If your e-Invoice won’t upload or the Submit button is disabled, here are the most common fixes:

1) Check your UUID

• The Unique Identifier Number (UUID) must follow the correct format (36 characters with hyphens).

• Copy it directly from the IRB MyInvois portal.

• Avoid extra spaces, missing characters, or typos.

2) Verify your file

• File format: PDF only

• File size: Must be 2 MB or smaller

• The file should not be corrupted or password-protected.

• Use a simple filename without special characters.

3) Complete required steps

• Fill in all mandatory fields on the upload form.

• Tick any required confirmation/declaration checkbox.

4) Try again if issues persist

• Refresh the page and retry.

• Use an incognito/private browser window or a different browser (Chrome, Edge, Firefox).

• Clear cache/cookies or temporarily disable extensions like ad-blockers.

By checking your UUID and PDF file, most upload issues can be resolved quickly.
