Real-time rating & billing
Charge every call, SMS and session the instant it happens. VOIXYS rates traffic in milliseconds on CGRateS—the open-source engine—so balances, margins and invoices are always accurate. No black-box billing, no proprietary API.
A rating engine you can audit, not a black box
CGRateS is a battle-tested open-source rating and charging engine used by carriers worldwide. VOIXYS runs it at the core of your billing—rating events as they happen, holding balances per account, and exporting clean CDRs. Every rate, every markup and every charge is transparent and reproducible.
100% open source—there is no proprietary API in the charging path and no per-event surcharge. Self-host CGRateS on your own infrastructure, or let us run it as a managed SaaS. Either way, your rate plans, CDRs and customer data stay yours.
Rating engine
Everything you need to bill traffic
From the first rated event to the monthly invoice—one transparent, open-source billing stack.
Real-time rating
Every call, SMS and session is rated the instant it ends—balances and usage update in milliseconds, not overnight.
Prepaid & postpaid
Run prepaid wallets with hard balance enforcement or postpaid accounts with billing cycles—per account, side by side.
Multi-currency rate plans
Price traffic in any currency with destination, time-of-day and tiered rates—separate plans for wholesale and retail.
Rate import & management
Bulk-import carrier rate sheets via CSV or API, schedule rate changes, and version every update for a full audit trail.
Balances & top-ups
Monetary and free-minute balances, auto top-up triggers, low-balance alerts and instant credit—all under one account.
CDR processing
Capture, rate, deduplicate and store every CDR. Stream them out to your data warehouse or download them on demand.
Automated invoicing
Generate branded PDF invoices on each billing cycle, with taxes, credits and usage breakdowns—emailed automatically.
Reseller margins & markups
Layer percentage or fixed markups per reseller and sub-account, so every tier keeps its margin automatically.
Credit limits & fraud controls
Enforce credit ceilings, concurrent-call caps and spend thresholds, with automatic blocking on suspicious traffic spikes.
Your billing, on your terms
Let us operate the rating engine for you as a managed SaaS, or run the exact same open-source stack on your own infrastructure. No proprietary API sits between your traffic and your invoices—so you can verify every charge and keep full control of your data.
