In this chapter, we examined how Odoo generates transactions and how you can use the chart of accounts to look at how those transactions originated. We examined both the Accounts Payable and Accounts Receivable accounts, and looked at how an invoice is posted. There are certainly more advanced Odoo topics, such as bank reconciliation and recurring entries, that are beyond the scope of this book.

In the next chapter, we will look at the Human Resources (HR) application. HR allows us to keep track of employees, the hours they work, and the services they provide. Staff can be assigned to user-defined departments and be designated as managers of other employees. And since your employees will also often be users of the Odoo system, the HR module is tied tightly to the user administration system, which manages access rights and messaging.
