Audit Readiness Checklist: What UK Companies Should Prepare Before Fieldwork

An audit usually becomes stressful for one reason: the finance team starts preparing after fieldwork has already begun. Missing reconciliations, unsupported balances and changing figures lead to repeated questions, additional work and pressure on everyone involved.

Good audit readiness does not mean producing a perfect file or trying to anticipate every sample. It means closing the year properly, preparing reliable schedules and making the evidence behind the accounts easy to follow. Here is what a UK company should have ready before its external auditors begin fieldwork.

Start With Clear Responsibilities

Agree the audit timetable early and work backwards from the accounts approval, lender reporting and Companies House filing dates. Assign one person to manage the request list and give each schedule an owner and internal deadline.

Before fieldwork, confirm:

• The scope of the audit and reporting framework
• The expected date for draft accounts
• Dates for stock counts and fieldwork
• Who will answer questions in each business area
• When the audit committee or board will approve the accounts
• Secure arrangements for sharing information

Management prepares the financial statements and remains responsible for the accounting judgements within them. The auditor independently obtains sufficient appropriate evidence and gives an opinion on whether the accounts are free from material misstatement. An audit provides reasonable rather than absolute assurance.

Close the Books Properly

Do not send the auditor a trial balance that is still changing. Complete the year end close, post known adjustments and investigate unusual balances first. If figures change after fieldwork starts, earlier audit work may need to be repeated.

Your final audit pack should include:

• Final trial balance mapped to the draft financial statements
• Full nominal ledger and year end journal listing
• Draft statutory accounts with supporting disclosure schedules
• Prior year audit adjustments and management letter actions
• Corporation Tax, VAT and payroll reconciliations
• A clear record of any late adjustments

Every lead schedule should agree to both the trial balance and the draft accounts. Add brief explanations for unusual movements, large balances and significant changes from the prior year.

Reconcile Key Balances

A reconciliation is more useful than a spreadsheet containing unexplained numbers. It should identify the source of the balance, agree to the ledger and show how differences were investigated.

Auditors may obtain confirmations directly from banks, customers or other third parties. The revised external confirmation standard strengthens control over digital confirmations and requires exceptions to be investigated, so provide accurate contact details but allow the auditor to control the request and response process.

Prepare Supporting Evidence

An auditor needs evidence, not only explanations. A contract, invoice, bank statement or board minute will generally carry more weight than an unsupported verbal response.

Organise the following in advance:

• Sales and purchase invoices with proof of delivery where relevant
• Customer and supplier contracts
• Bank and loan correspondence
• Lease and hire purchase agreements
• Insurance documents and legal correspondence
• Board and shareholder minutes
• Details of related parties and connected transactions
• Post year end management accounts
• Evidence supporting grants, provisions and contingent liabilities

Use consistent filenames and cross reference each document to the request list. Avoid uploading entire folders when only one item has been requested. A focused response is easier to review and is less likely to create unnecessary follow up questions.

Document Accounting Judgements

The most time consuming issues are often estimates rather than routine transactions. Management should document the method, data and assumptions used before the auditor asks.

Prepare short papers for significant areas such as:

• Revenue recognition and contract cut off
• Bad debt and expected credit loss provisions
• Inventory obsolescence
• Asset impairment
• Useful economic lives and depreciation
• Provisions and contingent liabilities
• Share based payments or business combinations
• Related party transactions

A strong paper explains the accounting policy, the available evidence, the calculation and why the conclusion is reasonable. Include evidence that does not support management’s preferred answer as well as evidence that does. Auditors apply professional scepticism and look for contradictory as well as corroborative information.

Support Going Concern

Do not treat the going concern assessment as a short paragraph added to the accounts at the last minute. Directors should carry out and document their own assessment using current financial information, realistic assumptions and an appropriate assessment period. The external auditor will then evaluate management’s assessment and consider whether the going concern basis used in the financial statements is appropriate.

Prepare board approved cash flow forecasts that connect clearly to your accounting records and recent trading performance. The forecasts should explain assumptions about revenue, margins, operating costs, working capital and capital expenditure. If the business relies on loans, overdrafts or shareholder support, include the relevant agreements, facility limits, repayment terms and written evidence of continuing support.

Management should also prepare realistic sensitivity analysis. This should show what could happen if sales fall, costs increase, customers pay more slowly or funding becomes unavailable. Where forecasts suggest limited headroom, document the actions available to management, such as reducing expenditure, refinancing debt, obtaining additional capital or changing investment plans.

Plan for Inventory and Site Visits

If inventory is material, agree the stock count date and locations with the external auditors well before year end. Provide written count instructions, freeze stock movements where practical and separately identify damaged, obsolete, consignment and third party stock.

The final inventory report should reconcile count results to the ledger. Keep records of count differences, adjustments, transfers around year end and purchase and sales cut off. ISA UK 501 contains specific audit evidence considerations for selected items, including inventory.

Avoid Common Delays

The issues that most often slow fieldwork are preventable:

Changing Figures

Provide a final trial balance that agrees to the draft financial statements. If an adjustment is necessary after fieldwork begins, keep a clear change log showing the entry, reason, supporting evidence and person who approved it.

Missing Reconciliations

Complete bank, VAT, PAYE, payroll, loan, debtor and creditor reconciliations before fieldwork. Investigate differences rather than carrying unexplained amounts into the audit pack.

Unsupported Balances

Each material balance should have a clear schedule and suitable evidence. A spreadsheet containing figures is not enough if it does not explain the source of the balance or agree to the ledger.

Late Documents

Gather contracts, board minutes, invoices, loan agreements and legal correspondence before fieldwork. Late documents can change the auditor’s risk assessment and create further testing.

Weak Forecasts

Ensure that cash flow forecasts are approved, mathematically accurate and supported by reasonable assumptions. Explain how the forecast connects to actual results and how management would respond to an adverse scenario.

What Happens During Fieldwork?

The audit team will update its understanding of the company, assess risk, test selected controls and transactions, challenge significant estimates and evaluate financial statement disclosures. As audits are risk based, more work is directed toward balances and disclosures with a greater risk of material misstatement.

Keep the request tracker current and answer questions completely. If an item is unavailable, explain why, state when it will be available and identify alternative evidence. A clear answer is more useful than several partial uploads.

How Reflex Accounting’s External Auditors Help

Reflex Accounting’s external auditors agree the timetable, information requirements and key risk areas before fieldwork begins. The team uses a tailored, risk based approach under International Standards on Auditing UK and works across UK GAAP, including FRS 102 and FRS 101, and IFRS where applicable.

Clients receive a structured request list, secure document sharing and direct communication throughout the engagement. Potential reporting issues, weak reconciliations and technical accounting matters can therefore be discussed early rather than appearing as surprises near the signing deadline. Where the audit identifies control or reporting weaknesses, the team explains the practical implications and provides clear recommendations while preserving the independence required of an external auditor.
