Your business can’t move forward on numbers you can’t trust.

We restore financial records to a state where every number can be relied upon – by you, your bank and the ATO.

When Your Financial Records Need More Than Maintenance – They Need Rebuilding

Every business reaches a point where the numbers need to be right. Whether you are transitioning from a previous accountant, correcting years of accumulated errors or preparing your books for a transaction – the starting point is always the same. You need financial records you can trust.

Prime Partners provides accounting clean-up, financial rectification and historical record reconstruction for Australian businesses that need to bring their financial position back to an accurate and reliable state before they can move forward.

We work with owner-managed businesses, growing SMEs and multi-entity groups across Sydney, regional NSW and nationally.

What Is Accounting Clean-Up?

Accounting clean-up is the process of reviewing, correcting and rebuilding a business’s financial records so they accurately reflect its true financial position. This goes well beyond standard bookkeeping – it involves forensic-level review of historical transactions, reconciliation of bank accounts, correction of coding errors and realignment of reporting with Australian Accounting Standards and ATO requirements.

For many businesses, accounting clean-up becomes necessary when financial statements no longer reflect reality. This might be because of a change in accountants, rapid growth that outpaced internal processes, or simply years of small errors compounding into material misstatements.

The goal is simple: to get your books to a position where every number can be relied upon – by you, by your bank, by the ATO and by anyone else who needs to trust your financial data.

What Is Financial Rectification?

Financial rectification takes accounting clean-up a step further. Where clean-up corrects the records, rectification addresses the compliance and regulatory consequences of inaccurate reporting.

This includes amending previously lodged BAS returns, correcting GST positions, rectifying payroll and superannuation obligations, and regularising your position with the Australian Taxation Office. In many cases, financial rectification also involves negotiating with the ATO to resolve outstanding lodgements, manage penalties and establish payment arrangements for historical liabilities.

Financial rectification is not about assigning blame for past errors. It is about establishing an accurate baseline so your business can operate with confidence going forward.

Our Accounting Clean-Up Services

Prime Partners provides a comprehensive range of accounting clean-up and financial rectification services. Each engagement is scoped to the specific issues affecting your business – there is no one-size-fits-all approach.

Historical Accounting Clean-Up

We review and correct your general ledger, chart of accounts and transaction history going back as far as necessary. This includes reconciling bank accounts, clearing suspense accounts, correcting misallocated transactions and ensuring your balance sheet accurately reflects assets, liabilities and equity.

For businesses with multiple years of accumulated errors, we work systematically through each financial period to establish accurate opening balances and carry-forward positions.


BAS and GST Reconstruction

Incorrect BAS lodgements are one of the most common issues we encounter. We reconstruct GST positions from source documents, identify overclaimed or underclaimed input tax credits, correct BAS reporting categories and prepare amended activity statements for lodgement with the ATO.

Where BAS has not been lodged at all, we prepare and lodge outstanding returns and work with the ATO to manage any resulting penalties or interest charges.


Payroll and Superannuation Rectification

Payroll errors create exposure across multiple areas – income tax withholding, superannuation guarantee, Single Touch Payroll reporting and employee entitlements. We review payroll records, identify discrepancies, calculate correct entitlements and prepare any necessary corrective lodgements.

For businesses with superannuation guarantee shortfalls, we calculate the Superannuation Guarantee Charge (SGC) including nominal interest and administration fees, and manage voluntary disclosure to the ATO where appropriate.


Prior Year Tax Review and Amendments

We review previously lodged tax returns to identify errors, missed deductions or incorrect positions. Where amendments are warranted, we prepare and lodge amended returns within the applicable amendment periods and manage any resulting tax liabilities or refunds.

This is particularly important for businesses that have changed accountants and discovered discrepancies in prior year positions.


Accounting System Repair and Rebuild

When the accounting system itself is the problem – misconfigured chart of accounts, broken integrations, duplicate data feeds or corrupted files – we repair or rebuild the system from the ground up.

We work primarily with Xero and MYOB, and can migrate data between platforms where a system change is the most practical path forward. Our rebuild process includes configuring the chart of accounts to match your business structure, establishing automated bank feeds, and setting up reporting templates aligned with your management and compliance requirements.


Entity Record Reconstruction

For businesses operating through multiple entities – companies, trusts, partnerships or combinations – we reconstruct the financial records for each entity, reconcile intercompany balances and establish a consolidated view of the group’s financial position.

This is critical for family groups, investment structures and businesses where transactions between related entities have not been properly documented.


ATO Position Regularisation

Outstanding ATO lodgements, undisclosed income, unpaid tax debts and penalty notices create compounding risk the longer they remain unresolved. We work directly with the ATO to regularise your position, including:

  • Lodging all outstanding returns (income tax, BAS, PAYG, STP)
  • Applying for remission of penalties and general interest charge (GIC)
  • Negotiating payment arrangements for historical tax debts
  • Managing voluntary disclosures where prior positions were incorrect
  • Addressing director penalty notices and personal liability exposure

Our approach is always to engage proactively with the ATO rather than waiting for enforcement action.


Financial File Preparation for Transactions

If your business is being prepared for sale, seeking external funding, entering a joint venture or undergoing due diligence, the financial records need to withstand scrutiny. We prepare your books to the standard required for these transactions, including normalised financial statements, proof of earnings, working capital analysis and clean audit trails.

Accurate financial records are not just good practice – they directly impact the value and terms you achieve in any transaction.

When Businesses Need Accounting Clean-Up

There is no single trigger that tells a business it needs accounting clean-up. However, the following situations are among the most common reasons businesses engage us for financial rectification services.

1

Transitioning from a Previous Accountant

Changing accountants often reveals issues that were not visible before. We frequently work with businesses that have received incomplete or disorganised files from their previous accountant, making it impossible to prepare current-year returns without first cleaning up the historical position.

2

Rapid Growth Outpacing Finance Processes

When revenue doubles but the bookkeeping process stays the same, errors accumulate quickly. Growing businesses often find that their chart of accounts, reporting structure and reconciliation processes are no longer fit for purpose. What worked at $500,000 in revenue does not work at $5 million.

3

Financial Statements Not Reflecting Reality

If your profit and loss statement does not match your bank balance, or your balance sheet includes assets and liabilities that do not exist, your financial records need attention. We work with businesses where the gap between reported figures and actual position has grown to the point where management decisions cannot rely on the numbers.

4

Re-establishing Confidence in Reporting

Sometimes the issue is not a single error but a general loss of confidence in the numbers. Directors and business owners who cannot trust their financial reports are operating blind. Accounting clean-up restores the integrity of reporting so that management decisions can be made with confidence.

5

Preparing Books for Funding, Due Diligence or Sale

Banks, investors and buyers all require financial records they can trust. If your books are not at that standard, the preparation process starts with a clean-up. We regularly assist businesses preparing for bank refinancing, private equity investment, trade sale or succession planning.

6

Correcting BAS, GST or Prior Year Tax Errors

Errors in BAS lodgements and tax returns create ongoing exposure. The ATO’s data matching capabilities mean that discrepancies are increasingly likely to be identified. Proactive correction is always preferable to waiting for an ATO review or audit.

7

Outstanding ATO Lodgements

Businesses with overdue BAS, income tax returns or STP reporting face escalating penalties and risk enforcement action. We bring lodgements up to date, often securing penalty remission by demonstrating a genuine effort to regularise the position.

Why Rectification Comes Before Strategy

At Prime Partners, we are clear about this: accurate financial records are the prerequisite for everything else. You cannot build effective tax strategy, cashflow planning or growth advisory on a foundation of unreliable data.

Without accurate records:

  • Cashflow decisions are based on assumptions – not actual position. Businesses overspend, underspend or miss opportunities because the numbers they are working from are wrong.
  • Tax positions cannot be planned – effective tax planning requires knowing exactly where you stand. If historical positions are uncertain, forward planning is guesswork.
  • Funding conversations become difficult – banks and investors will not advance capital based on financial statements that cannot be verified. Clean books are a prerequisite for any external funding.
  • Risk remains hidden – undisclosed liabilities, incorrect GST positions, superannuation shortfalls and outstanding ATO obligations create exposure that grows over time. Rectification surfaces these issues so they can be resolved.

This is why we always recommend completing the clean-up before engaging in broader business accounting and tax advisory work. The strategy is only as good as the data it is built on.

Our Approach to Accounting Clean-Up

Every accounting clean-up engagement follows a structured process designed to move efficiently from diagnosis to resolution.

1

Diagnose the Position

We start by understanding the full scope of the problem. This involves reviewing your current accounting system, assessing the quality of historical records, identifying outstanding lodgements and quantifying the gap between your reported position and your actual position.

The diagnostic phase typically takes one to two weeks and results in a clear scope document outlining what needs to be corrected, in what order, and with what expected timeline and investment.

2

Prioritise Corrections

Not everything needs to be fixed at once. We prioritise corrections based on regulatory risk, financial materiality and business urgency. ATO compliance issues and cash-impacting errors are addressed first, followed by balance sheet corrections and reporting improvements.

This approach means your business gets the most critical issues resolved quickly while the broader clean-up continues in the background.

3

Rebuild Reporting Integrity

Once corrections are complete, we rebuild your reporting framework. This includes configuring your accounting system for accurate ongoing reporting, establishing reconciliation processes and producing a clean set of financial statements that can serve as the reliable baseline going forward.

We also document everything we have done – what was corrected, why, and what the impact was on each financial period affected. This documentation is essential for ATO compliance and for your own records.

4

Transition to Ongoing Support

With the clean-up complete, we help you transition to a sustainable accounting and compliance model. For many clients, this means moving into our ongoing business accounting and tax advisory service. For others, it means establishing processes with their internal team or existing bookkeeper to maintain the accuracy we have established.

The objective is always to ensure that the problems we have fixed do not recur.

After Rectification – What Comes Next

Accounting clean-up is rarely the end of the journey. Once your financial records are accurate and your compliance position is regularised, you are in a position to pursue the business objectives that the mess was holding back.

Who We Work With

Our accounting clean-up and financial rectification services are designed for mid-market Australian businesses that need more than a bookkeeper but are not yet at the scale where a Big Four firm makes sense.

Family-Owned Businesses

Family businesses often operate with informal financial processes that work until they do not. Succession planning, family disputes, or simply growth can expose gaps in record-keeping that require professional rectification.


Growing SMEs

Businesses that have grown quickly often find their accounting infrastructure lagging behind. We help bridge the gap between where the systems are and where they need to be.


Multi-Entity Groups

Groups operating through multiple companies, trusts and partnerships need clear intercompany accounting and consolidated reporting. Where this has not been maintained, we reconstruct the position and establish proper group accounting.


Businesses Preparing for Scrutiny

Whether you are preparing for an ATO audit, bank refinancing, investor due diligence or business sale, clean financial records are non-negotiable. We bring the books to the standard required for external review.

Our team has extensive experience in accounting clean-up and financial rectification across a range of industries including professional services, construction, agriculture, healthcare, technology and retail.

Frequently Asked Questions

Will this disrupt day-to-day operations?
We design every engagement to minimise disruption. Most of our work is conducted off-site using secure access to your accounting system. We coordinate with your team to obtain source documents and information as needed, but the heavy lifting happens on our side. Your business continues to operate normally while the clean-up progresses.
How far back do you review?
As far back as necessary to establish accurate opening balances. For most engagements this means two to four financial years, though we have worked on rectifications spanning seven or more years where the issues required it. The diagnostic phase determines the scope.
Can this transition into ongoing accounting support?
Yes. Many of our clean-up clients transition into our ongoing business accounting and tax advisory service once the rectification is complete. This provides continuity and ensures that the accuracy we have established is maintained over time.
How long does accounting clean-up take?
The timeline depends on the complexity and volume of issues. A straightforward BAS correction might take two to four weeks. A comprehensive multi-year clean-up for a multi-entity group can take three to six months. We provide a clear timeline estimate during the diagnostic phase so you know what to expect.
What does financial rectification involve?
Financial rectification involves correcting the compliance and regulatory consequences of inaccurate financial records. This includes amending BAS returns, correcting GST positions, rectifying payroll and superannuation obligations, lodging outstanding tax returns and regularising your position with the ATO. It goes beyond simply fixing the books – it addresses the downstream effects of historical errors.
Can you fix BAS errors from previous years?
Yes. We reconstruct GST positions from source documents, prepare amended BAS returns and lodge them with the ATO. The ATO generally allows amendments to BAS returns within four years of the original due date. Where errors span multiple periods, we work through each systematically and manage the net position with the ATO.
Do you handle ATO debt negotiations during clean-up?
Yes. ATO debt management is a standard part of our financial rectification service. We negotiate payment arrangements, apply for penalty and interest remission, manage voluntary disclosures and work with the ATO to establish a sustainable path to resolving outstanding liabilities. Proactive engagement with the ATO consistently produces better outcomes than waiting for enforcement.
What is the difference between accounting clean-up and a regular audit?
An audit is an independent examination of financial statements to provide assurance that they are materially correct. Accounting clean-up is the process of actually correcting the records. In many cases, a clean-up is necessary before an audit can be conducted – because the records need to be accurate before they can be independently verified.
Can you help prepare financial records for business sale?
Absolutely. Sale-ready financial records need to be accurate, well-documented and capable of withstanding due diligence scrutiny. We prepare normalised financial statements, reconcile all balance sheet items, document any adjustments and ensure the books tell a clear and defensible story. Clean records directly impact the valuation and terms you achieve.
How much does accounting clean-up cost?
We scope every engagement individually based on the complexity of the issues, the number of entities involved, the volume of transactions and the number of financial periods requiring correction. We provide a fixed-fee quote after the diagnostic phase so there are no surprises. For straightforward single-entity clean-ups, fees typically start from $5,000. Complex multi-entity, multi-year rectifications are quoted on a project basis.
