Telecommunications

Telecom: subscription/billing, customers, helpdesk.

Challenges

  • Subscriber usage — minutes, gigabytes — is never linked to the invoice.
  • Line and number inventory is kept in a separate list.
  • For a corporate customer, hundreds of lines cannot be consolidated into one invoice.
  • Cancellations and transfers cannot be traced back afterwards.

Workflows

Subscriber lifecycle

  1. A subscriber record is opened and a line and number are assigned from inventory.
  2. The tariff and the commitment period are defined.
  3. Cancellation or transfer runs on the very same record.

Usage-based billing

  1. Period usage — minutes and data — is written to the subscriber record.
  2. Usage beyond the tariff is calculated as an overage charge.
  3. For a corporate customer, all lines are consolidated into one invoice.

Frequently Asked Questions

Can I track the line inventory?

Yes — lines and numbers are tracked as unique resources, showing free and assigned status.

Can I see commitment end dates in advance?

Yes, the commitment period is kept on the subscriber record and expiring contracts are listed in advance.

Can I trace number transfers retrospectively?

Yes, transfers and cancellations are posted to the same subscriber record; the activity history is shown with its date.
