An efficient audit does not start when the audit team arrives.
It starts months earlier, with preparation, planning and clarity over what will be required, and when.
Many audit overruns are not driven by technical complexity or regulatory change. They arise because audits begin before the underlying building blocks are in place.
Here, we set out the practical steps clients can take to prepare effectively for audit, minimise disruption and avoid unnecessary cost escalation.
Practical steps to take to prepare for audit
1. Understand the assumptions behind the audit
2. Identify risk areas before the audit team does
3. Treat the audit timetable as a critical control
4. Focus on quality of information, not volume
5. Maintain early and open communication to avoid late pressures
1. Understand the assumptions behind the audit
Every audit is planned and priced based on assumptions. This is unavoidable and entirely appropriate.
Those assumptions typically include:
Information will be complete, accurate and internally consistent
Key reconciliations will be prepared and reviewed
Accounting policies will be clearly documented and applied consistently
Significant judgements will be identified early
Internal controls will operate as described
The finance team will have sufficient capacity and experience
Information will be delivered in line with agreed timetables
Preparing for audit means testing those assumptions internally before the audit begins.
Where assumptions are unlikely to hold – for example due to team changes, system issues or complex transactions – early disclosure allows the audit to be planned more efficiently and avoids disruption later.
2. Identify risk areas before the audit team does
Auditors are required to respond proportionately to risk. Where risk is higher, audit effort must increase.
The most efficient audits are those where key risk areas are identified and discussed upfront, including:
Non-routine or complex transactions
Areas involving significant judgement or estimation
Impairment indicators or liquidity pressures
Control weaknesses or process changes
Changes in accounting policy or reporting framework
Early identification allows:
Appropriate audit resources to be planned
Specialists to be involved in a targeted way
Timetables to reflect realistic delivery points
Issues to be resolved before deadlines tighten
Late identification almost always results in compressed timelines, additional senior involvement and higher costs.
3. Treat the audit timetable as a critical control
Audit timetables are not administrative checklists. They are central to audit efficiency.
When information arrives late or in fragmented form:
Testing becomes less efficient
Review time increases
Rework multiplies
Senior escalation becomes more likely
Strong preparation includes:
Agreeing a realistic timetable before year end
Aligning internal deadlines ahead of external ones
Identifying critical path items early (such as tax, valuations and impairment)
Monitoring delivery against timetable in real time
Escalating slippage as soon as it arises
Early communication of delays allows adjustments to be made calmly and constructively.
4. Focus on quality of information, not volumeAudit efficiency is driven by the quality of information provided, not the quantity.
Well-prepared audit input is:
Clearly structured and logically presented
Consistent across schedules
Reconciled to the general ledger
Internally reviewed before submission
Supported by clear explanations of judgement
Time invested in preparation is almost always recovered through:
Fewer audit queries
Reduced rework
Faster review and clearance
More predictable delivery
Conversely, incomplete or poorly supported information increases audit effort even where the underlying accounting is sound.
5. Maintain early and open communication to avoid late pressures
The most difficult audit conversations are those held after work is complete.
Effective preparation includes establishing a habit of early dialogue when circumstances change, such as:
Unexpected transactions
Changes in trading conditions
Emerging control issues
Delays in key deliverables
Early discussion allows scope, timing and expectations to remain aligned and avoids unnecessary tension late in the process.
From a client perspective, transparency creates optionality. It preserves flexibility and reduces the risk of last-minute disruption.
Final Reflection
Preparing for audit is not about reducing scrutiny or cutting corners.
It is about creating the conditions for an efficient, high-quality engagement.
Clients who invest in preparation typically experience:
Fewer surprises
Less disruption to finance teams
More predictable audit timelines
Better control over cost
Stronger audit outcomes
An efficient audit is not accidental. It is planned, prepared for and actively managed.

We are always happy to have an early discussion around audit preparation, particularly where there are new transactions, changing conditions or internal developments. A short conversation upfront can often make a meaningful difference to how the audit progresses. Please speak to your usual advisor, or contact us.
