You need more than a rating engine or an invoice generator. You need one place to manage offers, usage, pricing, invoicing, and revenue across every product and channel.
CSG unifies subscription and usage billing, charging, and revenue management so you can launch new services faster, simplify operations, and keep your numbers—and your customers—right where you want them. On top of that, make sure your customers are proactively communicated with to ensure they are paying their bills on time.
Whether you sell recurring services, usage, one-time fees, or partner bundles, CSG helps you define offers once and bill them everywhere. You move away from rigid legacy stacks to cloud-native platforms that support new models, reduce manual work, and give finance, operations, and product a shared view of revenue.
Support subscription, usage, hybrid, and B2B2X models on a single billing platform, so you can say “yes” to new ideas without rebuilding your stack each time.
Configure pricing once for subscriptions, usage, and one-time fees and reuse it across offers and channels.
Introduce new bundles, add-ons, and discounts quickly so you can test and refine what works.
Handle complex hierarchies and shared contracts so enterprise customers see one clear, consolidated bill.

You’re shifting from one-off products to ongoing relationships. CSG lets your billing keep up—with the flexibility to support new services, partners, and models without starting from scratch each time.
Bring subscription, usage, and partner billing into one engine that feeds clear, consistent invoices. When you change a price, tax rule, or offer once, every downstream bill reflects it, so you reduce errors and manual corrections.
