As the global landscape of electronic invoicing continues to evolve, it's imperative for businesses to stay abreast of the latest developments and regulatory changes. In this review, we delve into significant updates from various countries around the world, shedding light on mandatory e-invoicing mandates, postponed launches, and new initiatives aimed at streamlining B2B transactions.

EU: No agreement on the VAT in the Digital Age

During the May Economic and Financial Affairs Council (ECOFIN) meeting, the VAT in the Digital Age (ViDA) legislative package, which includes regulations on Digital Reporting Requirements (DRR), once again faced a deadlock among the 27 EU member states. The sticking point remains the Platform Economy aspects, while the Digital Reporting Requirements section received unanimous approval.

Key Points on DRR:

  • Hybrid invoice: A new concept of "hybrid invoices" is introduced. These combine structured data (like digital formats) with unstructured data (like PDFs). As long as they include all required information in a structured format, they might be considered e-invoices.
  • Mandatory e-invoicing: This will be enforced for intra-EU business-to-business transactions (goods and services) starting July 1, 2030. However, it's contingent on a common EU definition for "e-invoice."
  • Member state authority: Individual EU countries can still regulate reporting beyond e-invoicing/e-reporting mandates. This includes maintaining existing SAF-T (Standard Audit File for Tax) requirements.
  • Domestic DRR: Lower standardization is expected for domestic (within-country) reporting obligations, allowing for some deviations from the EU model. This is expected by January 2030.
  • Alignment and deadline extension: Existing e-invoicing and real-time reporting mandates need to comply with the EU standard by January 2035. Additionally, the deadline to issue e-invoices for intra-EU transactions has been extended to 10 days after the chargeable event.

New report from Billentis

Billentis has published its new global e-invoicing and tax compliance report. The report, a follow-up to the previous report from 2019, provides a comprehensive analysis of the current landscape and outlook of electronic invoicing and related digital trade practices. The authors see a significant shift in the market landscape, with an accelerated transition towards universal electronic invoicing, fuelled by the demand for tax compliance.

Furthermore, the range of solutions is expanding beyond electronic invoicing to encompass Integrated Digital Trade, encapsulating the entire spectrum of transactions between buyers and sellers. Big influencers here are Artificial Intelligence (AI) and Environmental, Social, and Governance (ESG) factors. Within this context, Billentis has titled their report ‘Watch the Tornado’.

Poland: e-invoicing roll-out postponed till 2026

On April 26, 2024, the Polish Ministry of Finance completed an external audit of the National e-Invoice System (KSeF). The audit surfaced serious issues leading to the postponement of mandatory e-invoicing in Poland.

Initially set to launch on July 1, 2024, KSeF’s rollout has now been rescheduled, with a phased approach set to start on February 1, 2026, for large enterprises, and on April 1, 2026, for other businesses.

The audit highlighted serious errors in the KSeF's IT architecture and project management, including inadequate supervision by earlier administrators and poor maintenance of documentation. These findings prompted the decision to overhaul the system architecture thoroughly. The refreshed system is envisioned to be more reliable, secure, and functional, ensuring the security of economic transactions which is a priority for the Ministry.

Singapore's InvoiceNow initiative: Streamlining tax compliance

In a bid to modernize tax administration and simplify processes for businesses, Singapore is rolling out the InvoiceNow initiative, requiring GST-registered companies to transmit invoice data to the Inland Revenue Authority of Singapore (IRAS). This transition will be implemented gradually to ensure smooth adoption and compliance.

Introduced by the Infocomm Media Development Authority (IMDA) in 2019, InvoiceNow is a nationwide e-invoicing network based on the Peppol standard. It enables direct transmission of invoices in a structured format from one management system to another using the nationwide e-delivery network, based on Peppol, creating automation opportunities.

This allows both SMEs and large enterprises to enjoy smoother invoicing and faster payments, with reduced invoice processing time and no manual paperwork.  The InvoiceNow platform will be based on a five-corner model of Peppol – also called Peppol CTC. Taxpayers will be able to work with certified Peppol service providers. Invoices will be exchanged in a structured PINT SG format, and a copy must be sent to the IRAS.  

Singapore's e-invoicing commitment

Singapore launched its national e-invoicing network in 2019, based on the Peppol infrastructure, making it the first country outside Europe to use the European network to exchange e-invoices between private enterprises. To promote e-invoicing in Singapore, the body responsible for the country's e-invoicing system, IMDA, launched InvoiceNow, a series of initiatives including financial compensation for companies adopting e-invoicing. 

The Singaporean government is committed to moving away from paper invoices. Recently, Senior Minister of State Chee Hong Tat announced that “the Government will implement InvoiceNow as the default e-invoice submission channel for all government vendors within the next few years”. This means that InvoiceNow will replace the Vendors@Gov portal for registered businesses. 

The country's Peppol Authority, IMDA, is responsible for assigning access points and defining technical specifications for the e-invoicing system. Companies that would like to invoice electronically in Singapore must have an accredited access point and an e-invoicing system capable of sending invoices in the Peppol standard. 

Singapore's proactive approach to e-invoicing reflects its commitment to digital transformation and efficiency in tax administration. With the phased adoption of InvoiceNow and ongoing support, businesses are poised to embrace a new era of streamlined processes and enhanced compliance. 

Timeline Targeted Organizations
May 1, 2025 Early voluntary adoption by GST-registered companies.
Nov. 1, 2025 Newly incorporated companies voluntarily registering for GST.
Apr. 1, 2026 All new voluntary GST registrants.

Spain: likely delayed to early 2026

The rollout of B2B e-invoicing mandates in Spain, initially projected for mid-2025, faces delays likely pushing implementation to early 2026. Pending the necessary regulatory approvals, including a Ministerial Order defining syntax and technical specs for the Spanish Tax Administration's e-invoicing platform, the deadlines remain on hold.

Additionally, the VERIFACTU electronic invoice obligations planned for July 2025 are also likely to be delayed until early 2026.

The phased approach to mandates in Spain includes obligations for buyers to respond with invoice status updates like acceptance/rejection, full payment confirmation including the effective date of payment, and other optional statuses such as partial payments or third-party assignments.

Moreover, businesses issuing e-invoices must include a PDF document within 12 months of the Royal Decree's enforcement, unless the receiver consents to the original format. Buyers have a 4-day window to reject invoices; otherwise, they are considered accepted. When the full payment is made, buyers also need to send this information to the Spanish authorities.

Timeline Targeted Organizations
1 year after publication of Royal Decree in the Official Gazette Legal entities and sole traders with annual turnover of over 8M must issue and receive electronic invoices and comply with invoice statuses.
2 years after publication of Royal Decree in the Official Gazette Legal entities with annual turnover of less than 8M must issue and receive electronic invoices and comply with invoice statuses. For sole traders with the same turnover the invoice status requirement is not yet needed.
3 years after publication of Royal Decree in the Official Gazette All sole traders need to comply with invoice statuses.

USA: Joint declaration to enhance e-invoicing with EU

Following the sixth ministerial meeting of the Trade and Technology Council in Belgium (April 4-5, 2024), a Joint Declaration titled "Enhancing eInvoicing Interoperability between the United States and the European Union" was issued.

The Declaration affirms the intention for continued cooperation and efforts towards compatible e-invoicing between the US and the EU, which offer a range of benefits and have the potential to significantly reshape cross-market transactions and the dynamics of transatlantic trade.

To achieve increased interoperability, further discussions and alignment will focus on the flexibility of the data structure, payload alignment, and the establishment of roaming capabilities through service providers.
