Signs you need bookkeeping clean up
- Bank accounts don’t reconcile or bank feeds have duplicated/missing transactions.
- BAS/GST figures look wrong, or past BAS have not been lodged on time.
- Payroll errors: STP mismatches, unpaid super, leave balances off, or year-end summaries don’t agree.
- Large balances in suspense/clearing/undeposited funds or loan/director accounts.
- Receivables and payables aging reports don’t reflect reality.
- Reports change when filters/dates change, suggesting coding inconsistencies.
- Software migration left duplicated contacts, items, or out-of-balance opening entries.
How bookkeeping clean up usually works
A practical clean up follows a structured workflow so you know what is happening and why:
- Rapid review (scoping): access your Xero/MYOB/QBO file, identify key issues, confirm periods affected, and check BAS/payroll status.
- Triage and stabilise: stop error sources (broken bank feeds, rules, add-on syncs), protect data, and agree priorities and milestones.
- Reconcile and correct: re-code transactions, reconcile bank/credit/loan accounts, fix GST, rebuild AR/AP where needed, and correct opening balances.
- Payroll audit: verify employee details, earnings, super, leave, STP submissions and EOFY alignment; lodge corrections if required.
- BAS and compliance: prepare or amend outstanding BAS with a registered BAS/tax agent and plan ATO communications if needed.
- Handover and prevention: provide a summary of fixes, updated processes, and a simple month-end checklist to keep books clean.
What’s included: a typical clean up checklist
- Bank, credit card and loan reconciliations (including feed fixes and duplicate removals).
- Coding review and rework with correct GST treatments.
- Aged receivables/payables cleanup and debtor/creditor matching.
- Payroll and STP health check, superannuation clearing, leave balance review.
- Chart of accounts tidy, tracking categories, and corrected opening balances.
- BAS preparation or amendments by a registered BAS/tax agent.
- Documentation: decisions made, journals posted, and a prevention checklist.
Scope changes if your file includes inventory, projects, multi-currency, or consolidations. Complex setups simply require a slightly longer runway and tighter milestones.
Australian context to keep in view
- GST and BAS: incorrect coding compounds each quarter. Clean up should reconcile GST control accounts to lodged BAS.
- Payroll, STP and super: payroll corrections may require updated STP events and super catch ups to stay compliant.
- ATO communication: if you are behind, plan lodgement order and discuss timeframes with the ATO early.
If your priority is purely overdue work, see Catch Up Bookkeeping. If your issue is BAS-specific, see BAS Agent Services. For payroll/STP, visit Payroll Services.
Pricing and timeframes in Australia
Clean up is usually quoted after a quick file review. Typical ranges help set expectations:
- Light tidy (minor reconciliations, a few corrections): $600–$1,200, 1–3 business days.
- 1–2 BAS periods with payroll checks: $1,200–$3,000, 1–3 weeks depending on volume and responsiveness.
- Multi-year or multi-entity with inventory/projects: $3,000+ with phased milestones and weekly updates.
Pricing depends on transaction volume, number of accounts, software/app complexity, and whether BAS amendments or payroll corrections are required. Ask for a staged plan so you see outcomes early.
Software we clean up
Most Australian small businesses use one of the following cloud platforms and connected apps:
- Xero: bank feeds, rules, tracking categories, Hubdoc/receipts, payroll/STP, projects.
- MYOB: AccountRight/Business, bank feeds, items, payroll/STP, BAS linkages.
- QuickBooks Online: banking rules, products/services, payroll/STP, app integrations.
The important question isn’t just “Do you use X?”—it’s “Can you explain the workflow and show the corrected reports?” Choose providers who can do both.
Clean up vs catch up bookkeeping
Catch up processes missing periods so reports exist. Clean up fixes accuracy issues so those reports can be trusted. Many businesses need both—process the backlog, then correct past errors and close with reconciled, BAS-ready numbers.

What to compare before you commit
Scope
Confirm the scope covers reconciliations, GST/BAS, payroll/STP, AR/AP, opening balances and documentation—not just “recode a few lines”.
Software fit
Ask for examples in your platform (Xero, MYOB, QBO) and whether they review bank feeds, rules and app connections to stop errors at the source.
Turnaround and communication
Agree milestones, update rhythm, and how urgent issues and ATO deadlines are handled during busy periods.
Commercial fit
Compare fixed-fee vs hourly, inclusions/exclusions, whether BAS is supervised by a registered agent, and options for ongoing month-end support.
What to prepare before the clean up starts
- Read-only access to your accounting file and any connected apps.
- Latest bank/credit card/loan statements for all accounts.
- Payroll reports, STP history, superannuation records and payment proofs.
- Copies of lodged BAS/IAS and any ATO correspondence.
- Notes from prior accountant/bookkeeper, including opening balances and journals.
- List of known issues or deadlines (e.g., overdue BAS, upcoming finance applications).
Best next steps
Write down the outcome you need: “lodge last two BAS”, “fix payroll/STP errors”, “prepare for finance”, or “clean file for better reporting”. Use that to drive scope, price and timeframe—not just the title of the service.
Then shortlist providers who can explain their approach, show example checklists, and provide a simple prevention plan once the clean up is complete.
Frequently asked questions
What does bookkeeping clean up usually involve?
It covers reconciliations, coding and GST fixes, AR/AP cleanup, payroll/STP checks, super clearing, corrected opening balances and documentation. If BAS are involved, a registered BAS/tax agent should supervise lodgements.
Is clean up the same as catch up bookkeeping?
No. Catch up processes missing periods; clean up corrects errors and resets workflows. Many businesses need a blend of both.
How long does it take?
Minor fixes: 1–3 days. One to four quarters: 1–3 weeks. Multi-year or complex files: several weeks, depending on data quality and responsiveness.
How much does bookkeeping clean up cost?
Typical ranges: $600–$1,200 for light tidy, $1,200–$3,000 for 1–2 BAS periods, and $3,000+ for multi-year/multi-entity work. Get a scoped quote after a quick file review.
Which software can you clean up?
Xero, MYOB and QuickBooks Online are the most common. Good providers also review bank feeds, rules and connected apps to prevent repeat errors.
Will a clean up remove ATO penalties?
No one can guarantee it. Accurate lodgements and proactive ATO contact help. A registered BAS/tax agent should handle ATO discussions.
Do I need a BAS agent?
Yes, if your clean up includes GST/BAS or PAYG Withholding lodgements. Look for registration and experience with amendments if corrections are needed.
