How to Create a Professional PDF Invoice Online for Free

EuroTools Hub · 2026-10-09

Freelancers, small businesses and sole traders all need to send invoices. You do not need expensive accounting software to produce a clean, professional invoice: a free browser-based generator can create a PDF in a couple of minutes. This guide explains what an invoice should contain, how to fill in each field, and common mistakes to avoid.

What must an invoice contain in Europe?

Exact legal requirements depend on the country, but most European invoices include the following information:

• Invoice number: a unique number, usually in sequence (for example 2026-001, 2026-002).
• Invoice date and, where relevant, the date of supply or service.
• Seller details: name or company, address and VAT number.
• Client details: name or company and address, plus the client's VAT number for business-to-business sales.
• Description of goods or services, with quantity and unit price.
• Net amount, VAT rate, VAT amount and total.
• Payment terms and bank details, such as the IBAN and the due date.

Tips for clear, professional invoices

• Write a clear description. "Website design, 10 hours, March 2026" is better than "Services".
• State the due date and payment method so there is no confusion.
• Keep invoice numbers in order and never reuse a number.
• Use the correct currency, and show the VAT rate for each line.
• Keep copies. Tax authorities usually require you to store invoices for several years.

Reverse charge and zero-rated invoices

For some cross-border business sales inside the EU, the VAT is paid by the customer under the "reverse charge" rule. In that case you often issue the invoice with 0% VAT and add a note such as "Reverse charge". Rules are detailed and differ by country and service, so check with your tax adviser. You can set the VAT percentage to 0 and write the required note in the notes field.

Does a PDF invoice meet my country's rules?

This depends on where you and your client are. Some countries require electronic invoicing through a government platform for most businesses. Italy, for example, uses the SdI system, and other countries are introducing similar rules. A PDF invoice from a generator is a good document for many situations, but it may not replace mandatory e-invoicing. Always confirm what applies to you.

Privacy: your invoice data stays with you

Invoices contain names, addresses, VAT numbers and bank details. The EuroTools Hub generator creates the PDF inside your browser, so this information is not uploaded to a server. There is no account and no watermark.

Frequently asked questions

Is the invoice generator really free?

Yes. It is free, requires no signup and adds no watermark.

Can I use it for any currency?

Yes. You can choose the currency in the form.

Can I save my invoice data?

The tool does not store your data. Download the PDF and keep your own records.

Can I edit the PDF afterwards?

It is best to change the data in the form and create a new PDF.

Example: a simple freelancer invoice

Imagine you are a freelance designer who finished a logo project. Your invoice might contain one line: "Logo design and brand sheet", quantity 1, unit price 600 EUR, VAT 22%. The generator shows a subtotal of 600.00 EUR, VAT of 132.00 EUR and a total of 732.00 EUR. In the notes field you add "Payment within 30 days by bank transfer, IBAN ...". That is all your client needs to pay you correctly.

Common invoice mistakes to avoid

• Missing VAT number: business clients usually need it to reclaim VAT.
• Duplicate or missing invoice numbers: this can cause problems in an audit.
• Vague descriptions: they lead to questions and late payment.
• Wrong VAT rate: check the correct rate for the product or service and the country.
• No due date: clients pay faster when the deadline is clear.

After you create the invoice

Send the PDF by email with a short message, and keep a copy in a folder organised by year. If the file is large, you can reduce its size with Compress PDF. If you need to attach a contract or timesheet, combine the documents with Merge PDF. You can also check amounts in other currencies with the Currency Converter.
