Using Include GST:
The 'Include GST' feature enables you to ascertain the tax component to append to a GST-exclusive price, yielding both the GST figure and the inclusive final price - essential for accurate quoting, pricing strategies, and customer billing.
Using Exclude GST:
Conversely, 'Exclude GST' permits you to deconstruct a GST-inclusive price, separating the underlying base cost from the GST paid, which is invaluable for expense reconciliation, input tax credit claims, and supplier payment analysis.
