InvoicePlane vs Kill Bill: at a glance
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.
What is Kill Bill?
Kill Bill keeps hardening invoice reliability on its mature 0.24 line
Kill Bill is in steady maintenance on the 0.24.x branch. Recent releases concentrate on invoice-failure handling — retries, account parking, and uniform WARN logging — plus catalog and subscription edge-case fixes. This is reliability work on a mature open-source billing core.

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.
Kill Bill
2.5FINANCE
Kill Bill keeps hardening invoice reliability on its mature 0.24 line
◆ Current state
Kill Bill is in steady maintenance on the 0.24.x branch. Recent releases concentrate on invoice-failure handling — retries, account parking, and uniform WARN logging — plus catalog and subscription edge-case fixes. This is reliability work on a mature open-source billing core.
◆ Where it's heading
The arc is operational robustness rather than new features: making invoice processing fail predictably, tightening lock-failure retries, and improving observability. A platform whose users run it as critical billing infrastructure rewards exactly this.
◆ Prediction
Expect continued 0.24.x point releases focused on invoicing/catalog correctness and logging, with no major architectural shift in the near term.
