Four steps to take now to meet the evolving e-invoicing regulations

In brief

• E-invoicing is set to transform the way businesses interact with tax authorities.
• Multinational businesses need a joined-up, cross-border approach to meet evolving regulations worldwide.
• Companies have an opportunity to streamline compliance and make the right technology choices.

E-invoicing is high on the agenda for tax administrations around the world. Several countries have already introduced some form of e-invoicing in the past few years, and by the end of the decade, much more are expected to follow.

The European Commission’s VAT in the Digital Age proposal (ViDA), which includes measures to modernize the Value Added Tax system, includes e-invoicing and digital reporting, which should give e-invoicing greater momentum.

One of the biggest challenges for multinational enterprises is coping with a range of local e-invoicing requirements. To make matters more complicated, the goalposts are constantly moving, with national authorities, such as France, Germany and Poland, delaying the introduction. Other countries are pushing ahead with their plans, such as Romania, where e-invoicing came into force in January 2024 and Malaysia, where the go-live date for e-invoicing of August 2024 is fast-approaching, with companies furiously striving to get ready. 

Even in countries that have had e-invoicing for several years, such as Brazil, Mexico, Italy and Saudi Arabia, regulations continue to evolve over time. 

Four ways companies should respond now

The introduction of e-invoicing is potentially transformative, with an impact on procurement and supplier relationships, cash collection and accounts payable, working capital, tax reporting, and wider digital transformation efforts. Companies need a well-defined implementation plan to comply with tax regulations on a daily basis. Here are some steps companies can take now to be ready for e-invoicing:

1. Define global tax policy and governance – and assign responsibilities

E-invoicing is evolving at different speeds in different countries. Businesses faced with a multitude of tax developments should develop an overall global tax policy that sets direction for the global and local tax functions. A task force of senior, multi-function representatives, backed with C-suite sponsorship, can agree tax policy and governance to meet evolving requirements.

Sanjeev Fernandez, EY Global E-invoicing and E-reporting Product Leader, emphasizes that it’s a whole business project. “It’s vital to engage stakeholders from the start and get them around the table, including IT and technology, finance, tax, legal, procurement, supply chain, sales and marketing, and general commercial,” he says. “There should ideally be a full-time project manager responsible for roll-out, to achieve compliance from day one of launch of e-invoicing in each country.”

The involvement of the finance department is critical to ensure smooth integration of e-invoicing into business operations, so that the funds flow aligns with the accounting reporting. Similarly, the additional technology and data requirements from e-invoicing will affect IT development projects, resources and budgets.

2. Assess readiness and start early

“Tax regulations and deadlines are changing continuously – in countries where e-invoicing has been around for a while, as well as those where it’s on its way,” says Amarjeet Singh, EY ASEAN Tax Leader. “So, it’s important to run current-state assessments of readiness of people, processes and systems for each country, highlight any gaps and develop plans in line with anticipated regulatory changes.” 

Once the team knows how e-invoicing affects the current invoicing system, they can bring in appropriate professionals to manage the change with limited business disruption. This allows them to onboard customers and suppliers seamlessly so that payments continue to flow in and out at the normal pace. 

Adopting e-invoicing is a major undertaking that can take as long as nine months, so businesses should start as early as possible. By continually monitoring regulatory developments, the project team can increase its chances of success and take a more holistic, longer-term view, to determine the implications for the business globally.

3. Strive for data quality and availability

“E-invoicing is a huge transformational journey. The key is to get the data right. By focusing on master data and tax determination, reviewing regularly, and automating as much as possible, everything else becomes easier.” says Dublin-based Deirdre Hogan, Partner, Head of Specialty Taxes, Ernst & Young Business Advisors.

Any transactional and accounting data sent to tax authorities should be accurate and complete to avoid penalties. Data quality and integrity is therefore a high priority, requiring strong data governance. E-invoicing is typically being introduced on a national level and each tax authority has different data requirements in terms of fields and formats. Once a go-live date has been announced, companies should carry out a gap analysis to determine whether they have access to the appropriate data and that the quality is reliable. Ideally, the process should be as automated as possible, with minimal or zero manual interventions. 

4. Choose the most suitable technology solution

Businesses have some big decisions to make regarding technology as they consider how to embed e-invoicing. According to Sanjeev Fernandez, EY Global E-invoicing and E-reporting Product Leader, “When it comes to technology for e-invoicing and e-reporting, companies need to be as strategic as possible. They need to elevate this initiative internally to handle a global footprint consistently. That way they can future-proof their operations, benefit from synergies and economies of scale, and avoid duplication of efforts and costs at a global level." 

The aim should be to have a global solution that can adapt to new markets and constant regulatory changes, and also to give central visibility over global transactions. However, the number of technology solutions can be overwhelming. 

The three options are to:

• Buy, either from global or local technology providers with the preference to implement and run it in-house
• Outsource to an external technology provider to implement and run it
• Build, which relies on internal resource to create, implement and manage end-to-end

Most companies choose a blend of buying and outsourcing. Then, it’s a question of what kind of technology partner to select. The first option is to work with global Enterprise Resource Planning (ERP) vendors to integrate e-invoicing into existing ERP to create a single, global system that can create invoices in different markets. The second alternative is to work with specialized, global middleware vendors to acquire middleware and software that links to a tax authority portal and can integrate smoothly into existing systems. The final option is to reach out to local middleware vendors, which is a good option for introducing e-invoicing into a single market and typically cheaper than a global vendor.
