Fathom
What It Does
Fathom is a financial reporting and analysis tool that connects to your accounting software (Xero, QuickBooks, or MYOB) and transforms your numbers into visual reports, KPI dashboards, budgets vs actuals, cash flow forecasts, and management reports that you can actually understand and act on.
The problem Fathom solves is the gap between raw accounting data and useful business intelligence. Xero tells you what happened. Fathom tells you what it means, how you’re trending, and where you should focus. It calculates financial ratios, highlights anomalies, compares performance against budgets and prior periods, and produces polished reports you can share with investors, banks, or your board.
For UK businesses that want to be data-driven but don’t have a finance director, Fathom provides the analytical layer that turns bookkeeping data into strategic insight.
Who It’s For
Growing businesses that need better financial visibility: If your monthly accounts are a set of Xero reports that you glance at and file, Fathom makes that data useful. Visual dashboards, trend analysis, and KPI tracking turn numbers into decisions.
Businesses with investors, board members, or bank relationships: Fathom’s report builder creates polished, professional management reports — the kind you’d normally pay a finance director or consultant to produce.
Accountancy practices serving SME clients: Many UK accountants use Fathom to provide advisory services on top of compliance work. If your accountant uses Fathom, you may already have access to its reports.
Not ideal for: Very small businesses with simple finances (your Xero dashboard may be sufficient), businesses not using cloud accounting software, or those needing real-time operational dashboards (Fathom refreshes periodically from your accounting data).
UK-Specific Notes
Fathom prices in GBP, starting at approximately £38/month for a single company. This positions it as an affordable alternative to hiring a part-time finance director.
UK financial metrics and benchmarks are well-supported. Fathom calculates standard UK financial ratios and lets you benchmark against industry standards. Management reports follow familiar UK formats.
Xero integration is the primary connection for UK users, and it’s excellent — Fathom pulls your complete financial data and updates automatically. The depth of data available through the Xero connection means reports are comprehensive from day one.
GDPR compliance is handled through data processing agreements. Financial data is sensitive, so review Fathom’s security credentials — they hold SOC 2 certification and encrypt data at rest and in transit.
Key Features
Setup & Complexity
Easy — Self-serve. Connect to Xero, and Fathom imports your financial data automatically. Your first dashboard is ready within minutes. Building custom reports takes 30-60 minutes using the drag-and-drop builder.
The main investment is in thinking about which KPIs matter to your business and configuring budgets for comparison. Fathom provides templates and guidance, but the strategic thinking is yours.
If you work with an accountant who uses Fathom, they can set up your reports and dashboards as part of their advisory service — often the fastest route to getting value.

How We’d Use It
Month 1: Connect Fathom to Xero and explore the automatic dashboards. Identify the 5-8 KPIs that matter most to your business. Set up your first management report template and share it with your leadership team or board.
Month 2: Enter your annual budget and start tracking actual performance against plan. Configure alerts for metrics that move outside acceptable ranges. Use the cash flow forecast to anticipate any tight periods over the next 3-6 months.
Month 3: Refine your reports based on what’s actually driving decisions. Remove vanity metrics, add operational KPIs, and start the habit of a monthly management report review. If you have investors or bank covenants, customise a report specifically for their requirements.

Our Verdict
Fathom is the analytical upgrade that every growing UK business using Xero should consider. It turns your accounting data from a record of what happened into a tool for understanding what’s happening and what’s likely to happen next. The management reports alone are worth the subscription.
Buy if: You use Xero, your business is growing, and you want better financial visibility without hiring a finance director. The monthly cost is insignificant compared to the decisions it helps you make better.
Skip if: Your Xero dashboard gives you everything you need, your business finances are very simple, or you already have a finance director providing this analysis.
Bottom line: Fathom is one of those tools that makes you realise what you’ve been missing. Once you have visual dashboards, budget tracking, and cash flow forecasts, going back to raw Xero reports feels like going back to candlelight. Essential for any UK business that wants to make decisions based on data rather than gut feel.
