GST Paid doesn't match Balance Sheet

Hi SMM

So, in theory, assuming all transactions were recorded as Spend Money transactions (which record the payment at the time of recording the transaction) you could run the General Ledger Detail report for that particular account. You could compare this with the GST [Detail - Cash] for the same period and identify transactions that are not recorded in the General Ledger Detail report that are in the GST Detail report or vice versa.

Although, it should be noted that you are comparing an accrual basis and a cash basis reports so you are comparing two different accounting method based report. As such other considerations do need to be taken into account for example transactions recorded outside of the period that are impacting the account balance.
