What in-house csrp system might be considered for a small food manufacturing company?

Question

ERP

All popular systems are crm and are aimed at sales.
The company has two clients and does not need to develop sales. You need to control the execution of tasks, communication within the company, and other goodies: for example, a knowledge base, a chain of accounts reconciliation, etc.
