Three perspectives, one success story: Customer and partner in joint exchange
The Westfalen AG has developed its international e-invoicing solution in partnership with GOpus and ecosio Implemented. This very team is now standing together on the virtual stage, offering three perspectives on the same project: requirements, SAP integration, and international data transfer.
| 🏭 Westfalen AG | ⚙️ GOpus | 🌐 ecosio |
| The requirements from day-to-day business: What did the solution have to deliver, what really mattered in the company, and what would be done differently today? | The SAP side: How Gopus eInvoice how it was integrated into the existing SAP ECC landscape and how the E-Invoice Monitor creates transparency directly in SAP. | The compliance side: Validation according to country-specific requirements, routing and transmission via Peppol plus fast connection of other countries. |
The initial situation – does it perhaps sound familiar to you?
Invoices are sent by post, email, PDF, and EDI. Manual uploads to national government portals are required. There's no continuous overview of delivery status. And simultaneously, new obligations are being introduced in Germany, Austria, Belgium, and the Netherlands. All while, in the background, the migration from SAP ECC to S/4HANA is being prepared.
