Nutshell discussions

i'm trying to understand the pricing plans for nutshell. is there a free trial or any hidden costs?

we use a couple of different tools for marketing and project management. can i integrate those with nutshell?

i'm thinking about switching CRMs and considering both nutshell and some other options. what are the key factors to weigh when choosing between them?

for anyone who's set up nutshell for a small business, what tips do you have? any must-have features to activate?
