How to prepare for your first audit?

1. Talk to your employees
One key factor in ensuring a successful audit is preparing your employees and setting the right tone.

The word “audit” can cause worry and concern if your employees don’t understand the context and reasons behind the audit.

When the auditors visit your offices, they will talk to employees at every level in your company, and it’s essential to make sure they are comfortable.

Empower your employees to answer questions, or defer to you or others in your organisation when it’s appropriate.

Assign roles and point people for the various audit areas.

Communicate this internally and also to the auditors, and they will know the right person to go to when questions arise.

Stress the importance of being open and honest with the auditors.

Establishing an environment that treats the auditors as partners will help ensure they are as effective as possible.

2. Draft your process and control documents
If you don’t already have detailed process and control documents, draft them ahead of the audit.

Auditors are required to document their understanding of your internal control environment, and no one knows your internal control environment better than you and your employees.

By documenting your processes and controls, you can ensure the auditors hit the ground running and understand all the strengths of your controls.

At a minimum, consider compiling the following process and control documents:

  • Cash in-flows
  • Cash out-flows
  • Controls over financial reporting and month/year-end close
  • Information technology general controls

Consider if you have any internal documents that you can leverage to turn into the process and control documents.

3. Check all the records
The auditors will be requesting a significant number of documents supporting transactions and business activities.

Making sure you have a complete set of records upfront will save you the headache of having to recreate them during the audit process.

  • Ensure you have support for transactions (invoices, purchase orders, cash payments/receipts).
  • Gather all contracts, lease agreements and organisational documents.
  • Review your notes and records and make sure you’ve documented any unusual items or transactions, huge ones.
  • Reconcile your books and check that your subsidiary ledgers agree to your general ledger.
  • When you’re providing schedules to the auditors, make sure they agree to the general ledger. You don’t want the auditors spending their time (or your money) reconciling reports that you can reconcile more easily.

4. Prepare for a cost-effective audit
Several things can be done to ensure that an audit runs as efficiently as possible.

Firstly, make sure that all accounting staff is available during the time that the auditors are on-site with you.

Secondly, below is a summary of some of the primary documents to be prepared in advance of the audit. If the records are all readily available, disruption to your staff members during the audit will be minimised:

  • All primary accounting records
  • Diagram showing the structure & ownership of the company/ group of companies
  • Year-end bank reconciliation & statements available for the entire period for all bank accounts
  • Breakdown of all balance sheet amounts with invoices to evidence items such as fixed asset additions, prepayments & accruals
  • Aged debtors’ and creditors’ listing
  • Wages records and P11D returns
  • Stock reports
  • All hire purchase and leasing agreements
  • VAT returns and workings

Copies of all meeting minutes held during the year and details of any changes in share ownership.

How long does it take to complete an audit?

The time to start and complete an audit is depended on the size of the company and the company’s internal bookkeeping.

Usually from beginning to end audits are typically scheduled for three months – four weeks of planning, four weeks of fieldwork and four weeks of compiling the audit reports.
