For each account, this report displays the account balance at the beginning of a date range, the total debits and credits within the date range, the net activity, and the balance at the end of the date range for those transactions assigned to the selected category.
Usually the summary report, rather than the longer detail report, is adequate. The summary report gives you one line (beginning balance, total debits, total credits, net activity, and ending balance) per account. If needed, you can generate a Category Trial Balance [Detail] report for the month. This will generate a line for every transaction (it can be a huge print-out) entered during the month.
