Problem:
I like to create CRM with a toolset is possible.
but I need also to display in back end results from customers can do that with Tooset
i like to make something like project manager
Solution:
Unfortunately, there is no native feature in Toolset to integrate our plugins with a CRM system. The whole scope might need custom programming at many points which you will require to handle. You need to identity first and analyse the scope first by checking what things you can do with Toolset and what will require custom programming or you might need to use different plugin.

But as a suggestion, one possibility you have is to use the wpfusion service: https://wpfusion.com/
Relevant Documentation:
They have several integrations with CRM systems: https://wpfusion.com/documentation/faq/crm-compatibility-table/, and it even has an integration with Toolset, for example: https://wpfusion.com/connect/connect-toolset-types-to-jackpack-crm/
