Tips for preparing

  1. Apply for your financial seal or e-signature first; e-invoice setup depends on it.
  2. If you don't have a KEP address, get one now; several marketplaces require it.
  3. Collect the documents as clear, up-to-date PDFs in a single folder.
  4. Keep your company stamp ready to stamp and sign contracts.
  5. Never share your passwords; we do the necessary steps together in a meeting.

This list is based on the platforms' publicly available information. Platforms may change their document lists from time to time; we check the current list with you during each application.
