Your billing platform shouldn't bill you per client.

ExaBill is billing, provisioning and client management for independent VPS and Proxmox hosts. One flat price, unlimited clients. Native integrations instead of third-party modules. And a migration tool that reads your WHMCS database, because we know that's the only reason you haven't left yet.

FLAT RATE

Figures from public 2026 price lists and provider forum reports.

We read the forums so we could build the fix.

Every line below is a recurring complaint from hosting communities about the incumbent. Each one is a design requirement for ExaBill.

grievance 01: Per-client pricing tiers that rise every January, with automatic license upgrades you can't refuse. You get punished financially for growing.
grievance 02: A legacy codebase dragging years of backwards compatibility. Client areas that take double-digit seconds to load. Your customers see that.
grievance 03: Core features like Proxmox left to third-party module vendors with notoriously absent support. Your stack deserves first-party treatment.
grievance 04: Long-standing bugs in core flows reported by customers of ten-plus years, and ignored. Loyalty should buy attention, not silence.
grievance 05: Everyone wants to leave; nobody can, because no alternative covers their integrations or offers a credible migration path. So we're building the exit, not just another destination.

Deliberately narrow. Properly finished.

ExaBill doesn't try to replace two hundred mediocre modules. Version one covers the stack independent hosts actually run, natively and completely.

Proxmox, first-party

Order to running VM without a plugin vendor in between: provisioning, suspension, reinstalls, console access, usage-based add-ons.

WHMCS migrator built in

Point it at your database. Clients, services, invoices, credit, tickets and domains come across in one supervised run, with a dry-run report first.

The integrations that matter

DirectAdmin, PowerDNS, major registrars, Stripe and SEPA direct debit at launch. Few, native, maintained by us.

European by design

EU-hosted, GDPR-clean, VAT OSS handled, e-invoicing ready (Factur-X) as France and the EU make it mandatory. US incumbents treat this as an afterthought.

Fast, modern, auditable

A current stack with no legacy fallbacks, sub-second client area, a complete API, and a security posture we publish instead of promising.

Self-hosted or managed

Run it on your own metal — you're a host, after all — or let us run it for you. Same product, your choice, no hostage pricing either way.

Pricing you can put in a spreadsheet once.

€14.90 /mo $54.95 + upgrades + modules

Flat. Unlimited clients, unlimited staff, every integration included. Early waitlist supporters lock this price for life. If you grow to five thousand clients, we'll be happy for you — not invoicing you for it.

Be the reason v1 ships right.

Join the waitlist and you'll get the build log, early access, the founder price lock, and a say in which integration ships third. No spam; roughly one email a month.

Honest status: ExaBill is in active development by the team behind the AS202827 network and the Exagroup hosting stack. We run our own infrastructure, so we're our own first customer. The waitlist exists to prove demand before we polish — if this page convinced you, that's the signal we need.
