v0.1 preview · PHP 8.1–8.3 · MySQL / MariaDB

Billing for web hosts.
Your server, your code.

HostBMS (Host Billing & Management Suite) runs the business side of your hosting company — clients, orders, invoices, payments, provisioning and support — on your own server. A WHMCS alternative you can actually read.

✓ Free to use · Source included · No ionCube, no licence server

🔁 Coming from WHMCS? Same PHP/MySQL/Smarty stack, WHMCS-style modules and API, and a built-in migrator. See how it compares →

Menus follow the WHMCS order your staff already know — Clients, Orders, Billing, Support, Utilities, Setup — in a dark, glassy blue admin theme. Simplified illustration of the admin dashboard.

Why HostBMS

Everything to bill a host.
Nothing hidden.

Most hosting billing software is closed, encoded and licensed by the month. HostBMS is the billing system we wanted next to our own panel: familiar to anyone who has used WHMCS, and readable enough to fix at 3am.

📖 Code you can read

No ionCube, no licence server phoning home. Plain PHP 8 with Smarty templates — audit it, patch it, extend it.

🔁 Easy way out of WHMCS

Built-in migrator for clients, products, services, domains, invoices and tickets, keeping the same IDs. WHMCS-style modules, hooks and API calls keep working.

💷 Smart dunning

Reminder, card retry, late fee, suspend and terminate steps on your schedule. Stops retrying on hard declines; catches up after downtime without spamming.

🧩 Visual order forms

Drag-and-drop product order, featured plans, upsells — and A/B test two layouts with per-day views and orders.

🛡️ Secure by default

Staff 2FA, role permissions, login lockouts, an audit log of every change, and encrypted secrets. Card numbers never touch your server.

⚙️ Background job queue

Emails, provisioning and gateway calls run in a retrying queue, so a slow API never blocks a checkout.

Payments & modules

Bring your gateways.
Keep your modules.

Modules follow the WHMCS convention (module_Function($params), hooks, localAPI), so existing gateway, server, registrar and addon modules are a small port, not a rewrite.

🛣️ Roadmap

Built · v0.1

The full core

Clients, products, orders, invoicing, smart dunning, client area, support desk, module layer, automation, email, reports, quotes, REST API, Stripe + Mollie, installers and the WHMCS migrator.

Public demo & testers

A live demo install, real-world WHMCS migrations with testers, and the first production server and registrar modules.

Later

Depth

Client 2FA, product upgrades, more gateways, a one-click updater and deeper WHMCS feature coverage.

Honest limits (v0.1): early development, not production ready · the WHMCS migrator has only been tested on sample data · ships with demo server and registrar modules (real ones like cPanel or Enom come next) · English only. Expect glitches and tell us about them.
