InvoiceShelf vs Kill Bill: at a glance
What is InvoiceShelf?
InvoiceShelf 3.0 alphas let Claude, ChatGPT and Cursor draft and send invoices.
InvoiceShelf is pushing 3.0 through public alphas at a rate of several a week, each marked not for production. Alpha.5 added an MCP server so AI assistants can read, draft and send documents with the connecting user's permissions. Later alphas add role presets, user administration for the super admin, official modules on managed installs and a Docker image that runs on a read-only filesystem, alongside a steady stream of security fixes.
What is Kill Bill?
Kill Bill's 0.25 line ships tags with no notes while 0.24 does the actual work
Kill Bill is publishing two lines that behave nothing alike. The 0.25 releases — 0.25.1 through 0.25.4 across July and August — carry a single line of body text apiece, the maven-release-plugin's tag-copy message, with no changelog at all. The 0.24 line carries structured notes with issue references, and it is where the recent user-facing work sits: shared tenant branding for HTML invoices in 0.24.20, then a revert of part of it in 0.24.21 five days later.

InvoiceShelf 3.0 alphas let Claude, ChatGPT and Cursor draft and send invoices.
◆ Current state
InvoiceShelf is pushing 3.0 through public alphas at a rate of several a week, each marked not for production. Alpha.5 added an MCP server so AI assistants can read, draft and send documents with the connecting user's permissions. Later alphas add role presets, user administration for the super admin, official modules on managed installs and a Docker image that runs on a read-only filesystem, alongside a steady stream of security fixes.
◆ Where it's heading
3.0 is turning a single-company invoicing app into something a hosting provider can run for many customers: role presets across companies, provider-controlled module installs, a separate customer-portal host and a locked-down container. The security fixes (guessable document links, SSRF through mail settings, a setup token that acted as super-admin) show the multi-tenant hardening is still catching up with the feature work.
◆ Prediction
Expect more alphas that close security issues and fill out hosted-provider controls before a beta; the entries show no beta date.

Kill Bill's 0.25 line ships tags with no notes while 0.24 does the actual work
◆ Current state
Kill Bill is publishing two lines that behave nothing alike. The 0.25 releases — 0.25.1 through 0.25.4 across July and August — carry a single line of body text apiece, the maven-release-plugin's tag-copy message, with no changelog at all. The 0.24 line carries structured notes with issue references, and it is where the recent user-facing work sits: shared tenant branding for HTML invoices in 0.24.20, then a revert of part of it in 0.24.21 five days later.
◆ Where it's heading
Reading the 0.24 line alone, the theme is invoice-generation robustness continuing from 0.24.18's error handling, retries and account parking, into 0.24.20's branding refactor. The August 12 revert of the template branding key suggests that refactor is not settled. What the 0.25 line contains is genuinely unknown from this feed — the tags exist, the notes do not.
◆ Prediction
Expect the tenant-branding work to return in a corrected form on the 0.24 line, since the revert removed the key rather than the surrounding refactor. Whether 0.25 is a development line or a release line is not something these entries answer.
