LOCAL-FIRST · EXPORT WHEN READY

Plain text in.Polished invoice out.

Create, preview, and refine your invoice in the browser, then export a client-ready document when it is ready. The same Markdown source works in the open-source CLI, and your invoice content stays on your device. Multi-currency tables, authored totals, and deliberate page breaks keep complex invoices readable.

Made for humans.Driven by Agents

Shape an invoice by hand in the visual editor, or let your authenticated agent create and validate the same strict ttyinv/v1 document through REST or MCP. Multi-currency tables, authored summary rows, and page-break intent travel with that source.

THE WORKFLOW

Human-readable at every step.

002—004
[01]

Own the source

Your invoice is a readable Markdown file—not a record trapped in somebody else’s dashboard.

[02]

Fidelity without hand-fixing

Keep multi-currency display columns, authored subtotal and grand-total rows, and the amounts you wrote visible in the final document.

[03]

One contract, every surface

The visual editor, open-source CLI, REST API, and MCP transport share the same strict invoice contract and rendering behavior.

[04]

Breaks where you choose

Place an explicit page-break marker before a section when a long invoice needs a predictable new page.

ONE FILE. NO LOCK-IN.

An invoice you can diff, version, and understand.

The ttyinv/v1 schema keeps the structure predictable while leaving the content comfortably human. Commit it to Git, email it, or archive it for years.

  • Strict validation before export
  • Git-friendly plain text
  • Portable across the CLI and web editor
  • Authored totals and deterministic page breaks
