?

Create an invoice with your details, the client’s billing contact, a unique number, the issue and due dates, itemized lines, totals and one line of payment terms, then email it with a pay-online link the day you deliver. Save the layout as a template so every invoice is consistent.

What should be included on a freelance invoice?

The word “Invoice”, your details, the client’s billing details, a unique invoice number, the issue date and due date, line items with quantity and rate, the subtotal, any deposit paid, tax if it applies, the balance due, payment terms and how to pay. Check your country’s rules: the UK’s GOV.UK guidance also requires the supply date.

What payment terms should a freelancer use?

Short terms get paid sooner: due on receipt, or 7 to 14 days. Agree them in the proposal before you start, and take a deposit on new projects. If a large client needs 30 days, agree it up front.

When should I send an invoice to a client?

Send the deposit invoice before the work starts and the final invoice the day you deliver. For hourly or ongoing work, invoice on a fixed day, such as every other Friday or month-end.

How do I invoice for a deposit?

Send a separate invoice with one line, such as “Brand identity, 50% deposit”, due before the start date. On the final invoice, list the whole job and subtract the deposit already paid.
