The full review of ISP Billing
Overview
ISP Billing is a cloud platform for internet service providers that brings customer accounts, services, billing, support, and network operations together. It is best suited to ISPs that want one system spanning commercial workflows and customer self-service, rather than a general-purpose billing tool. Its free entry point is unusually practical for a small customer base, but growth brings firm customer caps and optional modules can add to the bill.
Key features
The workflow covers customer acquisition, quotes and contracts, recurring billing and collection, then tickets and customer communications. That breadth can reduce the need to manage these ISP-specific tasks across separate systems; the trade-off is that the platform is tailored to providers rather than businesses seeking a generic invoicing package.
Customers can use the Customer Area and ISP APP to view documents and services, pay, open tickets, accept quotes, and manage notifications. Email, SMS, WhatsApp, and ISP APP notifications give providers several routes for customer contact. These self-service functions are valuable for reducing routine back-and-forth, though ISP App is a separate paid module.
Billing capabilities 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, covering payment, communications, and network-related connections. The API documentation addresses keys, permissions, pagination, resources, errors, and an interactive console, a useful foundation for teams connecting their own systems.
The maker says its GDPR and NIS 2 compliance programs are active, with ongoing review of procedures, organizational safeguards, and technical controls. Bilingual documentation and support by email or phone are also provided.
Pricing
ISP Billing is freemium, with no free trial. The free plan has no expiry and costs nothing. It supports up to 10 customers and includes service management, recurring invoices and XML, tickets, activities, and quotes. That is a meaningful way for a very small ISP to start, but the 10-customer ceiling makes it a poor fit once the operation grows beyond a pilot or tiny customer base.
ISP Billing Lite costs €49 a month and supports up to 1,000 customers. It includes all Free functions, plus ISP Dude, Coverage Map, and Communications. It is the clearest fit for a small provider that needs more capacity and those additions without moving to the higher tier.
ISP Billing Gold costs €99 a month and raises the customer limit to 2,500 while including all Free functions, ISP Dude, Coverage Map, and Communications. It suits providers that need the higher cap; compared with Lite, the stated plan difference is capacity, so a provider below 1,000 customers has no stated reason to pay more.
Optional modules are charged separately from the principal plan: ISP App is €10/mese, Aruba electronic invoicing is €15/mese, and ISP Billing Radius 2.0 is €40/mese. These extras can materially change the cost, especially for customers who want the app or Radius functionality, so budget for them separately rather than treating the plan price as the full package.
Platforms
ISP Billing supports Android, iOS, web, and API access, giving providers mobile, browser, and integration options.
Who it's for
Choose ISP Billing if you run an ISP and want customer management, service and plan administration, billing, collections, support, and customer communications tied into one workflow. Its free tier is most useful for a provider with no more than 10 customers, while Lite and Gold make the product relevant at larger but still capped customer counts. Look elsewhere if your customer base exceeds 2,500 or if a general-purpose billing product would better match your operation.
Pros and cons
- Pros: The no-expiry free plan includes recurring invoices, XML, tickets, activities, and quotes, so a tiny ISP can use core operational functions without a monthly subscription.
- Pros: Customer self-service covers payments, tickets, quote acceptance, and documents, while multiple notification channels support customer communications.
- Pros: Prepaid and postpaid billing, usage rating, and named integrations address needs specific to ISP operations.
- Cons: The free plan is capped at 10 customers, and paid tiers top out at 2,500, limiting its fit for larger providers.
- Cons: Optional modules are separate charges, so features such as the ISP App or Radius 2.0 raise the cost beyond the main plan.
Alternatives
Telecom Billing Software is a category directory for comparing options across telecom billing.
Consider ISPbills if its free plan for up to 100 active subscribers is a better match; it has no monthly subscription charge but a one-time setup fee of ৳1,000. Alepo BSS Now is another paid option, with subscription pricing described as scaling with business success and customer management, billing, self-care, and AI support. AEX Software may suit buyers looking for subscriber-based pricing and a choice of hosted, self-hosted, or hybrid deployment. Aradial is an alternative paid billing product. ASTPP is another freemium option. BillRun offers a free trial and a tiered monthly per-subscriber plan. OneBill is a paid option with a free trial. PortaSwitch is a paid alternative with self-hosted and SaaS deployment options.
Verdict
ISP Billing is a strong fit for small and midsize ISPs that want billing, customer operations, support, and self-service in one provider-focused platform. The no-expiry free tier is a practical starting point, and the paid tiers offer clear capacity steps. Choose another product if you need more than 2,500 customers or want the customer app and other optional modules without separate charges.
