Accounting workpapers software and best practice guide for Australian accountants

Every financial statement, tax return, audit, or advisory recommendation relies on records that verify how you reached your conclusions. These documents are your accounting workpapers.

Good workpapers are accurate, complete, and consistent, helping speed up reviews and defend your conclusions during an audit without requiring further explanation

In this guide, you’ll learn what accounting workpapers are, workpapers best practices, and how you can standardise quality across your firm with accounting workpapers software.

Key takeaways

• Accounting workpapers provide documented evidence behind a client’s financial statements and tax return. 
• Workpapers serve as your defence if the ATO or a practice reviewer asks questions.
• Good workpapers are cross-referenced, review-ready, and complete enough for partner sign-off without chasing for more information.
• Standardised templates and accounting workpapers software help reduce errors and speed up reviews.

What are accounting workpapers

Accounting workpapers are documents that show the calculations, analysis, supporting evidence, and professional judgment behind every financial statement and tax position. In short, they tell the story behind the numbers.

In practice, this serves two purposes:

1. Communication: They help another accountant, partner, or regulator know the work you’ve done, follow your reasoning, and see the evidence for your conclusions.
2. Defence: They provide evidence that supports your conclusions during an audit or review.

Essentially, your workpapers are a communication tool and a line of defence. That’s why the best workpapers are “self-explanatory,” meaning they communicate and defend the engagement without needing additional explanation from you.

Types of accounting workspapers

• Trial balances and lead schedules: General ledger account summaries used to verify balances in financial statements and serve as the starting point for preparing the engagement.
• Reconciliations and supporting schedules: Workpapers used to check account balances against supporting records. Examples include bank reconciliations, aged accounts receivable and payables, inventory valuation statements, fixed asset depreciation schedules, and loan amortisation schedules.
• Adjusting journal entries (AJEs): Entries that correct errors or year-end adjustments, completed before the finalisation of financial statements.
• References to supporting documents: Includes source documents, like invoices, trust deeds, board meeting minutes, bank statements, and external confirmation letters, as well as explanations and analysis.
• Methodology, calculations, and analysis: Documents explaining the assumptions, formulas, accounting treatments, and professional judgement in statements and conclusions.
• Review notes and sign-offs: Records the preparer, reviewer, and approver of the work, as well as comments and feedback given during the review process.

Together, these workpapers form a complete engagement file that supports your work from preparation to partner sign-off.

Take note: workpapers are different from source documents. Source documents prove a transaction occurred, while your workpapers use source documents to prove a financial statement is accurate.

For example, when an auditor wants to verify your client’s financial status, they won’t look for their receipts (source document). Instead, they’ll look for an Accounts Payable aging schedule (workpapers) to see those receipts and your professional analysis.

Why accounting workpapers are important

Accounting workpapers provide an evidence trail behind every financial statement or tax return, making these statements transparent and reviewable. It is also outlined by the Auditing and Assurance Standards Boards, which sets out the legal basis for audit documentation under the Corporations Act.

This transparency is necessary when:

• A partner reviews the engagement.
• Another team member takes over the file.
• The ATO or a practice reviewer audits the file or asks questions.

Other reasons workpapers are important to accounting firms are that they help:

• Produce accurate work: They help you create a clear, well-supported path from a source document to reported figures.
• Speed up reviews and improve accountability: They help reviewers understand your reasoning, spot issues faster, and approve confidently.
• Defend your work: They create an audit trail if the ATO ever questions you.
• Transfer knowledge between team members: They make it easier for another accountant to understand your client’s history, the work done for them, and important conclusions.
• Reduce duplicated work: By separating permanent files (long-term client information) from current files (year-specific documentation), you can reuse standing information instead of recreating the same documents every year.

Given the evolving compliance landscape and changes that came with the latest Federal Budget, your firm needs to be more organised than ever.

Manual vs automated workpapers

Accounting workpapers software uses digital technologies and automation to standardise templates, link source documents, and streamline reviews. Meanwhile, manual workpapers rely on manual data entry and calculations, performed via spreadsheets or Word documents.

Manual workpapers work for a small client base. Software removes that friction as your firm grows, easing the process of maintaining workpapers for accountants.

5 accounting workpapers best practices

Good workpapers are “self-explanatory,” meaning reviewers don’t need to chase you for more information. To achieve this, make sure your workpapers are consistent, cross-referenced, and review-ready.

As a benchmark, ask yourself: Could another accountant open this file, understand what I've done, and come to the same conclusion without consulting me? If yes, you’ve likely built strong workpapers.

1. Use standardised templates

Standard templates create uniformity, making it easier for reviewers to find information faster and spend more time assessing the quality of work. This supports quality control, which is mandatory for firms in public practice under APES 320.

2. Establish a standard for documentation throughout your company

Use the same formatting, naming conventions, and level of detail across your firm’s workpapers. You’ll find reviews becoming more efficient, new staff getting up to speed faster, and uniform quality being maintained better across engagements.

3. Cross-reference supporting data

To establish a transparent audit trail behind statements and figures, use index codes and tick marks to link related numbers, tests, and source documents.

Schedules and figures are linked by index codes. Tick marks indicate that those figures have undergone review procedures.

For example:

• A1: Cash reconciliation
• A2: Bank statements
• ✓: Agreed to source document

You may cross-reference a cash balance in the trial balance to A1, where you’ve prepared the bank reconciliation. You may also link this to A2, which has relevant bank statements. Adding ✓ says you’ve checked the reconciliation against source documents.

4. Link source documents

Show your evidence behind your conclusions. Do this by linking out to your client’s exact files that support your calculations.

These source documents can include:

• Bank statements
• Loan agreements
• Trust deeds
• Asset purchase invoices
• ATO correspondence

5. Maintain a clear review trail

Show auditors and external reviewers that your papers have been thoroughly reviewed by including:

• Who prepared it and when
• Who reviewed it and when
• All review notes, clearances, and amendments done during the review process

Cross-references and supporting data

• Does each important figure have a link to the appropriate supporting document?
• Have I accurately cross-referenced each figure?

Reasoning and calculations

• Are all formulas, computations, and reconciliations correct?
• Is it possible for another accountant to understand my logic without additional clarification?

Completeness and consistency

• Have I used my firm’s documentation standards?
• Have I resolved any review notes and signed off?

Step 2: Reviewer does detailed inspection

Your goal is to make sure the workpapers are complete, accurate, and ready for partner review. When reviewing, ask:

Technical accuracy

• Does the work comply with accounting standards and firm policies?
• Are the calculations used appropriate?

Completeness

• Is all supporting evidence included
• Are important balances and judgements clearly explained?

Review points

1. Have I given clear review notes?
2. Have all previous review notes been addressed?

Step 3: Partner gives final authorisation

Your goal is to confirm that the engagement is ready for client delivery. When reviewing, ask:

Professional judgement

• Have significant estimates, risks, and judgements been supported and explained?

Final review

• Do the workpapers fully support the financial statements, tax return, or other client deliverables?

Approval

• Have all review points been cleared and the engagement signed off?
