A tender is an invitation to bid on a project or accept a formal offer such as a takeover bid. There are different types of tenders including open/public tenders and closed/invited tenders. The tendering process involves announcing the tender, submitting bids, opening bids, evaluating bids, selecting a winner, and issuing a work order. Key sections of a tender document include conditions for participation, quality standards, specifications, contract terms and conditions, and bid submission details. Tenders are used by governments and organizations to ensure transparency and fair competition in procuring projects and services.
