Overview

ISP Billing is a cloud platform for internet service providers, joining customer and service records with billing, support and network operations. It suits providers that want customer-facing and operational workflows in one ISP-focused system; teams seeking general-purpose billing software should look elsewhere.

Its breadth is useful, from quotes and recurring collections to customer self-service and ticketing. The trade-off is a 10-customer free-plan ceiling, larger paid-plan caps, and separately priced modules that can raise the cost of a deployment.

Key features

The workflow spans customer acquisition, quotes and contracts, recurring billing and collection, then ticket support and customer communications. That makes ISP Billing a more natural fit for provider operations than a billing tool centered only on invoices. It supports usage rating, prepaid and postpaid billing, plan management, invoice generation, payment collection and customer accounts.

The Customer Area and ISP APP let subscribers view documents and services, pay, open tickets, accept quotes and manage notifications. Email, SMS, WhatsApp and ISP APP are listed communication channels. These capabilities give customers several self-service routes, but the ISP App is a paid extra rather than an included feature in the listed plans.

Named integrations include Stripe, Aruba FE, MessageNet, FiberCop, UISP, Proxmox, Radius and VoIP, spanning payment, communications and network-related systems. The API documentation covers keys, permissions, pagination, resources, errors and an interactive console, a useful foundation for teams connecting the platform to their stack.

The maker says its GDPR and NIS 2 compliance programs are active, with ongoing review of procedures, organizational safeguards and technical controls. Bilingual documentation is provided, alongside email support at support@ispbilling.it and phone support at +39 080 999 6171.

Pricing

The freemium structure gives small providers a way to start without a subscription, while paid pricing is tied to customer capacity. Check the customer cap that matches your subscriber base and budget separately for any modules your deployment needs.

Plan	Price	Includes	Best fit
ISP Billing Free	0.00 EUR per free; no expiry	Up to 10 customers; service management; recurring invoices and XML; tickets, activities and quotes	Very small operations evaluating or running the core workflow within a strict 10-customer limit
ISP Billing Lite	49.00 EUR per month	Up to 1,000 customers; all Free functions; ISP Dude; Coverage Map and Communications	Smaller providers that need room beyond the free cap and the named additions
ISP Billing Gold	99.00 EUR per month	Up to 2,500 customers; all Free functions; ISP Dude; Coverage Map and Communications	Providers needing a higher customer ceiling than Lite

Lite and Gold share the listed functions, so the stated distinction is capacity: Gold raises the cap by 1,500 customers for €50 more per month. The free tier has no expiry, but its 10-customer ceiling makes it a narrow long-term fit. No free trial is offered. Optional modules are separate from the principal plan: ISP App costs €10/mese, Aruba electronic invoicing €15/mese, and ISP Billing Radius 2.0 €40/mese. Confirm module availability and pricing for the deployment before comparing total costs.

Platforms

ISP Billing is available on web, Android and iOS, with an API for integration. This mix supports browser-based operations, mobile access and connected workflows, though it does not offer a listed self-hosted deployment option.

Who it's for

ISP Billing is strongest for internet providers that want customer management, billing, support and network operations tied together, especially those able to stay within its customer caps. Its self-service options and API also suit teams aiming to connect subscriber-facing tasks with internal systems. It is less appropriate for buyers who require self-hosting, or whose required features depend on paid modules that push the total beyond budget.

Pros and cons

Pros: The no-expiry free plan includes recurring invoices, XML, service management and tickets, giving a small provider a usable core without a recurring charge.
Pros: Usage rating, prepaid and postpaid billing, plus customer self-service and named ISP integrations address provider-specific workflows rather than billing alone.
Pros: API documentation covers practical integration areas including permissions, pagination and errors.
Cons: The free plan stops at 10 customers, while Lite and Gold cap at 1,000 and 2,500 respectively.
Cons: ISP App, Aruba electronic invoicing and Radius 2.0 cost extra, so the plan price does not capture every deployment's total.
Cons: There is no free trial, and the platform is cloud-based rather than self-hosted.

Alternatives

For a broader comparison, start with Telecom Billing Software.

ISPbills is worth considering if a 100-active-subscriber free tier and self-hosted availability matter; its free plan has no monthly subscription charge, but a one-time setup costs ৳1,000.
ASTPP fits teams seeking a self-hosted community edition, if limited features and the absence of support and security updates are acceptable.
Alepo BSS Now is another paid web and mobile option for buyers who want customer management, billing, self-care and AI support under subscription pricing that scales with business success.
BillRun may suit teams wanting a paid, API-capable or self-hosted option with a free trial and subscriber-based monthly pricing.
OneBill is another paid option with a free trial and API access.
PortaSwitch is a fit for buyers considering self-hosted deployment under an unlimited, perpetual license for a specified number of servers.
Splynx is an alternative for teams seeking a paid product with a free trial and self-hosted availability; its cited Whalebone security and management add-on is $80/month for up to 1,000 subscribers, then $0.08 per subscriber.
Tridens Monetization may suit API-oriented buyers prepared for a $500.00/month one-month contract and an additional 1% of revenue billed.

Verdict

Choose ISP Billing if you run an ISP and want customer, billing, support and network workflows in one cloud platform, with a no-expiry starting tier and a clear path to 2,500 customers. Its main appeal is that ISP-specific scope; look elsewhere if you need self-hosting, a larger stated customer ceiling, or customer-facing modules included in the core plan.
