"someone told me"

If that person wasn't your CPA/tax accountant, leave the bills in Accounts Payable (A/P).  The problem with moving a bill out of A/P and into a long-term liability account, is that you can no longer use the Pay Bills function.  That only works for bills in A/P.  Again, long-term liabilities are only for debts that are not due in the next 12 months - 5 year loan payable balances, mortgages, etc.
