DBA's fine.
Any other business/organization, we require a full deposit into the account with no cash back, and then a cash withdrawal, or cash a check payable to them and drawn on the account.
This has been the common practice at the three financials I have worked for over the last 14 years.
The owner of the money is not the individual presenting the deposit, it is the business/organization. Two words come to mind...tax evasion...something I do not want my bankers to aid our business customers in.
