Strahan Distribution service over five hundred schools throughout the twenty-six counties in Ireland. A medium sized company, they are one of the biggest suppliers to the woodwork department of Secondary schools, ETBs and Institutes of Technology in Ireland. They also supply to both the trade and the retail sector. Strahan Distribution embraced the opportunity to send eInvoices to the ETBs to speed up both the processing and payment of invoices. Strahan Distribution opted for the 3rd party Web Portal option as their preferred method of sending eInvoices to the ETBs.


Key Accounts personnel in Strahan Distribution are responsible for the creation and sending eInvoices using the Four-corner model and selected a semi automated solution from Pagero, a certified PEPPOL Access Point Provider. Strahan create their invoices in the usual way in their Finance System which are printed to the Pagero Virtual Printer which captures and encrypts and invoice data and sends it to Pagero Online where it is automatically transformed into the PEPPOL format and delivered to the Document Centric Solutions Ltd’s PEPPOL Access Point for delivery to the correct ETB. Strahan Distribution were guided by the Education Shared Business Services (ESBS) and Pagero with the testing and implementation.

4-Corner Model eInvoicing WorkFlow

The Four-corner method of sending eInvoices to the ETBs encountered a few issues with incorrect or missing data. The process of sending test data to check any eInvoice data that was incorrect was critical to the process and ensured that subsequent live eInvoices were uploaded and received correctly by the ETBs.


The Four-Corner model has proved convenient and efficient for the Accounts staff in Strahan Distributions as they can send eInvoices at their preferred times. The eInvoices are delivered directly and instantly into the Finance systems for each of the 16 ETBs. Strahan no longer send any paper invoices to the ETBs.

The application has an adapter that creates and sends PEPPOL compliant eInvoices to the DCS Access Point once the trips have been completed and approved for invoicing. Slevin’s coaches found the new Bus App system an efficient way to track and send eInvoices to the ETBs. eInvoices are processed quickly in the ETBs and once approved, payment is prompt.

The information provided using the app speeds up the approval process and the accuracy of eInvoicing and payment. "Slevins have been sending einvoices to the Longford Westmeath ETB and, in our opinion, it has improved the accuracy and speed at which Invoices are processed. We find that payment is also received more promptly".
