Efficient Implementation of E-Invoicing: Practical Guidelines for Businesses

The introduction of e-invoicing marks a significant step toward the digitization and increased efficiency of business processes. In an increasingly digital world, where companies are constantly striving to optimize their processes and reduce costs, e-invoicing offers an innovative solution for simplifying and accelerating accounting. The transition to e-invoicing affects domestically based companies that provide or utilize taxable and tax-exempt B2B services within the meaning of Section 4(1) to (7) of the German Value-Added Tax Act (UStG) and domestic transactions under Section 13b of the UStG.

However, in addition to the obvious advantages in terms of efficiency and sustainability, the transition to electronic invoicing also presents a number of challenges that companies must address. Below, we outline how the transition affects individual business areas. We have also summarized detailed instructions in the following PDF: Transition to E-Invoicing (PDF)

Purchasing

The transition to e-invoicing begins in purchasing with the order. Integrating the order number into the e-invoice enables automatic reconciliation with the ERP system, ensuring the accuracy of quantity and price. Furthermore, integrating the goods receipt into the system allows for a comparison with the actual quantity delivered, which increases the accuracy and efficiency of the ordering processes.

The information contained in the purchase order, such as the goods or service numbers and the delivery address, is essential for correct tax calculation. In international transactions, correct registration abroad is crucial to ensure tax compliance. Here, SAP plays an important role, as it supports cross-border tax schemes and simplifies the management of delivery addresses and VAT ID numbers.

Merchandise Management

Merchandise management benefits from digitalization through the integration of order data. A comparison of order numbers enables precise tax calculation and ensures that the goods are sent to the correct delivery address. Intrastat declarations are required for intra-Community acquisitions, which are often prepared by the tax department in collaboration with the merchandise management team. Maintaining data in the merchandise management system facilitates the preparation of these declarations and prevents manual errors.

Accounting

Accounting plays a central role in verifying and posting e-invoices. Automated checks for completeness and accuracy of invoices can identify and reject incorrect or incomplete invoices early on. Regularly reviewing vendor master data, including VAT ID numbers, is essential for optimizing tax calculations. Additionally, software for validating VAT ID numbers can help ensure the accuracy of tax information.

ERP System

ERP systems are the heart of data integration and tax calculation within a company. They enable the linking of purchase orders, goods receipts, and invoices, ensuring a seamless flow of data. Add-ons and tax engines can help extract the necessary information and automate tax calculation. An invoice verification workflow ensures that invoices are processed correctly and efficiently, even in the event of discrepancies.

Tax

The tax department performs a control function, particularly for invoices without a separate VAT line item, to ensure that the tax liability is correctly reversed. Plausibility checks and random spot checks help prevent errors and ensure tax compliance. The correct maintenance and use of tax codes in the ERP system are of central importance here.

Special Considerations for the Introduction of E-Invoicing

The introduction of e-invoicing brings special challenges, particularly in sectors such as retail or the restaurant industry, where e-invoices are not issued as standard. Pragmatic solutions must be found here to facilitate the transition. Input tax deduction remains of central importance despite the introduction of e-invoicing. Erroneous e-invoices must be rejected, while error-free invoices allow for input tax deduction even in the presence of technical defects.

In summary, the switch to e-invoicing requires close collaboration between purchasing, inventory management, accounting, and the tax department to ensure smooth integration and accurate tax calculation. Automated processes and regular audits help increase efficiency and ensure compliance.
