1. The Challenge: Outsourcing Was Not Delivering Expected Results
The client was already outsourcing compliance work through other providers. However, the arrangement was creating additional challenges instead of improving operational efficiency.
The main issues included:
Inconsistent Work Quality
Deliverables frequently fell short of the firm’s expectations in terms of turnaround time and first-draft quality.
Lack of Resource Continuity
Different people handled different jobs, resulting in repeated training and explanations about the firm’s working-paper standards and preferences.
Additional Review Work
The partner spent considerable time correcting issues, reviewing files and explaining requirements to new resources.
The client needed a dependable outsourcing partner who could provide consistent quality and long-term resource continuity.
2. Our Approach: A Flexible, Seat-Based Outsourcing Model
After understanding the client’s requirements, Nippon Data Consulting recommended a dedicated seat-based outsourcing model instead of a traditional per-job or ad-hoc arrangement. However, the client was initially unsure whether the workload justified hiring a full-time dedicated resource.
To address this concern, we proposed a flexible arrangement:
- Half-Seat Commitment: One experienced senior resource working half-time exclusively on the client’s assignments.
- Hourly Overflow Support: Additional work beyond the half-seat capacity was billed at an hourly rate.
- Flexible Scaling: The engagement could grow as the client’s workload and confidence increased.
This approach allowed the client to begin with a lower commitment while assessing the quality and reliability of our services.
3. Building Trust Through Quality and Consistency
We assigned a senior professional with more than five years of experience specialising in UK statutory accounts and corporation tax.During the initial 15–20 days, the resource focused on understanding the firm’s working-paper formats, review expectations and internal processes.The results helped establish confidence in the engagement.Within just one month, the client requested an upgrade from a half-seat to a full seat.
There was one important condition: the same professional had to continue handling the client’s work for the foreseeable future.
This highlighted the importance of continuity and building a long-term working relationship.
4. Scaling the Accounting Outsourcing Partnership
As turnaround times improved and first-draft quality became more consistent, the client gradually increased the volume of work assigned to Nippon Data Consulting.
The engagement expanded in four stages:
- 0.5 Seat: Initial trial engagement.
- 1 Seat: Full-time dedicated resource after the first month.
- 2 Seats: Additional resources as the workload increased.
- 6 Seats: A dedicated six-member team supporting the client’s operations.
What started as a half-seat engagement eventually developed into a six-member dedicated accounting team.
5. The Current Engagement: A Reliable Extension of the Client’s Practice
Today, six dedicated seats support the client’s accounting operations.The client has also expanded its in-house team to work directly with our resources, creating a more coordinated workflow.
The partnership now supports:
Smooth Job Handoffs
Assignments, reviews, queries and revisions move between both teams with minimal friction.
Consistent Accounting Support
The same experienced professional continues to provide continuity and familiarity with the firm’s requirements.
Improved Operational Efficiency
With compliance work running reliably in the background, partners can dedicate more attention to business development and client relationships.
6. Key Results and Business Outcomes
The partnership demonstrates how a flexible outsourcing model can grow into a long-term operational arrangement.
