• We accept X12 835 files.
• All ERAs should be placed in a date-named folder corresponding to the submission date.
  • Folders should use the YYYY-MM-DD format.
  • Example: An ERA submitted on April 21, 2026 should be placed in a folder entitled:2026-04-21/
• Do not place files in the root directory.
