How can i change an expense type under Expense Transactions ? We have expenses showing up as "cheques" but do not use cheques or cash.

Hey stacyi1,

It's awesome that you're looking to further organize your books using transaction types! QuickBooks Online uses these types to figure out how transactions should affect your books. To maintain consistency in how things are recorded, transaction types can't be changed unless you manually recreate the transaction. Cheques and Expenses can be used somewhat interchangeably for things paid on the spot, so there's no problem as long as the correct accounts are affected. Here are a few basic guidelines about these two transaction types: 

• If you need to print a cheque, record an expense as a Cheque, instead of an Expense.
• If you paid something via credit card, use Expense.
• If you paid something via EFT, you should still use Cheque or Expense. You can enter EFT in cheque number field.
