Budget planning is a crucial step in organising any event, ensuring that all aspects are covered without overspending. Begin by establishing a clear overall budget, then break it down into categories such as venue, catering, entertainment, décor, and miscellaneous expenses. Allocate funds based on priorities, allowing flexibility for unexpected costs. Keep detailed records and regularly update the budget to track expenditures. Effective budget planning not only helps control costs but also enables seamless coordination, resulting in a successful and memorable event.
