Advice about binance P2P and banks

Hi, I am doing p2p in some centralized platforms (Binance), I lately began to maneuver high volumes comparable to 60Okay USD each 2-3 days. The began to ask where the cash is coming from, I have no replied since banks in my country will not be crypto friendly, some suppliers of crypto that I have, (additionally they do p2p) started telling me "You'll want to create a enterprise account and start justify the transactions of selling/shopping for crypto by creating invoices for providers", my query is, will this no carry a authorized situation? I mean i do know just isn't illegal lying to a financial institution, but if they do some type of due diligence that may give me some troubles sooner or later?
