InvoicePlane vs Stigg: 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 Stigg?
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.

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.
Stigg
6.3FINANCE
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
◆ Current state
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.
◆ Where it's heading
Credits have become Stigg's main pricing unit, and the product is adapting them to AI workloads whose cost isn't known up front. Reserve and settle, together with the governance SDK, turns the entitlements engine into a spending control for agents.
◆ Prediction
Expect the governance SDK to use reservations directly for agent limits, and more reporting on reserved versus settled usage.
