01
Common registration and compliance documents
Frequently requested records include constitution documents, PAN, GST, Udyam where claimed, EPF/ESIC or labour registrations where applicable, contractor enlistment, authorization and bank details. A document is useful only when it belongs to the bidding entity, is valid on the required date and proves the exact condition.
Practical checks
- Create an expiry register for all certificates.
- Keep legal name and address consistent.
- Upload only the evidence requested in the proper cover.

Declarations, affidavits and authority

Power of attorney, board authorization, notarization, stamp paper and letterhead requirements must follow the prescribed format exactly.
Practical checks
- Do not rewrite mandatory prescribed language casually.
- Confirm the authorized signatory named in portal records.
- Use the tender’s annexure rather than an old template.

Financial and banking evidence

The required financial years, certificate date, bank format and UDIN requirements come from the tender—not from a general checklist.
Practical checks

- Use the exact financial-year range.
- Explain permitted restatements or entity changes with evidence.

Practical checks
- Verify legibility after compression.
- Keep the original signed files and final upload set.
- Never place financial rates in a technical document.
