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 brings contract management and overages GA — usage-based billing gets enterprise contract depth.
Stigg is a billing and entitlement platform for SaaS companies. Recent releases have focused on the enterprise monetization stack: overages for metered features and credits are now generally available, Contract Management (beta) pulls custom contract terms out of signed PDFs and CRM notes into a structured system, unified Eurozone pricing simplifies multi-country pricing, and Edge API support in the Go SDK reduces entitlement check latency. The platform is adding both the breadth of billing models and the depth of enterprise contract handling.

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 brings contract management and overages GA — usage-based billing gets enterprise contract depth.
◆ Current state
Stigg is a billing and entitlement platform for SaaS companies. Recent releases have focused on the enterprise monetization stack: overages for metered features and credits are now generally available, Contract Management (beta) pulls custom contract terms out of signed PDFs and CRM notes into a structured system, unified Eurozone pricing simplifies multi-country pricing, and Edge API support in the Go SDK reduces entitlement check latency. The platform is adding both the breadth of billing models and the depth of enterprise contract handling.
◆ Where it's heading
The direction is full enterprise billing lifecycle coverage — from initial pricing and entitlements through contract-specific terms, metered overages, and Salesforce/Zuora integration. The Usage Governance Skill (AI coding assistant context) signals investment in developer experience for complex billing implementations. Stigg is moving from 'entitlement enforcement' toward 'billing infrastructure as code'.
◆ Prediction
Contract Management beta going GA is the likely near-term milestone. The Salesforce integration's unlimited entitlement support and Zuora metadata suggestions suggest deeper CRM/billing-system parity is coming, potentially with automated contract-to-entitlement provisioning.
