Keep evidence for every figure
Store sales records, supplier invoices, receipts, platform statements, bank records and calculations used to determine business use.
Make records readable
Digital copies should remain clear, complete and accessible. Record the merchant, date, amount, GST treatment and expense category.
Reconcile regularly
Recording transactions weekly reduces missing receipts and makes the quarter-end review more reliable.
