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 its billing engine on a slow, reliability-first maintenance cadence.
Kill Bill, the open-source subscription-billing platform, is in steady maintenance mode. The active 0.24.x line is a stream of bug fixes, dependency updates, and invoice-processing reliability work, while a 0.25.x branch has opened with point releases that so far ship as bare release-plugin tags without published notes. Nothing here changes the capability surface; the focus is correctness and operational robustness of billing runs.

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
5.0FINANCE
Kill Bill keeps its billing engine on a slow, reliability-first maintenance cadence.
◆ Current state
Kill Bill, the open-source subscription-billing platform, is in steady maintenance mode. The active 0.24.x line is a stream of bug fixes, dependency updates, and invoice-processing reliability work, while a 0.25.x branch has opened with point releases that so far ship as bare release-plugin tags without published notes. Nothing here changes the capability surface; the focus is correctness and operational robustness of billing runs.
◆ Where it's heading
The project is hardening the parts operators feel most: invoice failure handling, lock and retry behavior, and logging around aborted runs. The parallel 0.25.x line suggests the next feature-bearing release is being staged, but the visible changes remain incremental. Expect continued small releases stabilizing invoicing before 0.25.x carries anything user-facing.
◆ Prediction
Likely more 0.24.x/0.25.x point releases in the same vein — dependency bumps and invoice-reliability fixes — with 0.25.0's substantive changes only becoming clear once release notes accompany the tags.
