Bigcapital adds cash and accrual basis accounting to its open-source books.
Bigcapital is an open-source accounting product releasing every week or two. v0.25.45 (October 23) brings cash and accrual basis accounting across journals, bills, credit notes and vendor credits, with a basis switch on the journal and trial balance reports. The releases before it added bank rules that apply to all accounts, report date presets and Plaid sync fixes, alongside a long run of report-correctness fixes.
Zoho Billing turns its reports toward churn and line-item revenue.
Zoho Billing's late-October run is about seeing inside subscriptions. A new Subscription Line Item report breaks every subscription into rows with quantity, price, discount and tax, churn reports now show the reasons customers gave for cancelling, and the customer portal's subscription page gains billing and usage tabs. Smaller additions let imports carry Plan IDs and let rule-based revenue recognition close out deferred revenue when a service finishes early.

The work is moving from features to accounting correctness: aging summaries, cash flow, ledger running balances and sales tax liability were all fixed in September, and the accounting-basis work extends that into how every transaction posts. Security fixes such as secure invite tokens show a codebase hardening for wider self-hosting.
Expect the accounting-basis switch to reach more reports and transaction types in the next releases. Version labels are inconsistent (v0.15.43 sits between v0.25.42 and v0.25.44), so tag numbers are not a reliable guide.

Smaller additions let imports carry Plan IDs and let rule-based revenue recognition close out deferred revenue when a service finishes early.
After a September and early October focused on item-based and services billing, the product is filling in reporting and self-service around those subscriptions. The emphasis is on explaining revenue and churn to the business, and usage to the end customer, rather than on new billing models.
Expect more subscription analytics, such as churn or line-item data surfacing in dashboards, and more early-access revenue recognition options, the two threads recent entries keep extending.
