Is there a task scheduler for the client?

Question

Project management

Good afternoon, I know about wrike, jira, trello and so on.
But I'm interested in a tool that will be simple for a regular client, who could make a list of tasks, edits, and so on, then just mark what has been done or add a comment.
It is necessary that the client can quickly join the project, without any complicated registrations and project creation.
Is there something similar?

Answer 1

A simple option + is Trello
A more expensive but better option is Planfix
Trello can be integrated with telegram quite simply, and the customer will be able to receive notifications.

Answer 2

Client vsmysle customer?
or a client in the sense of a visitor, user
For the latter, some kind of help desk with ticket management is suitable, something like ladesk,
but for the first trello, I guess it’s best to
have something else like a messenger , I read about it, I didn’t try it, I don’t know for sure
