[sridharkalaibala]

Parent: #34

Goal

Separate Zoho Inventory connector needs from Zoho Books invoice export work.

Scope

Research official Zoho Inventory APIs for items, sales orders, invoices, stock adjustments, and auth.

Acceptance criteria

• Research table lists endpoint/capability, auth requirement, rate or plan limitation, and recommended phase.
• It clearly separates Zoho Books and Zoho Inventory responsibilities.
• It says whether manual CSV is a safer first PR.
• No code or live credentials are required.

Out of scope

• No production credentials, customer records, tax IDs, payment data, or private payloads in the repo or issue comments.
• Do not claim a live integration is supported until a maintainer accepts the matching fixture and evidence.
