Automatic billing with client discount incorrect

[tamalita]

I have been having problems with one single client and I can't for the life of me seem to get it right.

 

I have this client placed in a group with a discount.

 

This client has a billable item (monthly).

 

Everytime this invoice is sent out, the wrong things are added into the invoice so that the final total due is incorrect. There have been many manifestations/iterations/combinations.

 

What typically happens is the same thing that happened this month:

The billable item is added twice

The client discount is added

The total amount due is correctly calculated but is not the actual amount due

There is only one billable item in her account

 

I am not sure why the second billable item is being added

 

When a client signs up using monthly payments, as opposed to a single payment, is there a need for me to manually add in a billable item or is the monthly payment automatically generated?

 

I think I had a problem with this when the client first signed up for monthly payments - no invoices were being sent out to the client.
