CRM suggestion for sales process via funnels and woocomerce

Hey r/CRM, I need a suggestion for my sales process, it goes something like this.

It's split into two, A and B.

A: the Funnel

1. Lead goes through a Funnel and enters their number and name.

2. The agent calls the lead to confirm the order and get the address to ship to.

3. The order goes through a software for inventory and order management (for example Zoho inventory)

4. The lead is converted to a contact to be called again at a later date

B: Woocomerce

1. Lead buys a product on the web store.

2. The order goes through a software for inventory and order management (for example Zoho inventory)

3. The contact is saved for calling at a later date

The main issue i have is that the process needs to be simple for the agents and all the leads and contacts need to be at the same place, in one CRM application.
