Is there such a system for managing applications and clients?

Question

CRM

Good afternoon!
Tell me, plz, are there ready-made systems for the following task:
There is a company that, relatively speaking, has three products (paint a wall, install an air conditioner, clean the air conditioner).
There are incoming applications for these products. Through mail, through a form from the site, through viber / whatsapp, or added by yourself.
You need to:
- create a list of products
- based on the request, add an entity - a new client (indicating the source of the request)
- create a task: the implementation of a specific product for a given client within a given timeframe.
- assign this task to a specific executor in the system
- receive notifications / reminders about the need to complete the task
- view statistics by tasks, by deadlines (completed or not)
- it is convenient to work with tasks / clients through a mobile application and through the site
Is there something already ready for these requirements?
As far as I understand, in conventional task management systems there are basic entities: project, task, performer.
I need: a product, a task, a performer, a client.
