ISP Postpaid Billing — Invoice-Based Monthly Billing Made Simple
Manage postpaid broadband billing with monthly invoice cycles, due dates, grace periods, late fees, dunning automation, and payment tracking for ISPs.
Quick answer
Postpaid billing gives subscribers the convenience of pay-after-use — but it gives ISPs the challenge of collection management. Delayed payments, overdue invoices, and manual follow-ups drain resources. NowaCRM automates your postpaid billing cycle end-to-end — from invoice generation to payment collection to service suspension.
Configurable Billing Cycles
Each subscriber can have their own billing date. Monthly, quarterly, semi-annual, and annual cycles are supported. Billing dates are configurable per subscriber or standardized across groups. The billing engine generates invoices on schedule based on each subscriber's cycle date, handling weekends and holidays gracefully.
Automated Invoice Generation
On the billing date, invoices are generated automatically with plan charges, add-on services, prorated amounts, taxes, and any carry-forward balance. Invoice PDF is rendered and available for download immediately. Auto-email delivery sends the invoice to the subscriber's registered email address.
Due Date & Grace Period
Each invoice has a configurable due date (e.g., 15 days from generation). After the due date, a grace period (e.g., 7 days) begins. During grace, the subscriber receives escalating reminders. After grace period expiry, the subscriber is automatically suspended. Grace periods are configurable per ISP or per plan.
Late Fee & Dunning
Configure automatic late fees for overdue invoices — flat amount or percentage. Dunning reminders are sent at configurable intervals: 1 day before due, on due date, 3 days after, 7 days after. Each reminder includes the outstanding amount and a payment link. Dunning stops when payment is received.
Payment Tracking & Aging
Track payments against invoices with aging analysis. Current, 30-day, 60-day, and 90+ day aging buckets help prioritize collections. Payment history per subscriber shows all transactions. Outstanding balance is visible on the subscriber profile and in the self-service portal.
