MOQ, or Minimum Order Quantity, is vital for factory owners for several reasons. 

1. It ensures efficient production by setting a minimum batch size, reducing setup costs per unit. 

2. The stability in order volume encourages consistency in production schedules and resource allocation. 

3. MOQs contribute to profitability by preventing small, unprofitable orders. 

Factory owners rely on MOQs to optimize their operations, maintain profitability, and provide competitive pricing to clients, making it a cornerstone in manufacturing and business planning.
