Fillable PDF
Free fillable invoice template (PDF)
Last reviewed:
We built this invoice template for freelancers and small businesses who want something clean and complete without opening accounting software for a single bill. It has every block a client's accounts team expects to see: an invoice number, issue and due dates, both parties' details, an itemised table, totals and payment instructions.
You can download the fillable PDF and complete it in any PDF reader, or open it directly in our Fill PDF form tool. Filling happens in your browser, so the amounts and client names you type are not uploaded while you work.
How to fill it in
- Download the fillable PDF or open it in our Fill PDF form tool.
- Fill in the invoice number, dates and the client's PO or reference.
- Add your details and the client's billing details.
- List each item with quantity and unit price, then complete the totals.
- Add payment details, then sign the invoice with Sign PDF if your client needs a signature.
- Save it as a PDF, compress it if needed, and email it with the invoice number in the subject.
What each field is for
The invoice number is how both sides find this document later, so use a simple sequence that never repeats, such as 2026-014. Many tax authorities expect numbers to be consecutive, and gaps can raise questions. The reference field is for the client's purchase order or project code: large companies often refuse to pay an invoice without it, so ask for it before you send.
In Bill to, write the client's registered company name and billing address, not the name of the person you work with day to day. If either of you has a VAT or tax ID that has to appear on invoices, add it on the address lines.
Common mistakes we see
Most late payments come down to small, avoidable gaps on the invoice itself.
- No due date, or a vague one like "soon". Write an actual date.
- Line items that only say "Services". Describe the work and the period it covers.
- Totals that do not add up after a discount. Check subtotal, tax and discount once more.
- Missing bank details, or details for the wrong currency.
- Reusing an invoice number after editing an old file.
Sending and keeping your invoices
Send the invoice as a PDF, not as an editable document, so the numbers cannot change on the way. If the file is large because you merged in timesheets, run it through Compress PDF first. Attach anything the client asked for, such as a signed delivery note or timesheet, and put the invoice number in the email subject.
Keep a copy of every invoice you issue. Many countries require businesses to keep invoices for somewhere between five and ten years, so check the rule where you are registered. When you are signed in to pdfdots you can save finished invoices to My files, which are stored encrypted.
Frequently asked questions
Does the template calculate totals for me?
No. We kept the fields as plain text so they work in every PDF reader. Add up the amounts yourself or in a calculator and type the results into the totals block.
Can I add my logo?
The template does not have a logo field. You can add an image afterwards with our PDF editor, or simply write your business name clearly in the From block.
Do I have to charge tax?
It depends on where you are registered and how much you earn. Leave the tax field at zero if you are not registered, and check your local tax authority's rules if you are unsure.
Is my data uploaded when I fill the invoice online?
Filling the form happens in your browser. Your file only reaches our servers if you choose to save it to My files while signed in.
What should I do if a client asks for a correction?
Do not edit and resend the same number. Issue a credit note or a new invoice with a new number, and mention the original number in the reference field.
