Hi DaveS,
Someone might chime in and correct me if I'm wrong on this, but QuickBooks handles double-entry accounting for you, meaning every transaction you enter automatically becomes a debit to one or more accounts and a credit to one or more other accounts; in other words the focus here is the business transaction v.s. the debits and credits in the General Ledger. The accounting happens behind the scenes, and it finds the balances for you. Similarly, these same balances appear in Method, so you won't find debits and credits, you will find the balance OF debits and credits, which, if negative, will appear with a preceeding minus symbol. If you look in your Chart of Accounts in QuickBooks, you will find all Method does is pull those same figures.
For reference, I recommend taking a peak in the help section found in your QuickBooks application, as the explainations there are quite helpful in explaining how double entry accounting is handled in QuickBooks.
Regards,
Denis
