Again, I didn't select Beeline, our clients did. But in comparing these products from a user perspective, I would rank Beeline about on par with the rest. IQNavigator and Fieldglass are probably the best ones, and Covendis is by far the worst. The rest are fairly similar, and all have many of the same issues. Most companies don't take the time (or the VMS doesn't allow them) to simplify the software for use. There are always a ton of unnecessary and unused features that are required to fill out, or require clicking through, and it honestly wastes a ton of time. I will say, though, that I have used Fieldglass for more than one client, and it is the easiest, every time.
I have utilized IQNavigator, which is not appealing to the eye, does not provide too many options and is slower to take effect. Beeline, although it has room for improvement, is leaps and bounds better than the IQNavigator product.
I was not an active use of Fieldglass, but based on what I saw of its interface and functionality, the candidate and requisition management functions of Beeline were far superior - easier to use, and easier to make sense of the information it was being used for.
Beeline VMS is a vendor management system for managing a contingent workforce. It was recently acquired by Chicago-based private equity firm GTCR, which also owns another workforce management company, IQNavigator, with which Beeline will be combined.
