What is Invoice Ninja?
Invoice Ninja adds OIDC auto-login while rebuilding its Stripe plumbing
Invoice Ninja ships v5.13 patch releases every few days. October's substance is payments and auth: Stripe moved to the 2025.basil API as a minimum with webhook upgrades, offline payment sync was finished, GoCardless, Razorpay and Braintree got fixes or upgrades, and OIDC gained auto-login and labelling. Several API fixes were found while building new mobile apps.
What is Kolleno?
Kolleno's monthly updates add DSO tracking, accessibility and e-signature forms to its AR suite.
Kolleno publishes a monthly roundup whose titles carry the news and whose bodies repeat a standing intro. October's two updates covered accessibility, a sharper Task Manager and a DSO view, then controls over AI Task Manager notes, custom forms with DocuSign e-signature and tighter security. August expanded Salesforce sync.

Invoice Ninja

Invoice Ninja adds OIDC auto-login while rebuilding its Stripe plumbing
◆ Current state
Invoice Ninja ships v5.13 patch releases every few days. October's substance is payments and auth: Stripe moved to the 2025.basil API as a minimum with webhook upgrades, offline payment sync was finished, GoCardless, Razorpay and Braintree got fixes or upgrades, and OIDC gained auto-login and labelling. Several API fixes were found while building new mobile apps.
◆ Where it's heading
The work points at two things: keeping the payment gateway layer current with providers' API versions, and preparing the backend for new client apps. European e-invoicing (ZUGFeRD/CII, EPC QR codes) also keeps getting attention.
◆ Prediction
Expect more API fixes tied to the new apps and further gateway updates; whether the apps themselves appear in this feed is unclear.
Kolleno
2.5FINANCE
Kolleno's monthly updates add DSO tracking, accessibility and e-signature forms to its AR suite.
◆ Current state
Kolleno publishes a monthly roundup whose titles carry the news and whose bodies repeat a standing intro. October's two updates covered accessibility, a sharper Task Manager and a DSO view, then controls over AI Task Manager notes, custom forms with DocuSign e-signature and tighter security. August expanded Salesforce sync.
◆ Where it's heading
The product keeps pulling collections work into one place: tasks, customer queries, reconciliation, reporting and CRM sync. AI appears inside those workflows rather than as a separate product. The June Task Manager rebuild still anchors most of what has followed.
◆ Prediction
Expect more Task Manager refinements and further CRM or ERP sync work in the next digests. The thin release bodies make specific features hard to predict.
