Introduction...

Numberwork Services is a modern bookkeeping and payroll practice based in Newbury, founded and led by Fiona Jones. With a strong focus on delivering timely and accurate financial data, Fiona and her team serve primarily VAT-registered, B2B limited companies in the professional services sector.

As the practice has grown, so has the need to maintain high-quality standards across an expanding client base. To achieve this, Fiona and her team turned to Xenon Connect.

The Challenge...

Prior to adopting Xenon Connect, Numberwork Services relied heavily on manual checks to ensure bookkeeping data was complete and accurate. This process was time-consuming and prone to human oversight – issues would often surface only when preparing VAT returns or conducting in-depth client reviews.

With plans to scale and a commitment to high standards, Fiona needed a smarter solution.

“We pride ourselves on providing timely, accurate data. It's really important to me that the data we provide to our clients is accurate because they are using that information to make decisions.”

The Solution...

Fiona discovered Xenon Connect at the Institute of Certified Bookkeepers’ Bookkeepers Summit. Intrigued by the platform’s data health dashboard, she decided to adopt it to enhance her firm’s quality control processes.

Today, Xenon Connect is an integral part of the Numberwork Services workflow. Fiona’s team uses it daily to run bookkeeping checks across all client files. The tool acts as an “extra pair of eyes,” helping staff proactively identify and resolve errors before Fiona even needs to review the work.

Key Benefits...

  • Bookkeeping Data Health Score
    The practice uses Xenon’s visual health score to quickly assess the overall quality of each client’s data. This metric has become a key internal KPI for Fiona.

  • Error Prevention and Time Savings
    With automated checks, the team catches issues earlier – before VAT returns or client reports – saving hours of manual review.

  • Support for KPI Tracking and Growth Management
    Fiona uses Xenon Connect to monitor bookkeeping quality across the practice and to assess workload growth per client by tracking transaction volumes – an invaluable feature for client repricing decisions.

“Just being able to look at transaction counts for all clients at a high level is invaluable. I can easily track whether there's been growth in that client's business, and therefore am I charging them correctly now that I am doing more work.”

Conclusion...

For Fiona Jones and her team, Xenon Connect has become more than a tool – it’s an extension of the team itself.

“If I could describe Xenon Connect in a few words, it would be: my extra resource.”

'Xenon Connect - The Future'

‘A very useful, powerful add-on to identify matters requiring different levels of attention in Xero accounting files.

The client overall panorama is good as you can compare how different clients manage their accounts and can then drill down in specific areas.’
