E-invoicing is becoming mandatory around the world

From paper invoices to PDFs to structured digital data, the way businesses send and receive invoices is changing. Governments aren't just encouraging that shift, many are legislating it, with specific systems, formats, and deadlines businesses are required to meet.

For some businesses, e-invoicing is already mandatory. For others, it's being introduced over the coming years. The details vary by country, but the direction is clear: invoices are becoming data that business systems can validate, process, and report, not just documents that people send and read.

What is e-invoicing?

An e-invoice is a structured digital invoice exchanged directly between a seller's and buyer's systems through an approved network or platform.

That's different from sending a PDF by email, or even routing a PDF through an approved platform. The channel isn't the issue; the format is. A PDF is built for people to read: a total, a date, a line item, all laid out visually. There's no structured data underneath for a system to validate. A structured e-invoice solves that. Using standardised formats like UBL or CII, it tells software exactly what each piece of data means: the total, the currency, the tax. Systems can read that and act on it automatically.

That precision is what makes it possible to validate, route, match, approve, and record invoices with far less manual work. Depending on the country, some or all of that data may also need to reach a tax authority directly.

Why is e-invoicing becoming more important?

E-invoicing is part of a broader shift towards digital tax administration. Governments are introducing it to close tax gaps, reduce fraud, get more timely and consistent transaction data, and cut the administrative burden of processing invoices.

For businesses, the benefits go well beyond compliance. Structured invoice data lands directly in your systems, so there's no manual entry, and automatic validation catches mismatches before they turn into disputes or late payments. That same structure is what makes the whole process faster: invoices move through approval and reconciliation in a fraction of the time manual processing takes, and travelling through certified, encrypted networks instead of open email makes them harder to tamper with or fake along the way. The result is a system that's easier to trust: every invoice is time-stamped, tracked, and visible across invoicing, approval, payment, and accounting, so there's one source of truth instead of four teams reconciling different versions of it.

However, e-invoicing creates new operational requirements, and what's actually required differs significantly depending on where you operate.

What does e-invoicing look like around the world?

There is no single global e-invoicing mandate. Requirements differ by country and may differ again by entity type, transaction type, industry, annual turnover, or tax registration status.

The main areas of variation include:

• Scope: Some rules apply to business-to-business transactions, while others also cover business-to-government, business-to-consumer, or cross-border transactions.

• Direction: A mandate may require a business to receive e-invoices, issue them, or do both.

• Timing: Some countries have already implemented e-invoicing. Others are introducing phased obligations based on company size or sector.

• Format: Countries may require specific structured formats, such as UBL, CII or Factur-X, or a local implementation of a wider standard.

• Network: Invoices may need to pass through a government portal, a certified access point, an accredited platform, or a network such as Peppol.

• Reporting: Some regimes require the full invoice to be exchanged through the network. Others require selected transaction data to be reported separately.

Here's how that plays out by region:

• Europe: Italy has operated a nationwide electronic invoicing and clearance model for several years. France is introducing a phased model in which French businesses must be able to receive e-invoices from September 2026, with issuing and reporting obligations also phased by company size. Germany already requires businesses to accept e-invoices, with issuing obligations phasing in through 2027 to 2028. The UK is moving towards a mandate of its own, planned for 2029.

• Asia-Pacific: Currently, Singapore's mandate is e-reporting, not e-invoicing: GST-registered businesses must separately report invoice data to the tax authority through InvoiceNow, its national Peppol-based network, even though the invoice sent to the customer doesn't have to change. Malaysia is phasing in its own mandate based on annual turnover, and other markets in the region are still developing their approach.

• Latin America: Most of the region already has mandatory e-invoicing in place, including Brazil, Mexico, Chile, Colombia, Argentina, and Peru.

These examples are illustrative, not exhaustive. Regulations, deadlines, and technical requirements can change, so it’s important for businesses to confirm their obligations with their relevant local authority or tax adviser.

How can businesses prepare?

Even when there's no domestic mandate yet, preparation still matters if you invoice or get invoiced by businesses in markets that do have one. A practical starting point:

• Identify what's in scope. Map the countries where you're established, tax-registered, or trading with local customers and suppliers, then work out which entities issue, receive, or report invoices in each market.

• Understand the local rules. Confirm deadlines, required fields, formats, networks, and reporting obligations. A solution that works in one country may not meet another's requirements.

• Clean up your data. Accurate entity details, tax IDs, and customer and supplier records matter more once invoices are validated automatically. Bad data means rejected invoices and payment delays.

• Plan beyond domestic B2B. Cross-border, business-to-consumer, and marketplace transactions often carry separate reporting or invoicing rules.

• Check your systems. Make sure your accounting, ERP, billing, and accounts payable tools can create, receive, validate, and store structured e-invoices, and map how they'll move through approval and reconciliation.

Airwallex is rolling out e-invoicing support

Doing all of this alone, market by market, is a lot for any business to take on. That’s exactly why Airwallex is building connections with each region's relevant invoicing system directly into billing and spend workflows.

Our first phase of support will begin with France, as businesses must be able to receive structured e-invoices from 1 September 2026.

VAT-registered businesses established in France will be able to receive and process e-invoices through Airwallex Spend and Airwallex Billing. We'll expand to more markets and workflows over time, with product coverage, eligibility, and timing varying by region. Airwallex will manage the product and network connections needed for each market, and we'll share documentation and updates as each market comes online, so you know what's supported, when, and what's needed to set up.

E-invoicing is a global shift, but not a single global switch. Wherever you operate, the best place to start is understanding your own obligations, and we'll share updates as new markets come online.
