Admin is a bit of a challeng in the upfront set up and is a heavy lift. Lots of planning and designing required, but payoff is worth it once fully set up, it becomes very easy. Adjusting and modifying after isn't difficult, but due to the nature of how built out everything is, it can be challenging.
I would not necessarily recommend going overboard and all out on the guided selling piece for a newer company still "figuring things out" as a lot of adjustments will be necessary.
Stick with the basics and it's a super easy to use tool. Review collected by and hosted on G2.com.
