Turn complex billing into predictable revenue
Billing shouldn’t hold your business back. You’re managing subscriptions, usage, partners, and bespoke B2B contracts—often on systems built for a simpler world. CSG gives you billing and monetization platforms that support any business model, keep charges accurate, and turn every invoice into a moment your customers can trust.
Transform the billing experience
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.
Monetize any model without adding chaos
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 every way your customers want to pay
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.

Run billing with less manual effort and fewer systems
Replace spreadsheets and stitched-together tools with a single billing engine that automates rating, invoicing, collections, and adjustments.
Automate bill cycles, proration, dunning, and adjustments so your teams spend less time fixing errors.
Reduce vendor sprawl by consolidating point solutions into one platform that scales with your growth.
Give finance, operations, and care one accurate view of charges, payments, and balances.

Make every invoice clear, accurate, and compliant
Your bill is where your customers decide if they trust you. CSG helps you get charges right the first time and makes it easy to explain every line.
Use real-time rating and charging so usage and discounts are always reflected correctly.
Support multi-jurisdiction tax, fees, and regulatory rules so invoices stay compliant as you expand.
Reduce disputes with clear invoice layouts and data that matches what customers actually used.

Make billing match the business you’re becoming
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.

"I am 100% confident that the reduction in system-caused billing errors (which tend to repeat until fixed) was a big driver of the improvement [in CSAT]. System errors have gone from the single biggest cause of billing errors in customer invoices to fourth or fifth place in the list and that is due in large part to the CSG team."
-Roger Butt, Former Executive Director of Billing Operations, Viasat
