Electronic Invoicing in Czech Republic

Is e-invoicing mandatory in Czech Republic?

E-invoicing is partially mandatory in the B2G sector, where public authorities must accept e-invoices compliant with the EN standard, but are not mandated to require them from suppliers. In B2B, there is no mandatory requirement and e-invoicing is voluntary.

Who is affected?

• Public authorities: Must be able to process e-invoices in EU-standard formats for public procurement.
• Suppliers to government: Can send e-invoices voluntarily; no legal obligation.
• Businesses (B2B): Free to adopt e-invoicing with buyer consent.

Compliance requirements

In B2G, all public contracting authorities must use NEN platform, unless authorised to use a different procurement tool.

In B2B, there are no specific requirements for e-invoicing.

Standards & Platforms

Platform

The NEN platform is used to process B2G e-invoices for public procurement. All public contracting authorities must use NEN platform, unless authorised to use a different procurement tool.
