The Submit button stays disabled until all required fields are valid and your file passes the system checks. Work through this quick checklist:

1) Validate your UUID

• Enter a valid UUID from the IRB MyInvois portal.

• Paste the UUID exactly as shown (usually 36 characters with hyphens), with no extra spaces or characters.

• Make sure the UUID matches the e‑Invoice you’re uploading.

2) Check your file

• File type: PDF only

• File size: 2 MB or smaller

• The PDF should not be password‑protected or corrupted.

• If it’s too large, re‑export or compress the PDF and try again.

• Use a simple filename (letters, numbers, underscores).

3) Complete any required fields

• If prompted, fill in all fields (e.g., amount, invoice number).

• Tick any declaration/confirmation checkbox before uploading.

4) Resolve common browser/session issues

• Refresh the page and try again from Payment → My Earnings Overview → Provide Validated e‑Invoice.

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

• Temporarily disable ad‑blockers/extensions that may block uploads.

• Sign out and back in if your session may have expired.
