How to do it — step by step
Add your business details
Type your business name, address, email and phone number. Add your logo if you have one — it makes the invoice look professional and helps clients remember you. Your details go at the top of the invoice, where the client looks first.
Add your client and an invoice number
Add your client's name, address and email. Then give the invoice a unique number, such as INV-001, and set the issue date and the due date. Never reuse a number: every invoice you send should have its own number, in order, so you can find it again later.
List every item clearly
Add one line for each piece of work: what you did, how many hours or units, and your rate. The line total is quantity times rate, and the subtotal is the sum of all the lines. Clear lines mean fewer questions from the client — and faster payment.
Set tax, discount and payment terms
If you charge tax, enter the tax percentage; if you agreed a discount, enter the discount percentage. Both are calculated for you automatically. Then write your payment terms in plain words, for example: “Payment due within 14 days by bank transfer.”
Preview, download and send
Check the live preview — it shows exactly what your client will see. Press “Download PDF”, choose “Save as PDF” in your browser's print dialog, and attach the PDF to an email to your client. The generator never sends emails for you, so your invoice stays private until you send it.
About how to make an invoice as a freelancer
A freelancer invoice has one job: get you paid, on time, without questions. To do that it needs a few things every time. Your business name and contact details at the top, so the client knows who is asking to be paid. Your client's name and address, so the invoice reaches the right person and the right accounts department. A unique invoice number and an issue date, so both of you can refer to it later. An itemised list of the work — what you did, how much of it, and at what rate — so the client can see exactly what they are paying for. And a total that adds up, with the due date and payment terms where the client cannot miss them. Leave any of these out and you invite delays: a client who cannot work out what the invoice is for, or when it is due, will put it at the bottom of the pile.
Invoice numbers matter more than most new freelancers think. A simple sequence — INV-001, INV-002, INV-003 — does three jobs at once. It lets you find any invoice in seconds when a client asks about it. It shows the client that you run a proper business, not a one-off favour. And it keeps your records straight for tax time: when every invoice has its own number, in order, nothing gets paid twice or forgotten. The Invoice Generator helps here — press “New invoice number” and the number goes up by one each time. If you invoice more than one client, keep one sequence for everyone rather than a separate sequence per client, so the numbers never collide.
The due date is where most late payments are born. Set it on the invoice, in words your client cannot miss: “Payment due within 14 days” is clearer than a bare date, and “Payment due within 30 days by bank transfer” tells the client how to pay as well as when. Shorter terms get paid faster — 14 days is normal for freelancers, 30 days for larger companies — but agree the term with the client before you start the work, not after you send the invoice. Send the invoice the day the work is finished, or on the milestone date you agreed, while the work is still fresh in the client's mind. If the due date passes, follow up politely with a short reminder and a copy of the invoice attached: most late payments are forgotten payments, not refused ones.
Keep a copy of every invoice you send. Download the PDF, save it with a clear name — for example INV-001-ClientName.pdf — and keep a simple list of invoice numbers, clients, amounts and whether each one is paid. That list is your income record: it tells you what you earned, who still owes you money, and what to declare at tax time. Because Invoice Generator never uploads your data, the copies on your own computer are the only record — so save them somewhere safe, and back them up. A freelancer who can show a clean run of numbered invoices looks professional to clients, to accountants, and to the tax office.

Frequently asked questions
What should a freelancer invoice include?
Your business name and contact details, your client's name and address, a unique invoice number, the issue date and the due date, an itemised list of the work with quantities and rates, the subtotal, any tax or discount, the grand total, and your payment terms. Every one of these is a field in the free Invoice Generator.
How do I number my invoices?
Use one simple sequence for all clients — INV-001, INV-002, INV-003 — and never reuse a number. The generator's “New invoice number” button raises the number by one each time, so your sequence stays in order.
When should I send an invoice?
Send it the day the work is finished, or on the milestone date you agreed with the client. Sending promptly, while the work is fresh in the client's mind, is the single best way to get paid on time.
How do I get paid faster as a freelancer?
Send the invoice promptly, put a clear due date and payment method on it, list the work item by item so there is nothing to query, and follow up politely the day after the due date passes with a copy of the invoice attached.
Do I need to charge tax on a freelance invoice?
That depends on your country and whether you are registered for tax. The generator has a tax field that calculates it for you, but the percentage you charge is your decision — check your local tax rules, because the tool is not tax advice.
Is the invoice generator really free?
Yes. The generator and all three templates are 100% free, with no account, no sign-up and no watermark on your invoice. Your data stays in your browser and is never uploaded.
