What is Carta?
Carta is rebuilding core valuations and equity flows around an agentic ERP.
Carta is shipping across three lanes at once: agentic rebuilds of core financial workflows, deeper compensation data via HRIS, and global compliance reach. The Portfolio Valuations rewrite under the new Agentic ERP signals an architectural reset rather than feature polish. Quarterly benchmark refreshes and fund-admin views (Data Explorer, Intercompany Balances) keep the existing surface area accreting in parallel.
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.

Carta
6.3FINANCE
Carta is rebuilding core valuations and equity flows around an agentic ERP.
◆ Current state
Carta is shipping across three lanes at once: agentic rebuilds of core financial workflows, deeper compensation data via HRIS, and global compliance reach. The Portfolio Valuations rewrite under the new Agentic ERP signals an architectural reset rather than feature polish. Quarterly benchmark refreshes and fund-admin views (Data Explorer, Intercompany Balances) keep the existing surface area accreting in parallel.
◆ Where it's heading
The center of gravity is moving toward agent-driven workflows that fold valuations, equity docs, and reporting into one operating layer for finance teams. Compensation data is being pulled in from HRIS and refreshed on a quarterly cadence, suggesting Carta wants to be the system of record for both the cap table and the people behind it. International expansion — starting with Australia's ESS suite — points to a multi-jurisdiction compliance roadmap.
◆ Prediction
Expect more modules — financial reporting, fund admin, document workflows — to be re-shipped as agent-native within the next two quarters. A second jurisdiction (likely UK or Canada) is the obvious next compliance bundle.

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.
