Invoice Ninja vs SolidInvoice: at a glance
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 SolidInvoice?
SolidInvoice finally shipped the 3.0 it spent a year staging in alphas and betas.
After more than twelve months of alpha and beta releases, SolidInvoice 3.0 landed in June with the accumulated work of that cycle: email verification, Google OAuth, two-factor authentication, real user profiles, flat-rate tax support and a Meilisearch-backed search layer. Underneath it, the project moved onto a shared platform config and pulled trial and SaaS logic into an external bundle. The 2.3 line ran in parallel the whole time, absorbing security backports.

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.
SolidInvoice
0.0FINANCE
SolidInvoice finally shipped the 3.0 it spent a year staging in alphas and betas.
◆ Current state
After more than twelve months of alpha and beta releases, SolidInvoice 3.0 landed in June with the accumulated work of that cycle: email verification, Google OAuth, two-factor authentication, real user profiles, flat-rate tax support and a Meilisearch-backed search layer. Underneath it, the project moved onto a shared platform config and pulled trial and SaaS logic into an external bundle. The 2.3 line ran in parallel the whole time, absorbing security backports.
◆ Where it's heading
Two threads run through this changelog. The visible one is identity and account management catching up to what users expect from a billing app — signup verification, OAuth, 2FA, self-serve company deletion. The less visible one is the codebase being restructured around reusable solidworx platform components with Sentry and Prometheus instrumentation, which is the shape of a project preparing to run itself as a hosted service rather than only as a download.
◆ Prediction
With 3.0 out and 3.0.1 already repairing the upgrade migration path, the near-term work is likely more 3.0.x stabilization for people coming off 2.3 rather than new features.
