SolidInvoice vs Square: at a glance
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.
What is Square?
Square's release feed is capturing headings, not releases — same title, three different dates.
Five of the six entries are generically titled roll-ups across orders, menus, discounts, inventory, payments and sign-in, with bodies that restate the title and a date. The sixth is a page scrape carrying browser-upgrade boilerplate alongside Food & Beverage marketing copy.

SolidInvoice

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.
Square
0.0FINANCE
Square's release feed is capturing headings, not releases — same title, three different dates.
◆ Current state
Five of the six entries are generically titled roll-ups across orders, menus, discounts, inventory, payments and sign-in, with bodies that restate the title and a date. The sixth is a page scrape carrying browser-upgrade boilerplate alongside Food & Beverage marketing copy.
◆ Where it's heading
There is no product trajectory legible here. Square is clearly shipping on a near-weekly cadence across its seller surfaces, but the captured entries carry category labels instead of the changes themselves, and near-identical roll-ups repeat across consecutive days.
◆ Prediction
The cadence will hold, but nothing in these entries supports a claim about what Square ships next — the detail would have to come from the linked release notes rather than these summaries.
