Post-Tender Due Diligence in South Africa: The Verification Checklist

Post-Tender Due Diligence in South Africa: The Verification Checklist

Key takeaways

  • Winning bidders are verified after submission—errors can still cost you the award.
  • Due diligence checks tax, B-BBEE, CSD, banking, and past performance.
  • Prepare verification packs before submission to avoid delays.
  • Consistent data across documents reduces red flags and award delays.

Submitting a tender doesn’t end the process. Many South African organs of state perform post-tender due diligence before issuing the award. If your data doesn’t match, your bid can be disqualified—even after you score highest.

What is post-tender due diligence?

It’s a verification process that confirms your compliance claims are true. The evaluation committee checks your documentation against official databases.

The verification checklist

  • Tax status: Confirm your TCC PIN shows “Tax Compliant.” See the SARS tax clearance guide.
  • CSD status: Must be active and verified. Review the CSD guide.
  • B-BBEE: Certificate or affidavit must be valid and current.
  • Banking details: Must match CSD and bank confirmation letter.
  • Past performance: References and completion letters should match your submission.

Common red flags that delay awards

  • Different director details across CIPC, CSD, and your proposal.
  • Expired certificates or conflicting dates.
  • Unverifiable reference contacts.

How to prepare before you submit

  • Create a verification pack with all compliance documents.
  • Check expiration dates at least 30 days before submission.
  • Keep your CSD, SARS, and B-BBEE data consistent across all documents.

Compliance failures can be treated as misrepresentation. Avoid risk by reviewing fraud red flags and cleaning up your data.
