Keep the source evidence
A useful preparation process connects each recorded transaction to an invoice, receipt, statement or other original document. Store documents in a retrievable way and keep enough context for a reviewer to understand what the purchase or sale relates to.
Separate recording from treatment
A workbook can capture dates, amounts, supplier names and source references. Whether GST applies, which timing method applies and how an amount belongs in a return are professional judgement questions when the facts are unclear.
Create an exceptions list
Flag uncertain, missing or mixed-use items rather than forcing a category. An exceptions list gives an accountant or registered BAS agent a cleaner review path and preserves the reason an item needs attention.
Choose the right tool boundary
BASReady Tracker AU is for administrative record-keeping and BAS preparation. It is not tax software, accounting software, advice or official BAS lodgement. For a fuller comparison, read BAS tracker versus tax software.
