A broad ISP billing platform linking usage, payments, customer service and accounting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Splynx is a cloud or on-premise platform for internet service providers and voice providers. It brings together recurring and prepaid billing, voice and usage rating, customer accounts, tariffs, invoices, payment collection, network access control, service provisioning and support ticketing. Its scope suits small and medium-sized ISP businesses that need billing and network operations in one system, including providers managing internet, VoIP or mobile services.
The published plans show a paid Splynx subscription with all system features, public add-ons and integrations, a customer portal and mobile app, unlimited administrator accounts, and cloud hosting by default. The core subscription is calculated from active subscriber count, while an annual billing option is marked 10% off. Separate ACS tiers add TR-069 CPE provisioning and management for 1,000 to 10,000 devices, priced from $100 to $1,000 per month. A 15-day free trial provides a way to assess the platform before committing.
Splynx stands out for combining billing depth with a broad operational ecosystem. It can generate branded PDF invoices, collect payments through cards, bank transfers, debit orders and cash, rate calls, messages and data, and apply data caps and paid top-ups. Accounting synchronization covers Sage, QuickBooks, Xero, Zoho Books and NetSuite Accounting, while payment connections include Stripe, Paystack, GoCardless, PayPal, Worldpay for Platforms and Netcash. Huawei GPON, Powerlynx, 3CX and WhatsApp integrations extend its network and customer-service reach. Choose Splynx when billing, provisioning and customer operations need to connect; choose a narrower billing tool if these network-management features are unnecessary.
