What is an analogue of espocrm or a warehouse module for it?

Question

CRM

Good evening, we use espocrm.
All the functionality suits, but the warehouse is very lacking (bring in components and then apply them to transactions).
I don't want to use 2 separate scripts.
Is there a warehouse module for espocrm? A cursory search on the Internet did not give any results ...
Or maybe someone will advise a free analogue of crm, which is installed on your server?
Ps: It would also be nice to have a plugin for woocommerce or WordPress...
