Bookkeeping for 3 small businesses

Open to discussions about how to orchestrate this, but I need bookkeeping services for three businesses in United States. I own all three and manage the books myself currently. I use quickbooks desktop and would prefer to continue this. Download bank transactions for checking account and credit card account. categorize transactions, reconcile accounts quarterly. will help with transition as I have been doing myself for many years. produce profit loss, cash flow statements, and balance sheet.
