FreeRADIUS billing software — no server to run
Managed cloud FreeRADIUS + billing in one system. PPPoE, Hotspot, static IP and MAC auth wired directly to invoicing, mobile money and auto-suspend.
Everything you need — in one platform
We run the RADIUS servers, patches, backups and HA. You get the endpoint + shared secret.
Every auth method FreeRADIUS supports — plus EAP, TLS and MSCHAPv2.
Plan changes, top-ups and reactivations apply mid-session via RFC 3576 CoA packets.
Invoices, dunning, mobile-money and cards — with payment webhooks that flip RADIUS attributes automatically.
MikroTik, Cisco, Juniper, Huawei, ZTE, Cambium, Ubiquiti, pfSense — anything speaking standard RADIUS.
Session logs, quota usage, top talkers and NAT audit trails — queryable and exportable.
Set check + reply attributes per plan or per subscriber, without editing raw config files.
Multi-realm routing for wholesale, reseller and roaming — configured through the UI.
Import your existing users, groups and NAS entries. Run BillFi RADIUS in parallel until you cut over.
Up and running in a weekend
Bring your users, groups, huntgroups and attributes — CSV or direct DB dump.
Register your MikroTik / Cisco / Huawei NAS entries and shared secrets.
Update your NAS's RADIUS servers to our endpoint. Test with a session.
Turn on invoicing — payments now trigger CoA and unlock service.
Plays nicely with your gear
Bring the vendors you already run. BillFi drops into the middle of your stack — no rip-and-replace.
Answers, before you ask
Can I use FreeRADIUS with billing software?
Yes — FreeRADIUS is the industry-standard AAA server, and BillFi ships it managed. You get RADIUS auth + accounting wired to invoicing, without running any RADIUS servers yourself.
What happens to my existing FreeRADIUS setup?
We import your users, groups, NAS entries and check/reply attributes into BillFi's managed FreeRADIUS. You keep the same behaviour with less ops work — or run in dual mode during migration.
Does BillFi support RADIUS CoA (change of authorization)?
Yes. Plan upgrades, quota top-ups and payment-triggered reactivations send RADIUS CoA / disconnect packets, so changes apply mid-session without a subscriber-visible drop.
Which NAS vendors work with your FreeRADIUS?
Anything that speaks RFC 2865 / 2866: MikroTik, Cisco, Juniper, Huawei, ZTE, Cambium, Ubiquiti, pfSense, OpenWrt — plus every OLT vendor with a BNG in front.
Is the RADIUS server highly available?
Yes — active-active across multiple regions with automatic failover. Auth latency stays under 20ms globally, and RADIUS accounting is durable-written before we ACK.
Does BillFi store RADIUS accounting for usage-based billing?
Yes — every Acct-Start, Interim-Update and Acct-Stop is stored and rolled up per subscriber, per plan, per day. Usage-based plans (data caps, FUP throttling, overage billing) run off this data.
Can I run EAP / MSCHAPv2 / PEAP for enterprise WiFi?
Yes — the managed FreeRADIUS supports PAP, CHAP, MSCHAPv2, PEAP, EAP-TLS and EAP-TTLS. Great for enterprise WPA2-Enterprise WiFi as well as consumer PPPoE.
How do I point my NAS at BillFi's RADIUS?
Add BillFi's RADIUS endpoint and shared secret to your NAS as the auth + accounting server. Standard ports 1812 / 1813 (UDP). We provide per-vendor how-tos for MikroTik, Cisco, Huawei and ZTE.
Does BillFi log failed RADIUS auths for troubleshooting?
Yes — every reject with the reason (bad password, expired plan, walled-garden, NAS not authorized) is logged and searchable in the admin UI. Cuts subscriber-side debugging to seconds.
Can I bring my own FreeRADIUS if I want to self-host?
Yes — Enterprise customers can self-host FreeRADIUS on their own VMs, with BillFi as the control plane. We provide the SQL schema, dictionaries and sync connectors.
