Hi @Nagah.khaled 

I’m not clear about what you meant by 50% in advance.

you want an advance payment before creating the invoice?

Hi,

Payment terms becomes effective when invoices are posted/printed as instalments and due dates will be calculated based on that.

If the customer has to pay before the invoice is printed. Then you will have to use advance invoice option for this purpose.

However, If the customer needs to pay 50% on the date of the invoice and remaining 50% on a latter date you can create a payment term as follows.

Hope this helps,
