In short: A tender is signed by a person, never by a firm, so every bid needs a document proving that the person who signed was allowed to. A power of attorney for tender is that document. Under the Powers-of-Attorney Act, 1882, it is any instrument empowering a named person to act for and in the name of the person who executed it, and Section 2 makes what that person signs as effective in law as if the owner had signed it himself. A proprietor signing his own bids rarely needs one. A partnership, an LLP or a company does. Get it stamped as your state requires, keep the name on it identical to the name on the signing certificate, and replace it the day the signatory leaves.

What a power of attorney for tender actually does

The bid you upload is an offer. Somebody has to make that offer, and departments will not take “the firm signed it” as an answer, because a firm cannot hold a pen or a signing key. What they want is a chain: this business authorised this individual, and this individual signed.

The Powers-of-Attorney Act, 1882 is short, and the two sections that matter to a contractor are worth reading in plain terms. Section 1A defines a power of attorney as any instrument empowering a specified person to act for and in the name of the person executing it. Section 2 then says the holder may execute a document in his own name and with his own signature, and that what he does is as effectual in law as if it had been done in the name and with the signature of the person who gave him the power.

That second point is the one owners get wrong. The authorised person signs as himself. He does not sign your name. A bid signed “for M/s Sharma Earthmovers” by the person named in the instrument is correctly signed; a bid where a manager has signed the proprietor’s name is a forgery risk dressed up as convenience.

The Indian Contract Act, 1872 supplies the rest of the machinery. Section 182 defines an agent as a person employed to do an act for another or to represent another in dealings with a third person. Section 185 says no consideration is necessary to create an agency, so you do not have to pay your signatory anything extra for the authority to be good. Section 188 gives an agent authorised to do an act the authority to do every lawful thing necessary to do it, which is why a properly worded bidding authority also carries the smaller acts around the bid.

Section 226 closes the loop: contracts entered into through an agent are enforced in the same manner, and have the same legal consequences, as if you had made them yourself. The tender you win on your signatory’s signature is your contract, with your liability.

Which authority document fits your business

The right instrument depends on how the business is constituted, and this is where most small contractors upload the wrong thing.

How your firm is set up What normally authorises the signatory Power of attorney usually needed?
Proprietorship, proprietor signs The proprietor is the firm; a self-declaration naming him is often asked for No
Proprietorship, somebody else signs Power of attorney from the proprietor Yes
Partnership firm Authority letter signed by all partners, or a power of attorney executed by the firm Usually yes
LLP Resolution of the designated partners, plus a power of attorney where asked Often
Private limited company Board resolution authorising the person, plus a power of attorney where asked Often, alongside

A board resolution and a power of attorney are not substitutes for one another, even though bid documents talk about them in the same breath. The resolution is the company deciding something internally. The power of attorney is what you hand to an outsider to prove the decision reaches them. Section 1A is wide enough that a resolution drafted as a grant of authority can serve as both, but when the tender lists the two separately, upload the two separately and stop trying to save a page.

What the document has to say to get through technical evaluation

Evaluators are not reading your instrument for elegance. They are checking five things, and a document missing any one of them gives them a clean reason to set your bid aside before the price envelope is opened.

The full name and designation of the person authorised. Not “our authorised representative”. A name, matched to the identity document you upload with it.

The acts covered. Signing and submitting the bid is the minimum. A workable instrument also covers signing the covering letter and declarations, attending the pre-bid meeting and negotiations, signing the agreement if you win, and receiving correspondence. Section 188 helps here, but it works from what you wrote down, so write the list.

Who executed it, and in what capacity. The proprietor, all the partners, the designated partners, or the company acting on a resolution whose date and number you quote.

The date. It has to predate the bid. An instrument executed after the submission date is worth nothing for that bid, and departments do check.

The specimen signature of the holder, attested, so the evaluator can match it against what came in.

Section 227 of the Contract Act is the reason this precision pays. Where an agent does more than he was authorised to do, and the authorised part can be separated from the unauthorised part, only the authorised part binds the principal. A narrow instrument does not protect you; it leaves you arguing later about which half of what your signatory did actually counts.

Stamping, notarisation and the dates that get bids rejected

Stamp duty on a power of attorney is a state subject, charged under the Stamp Act applying where the instrument is executed, and neither the amount nor the required form is uniform across India. That is why you will not find a single figure worth quoting, and why an owner working across state borders should not reuse an instrument stamped elsewhere without checking.

Take the requirement from two places: the bid document, which will usually say whether it wants the instrument notarised, registered, or merely on stamp paper of a stated value, and the stamp rules of the state where you are executing it. Do this when you decide to bid, not on the last afternoon. Notarisation takes a day you will not have.

Section 4 of the Powers-of-Attorney Act offers a facility worth knowing about if you bid often. An instrument creating a power of attorney, its execution verified by affidavit or other sufficient evidence, may be deposited in the High Court or District Court within whose limits it lies, and a certified copy of a deposited instrument is, without further proof, sufficient evidence of its contents and of the deposit. For a contractor who is asked for the same proof a dozen times a year, a deposited instrument and certified copies beat passing the original around.

The signing certificate and the authority have to name the same person

Bids are signed and encrypted online with a digital signature certificate issued to a named individual, and once that certificate is mapped to a portal account it cannot be moved to another account. The process of bidding for government construction tenders assumes those two names line up, and the commonest failure in the whole area is that they do not.

It happens like this. The owner takes the certificate in his own name because he opened the portal account. Work grows, and a nephew or a manager starts handling submissions. The power of attorney gets drafted in the manager’s name because he is the one doing the work. Now the bid is signed by a certificate that says “owner” and accompanied by an instrument that says “manager”, and the evaluator has an inconsistency on the record.

Fix it in whichever direction suits the way you actually work. Either keep signing yourself and drop the instrument, or get the certificate in the signatory’s name and authorise him properly. What does not work is leaving the two documents pointing at different people and hoping nobody reads carefully. The same discipline applies on the GeM portal registration a contractor completes before bidding there.

If you are still assembling the paperwork behind a first bid, the Udyam registration a contractor needs and the solvency certificate a tender asks for sit in the same file and have their own lead times. Machine-hire work worth bidding for is listed among the current tenders and equipment opportunities, and it is worth having the authority document ready before one of them closes.

When the authority ends, and why that matters after you win

An authority is not permanent, and Section 201 of the Contract Act sets out how it ends: the principal revokes it, the agent renounces it, the business of the agency is completed, or either party dies, becomes of unsound mind, or is adjudicated insolvent.

For a contractor the live risk is the middle of a job. Your signatory resigns eight months into a two-year contract, and he is the name on the agreement, on the correspondence and on the portal mapping. Three things then need doing, in this order: write to the department recording the change, execute a fresh instrument in the new signatory’s name, and get the portal account’s certificate mapping changed.

Section 3 of the Powers-of-Attorney Act protects the outsider in the gap. A person who makes a payment or does an act in good faith under a power of attorney is not liable merely because the power had been revoked before he acted, if he did not know. That protection runs in the department’s favour, not yours. It is a reason to give notice quickly, not a cushion for taking your time.

One more point that catches owners who think the authorised signatory carries the risk. Section 230 of the Contract Act says that, absent a contract to the contrary, an agent cannot personally enforce contracts entered into on behalf of his principal, nor is he personally bound by them. Your manager signing the tender does not make your manager liable on the contract. The obligation, the earnest money at stake and the performance risk all stay with the firm.

Before you upload the next bid

Run the same five checks every time, because the documents drift as the business changes.

Read the bid document’s own clause on authorisation rather than working from the last tender, since departments differ on whether they want a general or a bid-specific instrument. Check that the name on the instrument matches the name on the signing certificate. Check the execution date sits before the submission date. Check the stamping matches the state you executed it in. And check that the person named still works for you, which sounds obvious until it is the thing that failed.

Questions on the authorisation clause itself belong at the pre-bid meeting, where the answer is recorded and binds the department. Raising it afterwards gets you nothing, and the integrity pact a tender requires is signed by the same authorised person, so an error in the instrument spreads across the whole submission. If eligibility rather than paperwork is what keeps stopping you, the bid capacity formula is the number to work on next.

The bottom line

A power of attorney for tender is a cheap document that protects an expensive bid. The law behind it is settled and short: the Powers-of-Attorney Act, 1882 makes the holder’s signature as good as yours, and the agency chapter of the Indian Contract Act, 1872 decides how far his authority runs and when it ends. What loses bids is never the law. It is a date out of order, a name that does not match the signing certificate, or stamping done for the wrong state.

Get the instrument drafted once, properly, and keep certified copies. Then put your effort where it earns money, which is finding work worth bidding for. Browse the live tenders and equipment opportunities, and if you are still sizing the machine behind the bid, compare excavator models and prices before you commit to a rate.

This is general information for machine owners and contractors, not legal advice, and stamp duty and authorisation requirements differ by state and by department. Read the authorisation clause in the tender document itself and confirm the current requirement with the issuing department, your certifying agency or your own advisor before you submit. Rates, schemes, specifications and prices change — confirm current terms with the OEM, dealer, bank or insurer before deciding.
