Help with Mysql query?

I have two tables, a Sales, and Other Subscriptions_sales, the sales of the clients are saved with their total value and everything is on credit in the day several sales can be made to a client as no, the client can pay to the total balance you have several times in the day as you may not.

With the following fields a little summarized

TABLA VENTAS
Fecha
Cliente
Valor_Total

TABLA ABONOS_VENTA
Fecha
Cliente
Valor_debe
Valor_Abono
Nuevo_Saldo

What I want to do is a query that brings me grouped by day the total value of the sale made to the client and the total value that I paid on the day, as I said you may buy something or not, or you may pay the debt that day or not.

I want to bring that data in a single row grouped by day in a range of dates

Let it out like this

FECHA | CLIENTE | VALOR_VENTA | VALOR_ABONADO
10-10-2017  ANDRES  $10.000       $5.000   
11-10-2017  ANDRES  $0                 $5.000   
12-10-2017  ANDRES  $100.000     $0   
13-10-2017  ANDRES  $0                  $50.000   
14-10-2017  ANDRES  $10.000        $5.000  

Something like that is what I want to do, but I do not give how, I blocked that there may be records of that day in one table and not in the other and vice versa. The fields of the tables are not only those, I just try to illustrate a bit so as not to entangle more the problem that I have, I thank you for leaving queries that you think can help me.

See more fields and other tables, the above is an illustration
