Lead stages in Odoo represent the different steps a lead or opportunity goes through in the sales process. They help sales teams track progress, stay organized, and focus on the right tasks at the right time. For example, you can start with a new lead, then move it to contacted, qualified, proposal, and finally won or lost. Each stage gives a clear view of where the lead stands and what action is needed next. This makes it easier to manage the sales pipeline, improve follow-ups, and close deals more effectively.
