FluxBilling
Product · Platform features

One billing platform, six surfaces, no sync layer.

Billing, DCIM, provisioning, IPAM, reseller, and a visual plugin builder — built into the same database, the same audit log, the same admin panel. Pick any surface to read the deep-dive.

Each area below links to a page that explains what it does, what it ships with, and how it fits into the platform.

In the panel

Real surfaces, not a sales deck.

Three frames from the running product. Same database, same auth, same audit log behind each one.

dcim · rack

Across every surface

The plumbing that runs underneath all six.

Things you only build once when the surfaces share a database. Things you build six times when they don’t.

Inbound webhooks
Per-gateway signature verification on inbound payment webhooks (Stripe / PayPal / plugin gateways). Replayable from the panel.
Reseller integration
HMAC-signed partner endpoints with per-key rate limits, audit log, and webhook deliveries to the reseller's own URLs.
Multi-region
Master + tenant-pod model on K3s. Run customers in EU, US, or both. Per-region database and backup cron.
Audit log
Every state change, who triggered it, which actor (user/API/cron/webhook). Exportable, retained per tenant.
DDoS sensor + WAF
In-house sensor package on edge nodes feeds a WAF that scores and bans abusive IPs across the fleet.
Disaster recovery
Per-location backup cron, standby instances, restore + failover services with a DR dashboard.
Cloudflare Tunnel
Zero-trust ingress for tenant pods without exposing origin IPs. Bound into the K3s deployment flow.
Console relay
Websocket-backed live updates for active console sessions — KVM, IPMI Serial-over-LAN, and RFB/VNC.
Domain registrar
Domain workflow with registrar plugins, contact records, and renewal billing tied to the same invoice ledger.
Auth provider plugins
Pluggable login providers: local, OAuth, SAML, and 2FA — added without touching the auth core.
Internationalization
Defaults + overrides translation system. Admins enable languages and override any string per tenant.
K3s deployment
Tenants run as Kubernetes pods, not Docker containers. Rolling updates patch the fleet from a single release tarball.
AI assistance
AI-drafted and AI-refined ticket replies, plus AI blog generation with SEO metadata. Bring your own key (Anthropic / OpenAI) or any ai-provider plugin — staff review every draft before it sends.
Email templates
Every transactional email is a Handlebars template stored per tenant. Edit subject, body, and branding from the admin panel.
Notification channels
Telegram, Discord, Slack, or any webhook target as notification-type plugins with per-event message templates.
Feature toggles
Switch off surfaces you don't use. Disabled features are removed from both panels and blocked at the API, not just hidden.
