Hi guys I need some info from you. My first cpc facebook ads campaign just finished yesterday.The campaign ran for 3 days spending 8.93$ which is lower than my max budget 15$. Before the campaign launched,I submitted my paypal info to FB.But till now I've not been charged forthe 8.93$ in my Paypal account. When will FB charge it ? In the end of the month? And how does FB charge me? Directly from my PP account? Or I'll receive a invoice and then pay them manually?
