Mollie vs Invoice Ninja
A side-by-side editorial comparison of Mollie and Invoice Ninja — release velocity, themes, recent moves, and the top alternatives to consider.
Mollie vs Invoice Ninja: at a glance
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.
What is Invoice Ninja?
Invoice Ninja's point-release train adds passkeys and global tags amid steady fixes
Invoice Ninja ships a frequent GitHub release train for its open-source invoicing platform. The cadence is fix-and-feature point releases: passkey login, global tags across entities, PHP 8.5 support, ZUGFeRD and SwissQR e-invoicing work, and QuickBooks sync improvements, interleaved with dependency bumps and bug fixes.

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.

Invoice Ninja's point-release train adds passkeys and global tags amid steady fixes
◆ Current state
Invoice Ninja ships a frequent GitHub release train for its open-source invoicing platform. The cadence is fix-and-feature point releases: passkey login, global tags across entities, PHP 8.5 support, ZUGFeRD and SwissQR e-invoicing work, and QuickBooks sync improvements, interleaved with dependency bumps and bug fixes.
◆ Where it's heading
The product is steadily broadening payments, e-invoicing compliance (ZUGFeRD, SwissQR), and accounting integrations (QuickBooks) while modernizing auth (passkeys) and the API (filters, sorting, tags). It is incremental maintenance and breadth, not a directional shift — a mature OSS tool thickening its feature surface release by release.
◆ Prediction
Expect continued e-invoicing format coverage, payment-gateway additions, and API refinements on the same rapid point-release cadence.
