Authority: Approved by NTPC as a third-party agency for authentication of tender documents

Overview

Large public sector tenders set qualifying requirements: a bidder must show it has supplied similar equipment, executed similar works or achieved certain performance. The evidence is usually a set of purchase orders, work orders and client certificates. To guard against inflated or forged credentials, many buyers require these documents to be verified and authenticated by an independent agency before the bid is assessed.

Aaditech is approved by NTPC as a third-party agency for authentication of tender documents. We verify bidders’ qualifying documents objectively and record our findings in a form the tendering authority can rely on.

Note: We verify that documents are genuine and consistent. We do not evaluate bids, and the decision on whether a bidder qualifies always rests with the tendering organisation.

What we verify

DocumentWhat we check
Purchase orders and work ordersIssuing organisation, reference numbers, dates, scope, quantities and values
Contract agreementsParties, scope and execution details
Completion and performance certificatesIssued by the stated client, matching the order, signed by an authorised person
Supply and execution recordsConsistency between orders, invoices and certificates where requested
Supporting credentialsOther documents that the tender’s qualifying requirements call for

Where the tender conditions require it, we confirm the authenticity of a document directly with the organisation that issued it.

Common problems we see

Most delays in authentication come from avoidable gaps rather than doubtful documents. The ones we meet most often are:

  • Incomplete sets. A completion certificate is submitted without the order it relates to, or an order is submitted without proof that it was executed.
  • Mismatched details. Quantities, ratings or dates differ between the order and the certificate, or the company name has changed since the order was placed.
  • Unclear authority. A certificate is signed by someone whose designation or authority is not stated.
  • Wrong format. The tender asks for documents to be authenticated in a particular way, and the bidder’s papers do not match it.

Raising these points early gives bidders time to obtain clarifications from their clients before the bid deadline.

Who it’s for

  • Bidders for NTPC and other tenders that require third-party authentication of qualifying documents.
  • Manufacturers and contractors preparing a credentials file for several upcoming tenders.
  • Tendering organisations wanting an independent check on documents submitted to them.

Our process

  1. Tender review. We read the qualifying requirements and the authentication clause to understand exactly what must be verified and in what form.
  2. Document collection. The bidder provides the documents and the contact details of the issuing organisations.
  3. Scrutiny. We examine each document for completeness and internal consistency, and against the qualifying requirement it is meant to support.
  4. Confirmation with issuers. Where required, we seek confirmation from the issuing organisation.
  5. Authentication. We sign and stamp verified documents, or issue a verification report, in the format the tender requires.
  6. Record keeping. We keep a record of the verification so it can be referred to if the tendering authority raises a query.

Frequently asked questions

Why do tenders ask for third-party document authentication?

Buyers need confidence that the purchase orders, work orders and completion certificates submitted to meet qualifying requirements are genuine. An independent agency verifies them before the bid is evaluated.

Is Aaditech approved by NTPC for this?

Yes. NTPC has approved Aaditech as a third-party agency for authentication of tender documents.

Which documents are typically verified?

Purchase and work orders, contract agreements, completion and performance certificates from clients, and other credentials submitted against the tender's qualifying requirements.

Can you guarantee our bid will qualify?

No. We verify whether documents are authentic and consistent. Whether a bidder meets the qualifying requirements is decided by the tendering organisation.

Do you verify documents for buyers other than NTPC?

Yes, where the tendering organisation accepts an independent agency. Please check the tender conditions, which usually name the agencies or the type of agency acceptable.
