InvoicePlane vs FreeAgent
A side-by-side editorial comparison of InvoicePlane and FreeAgent — release velocity, themes, recent moves, and the top alternatives to consider.
InvoicePlane vs FreeAgent: at a glance
What is InvoicePlane?
InvoicePlane's 1.7.2 is a mass security remediation, still working through its release candidates.
InvoicePlane is a self-hosted PHP invoicing and quoting application. The 1.7.2 line, now at its second release candidate, is dominated by security remediation: roughly thirty researchers are credited across the beta and RC notes for responsibly disclosed vulnerabilities, with severity, CVSS and GHSA advisories held back until the final release. The RC also warns that installations running custom invoice and quote templates must take manual steps before upgrading.
What is FreeAgent?
FreeAgent is expanding beyond freelancers into landlord-specific accounting with automated rental statement processing.
FreeAgent has spent the past year layering Making Tax Digital compliance tooling—early access in September 2025, practice management tools in December, Self Assessment filing for 2025/26 in April 2026. Alongside that compliance track, it shipped a Pleo expense management integration and Fathom analytics connector to round out the financial workflow. The June 2026 launch of FreeAgent for Landlords marks the first deliberate product segment expansion beyond its core freelancer and small-business base.

InvoicePlane
5.0FINANCE
InvoicePlane's 1.7.2 is a mass security remediation, still working through its release candidates.
◆ Current state
InvoicePlane is a self-hosted PHP invoicing and quoting application. The 1.7.2 line, now at its second release candidate, is dominated by security remediation: roughly thirty researchers are credited across the beta and RC notes for responsibly disclosed vulnerabilities, with severity, CVSS and GHSA advisories held back until the final release. The RC also warns that installations running custom invoice and quote templates must take manual steps before upgrading.
◆ Where it's heading
The project has spent this cycle absorbing an unusually large volume of external vulnerability reports while simultaneously modernising the platform — PHP 8.2 compatibility arrived on the 1.7.0 branch, and Stripe and PayPal were reintroduced at 1.7.2 beta 1 after having been absent. The decision to withhold advisory details until 1.7.2 goes final is a deliberate disclosure posture, meaning the true scope of what these releases fix is not yet public. Release notes here are dominated by hashes and contributor credits rather than change detail.
◆ Prediction
The final 1.7.2 release and the simultaneous publication of the security advisories are the clear next step, given RC 2 is described as working toward it. Whether further RCs intervene depends on what testing surfaces.
FreeAgent
0.0FINANCE
FreeAgent is expanding beyond freelancers into landlord-specific accounting with automated rental statement processing.
◆ Current state
FreeAgent has spent the past year layering Making Tax Digital compliance tooling—early access in September 2025, practice management tools in December, Self Assessment filing for 2025/26 in April 2026. Alongside that compliance track, it shipped a Pleo expense management integration and Fathom analytics connector to round out the financial workflow. The June 2026 launch of FreeAgent for Landlords marks the first deliberate product segment expansion beyond its core freelancer and small-business base.
◆ Where it's heading
FreeAgent is running two parallel tracks: deepening UK tax compliance (MTD, CIS, Self Assessment) for existing users, and opening a new market segment with a purpose-built landlord product. Automated rental statement parsing—categorising letting agent statements into structured entries—is the technical differentiator for the landlord track, not just a UI rename. If the landlord product gains traction, FreeAgent's distribution through NatWest's SME banking network becomes a significant acquisition channel.
◆ Prediction
The next move is likely native HMRC MTD for Property Income submission from within the landlord product, closing the end-to-end compliance loop for landlord customers who currently need a separate tool to file.
