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.
What is Sequence?
Billing platform builds an agentic AR layer with human-in-the-loop review.
Sequence is a billing, invoicing, and revenue platform whose recent releases center on collections automation and an agentic approach to accounts receivable. Dunning workflows, Stripe retries, and an AR Agent are paired with a 'Watchtower' review step, alongside integrations (Anrok tax, GoCardless) and an MCP server.

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.

◆ Current state
Sequence is a billing, invoicing, and revenue platform whose recent releases center on collections automation and an agentic approach to accounts receivable. Dunning workflows, Stripe retries, and an AR Agent are paired with a 'Watchtower' review step, alongside integrations (Anrok tax, GoCardless) and an MCP server.
◆ Where it's heading
Sequence is heading toward automated, agent-assisted revenue operations where routine AR work is handled by software but gated behind human review in Watchtower. The MCP server opens the same billing data to external AI agents, extending the automation story beyond the app.
◆ Prediction
Expect the AR Agent and dunning automation to expand into more of the collections lifecycle, with Watchtower remaining the approval gate, and more integrations feeding the agentic workflow.
