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 Sequence?
Sequence opens its billing data to AI agents while deepening payments and automation
Sequence is a billing and revenue-automation platform whose recent releases cluster around three areas: payment-rail integrations (GoCardless direct debit, Sphere tax), workflow automation (visual Automations with Watchtower review, Dunning reminder sequences), and finance-team reporting (revenue waterfall export, credit-note detail). Its newest move exposes all of this billing data to AI agents over MCP.

Kill Bill
5.0FINANCE
Kill Bill grinds out invoice-reliability fixes on a mature 0.24.x line.
◆ 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.

Sequence opens its billing data to AI agents while deepening payments and automation
◆ Current state
Sequence is a billing and revenue-automation platform whose recent releases cluster around three areas: payment-rail integrations (GoCardless direct debit, Sphere tax), workflow automation (visual Automations with Watchtower review, Dunning reminder sequences), and finance-team reporting (revenue waterfall export, credit-note detail). Its newest move exposes all of this billing data to AI agents over MCP.
◆ Where it's heading
The product is becoming programmable and agent-accessible. Automations and Dunning turn billing operations into configurable, reviewable workflows; the payment integrations broaden how money moves; and Sequence MCP lets external AI agents query invoices, schedules, customers, pricing, and revenue in natural language. The direction is billing as an API-and-agent surface, not just a UI.
◆ Prediction
Expect Sequence to extend MCP from read-style querying toward agent-driven actions, and to keep adding automation templates and payment/tax integrations.
