  • From preparing board packs to connecting different ledgers, the right software should fit the way your finance team works. We look at the practical differences between Joiin and Fathom to help you choose.

    Joiin and Fathom both offer financial reporting, consolidation, forecasting and AI commentary. The differences become clearer beyond the reports themselves: connecting multiple accounting platforms, building report packs, analysing results, automating finance workflows with AI and sharing data across your business.

     

    Joiin brings these capabilities together in one platform. Joiin Intelligence goes beyond AI commentary, with advanced AI agents that help finance teams complete tasks and uncover insights. Connections to Excel, BI tools and MCP-enabled applications make it easier to access, analyse and share financial data across your business. Both Joiin and Fathom offer 3 way forecasting.

     

    Here’s how they compare.

    AI that helps prepare the report, too

    Joiin Intelligence is our AI layer for exploring financial and operational results and carrying out reporting tasks.

     

    Ask a question about performance, follow up on a movement or draft commentary for a Report Pack. With AI agents, you can also describe work you need completed, including:

     

    • Building reports and Report Packs.
    • Helping organise your chart of accounts and merge duplicate accounts.
    • Setting up intercompany eliminations.
    • Checking financial information for issues that need attention.

     

    These capabilities extend AI into the preparation work behind recurring reporting. Joiin’s published agent workflow includes confirmation, verification and traceability controls.

     

    Fathom’s Commentary Writer focuses on drafting report narrative. It uses business context, report context and selected reporting components, with attribution that lets users inspect the figures behind the commentary.

     

    And the calculations in Joiin remain within our established reporting framework. The agents run reports and retrieve results through that framework; the language model does not generate the underlying financial accounts.

     

    But AI commentary still needs review. Your team brings the business context, checks the explanation and decides what to share.

    Consolidate without changing every accounting system

    Growing groups often inherit different ledgers through acquisitions, international expansion or local accounting requirements.

     

    Joiin connects Xero, QuickBooks Online, Intuit Enterprise Suite, Sage, MYOB, FreeAgent, Zoho Books, Pennylane, Puzzle and Fortnox, alongside spreadsheet uploads.

    A UK parent on Xero, a US entity on QuickBooks and a Swedish subsidiary on Fortnox can report together in Joiin while keeping their source accounting systems.

     

    Chart of accounts mapping brings different structures into a shared reporting layout. Eliminations remove internal activity from group results, while multi-currency reporting supports entities operating in different currencies.

     

    Joiin supports complex group structures, multiple accounting systems and currencies, without the same consolidation limits. With flexible entity-based pricing, unlimited users and reports, businesses can scale their financial reporting as they grow.

    Fathom also supports mixed-system consolidation and intercompany eliminations. Its published limits are 300 entities within a single-currency group and 50 within a multi-currency group. Consolidated groups carry no additional charge, with no cap on the number of groups created.

     

    Build reporting around your business

    Joiinr Report Packs combine financial reports, charts and commentary in one document. Customise account groupings, formulas and layouts, add your branding and tailor the content for boards, clients or management teams.

     

    Dynamic dates keep recurring reports aligned with the reporting period. Schedule weekly or monthly distribution, present live or share a secure read-only link. Cell comments let you explain individual results, with comments included as numbered notes in PDF output.

     

    Non-financial data adds context: headcount alongside staff costs, store numbers alongside revenue or production volumes alongside operating expenses. Custom KPIs connect those measures across reports and dashboards.

     

    Fathom Reporting also provides branded, scheduled reporting and financial and non-financial KPIs. Its dedicated benchmark groups, ranking tools and profitability analysis support advisers comparing businesses and exploring performance.

    Forecasting: compare how you build and adjust plans

    Both products offer three-way forecasting, linking profit and loss, balance sheet and cash flow.

     

    In Joiin, forecasts start from actual financial data for a company or group. Set rules using trends, growth assumptions and drivers, or describe changes in plain English.

     

    Ask Joiin to increase revenue from April or add a recurring monthly cost, then inspect and adjust the resulting forecast rules. Forecasts extend up to 60 months, with forecast-versus-actual comparisons as results come in.

     

    Fathom provides dedicated scenarios and microforecasts. These model individual decisions, projects or events separately from the baseline, such as hiring someone or buying equipment.

     

    Joiin supports natural-language forecast creation and updates. Fathom provides specialised tools for organising scenarios and project-level assumptions.

    Use your financial data beyond the reporting application

    Your existing Excel models do not have to be rebuilt. Joiin’s Excel Add-In brings live consolidated figures into workbooks, keeping your formulas and models in place while you refresh the data.

     

    Fathom supports Excel imports and report exports, serving a different workflow from a connected workbook.

     

    Joiin Connect provides API connections for Power BI, Tableau and data warehouses, while our Zapier integration supports wider automation. Fathom documents indirect Zapier workflows through Google Sheets.

     

    And Joiin’s MCP server connects compatible AI assistants, including Claude, to authorised reporting tools and data. Ask questions and run reports from the assistant, with access governed by your Joiin permissions.

    Joiin offers Core, Pro and Max, priced by company count. Core includes single-currency reporting and consolidation. Pro adds forecasting, multi-currency, non-financial data, the Excel Add-In and AI agents. Max adds API, Zapier and MCP connections, plus advanced exchange rate controls.

     

    Unlimited users, reports and clients are included on every Joiin plan. Fathom offers company-based Pro plans, Enterprise quotes and a separate Portfolio subscription with a smaller feature set.
