What is Fathom?
Fathom adds FreeAgent and refines its Pro reports — steady iteration without directional pivots.
Fathom is a financial reporting and forecasting tool for accountants and advisory firms. The most recent product addition in the input is the FreeAgent integration (January 2026), continuing a steady pattern of bringing new accounting platforms into the same workflow. Earlier 2025 work focused on report flexibility — embedded images and PDFs in Pro reports — and forecast operations like forecast snapshots that enable actual-vs-forecast reporting. The recent feed is also heavy with customer stories and educational content rather than fresh product releases.
What is InvoicePlane?
InvoicePlane's beta cycle is mostly security hardening and PHP modernization
InvoicePlane is moving through a slow beta cadence on the 1.6/1.7 lines. The substance is security improvements credited to outside researchers and PHP 8.2+ compatibility — keeping a long-lived open-source invoicing tool current rather than expanding it.
Fathom vs InvoicePlane: editorial side-by-side
Fathom
5.0FINANCE
Fathom adds FreeAgent and refines its Pro reports — steady iteration without directional pivots.
◆ Current state
Fathom is a financial reporting and forecasting tool for accountants and advisory firms. The most recent product addition in the input is the FreeAgent integration (January 2026), continuing a steady pattern of bringing new accounting platforms into the same workflow. Earlier 2025 work focused on report flexibility — embedded images and PDFs in Pro reports — and forecast operations like forecast snapshots that enable actual-vs-forecast reporting. The recent feed is also heavy with customer stories and educational content rather than fresh product releases.
◆ Where it's heading
Within the visible product entries, Fathom is widening accounting-platform coverage (FreeAgent joins Xero, QBO, Sage and others) and gradually upgrading the Pro report surface — saved views, downloadable insights, embedded files, forecast snapshots. There's no sign of a directional pivot in the input; the cadence reads as a mature product steadily extending its existing surfaces, with marketing weight increasingly on customer stories rather than feature launches.
◆ Prediction
Expect continued accounting-platform additions (the Sage 50 import in beta from late 2024 will likely graduate at some point) and more Pro-tier report-flexibility work. Without a clear directional move in the input, the most likely next year looks like more of the same steady cadence.
InvoicePlane
0.0FINANCE
InvoicePlane's beta cycle is mostly security hardening and PHP modernization
◆ Current state
InvoicePlane is moving through a slow beta cadence on the 1.6/1.7 lines. The substance is security improvements credited to outside researchers and PHP 8.2+ compatibility — keeping a long-lived open-source invoicing tool current rather than expanding it.
◆ Where it's heading
The trajectory is maintenance and modernization: security patches, runtime compatibility, and release-candidate hygiene. There is little new user-facing capability; the value is keeping a self-hosted billing app safe and installable on modern stacks.
◆ Prediction
Expect 1.7.2 to reach stable after the beta security work settles, with PHP-version support and vulnerability fixes as the headline.
