What do you like best?
Aesthetics! Ease of navigation, intuitiveness, continuous product development. I believe Nifty would catch the ClickUp level someday for sure.
The constant development of the tool is certainly a big plus. I get an e-mail about some new functionality practically every week.
Nifty is a great tool for a freelancer or a small team. Privately, nifty is my basic tool for cooperation with clients and so far it works great.
What do you dislike?
There are no options typical for CRM - budget management, cost estimation, billing hours, and so on. Surely, a little more integration could be needed as well. It's not bad, but it could be better.
Another thing is the application - it is because it is, but somehow it is not useful for anything, or it is simply not very intuitive.
Nifty also has some problems with notifications, because they either pop up double in the browser window and on the desktop, or they don't pop up at all (or I set something wrong myself, I don't know).
Recommendations to others considering the product:
Just give it a try!
What problems are you solving with the product? What benefits have you realized?
I took the management with small clients to a new level, and the aesthetics of the tool only helps in this, causing them very good results and impression.
