This software was invaluable when I was planning my wedding. It enabled me to keep my guest list, responses, and to do list in order. On top of that it even made my seating charts a snap - especially when we had to make a bunch of last minute changes. The software comes with a free 30 day trial so it is worth trying out to get your initial planning setup, but if you are serious about staying organized this is a great tool. I would personally push any other wedding software on this site because I didn’t find anything else worth my time. If you do decide to check it out please comment on he site and let us know what you thought. More info is available here or you can download or buy iDo below.
