Technically, it’s not the same. A refinancing by definition is taking one existing loan debt and redoing it, to get a lower interest rate.
A business debt consolidation takes a number of loans and combines them into one debt. However, it is possible when doing a refi of existing debt to add other existing debts to the new obligation. In fact, a lender may like that. A lender has a choice – get your money plus interest from one loan, or get your money plus interest from a number of loans (that other lenders are currently collecting).
