Changing billing software is one of the biggest decisions an ISP makes. Pick well, and renewals, collections and complaints run on their own. Pick badly, and your team spends months fighting the system and moving data again.
There is no single “best” ISP billing software for everyone. The best one is the one that fits your network, your subscribers and the way your team works. This checklist helps you compare options and ask the right questions before you sign.
Start with your own requirements
Before you look at any vendor, write down:
- Subscribers today and in two years: 300 and 3,000 need very different systems
- Network setup: MikroTik, RADIUS, bandwidth manager, FTTH or wireless
- How you collect money: online, cash through collectors, resellers
- Team: who uses the system, from billing staff to field engineers
- Branches and partners: one office, several areas, or a reseller network
These answers tell you which features are essential and which are nice to have.
Must-have features checklist
1. Billing and renewals
- Recurring invoices for prepaid and postpaid plans
- GST-compliant invoices and tax reports
- Automatic reminders before expiry
- Auto-renewal when payment is received
2. Network integration
- RADIUS integration for login, speed and plan control
- Automatic suspension of expired users and restoration on payment
- Works with the bandwidth managers and routers you already use (for example MikroTik, Jaze, Height8, IPACCT)
This is the single biggest difference between ISP billing software and a general billing app.
3. Payments and collections
- Online payment gateways with payments recorded automatically
- Cash collection by field staff, with a clear record of what each collector holds
- A live dues list sorted by amount and age
4. Customer and document management
- One record per subscriber with plan, history, dues and complaints
- Digital CAF and KYC documents stored securely
- Quick search across all customers
5. Complaints and support
- Every complaint logged as a ticket and assigned to an engineer
- Status visible to support staff and to the customer
- Reports on open, fixed and closed complaints
6. Self-service for subscribers
- A customer portal and mobile app for recharge, payment history and tickets
- Notifications by SMS, email or app
7. Operations and reporting
- Inventory of routers, ONUs and cable, ideally with verification when stock is issued
- Staff attendance and, if you need it, salary records
- A dashboard with renewals, collections, complaints and churn; see the 12 numbers to check daily
- Reseller and branch management if you have partners
Questions to ask every vendor
- Is the software built only for ISPs, or is it a general billing tool?
- How does it connect to my RADIUS and routers? Can you show it working?
- Will you migrate my existing subscriber data, and how long does it take?
- Is training included for billing, support and field teams?
- How is support provided: phone, email, WhatsApp? What are the support hours?
- Is it cloud-based or installed on my server? Who handles backups?
- Can I export all my data if I ever leave?
- How is pricing calculated: per subscriber, flat monthly or one-time?
- Can I speak to two or three ISPs who use it today?
Red flags
- No live demo with your own plans, only slides
- RADIUS or router integration “coming soon”
- Data migration not included or charged separately without a clear quote
- No way to export your data
- Support only by email, or only in office hours, when your network runs 24/7
- Prices that change for every feature you ask about

Most ISP-focused billing systems integrate with common bandwidth managers and RADIUS. Ask the vendor to show the integration with your setup during the demo.
