How to prepare for your first audit

You may have crossed the statutory audit threshold, taken on external investment, expanded into new markets, joined a group structure or reached a point where lenders, shareholders or other stakeholders want more assurance over the numbers.

However, your first audit can also expose issues that have been manageable, or even invisible, while the business was smaller.

Informal processes, undocumented decisions, inconsistent reconciliations, gaps in stock records, weak cut-off procedures and unclear evidence trails can all become much more important once an auditor needs to form an independent opinion.

In our view, the businesses that handle their first audit best are not always the ones with the most polished finance function.

They are the ones that understand the role that an audit serves, prepare early and deal with difficult areas before fieldwork begins.

Why the first audit is so impactful

A first audit often involves more work than future audits because your auditor needs to understand your business from the ground up.

We need to understand how the business operates, how income is generated, how costs are controlled, what systems are used, where key judgements sit and how reliable your financial records are.

We also need to look at opening balances, accounting policies, internal controls and the areas where there is a greater risk of error or where estimates and judgements feature.

This is why a first audit can feel more intrusive than you might have expected.

The questions are not limited to the year-end figures but rather go into processes, systems, controls, commercial decisions and the evidence behind key balances.

That is not because we want to make the process difficult.

It is because we need to obtain enough evidence to support our opinion and, for a first audit, there is no prior year audit file to rely on unfortunately.

Start preparing before the year end

The biggest mistake we see businesses make is treating the audit as something that starts after the accounts have been prepared.

A lot of the most useful opportunities to make the process smoother will have already passed by that point.

If stock counts have not been observed or contracts have not been reviewed, cut-off evidence has not been retained or key judgements have not been documented, the audit can become much harder than it needed to be.

My advice is to involve your auditor before the year end, especially if this is your first audit.

Having those discussions early allows us to identify the areas likely to need more evidence and agree what should be retained or reviewed.

This is particularly important where the business has complex revenue streams, stock, work in progress, group transactions, new funding arrangements, acquisitions, rapid growth, concerns around cashflow and going concern, etc.

These are rarely areas you want to reconstruct under time pressure after the event.

Get your reconciliations right

Strong reconciliations are one of the clearest signs that a business is audit-ready.

Bank, debtors, creditors, payroll, VAT, stock, intercompany balances, loans and fixed assets should all be reconciled and reviewed before the audit begins.

Make sure the balance agrees to the accounts, the supporting evidence is available and unusual items have been investigated.

For example:

  • Old debtor balances should be reviewed for recoverability
  • Creditor balances should be checked for completeness
  • Stock should be supported by count records and valuation evidence
  • Intercompany balances should agree on both sides
  • Loan balances should tie back to agreements and repayment schedules

If reconciliations are incomplete, out of date or unexplained, the auditor will usually need to spend more time testing, querying and resolving differences.

Review your controls before the auditor does

Many growing businesses reach their first audit with processes that have evolved quickly.

That is understandable but what worked when the business was smaller may not work once transaction volumes increase, teams expand and decision-making becomes more distributed.

However, weak controls can create audit issues.

This might include limited segregation of duties, poor approval processes, manual journal entries with little review, inconsistent purchase order controls, weak system access controls or a lack of evidence around management review.

We do need to understand whether the systems and controls around the numbers are reliable.

If controls are weak, more substantive testing may be required. In practical terms, that means more evidence requests, more sample testing and more time.

A first audit is a good opportunity to look honestly at whether your finance processes have kept pace with the business.

Do not underestimate group and related party issues

Group structures, connected companies, director loans, shareholder transactions and related party arrangements often attract more audit attention than management expects.

This is because they can affect disclosure, risk, commercial substance and the way balances are presented in the accounts.

If there are transactions with directors, shareholders, subsidiaries, parent companies or other connected entities, these should be clearly identified and supported.

Your auditor will want to understand the nature of the relationship, the terms of the transaction, whether balances are recoverable and whether the correct disclosures have been made.

Where these arrangements are not documented properly, the audit can slow down quickly.

This is especially true where intercompany balances do not agree, management charges have not been formalised, or loans exist without clear terms.

Prepare your evidence, not just your accounts

A set of accounts may show the final numbers, but the audit is built on evidence.

That evidence may include:

  • Invoices
  • Contracts
  • Bank statements
  • Payroll reports
  • Board minutes
  • Stock records
  • Lease agreements
  • Loan documents
  • Correspondence with customers or suppliers
  • Valuations
  • Forecasts
  • Management calculations

The quality of that evidence matters.

If documents are stored across inboxes, shared drives, individual laptops and accounting systems with no clear structure, the audit will be slower.

If the finance team has to keep searching for documents during fieldwork, the process becomes reactive and inefficient.

Before the audit starts, it is worth creating a clear evidence pack for the main balances and judgement areas.

The more organised this is, the easier it is for the auditor to work through the file without repeated follow-up queries.

Be realistic about timescales

A first audit should not be treated as a last-minute exercise.

If the audit is being driven by a filing deadline, lender requirement or group reporting timetable, you need to work backwards from that date and build in enough time for questions and review.

Delays often happen when clients assume the audit can be completed as soon as the accounts are ready.

In reality, if key evidence is missing or complex issues arise, sign-off may take longer.

This is why early communication is so important.

If there are deadlines that matter, tell your auditor at the start, not when the pressure is already on.

How to make your first audit smoother

My advice is fairly simple:

Prepare early, be organised and do not leave difficult areas until the end.

Before the year end, speak to your auditor about the areas likely to need attention.

Make sure reconciliations are complete, evidence is easy to access and key judgements are properly documented.

Review your controls, identify related party transactions, confirm group balances, prepare supporting schedules and make sure the finance team understands what will be needed.

A first audit will always involve work. It should. The auditor needs to understand the business and obtain enough evidence to support the opinion.

However, it does not need to be chaotic.

With early planning, clear records and honest conversations about the more complex areas, the first audit can be managed in a way that reduces disruption, controls costs and gives the business a stronger foundation for future growth.

If you are preparing for your first audit, speak to us early in the process. We can help you understand what is likely to be reviewed, identify potential issues before fieldwork begins and make the audit as efficient as possible.
