Information for suppliers

Electronic invoicing to our company is done through two channels based on the country where supplier comes from.

Czech suppliers – invoicing through data boxes in format ISDOC

• Information about data boxes
• Information about ISDOC format
• Specification of ISDOC format
• ID of our data box: d79ch2h
• Electronic signature included in the invoice is a must

Foreign suppliers – invoicing through email address efaktury@o2.cz

• Attachments are parts of email
• Invoice must be in format PDF, XLS, XLSX, DOC or DOCX
• Invoice cannot be sent by different channel at the same time
• Electronic signature included in the invoice is a must

If those conditions are not fulfilled, the invoice will not be accepted and processed. In case your invoice contains any attachments and both invoice and attachments are in one file, you can send more invoices in one email. Once the attachment is separated, please send each invoice with related attachment in individual email. In case of checking status of your invoices, please, contact our accounting department: zavazky@o2.cz
