From Paper Files to a Connected Audit: Y. H. Lai & Co.’s First Six Months with Caseware

For Richard Lai, adopting Caseware Audit International was never simply about replacing paper with software.

As Partner at Y. H. Lai & Co., a Hong Kong CPA practice serving mainly private companies and SME groups, Richard had a broader objective: to strengthen the consistency, visibility and reviewability of the firm’s audit approach across staff and engagements.

The adoption of Caseware was an enhancement to the firm’s existing HKSA-based audit methodology, rather than a replacement for it.

Before Caseware, the firm’s established HKSA-based audit methodology was documented through a combination of paper working papers, spreadsheets and separate electronic documents. Engagements were subject to review at appropriate levels, including review by the audit manager and engagement partner before completion. Although the same firm methodology applied across engagements, the fragmented working-paper environment made consistent documentation, cross-referencing, engagement monitoring and review more time-consuming.

Richard saw an opportunity to strengthen the consistency, connectivity and visibility of the firm’s existing audit process.

“I wanted to standardise how our staff perform audits while safeguarding audit quality and improving efficiency,” he said.

That search eventually led Y. H. Lai & Co. to Caseware.

Looking for consistency, not just digitisation

Richard’s interest in Caseware began during the COVID period, when cloud collaboration became increasingly important. He wanted a system that would allow staff to continue audit work remotely while improving how information was connected across an engagement.

The firm’s previous process also carried practical burdens. Paper files accumulated over time and had to be retained and stored, sometimes offsite, creating cost and logistical pressures in Hong Kong.

But the deeper issue was not storage.

Richard wanted to embed the firm’s existing audit methodology more consistently within a connected digital workflow. He wanted clearer linkage between planning, risk assessment, relevant controls where applicable, audit procedures and conclusions, and greater visibility over what had been completed and reviewed.

Caseware therefore represented more than an electronic working paper system. The firm saw it as a longer-term investment in audit quality, consistency and future capability.

The first six months: learning before scaling

Adopting Caseware Audit International was one thing. Embedding a new way of working across the firm was another.

Richard quickly realised that implementation involved more than learning the software. The team needed to understand how the firm’s existing audit methodology—including engagement setup, risk assessment, review, sign-offs and completion—was implemented and connected within the new platform.

Rather than rolling the solution out to everyone at once, he created a small implementation team and rebuilt completed audits on the platform as training files, separate from the archived audit documentation. With the outcomes already known, staff could focus on learning the workflow without the pressure of a live deadline.

Questions were documented as they arose and gradually became internal guidance.

“We tested the workflow using completed engagements so that implementation issues could be identified and resolved in the training environment before the live rollout,” Richard said.

The approach required more effort upfront but helped the firm build confidence and establish a more repeatable process before scaling.

For Richard, the lesson was clear: successful adoption is not just about introducing software. It is about giving people the structure, time and leadership support to work differently.

Making the audit visible

Six months later, the most obvious change is not simply that work is digital.

It is that the audit is more visible.

“We have a more structured audit, and it is easier to review,” Richard said.

For Richard, that greater visibility makes it easier to monitor whether the required procedures have been properly performed, sufficient appropriate audit evidence has been obtained, review points have been resolved and the relevant work has been signed off before an engagement is finalised.

Review issues can be raised against the relevant working paper, assigned and tracked through clearance. Supporting evidence can be attached directly to the work it relates to. Engagement status and sign-offs are easier to monitor within the same environment.

But one area has been particularly valuable: the relationship between risks, relevant controls where applicable, assertions and planned audit responses.

Under the firm’s previous approach, those relationships were documented across separate working papers and spreadsheets, making cross-referencing and review less efficient. Caseware made those connections easier to follow.

More importantly, those links are now visible across the engagement as a whole.

The firm’s existing HKSA-based audit methodology was already well established. The HKICPA Audit Practice Manual provided practical implementation guidance, while Caseware made it easier to see and review how financial-statement-level risks, assertion-level risks and the resulting audit responses were connected across the engagement.

“With Caseware, we have a better view of how everything links together,” he said.

That may be one of the most significant outcomes of the implementation so far.

It has not simply provided another place to document the audit. It has helped make the structure of the audit itself more visible: how risks connect to assertions, how those risks influence responses, and where open items can be identified before final sign-off.

Solving the Hong Kong question

The implementation also surfaced a challenge Richard believes is particularly important for Hong Kong firms.

Caseware Audit International provides an ISA-based structure. While the Hong Kong Standards on Auditing are substantially converged with the ISAs, Hong Kong firms must also address applicable local requirements, regulatory expectations and relevant implementation guidance.

For Richard, the key priority was to configure the Caseware workflow so that compliance with the Hong Kong Standards on Auditing and applicable regulatory requirements was clearly evidenced, without unnecessarily duplicating work.

That created a practical challenge: how to reflect the firm’s HKSA-based methodology and relevant Hong Kong implementation guidance within the Caseware workflow. Richard has not treated the firm’s methodology and the platform as competing approaches.

The Hong Kong Standards on Auditing and applicable regulatory requirements remain the governing framework for the firm’s audits. The HKICPA Audit Practice Manual provides practical implementation guidance, while Caseware provides the structured environment in which the firm’s risk assessments, audit responses, conclusions and reviews can be documented and connected.

That distinction has shaped his view of technology adoption.

“When a firm is choosing a new way of performing audits or adopting that kind of platform, it is not simply purchasing software,” he said. “It also involves the firm’s methodology, quality-management processes, professional standards, training and supervision.”

Buying the software is only the beginning

Richard’s experience has also convinced him that audit transformation cannot simply be handed to staff and expected to happen on its own.

He cautions against the assumption that a firm can buy a solution, give it to the team and expect staff to work out the new platform workflow themselves.

Leadership involvement matters.

Richard argues that when a firm introduces a new way of working, senior leaders need to be closely involved in defining the process and helping staff adopt it consistently.

His advice to other firms is practical: establish a dedicated implementation team, use completed engagements as training cases, record recurring issues, build internal guidance and allow more implementation time than initially expected.

Technology provides structure. The firm must still establish and maintain the methodology, policies, procedures, training and supervision governing how its people work within that structure.

Building the foundation for efficiency

Six months into the journey, Richard is careful not to claim measurable time savings.

As the firm is still refining its templates, mapping and internal guidance, it is too early to quantify the time savings reliably. The clearest gains so far are improved consistency, visibility and documentation quality.

That is also how the firm describes its progress: the audit process is more structured, engagement status is more visible and review trails are clearer. Caseware has made the systematic documentation and linkage of risk assessments, audit responses and conclusions more visible and easier to review.

Efficiency remains one of Richard’s objectives, but it is the next chapter rather than a result he is ready to quantify.

The firm is continuing to refine templates, mapping and internal guidance, further develop its Caseware workflows for group audits and consolidation-related audit procedures, and look for ways to reduce administrative preparation so senior staff can spend more time on professional judgement and significant client issues.

Paper files and secure offsite storage were visible features of the former working-paper environment.

The deeper objective was to strengthen the consistency, connectivity and reviewability of the firm’s audit process.

Six months in, Y. H. Lai & Co. has established a strong foundation for a more connected audit process.

The visible change is digital.

The more important change is that the audit process is now more visibly connected.
