## How agents use Zoho Invoice

Inside a Definable workflow, Zoho Invoice is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → Zoho Invoice** — the Researcher (GPT-5.5) pulls context from Zoho Invoice (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → Zoho Invoice** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into Zoho Invoice (create record, post message, draft email).
- **Designer / Engineer → Distributor → Zoho Invoice** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via Zoho Invoice (attach file, open PR comment, post status).

The Verifier checks every Zoho Invoice call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
