Accounting: Account Summary, view a list of all active accounts in the system

1. Go to 'Reports>Accouting>Account summary'.

2. Here you will see a list of all account numbers that are active at the moment.

'Account' column shows the account number

'Description' shows what the number refers to.

It will look like this: "AccountType : Type" if the same account number is used more than one time both account types and type will show in the description. 

For example "Products: Room service; Services: Room service".

In this example the Room service account is added both as a Product account and as a Service account.

All accounts can be configured or changed in 'Drop Down Lists', read more here.
