Features
Everything you need to run a hosting business
One place for your store, billing, automation and support. Built for small and growing hosting companies, and easy for your customers to use.
Coupons and add-ons
Percent or fixed coupons with limits and share links. Sell add-ons like backups or a dedicated IP, billed and renewed with each service.
Domains
Customers search, register and transfer domains. Nuvabill renews them at ResellerClub, Namecheap, Enom or OpenSRS and sends expiry reminders.
VPS inside the client area
Virtualizor and Proxmox servers: customers start, stop and restart, see live usage and IPs, open a console in the browser, reinstall the OS and reset the root password without leaving your site. Sell extra CPU, RAM, disk and IPs with sliders. Hetzner, VirtFusion and SolusVM are free on the Marketplace.
Your own dedicated servers
Keep your machines on the Hardware page and sell them from stock. Your team presses Server is ready, and a machine that ends waits for a disk wipe. Add power buttons, switch ports and automatic OS installs from the Marketplace.
Import from WHMCS, Blesta, FOSSBilling or Paymenter
See a dry run first, then move clients with their passwords, products, services, domains, invoices and tickets. Run it again before you switch; it never makes copies.
Sign in with Google, GitHub or Facebook
Customers create an account or sign in with one click. They can connect or remove these accounts from their profile.
Invoices and PDFs
Numbered invoices with PDF download, payment history, reminder emails when a payment is late, credit notes and CSV exports for your accountant.
Taxes, quotes and a client wallet
VAT, GST or sales tax by country and state. Send quotes that become invoices when accepted. Clients add funds to a wallet and pay in one click.
Affiliate program
Every client can share a link. When the people they send pay, they earn a commission, held until the refund window ends and paid into their wallet.
12 languages
The client area and admin area in the most used languages in the world, from Spanish, French and German to Arabic, Kurdish, Chinese, Thai and Mongolian. Right-to-left pages, and everyone picks their own language.
REST API and passkeys
Connect your own tools with the REST API. Staff and clients can sign in with a passkey: a fingerprint, face or phone instead of a password.
Stripe, PayPal, FIB, FastPay and Wayl
Take card and PayPal payments, and Iraqi payments with FIB (with a QR code), FastPay and Wayl. Show prices in dollars and charge in dinar at the rate you set. Every payment is recorded once.
cPanel, DirectAdmin and Plesk
When an invoice is paid, the hosting account is created on your server. Unpaid services are suspended and unsuspended for you. Clients open their panel with one click.
Renewals on autopilot
A daily job creates renewal invoices, charges the card or PayPal account clients saved, sends reminders and suspends or ends overdue services, based on rules you set.
Support tickets
Departments, priorities and email alerts, a knowledge base that suggests answers while clients write, announcements and a network status page.
Mobile-first client area
Services, invoices and tickets work well on any phone, in light or dark mode. The admin area works on mobile too.
Two-factor, CAPTCHA and fraud checks
Two-factor sign-in for staff and clients (app or email code), Cloudflare Turnstile or reCAPTCHA on your forms, fraud checks on new orders, and staff roles.
Site health
A nightly check of staff access, file permissions, what strangers can open, settings, Nuvabill's own code, backups and the database, with a score and one-click fixes.
Automations
When this happens, do that: add a late fee after 7 days, welcome new clients, chase quotes, put VIP tickets first. Nine templates, a safe Try it, and a log of every run.
AI help with your own key
Claude drafts ticket replies, translates tickets both ways and writes product texts. Your team checks and sends every reply, and passwords, cards and emails never reach the AI.
Telegram and WhatsApp
Invoices, reminders and ticket replies in the chat apps your clients already use. They link by QR code, and what they write becomes a ticket. Connect WhatsApp by scanning a QR code.
Admin app on your phone
Install the admin area on iPhone or Android from the browser. A Today screen with what needs you, and push alerts for new orders, payments and tickets.
Found on Google
Titles and descriptions for every store page, a sitemap, prices on Google, language links and link previews on WhatsApp and Facebook. Built in, with every theme.
Signed, automatic updates
Every release is signed. Nuvabill checks the signature, makes a backup, then installs the update, and can roll back if something fails.
Marketplace
Install themes, order forms and extensions in one click from your admin area. Every package is reviewed and signed. Behind Cloudflare? Connect to the marketplace with one click. See the marketplace.
Easy to install
Upload, open the web installer and answer a few questions. Runs on shared cPanel hosting with one cron job. MySQL or SQLite.

WHMCS alternative
Looking for a WHMCS alternative?
WHMCS is mature and has a very large module library. Nuvabill is new, but it is free, fully open source and built on a modern stack. If you want readable code, no license fees and a clean mobile interface, Nuvabill is worth a try.
FAQ
Questions and answers
Is Nuvabill really free?
Yes. Nuvabill is open source under the AGPL-3.0 license. You can use it for your hosting business with unlimited clients and no monthly fee. The free edition shows a small "Powered by Nuvabill" link.
What do I need to run Nuvabill?
A server or hosting account with PHP 8.3 or newer, the usual PHP extensions, a MySQL, MariaDB or SQLite database and one cron job. It runs on normal cPanel shared hosting. See the install guide.
Can I move from WHMCS to Nuvabill?
Yes. In Settings, Import first shows a dry run, then copies your clients (they keep their passwords), products and prices, services, domains, invoices, payments and support tickets straight from your WHMCS database. Blesta, FOSSBilling and Paymenter work the same way. The old system is only read, and you can run the import again just before you switch without making copies.
Is Nuvabill ready for production?
Nuvabill 0.7 is an early release, before 1.0. The billing flow, taxes, domains, control panels, payment gateways and marketplace are complete and tested, but test it with your own products, gateways and servers before you move real customers.
Can I remove the "Powered by Nuvabill" link?
Yes. A White-label License removes it from your client area, invoices and emails for $49 a year per site. Enter the key under Settings → License. Test sites are free.
Who makes Nuvabill?
Nuvabill is made by RapidNet Ltd, a hosting company that built the billing system it wanted to use. You can support the work through GitHub Sponsors.
