Interaction platform designer-customer?

Question

Project management

Tell me, there is a large team of designers and a pool of customers. We need a tool for communication between the designer and the customer, which allows for quick communication between them, a toolkit for reviews, and storage of versions. Roughly speaking, it is necessary, within the framework of some platform, to be able to quickly create many subprojects by assigning an executor there, and providing access to the customer. It is desirable that the interaction takes place in a graphical form (sketches, notes on top of the sketch). Does something similar exist?

Answer 1

The most suitable tool for you is Figma. It has versioning, the ability to add comments, create multiple projects at the same time.
The customer can be given access to view and comment. You can view the work of the designer in real time. You can work simultaneously with several designers in one project at the same time.

Answer 2

See CRM systems. I think they all now know how to attach sketches, notes, etc.
You will be more likely to choose according to your budget.

Answer 3

Realtime board

Answer 4

Invision
Figma
