You have the option to set up Default Accounts in ConnectNow Accounting by going into Ledger and Payables, Setup, User Options. Select the account against which most of your transactions are applied. If this is not done, the Accounts will be listed in alphabetical order by their description, and the first account listed will be the default.
Note: In Checks, when you select a different account from your default, that new account will become your default account in Checks until you log out and back in or re-select your original default.
Another option is to add a period before the most commonly used Account's description. This will cause that account to list first as special characters come before alpha characters when sorted.
