Step-by-Step Guide

1. Log in to the MyInvois Portal using your taxpayer credentials.



2. From the main menu, navigate to MyInvois > Preprod.



3. Go to the top-right corner and select View Taxpayer Profile.



4. Verify that the current taxpayer profile is the intended one for issuing e-invoices.

5. Verify the taxpayer again. You shall see the TIN, NRIC and Taxpayer name on top of the screen.

Idea
Tips
  1. The name must match exactly. Any missing characters, including dots (.) will result in a "Not Found" error.
  2. Multiple intermediaries can be added in the MyInvois Portal.
  3. Pay close attention to which TIN the authorization is made under, especially if you're using a company taxpayer profile. It's common for users to mistakenly authorize using the wrong profile.
  4. You can switch (change) taxpayer profiles within the MyInvois Portal.

  5. The "Date From" and "Date To" fields define the period during which the intermediary (Xilnex) is authorized to manage e-invoices. 
  6. For example, if the period is set from 1st Feb 2026 to 28th Feb 2026, any action performed outside this range will be rejected with an "Unauthorized" error upon submission.
  7. It is recommended to set "Date From" to the current date and "Date To" to 10 or 20 years later to avoid frequent updates.
  8. Permissions: Allow all.
  9. If you encounter an "Unauthorized" message in Xilnex, wait for about an hour to allow the cache to reset, then try again.
  10. If you're unsure about anything on the MyInvois Portal, you can contact the official authority for clarification.
