sql join query

[Barry Olly]

We have the three tables below and for each customer, we need the
following information;

Result expected:

Month | Sales total | Payment | Oustanding

Jan | 1200.99 | 200.99 | 1000
Feb | 0.00 | 1000.00 | 0
Can anyone help out with the sql query to generate this.

Thanks

Barry
