Why the sales budget at the starting point for a master budget?

The sales budget serves as the starting point for a master budget because it estimates the expected sales revenue, which directly influences all other components of the budget. By projecting sales, a company can determine production levels, inventory needs, and resource allocation, ensuring that financial planning aligns with anticipated market demand. This foundational budget helps in setting realistic financial goals and ensuring that all departments operate cohesively towards achieving the overall business objectives.
