Client-Company Project share platform

Hello everyone, i´m sorry if i'm asking in the wrong subreddit but since this is related to software development i might find someone who can help me.

So honestly i need some recommendations on platforms that enable a communication between client and company, when i say communication i mean been able to get requests, answer them, file share, ideas that can be commented, ticket system and so on.

Someone recommended me Basecamp and it actually seemed really nice but i was hoping you guys can give me some more to choose from.

​

Appreciate your time, best regards
