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.

What is Mollie?

Mollie's Payments API now supports embedded saved cards — a real concession to merchants who own their checkout.

Mollie just enabled saving cards during checkout directly via the Payments API, letting merchants build fully embedded 1-click flows without redirecting to Mollie's hosted page. Alongside it: partial credit notes for specific invoice items, a new Methods Component beta for custom low-code checkouts, expanded webhook reference with permission requirements, and integration updates (Prestashop 6.4.3, VirtueMart for Joomla). Several smaller dashboard ergonomics ship in the same window.

Invoice Ninja vs Mollie: editorial side-by-side

I5.0

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.

5.3

Mollie's Payments API now supports embedded saved cards — a real concession to merchants who own their checkout.

◆ Current state

Mollie just enabled saving cards during checkout directly via the Payments API, letting merchants build fully embedded 1-click flows without redirecting to Mollie's hosted page. Alongside it: partial credit notes for specific invoice items, a new Methods Component beta for custom low-code checkouts, expanded webhook reference with permission requirements, and integration updates (Prestashop 6.4.3, VirtueMart for Joomla). Several smaller dashboard ergonomics ship in the same window.

◆ Where it's heading

Mollie is repositioning from a hosted-checkout payments processor toward a more developer-platform shape — saved cards in the Payments API, the Methods Component low-code SDK, and the Unmatched credit transfers API all point the same direction. The webhook reference work and Token ID search in logs suggest the team is building for serious integrators who run Mollie alongside other payment rails.

◆ Prediction

Expect more checkout primitives to migrate from hosted-only to API-accessible (likely subscriptions and recurring billing next), and the Methods Component beta to graduate with deeper customization. Continued European e-commerce platform integrations remain on the conveyor belt.
