The interface is easy to use at first glance so I did not have any issues getting it up & running or using it in my business. There are some features missing (like advanced search/search by date range) but these could be added quickly as they're very simple fixes! If you want ease of integration into your existing website make sure this works well wtih WordPress. We were able to set up calendar events easily from our own site which was one less thing we needed another app like Google Calendar for. It is easy to set up and use. The customer service is great as well! I wish it was easier to add new clients and submittals but it's getting better every week. This is a great tool for my business. I love how easy it is to keep track of all appointments, clients, and payments. I can also easily share these files with other staff members. I am able to save time by not having to manually enter information into spreadsheets.
