How Did We Evaluate These Telecom Billing Platforms?
We judged each tool on certain aspects which will help the customer. How well it helps telco or ISP sell and bill digital services, using only vendor pages and dated announcements.
| Criterion | What we checked |
| Service range | Bills broadband, voice and cloud subscriptions on one account |
| Billing models | Recurring, usage-based, prepaid and hybrid plans |

| Channel support | Reseller tiers, partner pricing and white-label storefronts |
| Pricing clarity | Published pricing model and USD starting price |
RackNap leads because this guide targets operators selling digital services; the rest run from enterprise BSS to ISP billing.
What Should an ISP Look for in Billing Software?
ISP billing software should be able to automate multiple functions. It should include recurring and usage-based invoicing, link billing to network access, and add digital services without a second system.
| Feature | Question to ask the vendor |
| Flexible plans | Do you support tiered, data-cap and prepaid plans with automatic proration? |
| Usage-based billing | How are usage records and voice CDRs imported and rated? |
| Network integration | Do you support RADIUS-based suspension and restoration for unpaid accounts? |
| Digital service bundling | Can broadband and Microsoft 365 subscriptions sit on one invoice? |
| Automated provisioning | Which vendors and network systems are integrated natively? |
| Payments and US taxes | Which US gateways are supported, and how are federal, state and local taxes calculated? |
| Partner support | Can resellers have their own catalogs, pricing and margins? |
| Pricing transparency | Is pricing per subscriber or flat fee, and what are the setup fees? |
ISPs selling only internet and voice should prioritize network integration and per-subscriber pricing. ISPs adding cloud and security services should prioritize bundling, vendor provisioning and partner support.

Frequently Asked Questions
1. What is telecom billing software?
Telecom billing software calculates, invoices and collects charges for telecom services. Modern platforms also handle subscriptions, usage rating, provisioning and partner billing.
2. What is the difference between ISP billing software and a telecom billing platform?
ISP billing software focuses on broadband plans and network access control, such as RADIUS. A telecom billing platform usually covers wider services, including voice, mobile and cloud subscriptions.
3. Can one system bill broadband and Microsoft 365 together?
Yes, if it supports multi-vendor catalogs and consolidated invoicing. RackNap, for example, bills connectivity and Microsoft CSP subscriptions in one customer account.
4. How much does ISP billing software cost in the US?
It varies by model. Splynx starts at $0.55 and Sonar at $1.25 per subscriber monthly, while RackNap starts at $10,000 per month plus setup and transaction fees.
5. How long does a telecom billing migration take?
It depends on data volume and integrations. RackNap reports an average deployment of three weeks from contract, while large carrier BSS migrations can take months.
6. Which Telecom Billing Software Should You Choose?
Choose by the revenue you want next, not the network you run today. Carriers rebuilding core charging fit enterprise BSS suites; ISPs billing only broadband fit per-subscriber tools like Splynx or Sonar.
If your growth depends on selling Microsoft 365, Azure or Acronis Cyber Protect Cloud alongside connectivity. RackNap’s telecom billing software puts the marketplace, provisioning, billing and partner channel on one platform, with an average deployment of three weeks.
