Overview

ISP Billing is a cloud platform for internet service providers that ties customer accounts and services to billing, support, and network operations. It suits providers looking for an ISP-specific system spanning sales workflows and customer self-service, rather than a general-purpose invoicing product. Its no-expiry free tier is useful for a very small operation, while paid modules and customer limits are important considerations as it grows.

Key features

The workflow runs from customer acquisition through quotes and contracts to recurring billing, collection, support tickets, and customer communications. That coverage makes ISP Billing a plausible operational hub for a provider; its focus on ISP processes is less suitable for businesses with broader billing needs.

The Customer Area and ISP APP let customers view documents and services, pay, open tickets, accept quotes, and manage notifications. Providers can communicate by email, SMS, WhatsApp, and ISP APP notifications. Self-service can handle routine customer actions in the same platform, but the ISP App is a separately priced module.

Billing features include usage rating, prepaid and postpaid billing, plan management, invoice generation, payment collection, and customer accounts. Named integrations include Stripe, Aruba FE, MessageNet, FiberCop, UISP, Proxmox, Radius, and VoIP, giving providers a set of connections across payments and network-related operations. The API documentation covers keys, permissions, pagination, resources, errors, and an interactive console, which gives developers a reference for integrating with the platform.

The company says its GDPR and NIS 2 compliance programs are active and describes continuing reviews of procedures, organizational safeguards, and technical controls. That indicates ongoing compliance work, not a substitute for assessing whether the service meets an individual provider’s requirements. Bilingual documentation and support by email and phone provide routes for assistance.

Pricing

ISP Billing Free costs 0.00 EUR per free, has no expiry, and is capped at 10 customers. It includes service management, recurring invoices and XML, tickets, activities, and quotes. That is a meaningful way to evaluate the core workflow or manage a very small customer base, but the ten-customer ceiling makes it unsuitable as a lasting tier for most growing providers.

ISP Billing Lite costs 49.00 EUR per month and supports up to 1,000 customers. It includes all Free functions plus ISP Dude, Coverage Map, and Communications. This is the lower-cost paid option for providers within that cap that need those additions. ISP Billing Gold costs 99.00 EUR per month and raises the customer limit to 2,500, while retaining the listed Lite additions and Free functions. The higher tier is the fit for a larger customer base within the stated limit; the plan details do not distinguish other additions over Lite.

There is no free trial, so the no-expiry free tier is the available no-cost starting point. Optional modules remain separate from the principal plan: ISP App costs €10/mese, Aruba electronic invoicing €15/mese, and ISP Billing Radius 2.0 €40/mese. Providers who need these should factor them into the subscription decision rather than assume they are included in a tier.

Platforms

ISP Billing supports web, Android, iOS, and API access. The combination suits providers needing browser-based administration, mobile access, or programmatic integration.

Who it's for

ISP Billing is aimed at internet service providers managing customer accounts, service plans, billing, support, and network operations. The free tier makes the most sense for very small providers or an initial evaluation; Lite suits operations with up to 1,000 customers, and Gold those with up to 2,500. Providers needing a larger customer capacity or optional modules should weigh the resulting plan and add-on costs before committing.

Pros and cons

Pros: The workflow combines customer, quote, contract, billing, collection, and support tasks, which is relevant to providers seeking one ISP-focused platform.
Pros: The free plan has no expiry and includes recurring invoices, XML, tickets, activities, and quotes, making it more useful than a time-limited trial for a base of up to 10 customers.
Pros: Customer self-service and several communication channels give subscribers ways to handle payments, tickets, quotes, and notifications without relying solely on provider-initiated contact.
Cons: Free is capped at 10 customers, while Lite and Gold top out at 1,000 and 2,500 respectively; providers beyond those limits need to assess other arrangements.
Cons: The Customer Area and ISP APP include a paid ISP App extra, and other modules are also priced separately, so the plan price may not cover every required capability.
Cons: There is no free trial, and the no-cost plan's customer cap limits how far a provider can assess or use the system at scale without paying.

Alternatives

For a broader comparison, see Telecom Billing Software.

Choose ISPbills instead if its free plan for up to 100 active subscribers, free trial, and one-time setup charge of ৳1,000 better suit your starting budget and subscriber count.

Splynx is a paid alternative with a free trial and self-hosted availability; its named Whalebone Peacemaker Security & Management plan costs $80 per month for up to 1,000 subscribers, then $0.08 per subscriber.

Consider ISPbox if you want a paid, trial-available option with a stated $25 monthly minimum for 20 active subscribers and a price that scales with active subscriber count.

ASTPP is another freemium option, with a free Community Edition described as limited and without support or security updates.

Alepo BSS Now is a paid alternative for readers considering a subscription that scales with business success and includes customer management, billing, self-care, and AI support.

Cadebill is an alternative from MCL Systems Limited, which focuses on telecommunications and business process management software.

OneBill is a paid alternative with a free trial.

AEX Software may suit providers seeking per-active-subscriber pricing through a scoped proposal, with modules, subscriber count, service level, and hosting model among the factors.

Verdict

ISP Billing is a strong fit for an ISP that wants customer administration, recurring billing, support, and subscriber self-service in a single ISP-focused cloud platform. The no-expiry free plan gives very small providers a practical entry point, and the paid tiers set clear customer ceilings. Look elsewhere if your operation exceeds the 2,500-customer Gold limit or needs optional modules without separate charges.
