Backlog Accounting Services
Catch Up On Your Books. Get Back On Track. Stay Compliant.
Falling behind on your bookkeeping and tax lodgements happens more often than you’d think — and you’re not alone. Whether you’re months or even years behind, PrepMyBook is here to help you get up to date quickly, accurately, and stress-free.

What Is Backlog Accounting?
Backlog accounting (or catch-up bookkeeping) means we step in to sort out any gaps in your books and bring all your financial records up to date. We fix errors, reconcile transactions, prepare overdue BAS or tax returns, and make sure your accounts are accurate and compliant with ATO requirements.
Who Needs It?
Backlog accounting is perfect for:
- Small businesses that got too busy to keep up with regular bookkeeping
- Sole traders who never had time to reconcile bank accounts or keep receipts organised
- Startups that grew quickly and now need clean books for funding or investment
- Businesses facing ATO deadlines or audits with missing paperwork
- Anyone wanting a fresh start with their books clean, clear, and correct
How We Help
When you choose PrepMyBook for backlog accounting, you get:
- Detailed File Review: We assess the current state of your records to identify missing information, errors, or compliance risks.
- Catch-Up Bookkeeping: We go through your bank statements, invoices, receipts, and payroll data — reconciling every transaction and correcting mistakes.
- BAS & Tax Lodgements: We prepare and lodge any outstanding Business Activity Statements (BAS) or overdue tax returns to keep you in good standing with the ATO.
- ATO Liaison: Running behind can feel stressful — but you don’t have to deal with the ATO alone. We handle correspondence with the ATO on your behalf where needed.
- Modern Systems: We move you onto smart, easy-to-use bookkeeping software if you’re not already set up — so you stay up to date going forward.
- Practical Advice: Once your books are clean, we help you put better systems in place to prevent backlogs happening again.

- Lodge your BAS and tax returns with confidence
- Avoid late fees and penalties
- Get a true picture of your business performance
- Make better business decisions
- Focus on growing, not worrying
