Double Entry Module questions

Hey! I am very interested in the Double Entry app, I am not a bookkeeper / accountant :(, but I have some questions about the features, I hope you can help me.

First, I want to have Balance with my clients, they pay me some invoices, but I pay them some things, I wanted to do it with the akaunting core, but I can not, the expenses go to the suppliers and the invoices go to the clients

I want to have a balance only with my clients.

Could the double entry help me with this?

Second, in the customer portal, do the double entry balances show it to the customer? In other words, the customer can check their balance?

Finally, offtopic, there is some way to sent all invoices in bulk, rather than remain in Draft?

Thank you folks, and my greetings to the programmers, amazing job!
