What is telecom billing software?

Telecom billing software automates how a service provider charges subscribers: it generates recurring invoices, applies proration, taxes and fees, collects payments and tracks balances. ISPbox is telecom billing software built specifically for ISPs and WISPs, so it understands plans, packages and network-driven billing instead of treating you like a generic business.

Does ISPbox prorate the first invoice?

Yes. When a subscriber starts mid-cycle, the first invoice is prorated to your bill day, charging only the partial period, and full cycles follow from there.

Can subscribers pay online?

Yes. ISPbox supports online card payments and gives each subscriber a self-service portal to view invoices, pay and download receipts, which speeds up collections.

Is it only billing, or the whole ISP platform?

Billing is one part of ISPbox. The same platform also covers clients, services and packages, network maps and monitoring, RADIUS and provisioning, and support ticketing, so billing and operations share one source of truth.

What telecom billing software should actually do

ISPbox is telecom billing software for internet service providers and WISPs that turns subscriptions into invoices, payments and clean books without a pile of spreadsheets. It handles recurring billing, proration, taxes and fees, online payments and a customer portal in one place, so your billing keeps pace with the network instead of lagging behind it.

Recurring invoicing with correct proration

Every active service is invoiced automatically on its billing cycle. The first cycle is prorated to your bill day, so a subscriber who joins mid-month is charged for the partial period and then full cycles after that. Monthly, quarterly and annual intervals are supported, and invoice numbering, prefixes and payment terms are configurable per tenant.

Taxes, fees and adjustments handled in line

Apply VAT or sales tax, setup and add-on fees, and late fees on overdue balances, with credit notes when you need to correct an invoice. Amounts are split into net, tax and total automatically, so what the subscriber sees and what your books record always match.

Payments, portal and collections

Subscribers pay online by card and see their balance, invoices and receipts in a branded self-service portal. Payments are allocated against open invoices, so balances and collections stay accurate without manual reconciliation, and your team spends less time chasing money.

02 Why this feature matters

Built for high-speed ISP operations

Invoicing on Autopilot

Recurring invoices are generated on each subscriber billing cycle, with the first cycle prorated to the bill day, so revenue is captured correctly without manual work.

Get Paid Faster

Online card payments, receipts and a self-service portal make it easy for subscribers to pay, which shortens collection cycles and steadies cash flow.

Built for Telecom, Not Generic SaaS

Plans, packages, taxes, late fees and credit notes match how an ISP actually bills, instead of bending a generic invoicing tool to fit.

One Platform, Not Five Tools

Billing lives next to your clients, services, network and support, so finance and operations work from the same source of truth.
