Czechia currently has no general mandatory B2B e-invoicing regime. Businesses can exchange electronic invoices voluntarily, provided the applicable requirements for authenticity, integrity, and readability are met.

Electronic invoicing is more established in the public sector, where Czechia has implemented requirements supporting structured electronic invoices in public procurement. For private-sector transactions, businesses can therefore continue using their existing invoicing methods while adopting structured e-invoicing voluntarily.

There is currently no general requirement for Czech businesses to issue structured electronic invoices for domestic B2B transactions.

Different rules apply when invoicing public-sector organisations. Suppliers participating in public procurement may be required to submit electronic invoices that meet the applicable European and Czech requirements. Businesses should therefore consider the recipient and type of transaction when determining which invoicing requirements apply.

For ordinary B2B transactions, electronic invoicing remains voluntary. Businesses using electronic invoices must ensure that invoices satisfy the general Czech VAT and accounting requirements, including the authenticity of origin, integrity of content and readability of the invoice.

Structured electronic invoicing requirements are more relevant to public procurement. Czech public authorities are able to receive and process electronic invoices compliant with the European EN 16931 standard.

Czechia does not currently operate a mandatory central B2B e-invoicing platform comparable to Poland's KSeF. Businesses therefore have greater flexibility in how electronic invoices are exchanged with their trading partners.

For structured e-invoicing, Czechia supports formats aligned with the European EN 16931 standard. The national ISDOC format is also widely associated with electronic invoicing in the Czech market, while other structured formats and exchange methods can be used depending on the requirements agreed between trading partners.
