How Segmented Management Accounts Boost Profitability

Understanding your numbers properly starts with clarity – and that’s exactly what segmented management accounts provide. In this case study, we explore how a business like Eastern Precision Ltd could use segmentation to uncover hidden margin issues, challenge assumptions, and make strategic decisions that materially improve profitability.


Big, blended numbers can hide the truth – and that’s where problems start. When revenue streams and costs aren’t broken down, loss‑making work can quietly sit behind averages. This example shows how better reporting unlocks insight, control, and performance.


  • Company: Eastern Precision Ltd
  • Industry: Precision engineering
  • Work Type: High-value aerospace and automotive contracts
  • Challenge: Management accounts grouped all revenue and costs together, showing an average margin of 26%.

Leadership assumed all contracts performed similarly. They didn’t.


Aggregated reporting masked major differences among contracts. Pricing and resource allocation were based on incomplete data, and one long-standing contract was eroding overall profitability.


After implementing segmented management accounts using Xero and Fathom:

  • True margins became visible: A “healthy” average margin masked major variation.
  • Alpha contracts: 38–43% margins
  • Beta contracts: 18–24% margins
  • Gamma contracts: 4–9% margins – pulling overall performance down

The overall margin looked stable only because Gamma’s poor performance offset Alpha’s strength.


  • Increased pricing for future Beta-type contracts by 15%
  • Declined renewal of Gamma-type contracts
  • Redeployed skilled staff from Gamma to Alpha-type work
  • Negotiated supplier discounts on Beta-type contracts

Within nine months:

  • Overall margin improved from 27% to 34%
  • Annual profitability increased by £0.3m
  • Leadership gained confidence for future fundraising discussions

Segmentation didn’t just improve reporting – it improved the business.
