Can I set a 'Starting Balance' for my account?

In Moneydance, this is called the "Initial Balance" of an account. It can be set when creating an account, or can be altered at any time.

Open the register of your account by clicking on it in the left sidebar, and then go to Account --> Edit Account from the Moneydance menu bar.

In the window that appears, one of the fields is for the Initial Balance of the account, which should be set at the value of your account before the first transaction you have entered.
