From the Planning Toolbar within a wedding, select BUDGET. Once you’re on the budget page for the event, click on your current Budget total shown, located on the top left of your screen. From here, a secondary budget worksheet will pop up, where you can change your total budget amount.
Once you’ve changed your budget, if your category budgets are enabled, you can either manually distribute the funds where you see fit, or you can have Aisle Planner automatically divvy up the extra funds between each category. To do this, you’ll want to “LOCK” the categories that are already set and won’t be changing, then click “Auto-Adjust Category Budgets” to the top right of this pop up screen.
