How to Set Up Management Reporting in Xero + Fathom Easily

Good management accounts don’t happen by accident – they’re built through clear structure, consistent coding, and effective reporting tools. If you’re wondering how to set up management reporting in Xero + Fathom, this article walks you through a practical, step-by-step setup for transforming Xero and Fathom into a powerful management reporting system.


A well-structured chart of accounts should distinguish between:

  • Direct costs (materials, subcontractors, delivery)
  • Indirect costs (rent, admin, software, salaries)

Allocate indirect costs logically e.g. based on revenue, headcount or square footage.

Keep it simple but meaningful – clarity beats complexity.


Use tracking categories to segment data by:

  • Service lines
  • Product types
  • Projects
  • Departments
  • Geographical locations

Apply categories consistently to sales invoices, purchase bills, and expenses.


Once linked:

  • Data updates automatically
  • You can build custom dashboards
  • Reports can be tailored to stakeholders

You can generate tailored, repeatable reporting packs. As well as the usual balance sheet and P&L, you could include:

  • P&L by revenue stream
  • Margin analysis
  • Monthly trend graphs
  • Budget vs. actual
  • Customer or product profitability
  • Key financial ratios (e.g. gross margin % or debtor days)

Use Fathom to show:

  • Revenue trends
  • Gross margin comparisons
  • KPI performance over time

Visual insights drive better conversations.


Model:

  • Cash flow
  • Pricing changes
  • Hiring
  • Contract wins or losses
  • Best/worst-case scenarios

This becomes essential during fundraising or strategic planning.


Numbers tell you what happened.
Commentary tells you why – and what to do next.


Fathom allows branded, board-ready reporting in a few clicks.


  • Reconcile Xero regularly and ensure consistent coding. Set up a bank feed in Xero and bank rules for recurring transactions which allows you to reconcile with a single click
  • Upload budgets into Fathom for powerful variance analysis. You can link your budget to the forecasting tool to build a P&L forecast directly from your budget
