Before You Start: Gather the Right Documents
A successful begins with a complete view of what you already have and what’s missing. Start by collecting bank statements, merchant statements from payment providers, and any sales reports you use to track income. Gather bookkeeper Perth invoices, receipts, and bills that support transactions, including both digital records and paper copies. When you can clearly map each transaction to a document, cleanup becomes faster and far less error-prone.
Next, capture your current accounting tools and settings so nothing important gets overlooked. Identify your accounting software, login access, and any connected apps such as payment gateways, payroll systems, or expense tools. List recurring expenses like subscriptions, insurance, and software fees, because these often create messy categories if left unmanaged. Finally, review whether you have multiple bank accounts or card accounts used for business spending, as mixing streams is a common source of reconciliation issues.
Audit Your Transactions: Spot Errors and Inconsistencies
Once your documents are assembled, run a structured audit of your transaction history before making changes. Check for duplicates, reversed charges, and transactions that appear without matching invoices or receipts. Look for uncategorised or misclassified items, such bookkeeping cleanup as personal expenses entered as business costs or fees posted to the wrong account. If you use a clearing account, verify that balances are moving correctly and not hiding unresolved transactions.
Then focus on reconciliation quality, because this is where cleanup typically delivers the biggest improvements. Compare each bank statement line to what appears in your accounts and note any gaps or timing differences. Ensure GST treatment is consistent for sales and purchases, especially where invoices have been issued or received with differing tax codes. For businesses that handle multiple income streams, confirm that each revenue type is categorised consistently so reporting remains meaningful.
Fix the Books: Clean Up Categories, GST, and Payroll Links
After identifying problems, tackle cleanup in a controlled order to prevent rework. Start by correcting categories for expenses and income, using a simple chart of accounts structure that matches how you actually operate. Reconcile GST codes carefully, because errors here can distort both cash flow visibility and tax preparation. If you find transactions that can’t be supported by documents, flag them for clarification rather than forcing them into the wrong category.
If your business includes payroll or contractors, confirm that wages, superannuation, and contractor payments are recorded consistently. Verify that payroll payments and liabilities reconcile to the bank transactions and that any clearing accounts are correctly handled. For businesses with inventory, check stock-related entries and ensure cost of sales logic aligns with your purchasing and sales processes. When these relationships are correct, your financial statements become more reliable for decision-making.

Start with document gathering, then audit transactions for duplicates and missing links, and finally fix categories, GST handling, and any payroll connections that affect reporting accuracy.
