What is Kill Bill?
Kill Bill grinds out invoice-reliability fixes on a mature 0.24.x line.
Kill Bill remains a mature open-source subscription-billing engine in steady maintenance on its 0.24.x line. Recent releases concentrate on invoice-processing reliability — retries, account parking on unrecoverable failures, and uniform failure logging — plus catalog and payment-plugin bug fixes. The 0.25.0 tag was cut in late June but shipped with no release notes, so its scope is unclear.
What is Payhawk?
Payhawk builds out travel management on top of its spend platform
Payhawk's releases show two pushes. First, Payhawk Travel is maturing into a full T&E offering, admin booking on behalf of employees, travel allowances in policy, baggage selection and smart bundles, and in-app trip changes. Second, its EMI banking infrastructure keeps widening: GBP accounts for EU customers, CHF and more holdable currencies, German open-banking top-ups, end-to-end bulk payments, and a new layered payment-fraud-prevention system.

◆ Current state
Kill Bill remains a mature open-source subscription-billing engine in steady maintenance on its 0.24.x line. Recent releases concentrate on invoice-processing reliability — retries, account parking on unrecoverable failures, and uniform failure logging — plus catalog and payment-plugin bug fixes. The 0.25.0 tag was cut in late June but shipped with no release notes, so its scope is unclear.
◆ Where it's heading
The direction is hardening, not expansion: most point releases are bug fixes and dependency updates rather than new capability. Invoice failure handling has recurred across the last several releases, pointing to an effort to make billing runs resilient to bad plugin and catalog states rather than fail silently. The parallel 0.25.0 tag hints a new minor line is being prepared, but there is no visible feature content yet.
◆ Prediction
Expect continued 0.24.x point releases on the same bug-fix cadence; whether 0.25.0 carries real new features will not be clear until it ships with actual release notes.

◆ Current state
Payhawk's releases show two pushes.

Second, its EMI banking infrastructure keeps widening: GBP accounts for EU customers, CHF and more holdable currencies, German open-banking top-ups, end-to-end bulk payments, and a new layered payment-fraud-prevention system.
◆ Where it's heading
Payhawk is converging spend management, multi-currency banking, and travel into one finance platform, owning more of where corporate money moves and how it is controlled. The fraud-prevention and master-data-sync work signals enterprise-grade hardening to support that breadth.
◆ Prediction
Expect Travel to keep expanding toward parity with dedicated TMCs and more currency and market coverage on the EMI rails.
