Bigcapital vs Kill Bill: at a glance
What is Bigcapital?
Bigcapital ships multiple releases per week, adding SMS notifications, banking audit logs, and Plaid hardening.
Bigcapital is an open-source cloud accounting product shipping at a high cadence — multiple tagged releases per week across server, webapp, and SDK layers. The last two weeks show a focused push on banking features: Plaid sync hardening, audit logs for banking modules, auto-recognition of bank transactions via queue, and a landed cost feature flag. SMS notifications are being wired in behind a feature flag, alongside a broad internal refactor from snake_case to camelCase API responses.
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.

Bigcapital

Bigcapital ships multiple releases per week, adding SMS notifications, banking audit logs, and Plaid hardening.
◆ Current state
Bigcapital is an open-source cloud accounting product shipping at a high cadence — multiple tagged releases per week across server, webapp, and SDK layers. The last two weeks show a focused push on banking features: Plaid sync hardening, audit logs for banking modules, auto-recognition of bank transactions via queue, and a landed cost feature flag. SMS notifications are being wired in behind a feature flag, alongside a broad internal refactor from snake_case to camelCase API responses.
◆ Where it's heading
The product is deepening its banking and financial operations surface. Plaid integration is getting production-grade attention (concurrent-run guards, proper disconnect handling, audit trails), and landed cost accounting signals a move toward more complex inventory and purchasing workflows. The API SDK with typed OpenAPI coverage is being built in parallel, suggesting a platform push toward integrations and potentially a public API offering.
◆ Prediction
SMS notifications and the typed SDK will likely ship out of feature-flag status as the next named releases. Landed cost, once out of flag, will be the headline capability for users with inventory and import workflows.
Kill Bill

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.
