Breh, I'm a former auditor. If I see this money you paying yourself coming in from your "business", I'm going to want to see:
a) billable hours
b) services rendered
c) parties services rendered to
d) invoices
e) receipts
And I'm backtracking credits to your accounts to the corresponding invoices for services rendered and I'm verifying the third parties whom you performed services for. If I don't see any of that, I know there is some fukkery.
Same with the receipts. Backtracking debits from your account to the corresponding receipts for items you paid for, verifying those items exist, and verifying the third party with whom you entered into the transaction with.
If you gonna launder money you better be thorough with it. And the endgame shouldn't be simply to buy a car.
