What is Kolleno?
Kolleno is turning AR collections into an AI-run operations layer.
Kolleno is an accounts-receivable and collections platform that has spent the last two quarters wiring AI into the core finance workflow rather than bolting it on. Recent releases moved from AI-detected promises to pay and remittance reading toward reconciliation logic, performance dashboards, and now a full rebuild of how teams manage customer queries.
What is Kill Bill?
Kill Bill cuts a new 0.25 line after a long 0.24.x reliability run
Kill Bill, the open-source subscription-billing platform, ships on a slow, deliberate cadence. The just-tagged 0.25.0 opens a new minor line, but its feed entry carries only the maven-release-plugin boilerplate, so the substantive changelog isn't visible in the source. The preceding 0.24.x series was steady reliability work: invoice failure handling (retries, account parking, uniform logging), multi-tenant query indices, and operability improvements like config-source visibility.

Kolleno is turning AR collections into an AI-run operations layer.
◆ Current state
Kolleno is an accounts-receivable and collections platform that has spent the last two quarters wiring AI into the core finance workflow rather than bolting it on. Recent releases moved from AI-detected promises to pay and remittance reading toward reconciliation logic, performance dashboards, and now a full rebuild of how teams manage customer queries.
◆ Where it's heading
The direction is consistent: replace the inbox-and-spreadsheet scramble that finance teams use to track disputes and chase payments with structured, AI-assisted records. Each release tightens the loop between what a customer does and what the system does next, and the new Task Manager extends that from collections tasks to general query handling.
◆ Prediction
Expect the next moves to push AI further into dispute and query resolution itself, not just detection and routing, building on the Task Manager rebuild and the earlier reactive-workflow work.

Kill Bill cuts a new 0.25 line after a long 0.24.x reliability run
◆ Current state
Kill Bill, the open-source subscription-billing platform, ships on a slow, deliberate cadence. The just-tagged 0.25.0 opens a new minor line, but its feed entry carries only the maven-release-plugin boilerplate, so the substantive changelog isn't visible in the source. The preceding 0.24.x series was steady reliability work: invoice failure handling (retries, account parking, uniform logging), multi-tenant query indices, and operability improvements like config-source visibility.
◆ Where it's heading
The recent arc is hardening the billing core — making invoice runs fail safely, speeding multi-tenant queries, and giving operators more control over configuration and retries. The 0.25.0 cut suggests accumulated work is being promoted to a new line, though the in-feed notes don't yet detail it.
◆ Prediction
Expect 0.25.x to continue the invoice-resilience and operability focus, with detailed release notes following the tag; the next feed entries are likely 0.25.x bug-fix points.
