How can I manage advance payments??
Hi I'm getting trouble when trying to make an advance payment in OpenERP, I just can't understand how can I do it.
Usually my clients give an advace payment of the service they are hiring, but the invoice it's validated at the end because sometimes there are some costs that can't be considered at the beginning of the quotation.
How can I solve the problem or how can I make a payment with a quotation??
Thanks in advance
P.S. This also is a problem with Suppliers Invoice but that is not such a big problem as customers
