The advantages of e-invoicing in combination with an ERP system in Germany
The use of e-invoicing has been mandatory in Germany since January 1. For companies, this means a clear call to effectively integrate e-invoices into their business processes. The enormous potential of the combination of e-invoicing and ERP systems is particularly evident in a procure-to-pay process (P2P, purchase to payment). This integration opens up numerous opportunities to automate processes, reduce costs and create transparency. In this article, we take a detailed look at the P2P process, the general benefits of e-invoicing and the differences between incoming and outgoing invoices.
The procure-to-pay process and its integration with e-invoicing
The procure-to-pay process (P2P) covers the entire process from determining requirements to payment and forms an essential basis for efficient purchasing and invoice management. E-invoicing plays a central role here by supporting and optimizing every step in the P2P process. The five most important steps of the P2P process with a focus on e-invoicing are explained below:
Once the order has been placed, the goods or services are delivered. The receipt of goods is automatically recorded and documented in the ERP system. This documentation forms the basis for subsequent invoice verification and ensures that quantities, prices and delivery terms are complete and correct.
The core of the P2P process lies in automated invoice verification. Incoming invoices are digitally recorded and automatically compared with the order data and the goods receipt. Discrepancies, such as price discrepancies, are detected immediately and can be processed without delay. This step saves valuable time and significantly reduces manual intervention.
Definition: An electronic incoming invoice is sent to a company in digital form by suppliers or service providers.
Processing: E-invoices are automatically processed in the ERP system, checked and assigned to the corresponding purchase orders.
Advantages: Automated processing saves time, reduces errors and enables better traceability and faster payment processing.
Mandatory information: Both types of e-invoices must contain certain mandatory information such as the name and address of the issuer and recipient, invoice date, invoice number and the description of the goods or services.
Compliance: The e-invoice fulfills all legal requirements and offers maximum security thanks to digital signatures and encryption.
1. Automation and efficiency:
Manual entries are eliminated and all P2P steps - from ordering to payment - are seamlessly linked. This reduces errors and increases processing speed.
3. Faster payment processing:
Automation enables faster processing of invoices and payments, improving liquidity and strengthening supplier relationships.
5. Compliance and security:
E-invoices meet legal requirements and protect companies from errors, fraud and fines through digital signatures and encryption.
2. Cost savings:
Less manual effort, shorter processing times and the avoidance of paperwork lead to considerable cost savings.
4. Transparency and traceability:
Digital processing means that all steps in the P2P process can be monitored, which greatly improves traceability and control.
6. Environmental friendliness:
The digitization of invoice management contributes significantly to the reduction of paper consumption and supports sustainable business processes.
Conclusion
The mandatory introduction of e-invoicing in Germany has significantly accelerated the digital transformation in accounting. The combination of e-invoicing and an ERP system, particularly as part of a procure-to-pay process, enables companies to automate processes, reduce costs and create transparency. End-to-end integration from order to payment not only makes business processes more efficient, but also more sustainable and future-proof.
