E-invoice compliance means keeping up with rapidly evolving government mandates for how invoices are created, exchanged, reported and stored. These rules align with tax laws, enforce specific formats and often require real-time reporting and strict data accuracy.
Compliance isn’t just a box to check — it’s a chance to streamline operations. E-invoicing reduces manual effort, improves accuracy and drives automation at scale. With the right solution in place, you stay ahead of shifting regulations while cutting costs and unlocking lasting business value.
What Makes E-invoice Compliance Challenging
- All e-invoice mandates are different
- E-invoice mandates vary by invoice type (B2B, B2G, B2C, G2B, G2C)
- Mandates do not always resolve invoice exchange challenges (paper, email, portals, EDI, e-invoice networks)
- Mandates are continuously evolving and subject to change
- Mandates can divert focus from core business strategy
- Compliant invoices may not fully meet specific business needs
- Noncompliance can lead to significant fines or operational disruptions
- Localization requirements often demand specialized local expertise
- Implementing changes to ERP systems can be complex and costly
- Adapting to mandates requires significant investment

Interoperability
This model separates tax reporting from e-invoice regulation. Businesses use four-corner models and open networks, supported by a long history of e-invoicing adoption.
Examples: Nordics
- Tax reporting occurs post-audit
- E-invoice exchange is flexible
- Open, decentralized infrastructure
Real-Time Reporting
In this model, tax reporting must occur in real or near real time as invoices are issued. Exchange methods may vary and are not always regulated.
Examples: Hungary
- Real-time tax data submission
- E-invoice exchange not mandated
- Certified providers often used
Clearance Model
This approach requires tax reporting to be built into the invoicing process. Invoices must be issued via a government platform, and only certified providers are allowed.
Examples: India, LATAM
- Government-managed invoice issuance
- Certified providers required
- Exchange channels not regulated
Centralized Exchange (CTC)
Invoices are issued and exchanged directly within a government platform. Tax reporting is integrated and certified providers are mandated.
Examples: Italy, Poland (2026)
- Full government platform integration
- Certified providers only
- Streamlined, centralized system
Decentralized CTC
This emerging model combines mandatory tax reporting with regulated but decentralized invoice exchange. Only certified providers with special roles may operate.
Examples: France (2026)
- Integrated tax reporting
- Regulated invoice exchange
- Decentralized network via approved providers
