The Peppol e-Invoicing Revolution


In order to achieve better enforcement of VAT legislation, various governments worldwide, in conjunction with one another, decided approximately 15 years ago to issue a number of new e-Invoicing rules.

It was decided, for instance, that PDF invoices would no longer be legally valid as of a date yet to be determined, but would be replaced by invoices in a structured format, such as UBL, Peppol BIS Billing 3.0 or other structured invoice formats. It was also decided that the exchange of these invoices would be required to take place via the Peppol network or other related networks.

Please note, that for the sake of brevity, on this website we use the terms UBL as a collective name for all structured invoice formats related to UBL and Peppol as a collective name for all Networks related to Peppol.

All e-Invoicing stakeholders from the concerned countries, such as suppliers of ERP software and e-Invoicing service providers, were requested to comply with the newly issued rules, when developing new e-Invoicing software and -services. The stakeholders have naturally agreed to this.

In addition to the definitions for Invoice Formats and Distribution Networks, the authorities have also issued a quadrilateral Peppol e-Invoicing schema as a guideline for the development of new software and services, which shows the route that e-Invoices follow when sent from supplier via Peppol to the customer.


This schema looks as follows:

It was assumed that e-Invoicing service providers would develop new e-Invoicing systems, but this has only happened to a very limited extent.

Most e-Invoicing service providers focused on providing manpower services, to help process the increased workload resulting from the new e-Invoicing rules.
As a result, very few Peppol e-Invoicing systems have been developed over the past 15 years, causing the results achieved in the adoption of Peppol e-Invoicing to be very mediocre. And this moderate success is prompting many government bodies to proceed, now or in the short term, to making Peppol e-Invoicing mandatory.

Unlike many other e-Invoicing providers, we have chosen to design a fully functional model based on the provided quadrilateral model, and to develop a fully functioning allround Web App based on that model that automates and digitizes entire Procurement Processes.

Below the Peppol e-Invoicing model developed by us, on which we based the development of our Procurement Document Manager App.


As you can see, our PDM model is clearly based on the quadrilateral model provided by the government authorities, to which we have added a large number of specific procurement functionalities. We have also included a Database in our PDM model, where all procurement documents are stored.

It is also defined in our model that every UBL invoice is always accompanied by a PDF invoice. This was done because UBL invoices are extremely suitable for visualizing VAT flows between companies as required by tax authorities, but for accountants, for bookkeeping purposes they are unsuitable. UBL invoices naturally remain the legally valid invoices, whereas PDF invoices play only a supporting role.

The Procurement Document Manager App, abbreviated PDM
As mentioned above, we have developed a Web App, based on our above shown model, and the App is called: Procurement Document Manager, abbreviated PDM.

The PDM App Automates, Digitizes, and Optimizes Procurement Processes, enabling companies to comply with the new government Peppol e-Invoicing regulations very easily, efficiently, and cost-effectively.

The sophisticated design of our PDM App not only enables companies to easily comply with the Peppol e-Invoicing guidelines, but it also yields a whole range of other additional benefits.
Because procurement documents no longer need to be printed, a large number of other benefits appear, such as:
-A significant lower environmental impact, because no more paper is used.
-Paper and Printer costs are eliminated.
-Significant savings on personnel costs, because unprinted documents don't need to be processed like: printing and storage in folders and in archives.
-Space savings, because the cabinets and rooms where these documents were stored and archived no longer need to be used for that purpose.

The PDM schema shows that All Procurement documents, including those documents that Are not exchanged via Peppol Providers, but are part of the procurement process, are stored in the PDM database. This may involve waybills, delivery notes, delivery notes, correspondence between supplier and customer, but also photos of documents that are not available in digital form but only on paper, these documents can then be digitized by taking photos and incorporated into the PDM process.

All e-Invoices (PDF, UBL, Incoming and Outgoing) and underlying documents are easily traceable and accessible from the PDM database throughout the entire fiscal retention period of administrations, this in contrast to current practice, in which invoices are stored unstructured on hard drives or in dusty archives, where they are difficult to trace and to access.

Documents uploaded to the PDM App are assigned to shared dossiers of related documents by the PDM user, just as paper procurement documents were collected in shared folders.

PDM users determine for themselves based on which properties the folders are created, but folders are often created based on purchase and sales orders, in order to enable validation of purchase invoices or the invoicing of sales orders.

Within the PDM App, dossiers can be traced within a few seconds by searching by name or date, which offers a huge advantage in terms of workload compared to the old-fashioned manual search for paper folders, where it often takes minutes before the correct folder is found.

Within the PDM App, overviews of Incomplete Dossiers can be created, which are dossiers to which no purchase or sales invoice has yet been added. Incomplete Dossiers provide a way to detect Sales Orders Yet to Be Invoiced, thereby reducing the risk of forgotten invoicing. Additionally Incomplete Dossier overviews provide a way to detect purchase invoices yet to be received.

We estimate that deploying the PDM App in companies can lead to a reduction of 40 to 50 percent in the number of hours to be spent on procurement.

The PDM model is founded on the vision that a successful digitization of the procurement process is only possible when ALL procurement documents and ALL procurement operations that are part of the procurement process are included in the PDM model, therefore, PDM even supports functions that lie at the very edge of procurement, such as the coding of e-Invoices.

Journal entries created in the PDM App are digital in nature, and can therefore potentially, be automatically read into ERP Apps, which in turn increases the efficiency of using the PDM App. Of course this function is only available when supported by the ERP App as well.

The fact that PDM is a WEB App also brings additional efficiency benefits within the procurement process. For instance because tasks such as approving purchase invoices can be handled via the internet, preventing bottlenecks in the procurement process to occur, because those required to approve the invoices are not present at the office.

Additionally, external parties such as accountants and tax inspectors can also access documents in the PDM App via the internet, further fulfilling the purpose for which Peppol e-Invoicing was created, namely improving the enforcement of VAT legislation by the tax authorities.

Introduction to the PDM App
If what we mentioned above about the PDM App sounds too good to be true, we offer you the opportunity here to eliminate any doubt: The PDM App can be used and evaluated Live from this website.
And to give you a head start with your first use of the PDM App, we go through two practical exercises below that you can perform in the PDM app.

The first exercise shows how UBL invoices are displayed within the PDM App, and to perform the exercise, do the following:
Click on: "PDM App" at the very top left of the menu on this page and then click on "Login" on the right page to log in to the PDM App. You will then arrive at a page in the PDM App displaying a list of uploaded documents. You can display each document in the list in PDF or UBL with just one click on the concerning button.

In the second exercise, we demonstrate how to upload UBL/PDF e-invoice pairs to the PDM App:
To do this, click on "Upload UBL+PDF Docs." in the left menu, then on “choose files”, select 1 UBL file with the extension of (XML or JSON) and 1 file with the PDF extension, and then click on "Open" to upload the files to the PDM App.

You will receive a notification when the files have been uploaded successfully. Next, click on "Assignable Documents" in the left menu, after which you will arrive at the same page you visited earlier, but which now also lists the documents you uploaded. You can now view these documents in UBL or PDF as well.

If you wish to evaluate the PDM App Exclusive and Intensive, you can request a free evaluation period of 2 months, see further down this page.

When evaluating the PDM App on this website, please do not pay attention to the type or content of documents displayed in the App, because, as you have been able to observe yourself, the PDM App on this website is publicly accessible and any website visitor can upload any document to the PDM App, meaning there is no logical correlation between the documents in the App.

The PDM e-Invoicing and Sustainability Revolution
The PDM App can result in a gigantic Peppol e-Invoicing revolution, and it also brings enormous Environmental and Sustainability benefits, especially when used on a large scale, and therefore we hereby invite everyone to request a free 2-month PDM trial period from us as quickly and en masse as possible.

Anyone who has tested and reviewed the PDM App on this website will have experienced that it is a wonderful App that supports all the necessary and desired Procurement functions required for a smooth, fast, and efficient completion of procurement processes. You will also have been able to determine that every UBL purchase or sales invoice, along with its corresponding PDF invoice, can be easily traced and displayed, ensuring that tax inspectors looking to improve their control of VAT legislation implementation, have all the necessary information at their disposal.

What more could governments and businesses wish for to get Peppol e-invoicing up and running, and as a bonus, also make a significant contribution to the environment and sustainability.
We would like to ask every government considering making Peppol e-Invoicing mandatory to first to first familiarize themselves with our PDM app, and conclude that making Peppol e-Invoicing mandatory can be omitted, because our PDM app supports Peppol e-Invoicing excellently, while simultaneously leading to enormous efficiency improvements and cost savings for businesses.
As a result, companies will voluntarily start using the PDM App and thereby implicitly support Peppol e-Invoicing, without having to be forced to do so.

Evaluation of the PDM App
The PDM App is a WebApp that runs on external WebServers, and therefore No PDM Software needs to be installed on your systems to evaluate or use PDM.

The PDM App is a WebApp available in the English language, making it easy to roll out worldwide.

PDM is intuitive to use and moreover, every page within the PDM app provides an explanation of the purpose and use of the respective page and the relationship between the various pages. Should you require further explanation, we are naturally willing to provide it.

The free evaluation entails no obligation whatsoever, you can stop the evaluation at any time and delete your entered documents from the PDM app. And if you decide to continue using the PDM App after 2 months, you simply pick up where you left off during the evaluation period.

The only thing you need to do now is request an evaluation, so you can start evaluating the PDM App in a few days.
