GST can be handled in Oasis in two ways - cash or accrual (or not at all). To switch on/off GST, select Preferences, My Money, Invoice Options and set Field #6 “Üse GST in this practice” to Y or N as required.
If set to Yes, then you need to select Preferences, My Money, GST Rates and Options to configure how GST will be handled in the practice. It can be based on payments received, or on invoices raised. Item codes need to be flagged as GST items, as not all item codes attract a GST (in Australia).
The GST Rates and Options table is as follows:
Tax Rate 10% 10% The The GST rate in force
Round to cents 001 001 The rounding value for calculations
