A list of your income and expenses, no matter how complete, is not a spending plan, but is the information you need to create a spending plan. And, a paycheck_by_paycheck spending plan will help ensure the success of, or at least help prevent the failure of your budget.
Last but not least you have the following categories: food, beverages, cake, decorations, music, photography, video, invitations, transportation, accommodation for the couple's wedding night, attendants' gift and miscellaneous costs. Keep in mind that the cost of the food and beverages is determined by the number of guests you invite to the wedding. When you start making a wedding budget, it's probably best to decide on the amount of money you've set aside and then determine the expenses and the number of people to invite. Otherwise, you will risk overspending.
