Receipt of Bid is a document that is issued to acknowledge the receipt of a bid, which can be an offer to buy goods or services. It is also called a Bid Acceptance Letter and is issued by the seller or a bidder. The receipt of the bid is a confirmation that the offer has been received and accepted. There are two types of Receipt of Bid: an unconditional receipt and a conditional receipt. An unconditional receipt is issued when the bid is accepted without any conditions, while a conditional receipt is issued when the bid is accepted with certain conditions. The Receipt of Bid should include the date and time of the bid, the name of the bidder, the amount of the bid, and any other relevant information. The Receipt of Bid also serves as a confirmation that the offer was received and accepted by both parties.
