Case Study

VoIP Billing & Account Management

Billing, payments, and customer self-service connected to live telephony usage.

Status: Production

Problem

If usage lives in the PBX and invoices live in a spreadsheet, operators spend time assembling bills and customers cannot see what they used. Errors show up as disputes, not as a product issue.

Solution

Connected call usage to account balances and payment workflows inside the operations panel, so customers can see usage and pay, and operators can automate invoices instead of building them by hand.

Key Features

  • Account balances with prepaid and postpaid handling
  • Usage import from call detail records
  • Payment collection through Stripe, including webhook processing
  • Invoices, tax, auto-recharge, and billing reports
  • Customer portal for balances, payments, and usage visibility

Technical Architecture

Billing is implemented as part of the PBX operations platform rather than a disconnected finance tool. Call records are imported and rated against account plans. Stripe handles card payments so the application does not store card numbers. Background jobs are used for heavier billing work so the operator interface stays usable.

Challenges

  • Rating telephony usage with plan rules instead of a single flat fee.
  • Keeping payment events from Stripe aligned with account balances.
  • Giving customers enough visibility to reduce billing questions without exposing other tenants.

Who This Is For

VoIP providers who need usage-based billing and customer self-service alongside their PBX, not a generic invoicing tool.

Outcome

Built to connect call usage to balances, invoices, and payments inside the same operations platform. Collection or volume results are not currently documented.
