Common questions
Why look for a Splynx alternative?
The most common reasons operators leave Splynx: per-module pricing that scales badly with the subscriber count, weak native support for African / South-Asian mobile-money rails, and slower support outside of European hours. BillFi bundles every module in one price and has direct rails for M-Pesa, MoMo, bKash and Nagad.
Is BillFi easier to migrate to than Splynx?
Yes — we import Splynx subscribers, plans, invoices and RADIUS entries directly via its API. Most Splynx → BillFi migrations complete in a weekend, with the RADIUS cut-over happening in a 20-minute window.
How does BillFi pricing compare to Splynx?
BillFi is per active subscriber, all-inclusive. Splynx charges per module (billing, RADIUS, monitoring, portal, HR, etc.). For a 2,000-subscriber ISP using more than 3 Splynx modules, BillFi is typically 30–50% cheaper.
Does BillFi support the same hardware Splynx does?
Every vendor Splynx supports (MikroTik, Cisco, Huawei, ZTE, TP-Link, Cambium, Ubiquiti) is supported by BillFi, plus BDCOM OLTs and full TR-069 ACS for FTTH.
What are the top Splynx alternatives in 2026?
The most-considered Splynx alternatives are BillFi (best for emerging markets, mobile-money first, bundled pricing), Sonar (US market, strong CRM), Powercode (US WISPs), and Visp.net (mid-size ISPs). BillFi is usually the shortest deployment and lowest TCO for operators in Africa, South Asia and LATAM.
Does BillFi cover the client / customer portal Splynx offers?
Yes — branded self-service web portal and iOS / Android apps for subscribers, plus a reseller portal for agent networks. No add-on module fee.
How does support compare?
BillFi runs 24/7 chat + WhatsApp support, with average first-response under 8 minutes. Splynx support is tiered by partner and time zone; many operators cite this as the reason they switched.
Will I lose historical data if I migrate off Splynx?
No — every invoice, payment, RADIUS accounting record, ticket and network device is imported and remains searchable in BillFi. We provide a signed data-integrity report at the end of migration.
Can I run BillFi and Splynx in parallel during evaluation?
Yes. During trial we can import a read-only snapshot of your Splynx setup so you can compare workflows on real data before cutting RADIUS over.
