Tender documents explained: tender notice (NIT), specifications, BOQ, conditions and annexures

What is a tender document?

A tender document is the full set of documents a buyer publishes to describe what it wants to buy, who may bid, how bids must be prepared and how the contract will work. It is also called the bid document, bidding documents or the tender pack.

In Indian public procurement the tender document is the reference for everything that follows. Evaluators check each bid against it, and the contract is built from it. If a requirement is in the tender document, it counts, even when it sits in an annexure or a datasheet rather than the main specification.

Private buyers and EPC contractors use the same idea under other names: an enquiry, a request for quotation (RFQ) or a request for proposal. Our guide to what an RFP is explains how those formats compare. The structure below follows the Indian central government standard, which many PSUs and state bodies adapt.

Difference between tender notice and tender document

The tender notice, usually called the Notice Inviting Tender (NIT), is the short announcement. The tender document is the complete package the notice points to.

The Department of Expenditure's Manual for Procurement of Goods (opens in a new tab) describes the NIT as the part of the tender document that solicits offers, which gives it legal importance. It says the NIT must carry enough information for a bidder to decide whether to participate and, if so, how to go about it. That is its job: helping you decide whether to look closer.

What a tender document contains, section by section

Paragraph 5.1.3 of the Manual for Procurement of Goods (Second Edition, 2024), which refers to Rule 168 of the General Financial Rules 2017, lists the main sections of a goods tender document. The table follows that order and adds what to check first in each.

Two rules in that structure matter more than they look. The manual says the AITB supersedes the ITB and the SCC supersedes the GCC. A buyer often keeps the standard sections unchanged and puts the real differences in the appendix and the special conditions, so read those first.

The financial bid has a rule of its own. The manual says bidders upload only the downloaded BOQ Excel sheet, filling the relevant fields without altering other portions of the sheet. Our BOQ explainer covers how to read one.

Works and EPC tenders follow the same logic with more weight on drawings and quantities. The Manual for Procurement of Works (opens in a new tab) describes the item rate contract, where contractors quote a rate for each item in the BOQ supplied with the bid documents, as the most common contract type for civil works. Equipment tenders add datasheets that the bidder fills in; see technical datasheets in tenders.

Documents required for government tenders

The phrase 'bid documents' is used two ways: the documents the buyer issues, and the documents you submit. The second list is what most bidders search for. Each tender defines its own list, usually in the ITB or a checklist annexure, but the same items appear again and again.

• Signed bid form or cover letter, in the tender's format.
• EMD or bid security, or proof of exemption where the tender allows one. See EMD in tender.
• Registration documents: GST registration, PAN, and Udyam registration where you claim MSE benefits.
• Experience evidence: purchase orders, work orders and completion or performance certificates for similar work.
• Financial evidence: audited accounts and turnover or net worth certificates from a chartered accountant, in the tender's format.
• Manufacturer's authorization, when you quote goods made by another firm.
• Technical offer: filled datasheets, catalogs, drawings, a quality assurance plan and a technical compliance statement.
• Deviation statement, or a 'no deviation' declaration if the tender asks for one.
• Declarations and the integrity pact, where applicable.
• Financial bid in the format the portal provides.

Missing items are expensive. Paragraph 7.3.1 of the goods manual lists reasons a bid can be treated as unresponsive, including an unsigned bid, missing EMD or unproven exemption, goods from another manufacturer without its authority letter, conditional bids where they are not permitted, and a bid validity shorter than required.

How to read a tender document: a seven-step order

Reading front to back wastes time on sections that only matter if you can bid at all. This order puts the deciding questions first.

1. Read the NIT and note the dates: pre-bid query deadline, pre-bid meeting, submission deadline and bid opening.
2. Check the qualification criteria against documents you already hold. If you cannot qualify, stop here. Our eligibility guide shows how teams check this.
3. Read the schedule of requirements to confirm the scope: items, quantities, delivery points, spares, installation and services.
4. Read the technical specification, datasheets and drawings, and list every standard, test and inspection they name.
5. Read the AITB and SCC for the commercial terms that change the price: liquidated damages, payment terms, performance security, warranty and price variation.
6. List the submission forms and the documents each one needs, with an owner for each.
7. Write down every conflict or unclear point as a pre-bid query before the clarification deadline.

Corrigendum in tender: what changes and how to track it

A corrigendum is a formal amendment to the tender document issued by the buyer before the submission deadline. It can change a date, a specification, a quantity, an eligibility criterion or a form.

The goods manual (paragraph 5.1.5, referring to Rule 173(iii) of GFR 2017) allows the buyer to amend the tender document at any time before the submission date, on its own initiative or in response to a bidder's question. Copies go on the e-publishing portal and the buyer's website. When the change is significant or little time is left, the deadline is to be extended by not less than three days.

Central ministries and their bodies must also publish tender enquiries and corrigenda on the GeM-CPPP portal (opens in a new tab) (paragraph 5.1.4, Rule 159 of GFR 2017). State portals, PSU portals and GeM have their own pages for corrigenda, so check the portal named in the NIT.

• Check for corrigenda when you start, when you price and on the day you submit.
• Keep a log: corrigendum number, date, what changed and which part of your bid it affects.
• Re-read the changed clause in context; a revised datasheet can change a value that the specification refers to elsewhere.
• Treat pre-bid replies the same way. The manual says changes after a pre-bid conference are issued as a corrigendum that forms part of the tender document.

Questions to the buyer follow the dates in the tender. If the tender gives no clarification end date, paragraph 5.2.4 of the goods manual says questions should be raised before seven days of the bid deadline. Bidders can also modify or withdraw a submitted bid up to the deadline; the portal treats the last bid submitted as the valid one (paragraph 5.2.5). The tendering process guide places these steps on a timeline.

Worked example: reading a pump tender (illustrative)

This example is illustrative. It is not a real tender, and the details are simplified. A pump manufacturer downloads a public sector tender for six centrifugal pumps with motors, delivered and commissioned at one site. The pack has an NIT, an ITB, an AITB, the GCC and SCC, a technical specification, a datasheet workbook, a BOQ sheet and twelve forms.

Three of the six answers were outside the main specification. That pattern is common, and it is why reading order and source references matter more than reading speed.

How AI tools help with tender documents, and what people still decide

AI is useful where the work is finding and organizing, not judging. TenderGenie's Document Intelligence analyzes the PDF, DWG, XLS and DOC files in a tender pack, brings out specifications, scope, clauses, obligations and datasheet requirements, and links each finding to the document and page it came from. You can ask a question across the whole workspace, such as which tests apply to the main equipment, and open the source to check the wording.

Earlier in the process, TenderGenie's Tender Sourcing brings notices from government, private, e-procurement and global sources into one relevance-scored list. Coverage of specific portals varies, so confirm the sources your team relies on.

People still decide what matters:

• Engineers interpret specifications and decide whether the offered product meets them.
• Commercial and legal leads read the special conditions and decide which risks are acceptable.
• The bid manager decides which questions to raise with the buyer and checks the final package against the submission instructions.
• Leadership makes the bid or no-bid decision.
