XML format for Polish EDI invoice

Hi, 
In Country solution description for Poland, Cloud 25R published by ​@Bob Corrigan you can see:

“E-Invoice in Poland – (KseF) Poland is planning to introduce a National e-Invoice System (KSeF). The start date was originally planned to 1 July 2024, but the implementation has been postponed to a later date not yet communicated. The National e-Invoice System (KSeF) includes mandatory sending of e-invoices in a structured format to a governmental platform. The e-invoice is registered and assigned a unique reference number. A response will be sent back to the sender of the invoice including the status (approved/rejected) and the unique reference number. The buyer can retrieve the supplier invoice from the governmental platform. The solution is based on IFS Cloud eInvoice. A 3rd party service provider must be used to transform the invoice data into the KSeF structured format and to communicate with the authorities. The Polish e-invoice solution is developed in co-operation with Pagero. There will be additional development and deliveries as the scope of the mandate is clarified and communicated by the Polish authorities.”

The mandate for e-invoicing in Poland is set for February 2026 for larger businesses and April 2026 for the remaining businesses. Given this timeline, it is quite urgent to establish a working file format to facilitate the sending and receiving of e-invoices in Poland. Therefore, we would like to inquire if IFS has developed a file format for EDI that complies with the Polish legal requirements. If such a format exists, could you please provide information on where it can be found?

IFS Cloud 25R2 has several documents related to this.

KSeF, Krajowy System e-Faktur (National System of e-Invoices), is a platform intended for issuing and receiving invoices by electronic means. Using of KSeF platform is facultative. In 2026, issuing of B2B invoices via KSeF platform will become mandatory for domestic, EU as well as non-EU sales. For B2C invoices, it will be facultative. For large tax payers, issuing invoices via KSeF platform will be mandatory from February 2026. For other tax payers, it will be mandatory from April 2026. For micro businesses, it will be mandatory from 2027.

The solution is based on standard E-invoice process which is using a 3rd party service provider to handle the communication of invoice information. 

Enhancements have been introduced to IFS Cloud 25R2.

Companies in Poland, use basic Tax ID Number, without „PL” prefix, for domestic sales and export. For EU sales, Tax ID Number with „PL” prefix is used. Enhancements are introduced to better handle „PL” prefix when identitfying company and supplier for incoming e-Invoices.

Descriptions of Tax Categories are changed in connection to differences in handling 0%/No Tax categories between FA(2) and FA(3) KSeF invoice formats.

E-invoice Reference Number and QR code are available when printing invoices.

Support for E-invoice Reference Number when loading Supplier e-Invoice is added.

Thank you ​@Bob Corrigan but we are unable to access the link 

Send me your e-mail to bob.corrigan@ifs.com and I’ll send it to you.

As this is a legal requirement for Poland from next year, and there shooed be some Polish VAT registered companies that use IFS 10 - There is nothing built for 10, will it be done? or do we need to develop our own XML format that can be used for Poland? (we have Pagero as an intermediary)
