Ok, so thats not the way I thought this could be work.
I need this: when I pay vendors I want to create an invoice for them. Who sell in my legal- fiscal case are vendors, that sell their products to buyers. I just do an intermediation between them and earn a fee.
So my role, with hikamarket is to manage money for the vendor.
Now, vendor pay this service with a fee. So, when I "pay" vendors I must submit an invoice to them, because in reality they are paying to me. It is like if I give 100% of money to vendor and then he pay me back my fee.
So, in reality, my customer is the vendor and not the buyer, and I must provide an invoice to vendors.
That s why I thought I could solve this problem using that invoice system but thats not possible, first 'cause I would store automatically an addess and VAT for vendor and also, most important, because I need to report in the invoice the exact value that vendor "pay" to me with the fee. So, if he receive 70% on every sales, and I receive 30%, I must provide to him an invoice with a voice of 30%.
Also, this voice should not be the product item voice but something like "intermediation for selling product xx with order yyy".
Hope I explaned what I need and really hope this could be done. Otherway I should do it manually for every "paymen".
Thanks
