Patreon payment? ENG and ITA

Hello everyone! As I told you before, a friend of mine has just started using patreon to promote her artwork. The problem is, now that she has been paid by some promoters... How can she withdraw the money she got?
Let me be clear on this... She is italian, just like me, so the terms of agreement are quite confusing to understand, as there are different rules in Italy for this stuff. It's the first time we've ever dealt with Patreon... So what should she do? Thanks in advance!

E perciò ora mi rivolgo ai compaesani. Come si fa a ricevere i pagamenti di Patreon? Né io né la mia amica sappiamo come venire a capo delle regole della piattaforma... Perciò se ci poteste suggerire cosa fare, ve ne saremmo infinitamente grate. È la prima volta che abbiamo a che fare con Patreon, non abbiamo la minima idea di come comportarci...
