Increase vs Invoice Ninja: at a glance
What is Increase?
A banking-as-a-service API that now sells compliance and blockchain rails, not just payments
Increase ships a quarterly newsletter rather than a running changelog, so each entry bundles a quarter of API work. The last three quarters have moved past core payment rails into the surrounding infrastructure: managed compliance, entity onboarding sessions, 3D Secure, push provisioning and IP-restricted API keys. SDK coverage has widened to C#, PHP and Ruby, and the documentation was reworked to be readable by LLMs.
What is Invoice Ninja?
Invoice Ninja ships patch releases weekly; the work is payment correctness and accounting sync.
The 5.13.x line advances every few days, with each tag carrying a short list of fixes and occasional feature work. Recent releases concentrate on payment-path correctness — Stripe async webhooks, duplicate-request races, gateway fee discounts, rate limiting — plus QuickBooks sync, PEPPOL entity validation, and PDF rendering. Bulk actions were generalized across all entities in the latest tag.

◆ Current state
Increase ships a quarterly newsletter rather than a running changelog, so each entry bundles a quarter of API work. The last three quarters have moved past core payment rails into the surrounding infrastructure: managed compliance, entity onboarding sessions, 3D Secure, push provisioning and IP-restricted API keys. SDK coverage has widened to C#, PHP and Ruby, and the documentation was reworked to be readable by LLMs.
◆ Where it's heading
The arc runs from moving money to operating a bank program end to end. Early quarters added rails (FedNow, Push-to-Card, check transfers); recent ones add the compliance, onboarding and dispute machinery a customer would otherwise build or buy separately. Q2 2026 adds blockchain transfers alongside managed compliance, and flags cross-border payments and lending APIs as next.
◆ Prediction
Expect the cross-border payments and lending APIs named in the Q2 2026 letter to ship as the next quarter's headline, extending the same pattern of absorbing adjacent financial products into the core API.
Invoice Ninja
5.0FINANCE
Invoice Ninja ships patch releases weekly; the work is payment correctness and accounting sync.
◆ Current state
The 5.13.x line advances every few days, with each tag carrying a short list of fixes and occasional feature work. Recent releases concentrate on payment-path correctness — Stripe async webhooks, duplicate-request races, gateway fee discounts, rate limiting — plus QuickBooks sync, PEPPOL entity validation, and PDF rendering. Bulk actions were generalized across all entities in the latest tag.
◆ Where it's heading
This is mature maintenance with a compliance edge: the recurring themes are e-invoicing standards, tax calculation for accounting integrations, and hardening the paths where money moves. Nothing in the window changes the product's shape, and version titles carry no signal, so the release notes themselves are where direction has to be read.
◆ Prediction
Expect the 5.13.x cadence to continue at a few days per tag, with PEPPOL and QuickBooks tax handling the most likely subjects of the next substantive entries.
