Turkey has taken the lead in implementing e-invoicing in the region. The Turkish Revenue Administration mandates the use of e-invoices for all transaction types, including cross-border transactions, for businesses that deal with other businesses (B2B), consumers (B2C), and government (B2G) entities. The requirements add complexity for taxpayers, such as determining the document type based on the recipient's tax identification number and sending documents using their aliases, which require constant updating. Additionally, foreign companies may find it challenging to comply with the e-archiving regulations.


Fonoa e-invoicing provides a comprehensive and indispensable solution for businesses operating in Turkey. Our tailored offering addresses the unique challenges of e-invoicing implementation in Turkey. We excel in simplifying the process by automating essential tasks such as e-fatura/e-arsiv registration checks. Moreover, we understand the importance of local compliance, so we facilitate the local storage of e-invoices within Turkey. With Fonoa e-invoicing, you can trust that your business will meet regulatory requirements and operate efficiently and effectively in the Turkish market.

What does
Fonoa offer?

  • Decide document type to issue

    Determining the correct document to issue can be challenging especially for B2B as it requires knowing whether the business is registered or not.

    We understand the complexity of the process and thus clients only need to share with us the tax id (VKN or TCKN) without any further definitions. We then determine the correct type of document that has to be issued.

  • Handle invoice numbering

    Invoice numbering rules can be confusing especially when it’s based on the document type being issued.

    Since Fonoa handles the decision of which document has to be issued, we also take care of the numbering sequences ensuring they are compliant.

  • Identify correct aliases

    Taxpayers who have multiple branches or multiple private integrators might have more than one mailbox (alias), which can be challenging because suppliers must send invoices to the correct aliases and if databases are not updated it could result in rejections by the TRA

    Fonoa uses the tax id to identify the correct alias and use it to prevent rejections from the first trial.

  • Comply with e-Archiving rules

    Storing original e-invoices locally in Turkey might present challenges to some international companies whose headquarters and storage locations are located abroad.

    Fonoa automates tax compliant long-term electronic archiving in line with country specific regulations and longer if needed. We also store documents in the format required and it can be easily accessed through the user interface. Share access and the results to external stakeholders such as i.e. auditors.
