What is a Performance Bank Guarantee (PBG)?
A PBG is a bank's promise to pay the buyer if the contractor fails to perform. How it works in Indian contracts, and how it differs from EMD.
A Performance Bank Guarantee (PBG) is issued by the contractor's bank in the buyer's favour. If the contractor fails to perform, the buyer can invoke it and the bank pays — regardless of any dispute between the two parties.
How it works in India
The tender or contract states the percentage of contract value and the validity period, which normally runs to the end of the defect liability or warranty period rather than to completion.
The contractor's bank issues the guarantee against margin money or an existing credit limit, so a PBG consumes real working capital for its whole life. That cost is part of what a bidder prices in.
Most PBGs in Indian public contracts are unconditional — the bank pays on demand, without requiring the buyer to prove default first. That is exactly what makes them worth having, and exactly why contractors negotiate hard on the wording.
PBG vs EMD
EMD guarantees the bid; the PBG guarantees the contract. EMD is usually released when the PBG is furnished, so the two are sequential rather than concurrent.
What people get wrong
Letting the validity lapse. An expired PBG cannot be invoked. Extensions have to be tracked against project delays, not against the original programme.
Ignoring the working-capital cost when pricing. A 10% PBG held for three years is a real financing cost, not a formality.
Assuming invocation is easy. It is contractually straightforward and commercially severe — invoking a PBG usually ends the relationship and often triggers litigation.
On Bidancer
Bidancer does not issue or hold guarantees; contract security stays between the two businesses. What the platform contributes is what comes before it — verified identities, comparable bids and a recorded award, so the contract is signed with a counterparty you can actually assess.
