Zoho
End-to-end billing and revenue management system
Zoho Billing is an all-in-one billing and revenue management platform built to handle every stage of the quote-to-cash process, serving organizations of any scale — from growth-stage businesses to large enterprises.
One platform, every billing model
It natively handles one-time invoices, recurring billing, subscription management, usage-based pricing, and project billing. A single invoice can combine a subscription plan, project hours, a one-time fee, and tracked usage — without manual collation.
Subscriptions and payments
The full subscription lifecycle is automated: free trials, upgrades and downgrades with proration, mid-cycle changes, renewals, and cancellation workflows. Configurable dunning sequences retry failed payments and attempt fallback methods. Real-time dashboards surface MRR, ARR, churn rate, and customer lifetime value. Zoho Billing connects with Stripe, PayPal, Razorpay, and more, supports multiple currencies, and offers PCI DSS-compliant checkout and a self-service customer portal.
Usage-based billing
It supports various monetization models including metered, tiered, volume, package-based, and prepaid credit models let businesses charge for modern consumption types, inputs, messages, actions, and outcomes.
Automation, AI, and compliance
CPQ turns approved quotes into invoices without re-entry. Workflow automation handles invoice generation, approvals, and event-triggered communications. AI surfaces anomalies, forecasts, and insights alongside Zia, a conversational billing agent. GST, VAT, US sales tax, multi-currency, and localized invoicing are handled natively for global teams.
The Zoho ecosystem
Native integrations with 40+ Zoho apps including CRM, Books, Analytics, and Desk, give sales, finance, and support teams a unified view of every customer.
