Advance Payment

Advance payment is an amount paid by the contracting authority to the winning supplier before substantive work begins, intended to cover the initial mobilisation costs such as equipment purchase, staff deployment, and site preparation that the supplier would otherwise have to finance from its own working capital.

What is Advance Payment?

In MDB-financed contracts and most international public procurement frameworks, advance payment is a contractual entitlement rather than a discretionary favour. It is typically set at between 10 and 30 percent of the contract price and is expressly permitted under standard contract forms such as FIDIC and World Bank Standard Bidding Documents. Critically, it is only released against an advance-payment-guarantee of equivalent value issued by an acceptable bank, which gives the employer security if the supplier defaults before the advance is recovered. The advance is then recouped progressively through deductions from progress-payment certificates at a stated percentage until it is fully recovered, usually before the final quarter of the contract.

The purpose is to reduce the cost of financing large works or supply contracts for suppliers who could not otherwise mobilise in time, which in turn encourages competitive bidding from capable firms that lack deep cash reserves.

Why Advance Payment matters for bidders

Advance payment reduces the working capital burden at the riskiest point of a contract, but securing it requires providing a compliant bank guarantee promptly after award. Delays in furnishing the guarantee delay the payment and can affect your mobilisation schedule. Read the special conditions of contract carefully: the guarantee format, the repayment percentage, and the bank eligibility criteria differ by contract. If a solicitation offers no advance payment, model the additional finance cost in your financial-proposal before pricing, since carrying mobilisation costs internally has a real price.

FAQ

How is advance payment recovered?

The employer deducts a fixed percentage from each progress-payment certificate until the full advance is repaid, so the recovery schedule is known from the outset.

What happens to the advance payment guarantee as the advance is recovered?

Most contracts allow the guarantee amount to be reduced proportionally as deductions are made, lowering the supplier's bank exposure over the life of the contract.

Can the employer call the advance payment guarantee?

Yes. If the supplier fails to perform or repay the advance through contract execution, the employer can call the guarantee to recover the outstanding balance from the issuing bank.
