Kill Bill vs SolidInvoice: at a glance
What is Kill Bill?
Kill Bill keeps two release lines alive with small invoice-template changes.
Kill Bill ships on two lines: 0.25.x tags with no published notes, and 0.24.x releases that list small changes. Recent 0.24 work is about invoices: shared tenant branding (logo, company info, colours) in the HTML invoice generator, a revert of a branding template key, and partial-locale support for invoice and catalog translations.
What is SolidInvoice?
SolidInvoice finally shipped the 3.0 it spent a year staging in alphas and betas.
After more than twelve months of alpha and beta releases, SolidInvoice 3.0 landed in June with the accumulated work of that cycle: email verification, Google OAuth, two-factor authentication, real user profiles, flat-rate tax support and a Meilisearch-backed search layer. Underneath it, the project moved onto a shared platform config and pulled trial and SaaS logic into an external bundle. The 2.3 line ran in parallel the whole time, absorbing security backports.
Kill Bill vs SolidInvoice: editorial side-by-side
Kill Bill
5.0FINANCE
Kill Bill keeps two release lines alive with small invoice-template changes.
◆ Current state
Kill Bill ships on two lines: 0.25.x tags with no published notes, and 0.24.x releases that list small changes. Recent 0.24 work is about invoices: shared tenant branding (logo, company info, colours) in the HTML invoice generator, a revert of a branding template key, and partial-locale support for invoice and catalog translations.
◆ Where it's heading
The visible feature work is per-tenant invoice presentation, with branding and localisation becoming configurable rather than hard-coded. The 0.25 line ships regularly but its notes are bare Maven tags, so its direction can't be read from the entries.
◆ Prediction
More invoice-presentation and localisation changes on 0.24.x are likely; what 0.25.x is building toward isn't visible in the entries.
SolidInvoice
0.0FINANCE
SolidInvoice finally shipped the 3.0 it spent a year staging in alphas and betas.
◆ Current state
After more than twelve months of alpha and beta releases, SolidInvoice 3.0 landed in June with the accumulated work of that cycle: email verification, Google OAuth, two-factor authentication, real user profiles, flat-rate tax support and a Meilisearch-backed search layer. Underneath it, the project moved onto a shared platform config and pulled trial and SaaS logic into an external bundle. The 2.3 line ran in parallel the whole time, absorbing security backports.
◆ Where it's heading
Two threads run through this changelog. The visible one is identity and account management catching up to what users expect from a billing app — signup verification, OAuth, 2FA, self-serve company deletion. The less visible one is the codebase being restructured around reusable solidworx platform components with Sentry and Prometheus instrumentation, which is the shape of a project preparing to run itself as a hosted service rather than only as a download.
◆ Prediction
With 3.0 out and 3.0.1 already repairing the upgrade migration path, the near-term work is likely more 3.0.x stabilization for people coming off 2.3 rather than new features.
