For starters, the web interface is not intuitive. I have difficulty finding any of my time sheets or expense reports. There are too many filters to check, and even when I try to go for simple by setting everything to "All", I can't actually see "All" of my items. It is not designed to fit onto a regular laptop or computer screen. The UI is so wide that I have to scroll horizontally, which cannot be done easily using a mouse. This requires the user to go out of their way to grab the scroll bar and move it. While this might be ok for a user with a touch interface, such as a Surface, the majority of business users aren't provided those in their business environments. In addition, the reports are difficult to read and I don't have any confidence in their accuracy. Also I cannot be made a direct approver of the specific tasks on my project, which is a sub-project as part of a larger effort. Therefore I have no visibility into my resource's hours, and have to ask them to email me their hours each week in addition to filling in their timesheets, when this should be relatively easy to do in any timesheet application. Doing my weekly time and expenses has become a tedious and dreaded activity that consumes so much more of my time than it should.
Then, there's the mobile app. For the most part it works ok, and it's much simpler than the web app which makes me tend to prefer it. However, whenever I try to type a number amount, such as a 4, the app replaces the value with a 9. In addition, it doesn't allow me to use my own keyboard - it replaces it with an app-specific keyboard that doesn't have punctuation, so when I try to follow our company attachment naming convention (which includes an underscore) I have to type it in a note app and copy and paste it into the OpenAir app.
Lastly, I have attempted to contact OpenAir and/or NetSuite to discuss these issues I've been having. Not only can I not get in contact with anyone, there is no easy or intuitive way to reach the company.
All around, OpenAir is a really poor service. There are better products on the market and I would not advise anyone to waste their money on this product.
