Turn every subscription into predictable, scalable revenue

Subscription billing is a model where customers pay on a recurring basis (monthly, annually, or usage-based) for ongoing access to products or services. A modern solution automates pricing, invoicing, payments, and renewals so you can focus on growth, not manual billing. 

Traditional billing was built for static, product-only services. Subscription billing supports frequent changes, complex bundles, promotions, free trials, and usage-based charges — all without custom code or long projects for every new offer.

Yes. You can combine subscription fees with usage, overages, one-time charges, and partner fees on the same account and invoice, with configurable rating rules and charge timing.

CSG offers solutions that are API-first and designed to integrate with your existing stack, including CRM, CPQ, payment gateways, ERP, and data platforms, so you don’t have to rip and replace everything at once. 

Clear, accurate bills and flexible subscription controls reduce bill shock and friction. Combined with real-time data, you can proactively manage renewals, offer targeted discounts, and create journeys that keep customers engaged. 

CSG supports complex taxation, multi-currency, and multi-entity scenarios, helping you stay compliant as you expand into new regions, products, and partner ecosystems.
