Zoho Books is online accounting software for small and growing businesses that handles invoicing, expenses, banking, projects, inventory, vendor bills, reporting, and end-to-end GST/VAT compliance. It is part of the Zoho Finance suite and integrates with the rest of the Zoho One platform alongside payment gateways, banks, and tax authorities. The Zoho Books REST API exposes the full accounting data model — contacts, invoices, estimates, expenses, bills, banking, items, taxes, and reports — using OAuth 2.0 (Zoho-oauthtoken) for authentication and per-region data center base URLs.
