Is PDF Invoice an Electronic invoice

While PDFs have been widely used for invoices, their limitations in automation and compliance are becoming increasingly apparent. E-invoicing, however, offers a future-proof solution by eliminating manual data entry and streamlining financial processes. This guide explores how to make the transition from PDF to e-invoices smoothly and efficiently.

Isn’t a PDF also an e-invoice? Although you may receive it digitally, it is not. A PDF invoice still needs to be processed in the same way as a traditional paper invoice, which involves manually creating and sending it, having a human view it, manually extracting and verifying the data, and then making the payment. An e-invoice, on the other hand, does not look like a traditional invoice at all; it resembles a piece of code. This code contains all the same information that appears on the PDF, but in a format that can only be understood by a computer. As a result, the entire process is automated, requiring little to no human intervention.

    A Quick Explanation

    Invoices are most of the time directly exchanged between two parties and in this so-called two-corner model, two parties make arrangements on the invoice format they use and about the technical connection, meaning some still use paper invoices, most PDF invoices and some already transitioned to e-invoices.

    Many companies often think that e-invoicing is sending invoices by e-mail. But e-invoicing is more than just sending the invoice digitally. It is also the electronic booking, payment and collection of the money and most importantly, it is not a human readable invoices. It is made for the machines, a piece of code, allowing the process to be automated in the software, without any human interaction needed. An example, let’s say you recieve a PDF invoice. You still have to manually put data into a systems or sometimes correct it.

    Therefore electronic invoicing leads to a major save of costs. As much for the sender as the receiver. Since e-invoicing is digitalising invoicing for the sender as well as the receiver, a PDF-invoice is not seen as electronic invoicing.

     

    Key Differences for Businesses

    E-invoice PDF Invoice
    Format Structured, machine-readable (e.g., XML, JSON) Unstructured, human-readable
    Processing Automated (no manual input needed) Manual or OCR processing required
    Compliance Often meets tax authority standards May require additional steps for compliance
    Speed Faster exchange and processing Slower due to manual intervention
    Integration Works directly with ERP/accounting systems Requires data extraction or manual integration
    Audit Trail Supports real-time tracking and verification Limited or manual tracking capabilities

     

     

    What is an PDF invoice?

    Even though PDF invoices are created, sent, and received electronically, their digital format doesn’t support automated data processing. For the information to be processed, it has to be entered manually into the accounting system. Moreover, a PDF invoice does not comply with the standards and mandates of e-invoicing.

    Imagine it like this; a PDF invoice present information in a human-readable format, like paper invoices, in electronic form. For fully automated electronic processing, the invoice information contained in a PDF must still be entered into the accounting software, either by hand or using additional systems (such as OCR).

    Advantages Challenges
    Ease of Use Simple to create and share. Requires manual data entry, increasing the risk of errors and slowing processes.
    Cost Cost-effective; no advanced technology needed. Often does not meet legal standards for tax reporting.
    Scalability Universal format; works on any device. Not suitable for businesses handling large volumes of invoices.

     

    How To Create A PDF Invoice

    The easiest way to make an invoice is to go online and find an invoice template you like, then simply use it for all invoices going forward. Many invoicing software programs, like Apollo; offer a professional-looking invoice template that allows you to add new information every time you issue a new invoice. All you have to do is choose a client and product or service from the list (You created once and forever) and the invoice is issued, from the app. However if you don’t use the invoicing software the usual process would look something like:

  • Collecting Invoice Data Client information, your business information, invoice details, itemized list of foods/services, taxes, total amount, payment details.
  • Choosing a Template
  • Inputting Data Manually fill in the data if you're using static templates, or automate it using invoicing software or APIs connected to your business systems.
  • Converting to PDF
  • Validation Double-check all details for accuracy and ensure compliance with local invoicing regulations.

    What is an E-invoice?

    An e-invoice is a digital document created, transmitted, and received in a structured electronic format; being a piece of code; that enables it to be processed automatically by the recipient’s accounting or ERP system. Common format is XML and is usually sent via secure networks like PEPPOL or other government-approved platforms.

    It sounds like a lot more work than a normal PDF invoice, but stand with me. The key difference between an e-invoice and a scanned paper or PDF invoice is that an e-invoice is created in a specific structured format, being a piece of code. Therefore it is not readable to a human eye and you’d have to transform it to pdf ot read it. That allows it to be created, sent and received automatically, without human interaction from one software directly into another with no manual mistakes in the process.

     

     

    Why You Should be Converting PDF Invoices to E-invoices

    Electronic invoicing is taking over the world. According to a study commissioned by Billentis, 55 billion e-invoices will be exchanged between trading partners worldwide by 2025, marking a 20% annual growth rate. But why is that? Because e-invoicing adds value to your business while freeing up your team to work on other growth areas. Here is some benefit of leaving PDF files behind and changing to e-invoicing:

  • Compliance and tax standards In many countries, electronic invoicing is becoming mandatory. Governments often require businesses to submit invoices in structured XML formats like and sent them through networks like PEPPOL to ensure transparency and accuracy. Not only e-invoicing is mandated somewhere, it makes you compliant globally.
  • Faster Processing and Payment It takes on average 16 days to approve and pay a PDF invoice. On the flip side, electronic invoicing helps reduce these delays by streamlining the approval process. Once a customer receives your e-invoice, they can access it on their ERP system and route it on the spot for quicker approval. The ripple effect is that you get paid faster.
  • Increased Productivity and Automation E-invoicing enables you to send data straight to your customer’s AP system, eliminating manual entry. It is all done inside your software, so no need for any human interaction on your side. Because of this, your accounts department can focus on high-value activities. Further, electronic invoicing allows AP departments to validate invoices automatically before routing them to decision-makers for approval. Automatic validations help remove errors in crucial calculations such as VAT.
  • Better Account Reconciliation Reconciling invoices you’ve issued to your customers against their payments can be challenging. For one, your customers can decide to issue a single payment for multiple invoices. The payment amount may differ from the original invoices because of damaged goods and claim deductions. E-invoicing simplifies the account reconciliation process because it allows you to send the details of the invoices together with the payment.
  • Scalability E-invoicing is basically a programm code creating invoices and sending them in real-time with no limitations. Therefore it can easily be integrated into larger financial ecosystems, streamlining invoicing for all size of companies.

    Challenges When Converting PDF to E-invoice

    Converting PDF invoices to e-invoices can be challenging and companies should be aware of certain problems that can occur:

  • Losing important data
  • One major issue when attempting to convert PDF to e-invoice or other XML formats is the loss of crucial invoice data. PDFs are often inconsistent in design, and relying on OCR tools can lead to data extraction errors.

  • Formatting problems
  • Formatting issues are another problem when converting from PDF to XML. Because PDFs vary greatly in layout, converting them to XML can result in misplaced fields, incorrect data formatting, or incomplete conversions.

  • Validating an XML e-invoice
  • Once a PDF invoice has been converted to XML, it’s essential to validate the generated XML file to ensure compliance with the required standard, for example UBL.

     

     

    How to Transition from PDF to E-invoicing

    Some countries already mandate e-invoicing, some support it. Whatever the reason for transition is, here is the process how to integrate electronic invoicing into your system:

  • Assess Current Systems
  • Understand Regulations
  • Choose an E-invoicing Solution
  • Onboard Suppliers and Customers
  • Provide Training
  •  

    What if You Business Partner Can’t Send Them?

    You are using e-invoicing, but your trading partner cannot send an electronic invoice, whatever the reason may be. You can take the PDF invoice and manually upload it into the system. To streamline the process and make it easier it’s best to use one of the two tools:

  • OCR: often used to extract data from PDF invoices. However, OCR tools can misinterpret characters or formatting, leading to errors in the extracted data. This makes relying on OCR for converting PDFs to UBL or PEPPOL XML risky.
  • Electronic invoicing system, which is the most effective way to convert. Platforms allow businesses to input invoice data into a user-friendly interface, which then converts the data into the appropriate XML format, ensuring compliance with international standards and regulations.
