We've stated that a planner's work is valuable, and a planner who is brought in at the month-out mark to assess, organize or fix anything you've completed up to that point, and then handle the flurry of tasks and activity inherent to the last month takes on a whopping amount of work. A large amount of time will be spent on the catching up phase and coordinating communications with other busy vendors on your behalf. If your plans aren't in good order at the month-before point, you're essentially launching your wedding planner in crisis mode.
Planners setting prices for their packages need to prepare for an entire year's worth of planning to be done in this one month, so their price configurations account for much time spent. Time is money. Thus the price point of month-of wedding planning.
Remember, a good wedding planner knows about and handles a collection of details that you're likely not even aware of, all of which are essential to the wedding day's success. If one of these little details is handled wrong, you and all of your guests will likely see and feel it on the wedding day. A wedding planner has a tremendous amount of responsibility and pressure to get everything just right, and on top of that, keep everyone performing at their best (including you.) With the number of occupations seemingly included in the job of a wedding planner, it's no wonder ' and no question ' why they cost as much as they do.
