InvoiceShelf vs Kill Bill: at a glance
What is InvoiceShelf?
InvoiceShelf 3.0 alphas add bills and suppliers, moving it from invoicing into payables.
Five InvoiceShelf 3.0 alphas shipped in five days. alpha.11 added purchasing (suppliers, bills, supplier credits, payments and refunds) and patched two unauthenticated PHP remote code execution flaws in the Docker image. Later alphas added module API 1.4 with bundled dependencies, EN 16931 e-invoicing with ZUGFeRD / Factur-X hybrid PDFs, a notification bell with automatic payment reminders, and an iOS app headed for TestFlight.
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.

◆ Current state
Five InvoiceShelf 3.0 alphas shipped in five days. alpha.11 added purchasing (suppliers, bills, supplier credits, payments and refunds) and patched two unauthenticated PHP remote code execution flaws in the Docker image. Later alphas added module API 1.4 with bundled dependencies, EN 16931 e-invoicing with ZUGFeRD / Factur-X hybrid PDFs, a notification bell with automatic payment reminders, and an iOS app headed for TestFlight.
◆ Where it's heading
3.0 is turning InvoiceShelf from an invoice generator into a small-business accounting app: payables next to receivables, EU-compliant e-invoices, a module ecosystem, and native mobile apps. The pace suggests the team is finishing features before a beta rather than stabilizing.
◆ Prediction
Expect more alphas filling in accounting pieces and modules built on API 1.4/1.5, with the iOS app appearing on TestFlight; the entries don't show a beta date.
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.
