An Invitation to Bid (ITB) is a formal request issued by an organization or government entity inviting suppliers or contractors to submit competitive proposals for a specific project or service. The ITB outlines the project requirements, specifications, and deadlines, ensuring that all bidders have the same information to create fair and comparable bids. Typically used in procurement processes, the ITB aims to promote transparency and competition among bidders. Once the bids are submitted, the organization evaluates them based on predetermined criteria, such as price and quality, before selecting the most suitable contractor to fulfill the project requirements.
