Pricing: Must be firm, inclusive of VAT, and valid for 60 days from RFQ closing date. Payment terms: Standard 30 days from invoice receipt date (as a Schedule 3A public entity). Advance payments: Require a payment guarantee approved by iThemba Labs Finance. Shorter payment terms (7/14 days from delivery) may be negotiated but require a Payment Guarantee to mitigate risks. Currency: ZAR. Pricing schedule must include: model, quantity, price per unit (VAT incl.), delivery fees, and total (VAT incl.).

Mandatory: Registration on the National Treasury’s Central Supplier Database (CSD) (www.csd.gov.za) — bids from unregistered suppliers will not be considered. Tax compliance: Verified via CSD and tax-compliant status PIN. No bids awarded to non-tax-compliant entities. B-BBEE: Submit SANAS-accredited certificate or sworn affidavit to claim preference points. Forms: SBD 4 (Bidder Disclosure) and SBD 6.1 (Preference Points Claim) must be signed and completed. Disqualification risks: Failure to provide mandatory documents, listing in the Register for Tender Defaulters or List of Restricted Suppliers, or fraudulent claims.

Payment conditions: Standard terms are 30 days from invoice receipt date. Advance payments require a guarantee approved by iThemba Labs Finance. Shorter payment terms (7/14 days from delivery) may be mutually agreed but require a Payment Guarantee. Delivery: Firm delivery period must be specified. Late submissions are not accepted.
