Order creation and first payment amount

[osckar]

Hi:

 

when creating a new order for a client, then you can modify the hosting account and domain details, but when setting the price how can I add tax? Because when a client view his active services on client area it say:

 

example:

First payment amount: 10.00 when the client already paid 15 (10 +tax)

 

1.- do I need to set the price with tax included?

 

2.- If I selected not to create an invoice for that order, when due, will the system create an invoice for the new payment period of that order?

 

Thanks!
