The European Union is set to make a significant shift towards mandatory e-invoicing, with Germany set to implement it from January 1, 2025. This shift is also a strong indicator that other countries will soon follow, as e-invoicing becomes the standard across the EU in the near future. The move to e-invoicing is part of a broader EU initiative aimed at streamlining tax reporting, increasing transparency, and reducing fraud. For advertising agencies, the transition to e-invoicing could mean big changes to the way you handle billing, accounting, and client relationships. But with careful planning, your agency can turn this challenge into an opportunity for greater efficiency.
Here’s what you need to do to ensure your agency is ready for the shift to e-invoicing in the EU by 2025.
1. Understand the Legal Requirements
The first step to preparing for e-invoicing is understanding the new regulations. E-invoicing will become mandatory for business-to-business (B2B) transactions, and all invoices must follow a structured electronic format. That means the days of sending a simple PDF invoice are over.
Invoices will need to comply with the European standard EN 16931, which enables automated data extraction and processing. Specific formats like ZUGFeRD, XRechnung, Peppol BIS & EDI in Germany, or PEPPOL in other EU countries, are designed to ensure that e-invoices can be easily read and processed by both businesses and tax authorities. Get familiar with the format that will apply in your region or where your clients are based.
2. Assess Your Current Invoicing System
Now is the time to audit your agency’s current invoicing process. Are you still manually creating and sending invoices? Do you rely on PDFs or emails for billing? To comply with the new regulations, you’ll need to implement a structured digital invoicing solution.
Look at the software or systems your finance team is currently using. Do they support e-invoicing? If not, it’s essential to explore invoicing platforms that offer seamless integration with e-invoicing formats. Many accounting and enterprise resource planning (ERP) systems like Deltek WorkBook offer integrations to support e-invoicing, but you may need to upgrade or change your software to stay compliant.
3. Set a Timeline for Transition
With the deadline for mandatory e-invoicing just around the corner, it’s crucial to create a clear timeline for implementation. Break the transition into phases:
- 2024: Conduct your audit, select new invoicing software if needed, and train your teams.
- Early 2025: Begin transitioning a portion of your invoices to the e-invoicing format to ensure that everything runs smoothly. Consider starting with a few clients or projects to get comfortable with the system.
- Mid-2025: Have all invoices shifted to the new electronic format to ensure compliance by year-end.
By spreading the transition across several months, you’ll avoid the rush and reduce the risk of mistakes as the deadline approaches.
4. Train Your Finance and Operations Teams
Your finance team will be at the forefront of this transition, so training is crucial. Make sure your team understands how e-invoicing works, how to generate and send compliant invoices, and how to handle any exceptions.
Operations, project management and account management teams should also be looped in. Since project-based billing is common in ad agencies, ensuring that all project and account managers are aware of invoicing timelines, formats, and client requirements will help avoid delays or errors. Consider running internal workshops or bringing in external consultants to guide your team through the changes. Our Tangram team is made up of agency finance and operation experts, so we’d be happy to help support your transition.
5. Communicate with Your Clients and Partners
As you prepare to implement e-invoicing, it’s important to communicate with your clients, vendors, and partners. Let them know about the upcoming changes and ensure they’re prepared to receive and send e-invoices in the required format. Open a dialogue about how you’ll handle the transition and address any concerns they may have.
Many businesses will be making this transition at the same time, so collaboration with your clients will be key to ensuring a smooth process. Some clients may require additional support, particularly if they aren’t fully prepared for e-invoicing themselves.
6. Ensure Data Security and Compliance
As with any digital process, security should be a top priority. E-invoicing means handling sensitive financial data electronically, so it’s essential to ensure that your invoicing system complies with data protection regulations, including GDPR. Make sure your software or invoicing platform offers encryption and other security features to protect your data and that of your clients.
It’s also important to ensure that your e-invoices are compliant with local tax regulations. Each EU country may have slightly different requirements when it comes to tax codes and invoice formats, so you’ll need to tailor your e-invoicing process to meet the needs of each market in which you operate.
7. Monitor for Updates and Changes
E-invoicing regulations aren’t just an EU trend; other countries are also adopting similar requirements. As the EU continues to roll out its plan for improved tax reporting, it’s essential to stay informed about changes or additional requirements that could emerge both within Europe and globally.

Embrace the Opportunity for Efficiency
While the shift to mandatory e-invoicing may seem like an administrative challenge at first, it can actually lead to greater efficiency and cost savings for your agency. E-invoicing automates the entry of invoices into an ERP system and reduces the chances of errors, speeds up payment cycles, and improves cash flow visibility—all crucial for ad agencies working on tight budgets and project deadlines.
In fact, many agencies are finding that this shift offers an opportunity to streamline other financial processes, from expense tracking to project-based billing. By embracing digitalisation now, you’ll be positioning your agency for smoother operations in the future.
