Bank guarantees in tenders: bid security, performance, advance

Every industrial tender asks for money you do not yet owe: a bid security with the offer, a performance guarantee after the award, sometimes an advance guarantee before the first rupee moves. These instruments run through your bank, they block your credit limits and they have formats the buyer will not negotiate. Understanding the three guarantee types — and their real cost — is what separates a vendor who plans cash flow from one who discovers it.

The three guarantees in one tender cycle

The bid security, still often called EMD even when given as a guarantee, accompanies your offer and protects the buyer against a bidder who withdraws or refuses to sign. The performance bank guarantee, typically five to ten percent of the contract value as the NIT states, secures execution and usually stays alive through the defect liability period. The advance guarantee covers any mobilization advance the buyer pays, and it reduces as the advance is recovered from running bills.

Each instrument has its own life. The bid security dies when the contract is signed or the validity lapses. The performance guarantee outlives dispatch and commissioning, sometimes by twelve to eighteen months. The advance guarantee shrinks on paper but only if you send the recovery statements to your bank — a step vendors routinely forget.

What a guarantee actually costs you

A bank guarantee is not free money blocked in a vault; it consumes your working capital limits. Banks charge a commission, commonly in the range of one to two percent per annum on the guaranteed amount, plus they may ask for margin money in fixed deposits or take it out of your cash credit headroom. For a performance guarantee of ten percent on a two-crore order held for twenty-four months, the direct commission alone runs into lakhs, and the limit blockage costs more if your margins depend on that credit line.

Format discipline: the clause nobody reads twice

Buyers attach the guarantee format to the tender, and banks issue exactly that text. A deviation — a changed claim period, a missing clause number, the wrong beneficiary designation — gets the guarantee rejected, and on bid securities that rejection can disqualify the offer. Before your bank issues anything, send the draft to the buyer's format check if the tender allows it, and confirm the issuing bank branch is acceptable: some buyers insist on scheduled banks, some on branches in India, and GeM-linked tenders have their own verification routine.

• Use the tender's own format, verbatim, including claim period wording.
• Check the beneficiary name against the contract-awarding entity, not the project site.
• Diary every expiry date with a reminder sixty days ahead.
• Return the original guarantee paper for cancellation once discharged.

Extension requests and the claim risk

One more cost line hides in renewals: banks re-price the commission when a guarantee is extended, and an extension after your credit rating slipped costs more than the original issue. Vendors with multi-year defect liability periods should negotiate a reducing guarantee value — many contracts allow the performance guarantee to step down after provisional acceptance, which frees limits exactly when the next tender needs them.

The dangerous moment in a guarantee's life is the extension request. When a contract runs long, the buyer asks to extend the performance guarantee, and the standard wording — "extend or pay" — means the bank must either extend or honour the claim immediately. A vendor who ignores the letter loses the guaranteed amount by default. The correct move is to extend early and negotiate the defect liability end date in the same letter, so the guarantee does not drift into an open-ended life.

When guarantees go wrong: real failure modes

The first failure mode is the forgotten advance guarantee that stays alive for years after the advance was recovered, quietly eating commission and limits. The second is the expired performance guarantee on a contract still in defect liability: the buyer can demand reinstatement, and the reissue now costs fresh margin money at worse terms. The third is the guarantee issued by a bank the beneficiary does not accept, discovered at the worst possible moment — during contract signing, with the delivery clock already running.

None of this is exotic banking. It is a register, a calendar and the habit of closing instruments that have done their job. The vendors who lose money on guarantees are almost never cheated; they simply stop watching.
