PDF invoice or e-invoice?

Here is the key difference and what it means for you

Managing supplier invoices efficiently is one of the most important aspects of a stable cash flow. But many companies are still bogged down in manual processes that consume time, lead to errors, and make it difficult to maintain control.

Today, there are two common ways to receive invoices: PDF invoices and e-invoices. They may look similar on the surface, but they work very differently in practice.

Here’s a straightforward and easy-to-understand guide to help you choose the right format for your business.

Here's what you'll get:

What a PDF invoice actually is and why it often involves more manual work
How an e-invoice works and why it is the standard in modern digital invoice processing
The key differences between PDFs and e-invoices (automation, accuracy, compliance, Peppol, efficiency)
A clear recommendation – Which format is best suited for your business?

PDF invoice

A PDF invoice is a digital copy of a paper invoice. It is usually sent as an attachment via email.

The big downside?

The PDF format does not contain any structured data.

This means you need:

OCR transcription (which is not always accurate)
or manual entry of amounts, suppliers, dates, and account codes

PDF invoices are still common in smaller businesses, but they are far from ideal as volumes increase.

E-invoice

An e-invoice is a structured electronic invoice (e.g., PEPPOL BIS or Svefaktura) that is sent directly between business systems via a secure network such as Peppol.

It contains all data in a machine-readable format—no images, no PDFs, and no manual work.

To send e-invoices, you need a connection through a service provider (VAN/access point), but all modern accounting systems support this today.

In practice, more and more companies are opting for e-invoicing because it offers greater control, less paperwork, and faster processes.

PDF Invoice vs. E-Invoice – The Key Differences

PDF invoice:

Requires manual entry or OCR.
Risk of errors due to misinterpretation or manual entry.
Risk of delays, errors, and unnecessary duplication of work.

E-invoice:

Fully automated—data goes straight to where it's supposed to go.
100% structured data – significantly fewer errors.
Reaches the recipient directly and can be processed automatically.

How to create a PDF invoice

Export it as a PDF.

Simple but manual.

How to create an e-invoice
