InvoicePlane vs WP Simple Pay
A side-by-side editorial comparison of InvoicePlane and WP Simple Pay — release velocity, themes, recent moves, and the top alternatives to consider.
InvoicePlane vs WP Simple Pay: 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 WP Simple Pay?
WP Simple Pay made recurring payments free, betting reach beats gating the marquee feature.
The releases track Stripe's own surface: 4.16 added region-specific local payment methods, 4.13 Stripe compliance controls and required-price options, and older versions layered ACH, Bacs, GrabPay, and multi-item checkout. The standout is 4.14, which removed the paywall on recurring subscription payments. The newest entry is October 2025, so the feed is somewhat stale.

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.
WP Simple Pay
0.0FINANCE
WP Simple Pay made recurring payments free, betting reach beats gating the marquee feature.
◆ Current state
The releases track Stripe's own surface: 4.16 added region-specific local payment methods, 4.13 Stripe compliance controls and required-price options, and older versions layered ACH, Bacs, GrabPay, and multi-item checkout. The standout is 4.14, which removed the paywall on recurring subscription payments. The newest entry is October 2025, so the feed is somewhat stale.
◆ Where it's heading
WP Simple Pay is competing on Stripe coverage and, with 4.14, on access, trading a premium feature gate for wider adoption. The direction is being the default no-code Stripe form plugin rather than an upsell ladder.
◆ Prediction
Expect continued fast-following of Stripe payment-method and compliance additions; whether the free-subscriptions move shifts monetization elsewhere isn't visible in these entries.
