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 Carta?
Carta is pulling fund back-office paperwork in-app, then walking into the deal team's CRM.
The recent run is dominated by one pattern: operations that used to happen over email and PDF are being moved inside Carta. Securities transfer instructions now send and track from the app, investors collect their own securities accounts through a self-service portal, wire account setup is AI-assisted, and spousal consent runs through fillable templates. The quarterly compensation benchmark refresh continues on schedule, and the newest release steps outside fund administration entirely with a CRM Chrome extension for deal teams.
SolidInvoice vs Carta: editorial side-by-side
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.
Carta
6.3FINANCE
Carta is pulling fund back-office paperwork in-app, then walking into the deal team's CRM.
◆ Current state
The recent run is dominated by one pattern: operations that used to happen over email and PDF are being moved inside Carta. Securities transfer instructions now send and track from the app, investors collect their own securities accounts through a self-service portal, wire account setup is AI-assisted, and spousal consent runs through fillable templates. The quarterly compensation benchmark refresh continues on schedule, and the newest release steps outside fund administration entirely with a CRM Chrome extension for deal teams.
◆ Where it's heading
Carta is widening from the system of record for the cap table into the system that runs the workflows around it — in-kind distributions, wires, KYC, and consents each moved from offline exchanges to tracked in-app state. The through-line is fewer handoffs to email and more self-service by the counterparty, with AI applied to the messiest input first. The CRM extension marks a second front: rather than deepening fund ops, it goes after where deal and investor-relations teams spend their day.
◆ Prediction
The distribution workflow now has account collection, transfer instructions, and status tracking in place, so the plausible next step is closing the loop into execution and confirmation without leaving Carta. On the CRM side, expect the browser capture to connect back to Carta's own entity and cap-table data, which is the only thing that would differentiate it from a general-purpose CRM.
