Why does the GST amount change when I allocate a receipt to an invoice

When a receipt is entered, Law App assumes standard 10% GST as a placeholder. Once allocated to a bill, it recalculates GST based on the actual breakdown:

Some items (like search fees) may be GST-free.

Others (like service fees) may have partial GST.

Tip: For cash-based GST reporting, always allocate receipts before running BAS.
