Our reseller hosting plans are built on cPanel and WHM, so they work with any billing and client management platform that integrates with cPanel. We do not lock you into one product or bundle our own. This guide covers what billing software does for a reseller, every major platform that integrates with a cPanel and WHM reseller account (commercial and free open source), an at-a-glance comparison, and how domain registration and transfers fit in.

Any cPanel-Compatible Billing Platform Works
You are free to run whatever billing software you prefer on your reseller account, as long as it integrates with cPanel and WHM. That covers the paid industry standards and the free open source options alike.
- Paid and well supported: WHMCS, Blesta, HostBill, ClientExec, WISECP, Ubersmith
- Free and open source: FOSSBilling (the maintained successor to BoxBilling)
- All of them automate cPanel account creation, suspension, and renewals over the WHM API
- Domain registration and transfers run through a registrar module, not through us
We Provide the Hosting, Not the Billing Software
Ultra Web Hosting gives you the reseller account and the WHM access these tools plug into. The billing platforms below are third-party products. We do not sell, license, or provide technical support for the software itself. The open source ones are free to download and use; the commercial ones you license directly from their vendor.
- You install and run the panel on your own hosting
- Vendor or community handles support for the software
- We support the cPanel and WHM side it connects to
01. What Billing Software Does for a Reseller
When you resell hosting, you are running a small hosting company. Billing and client management software is the back office that makes that practical without doing everything by hand. A good platform ties three jobs together:
- Billing. It creates invoices, charges cards on a schedule, sends payment reminders, and applies late suspensions automatically. Your customers get a client area where they can view invoices and pay.
- Provisioning. When an order is paid, it talks to WHM and creates the cPanel account for that customer automatically, with the right package and limits. If a customer cancels or does not pay, it suspends or terminates the account.
- Support. Most platforms include a support ticket system, a knowledgebase, and announcements so you have one place to run customer service.
Without it, you would be manually creating cPanel accounts in WHM, tracking who owes what in a spreadsheet, and chasing renewals by email. The software turns that into a mostly hands-off pipeline.
To actually collect money, each platform connects to a payment gateway such as PayPal or Stripe through a built-in module. You add your gateway account once, and the panel then charges cards and records payments against invoices automatically. All of the platforms below support the common gateways.
02. What Compatible Actually Means
People often ask whether we offer WHMCS or a similar tool. The honest answer is that we do not provide or bundle any billing platform, and you do not need us to. What matters is that our reseller accounts run on cPanel and WHM, and every serious billing platform ships a cPanel and WHM integration module.
So compatible here means the software knows how to log into your WHM over its API and manage accounts on your behalf. You choose the platform, install it, and point it at your reseller account. We are not the gatekeeper for that choice.
Before you commit to a platform, check its module directory or documentation for a current cPanel and WHM provisioning module. Every option in this guide has one. If you ever evaluate a niche platform not listed here, that is the one feature to confirm first.
03. Commercial Platforms
These are paid, vendor-supported products. You license them directly from the vendor, and in return you get mature integrations, larger add-on ecosystems, and someone to call when something breaks.
WHMCS
WHMCS is the most widely used billing and automation platform in the hosting industry, and it is what most resellers mean when they ask about billing software. It is closed source and licensed on a subscription basis.
- Deepest cPanel and WHM integration. Account creation, suspension, termination, package changes, and single sign-on to cPanel are all built in and heavily tested.
- Largest module ecosystem. Payment gateways, domain registrars, and hundreds of add-ons exist because nearly every vendor targets WHMCS first.
- Mature and heavily documented. Almost any question you hit has been answered already.
The trade-off is an ongoing license fee and that you cannot modify the core. For a reseller who wants the most proven, best-supported option, WHMCS is the safe default.
Blesta
Blesta is the most common alternative to WHMCS. It is also paid and licensed, usually at a lower cost, with a reputation for a clean, readable codebase and a strong stance on security.
- Native cPanel and WHM provisioning module
- Domain registrar and payment gateway modules for the common providers
- Developer-friendly if you plan to customize or extend it
Its add-on ecosystem is smaller than WHMCS, so a very specific third-party module may not exist. For most standard reseller setups that is not a problem, and many resellers prefer Blesta for the price and code quality.
HostBill
HostBill is a commercial platform with a very large feature set aimed at bigger operations, with a lot of built-in modules and automation options.
- cPanel and WHM provisioning plus a wide catalog of first-party modules
- Strong at complex product configurations and upgrade paths
- Licensing and complexity are more than a small reseller usually needs
Consider HostBill if you are scaling into a larger provider and want a lot of automation out of the box. For a starting reseller it can be overkill.
ClientExec
ClientExec is a long-running commercial billing platform pitched as a simpler, budget-friendly option. It covers billing, support, and cPanel and WHM provisioning without the depth (or the price) of WHMCS.
- cPanel and WHM provisioning module
- Lower cost, gentler learning curve
- Smaller ecosystem than WHMCS or Blesta
WISECP
WISECP is a newer commercial platform with a modern interface, built-in client area, and support desk. It ships cPanel and WHM integration and targets resellers who want a contemporary look without assembling many add-ons.
- cPanel and WHM provisioning module
- Modern UI and integrated support desk
- Growing but smaller module ecosystem
Ubersmith
Ubersmith is enterprise-grade billing, infrastructure, and device management software. It is aimed at large hosts, data centers, and infrastructure providers rather than individual resellers.
- Enterprise billing and automation with cPanel and WHM support
- Heavier and more expensive than a small reseller needs
- Listed for completeness; usually the wrong fit for a starting reseller
You may also come across AWBS, an older commercial billing system that supported cPanel and WHM. It still exists but sees far less activity and mindshare than the platforms above. If you are choosing today, start with an actively developed option.
04. Free and Open Source Platforms
If you want to start without a software license fee, the open source route is the one to look at. You give up vendor support and some polish, but you pay nothing for the software and you can read and modify the code.
FOSSBilling
FOSSBilling is free, open source, and actively maintained, and it is the modern continuation of the older BoxBilling project. It covers the core reseller workflow: client area, invoicing, support tickets, and automated provisioning.
- Free to download and use. No license cost, which lowers the barrier when you are getting started.
- cPanel and WHM server manager module. It creates and manages accounts on your reseller account over the WHM API like the paid tools do.
- Open source. You can read, audit, and modify the code, and the community drives development.
BoxBilling
BoxBilling is the older open source billing system that FOSSBilling forked from. The original project has seen little recent activity, so if you are choosing between the two open source options today, pick FOSSBilling. It is the one under active development, and running an unmaintained billing panel that holds customer and payment data is a risk not worth taking.
Open source billing software is free to run, but you are responsible for keeping it patched and secure. A billing panel holds customer data and payment details, so run current versions, apply updates promptly, and put it behind SSL. The feature set is also still maturing compared to WHMCS, so confirm the specific gateway and registrar modules you need exist before you go live.
05. At-a-Glance Comparison
Every platform below provisions cPanel and WHM accounts and connects to domain registrars through a module. The differences are cost, maturity, and who they are built for.
| Platform | License | Best For |
|---|---|---|
| WHMCS | Paid (subscription) | The proven default; largest ecosystem and docs |
| Blesta | Paid (lower cost) | Clean code, security focus, customizers |
| HostBill | Paid | Larger operations wanting heavy automation |
| ClientExec | Paid (budget) | Simpler, lower-cost commercial option |
| WISECP | Paid | Modern UI with an integrated support desk |
| Ubersmith | Paid (enterprise) | Data centers and large infrastructure providers |
| FOSSBilling | Free, open source | Starting out with no license cost |
| BoxBilling | Free, open source (legacy) | Superseded by FOSSBilling; not recommended new |
Do not over-optimize the choice. All of these run the same core reseller workflow on our accounts. If you are unsure, start with FOSSBilling to test the waters for free, or WHMCS if you want the most support and the widest module selection from day one.
06. Registering and Transferring Domains Through Your Panel
Yes, these platforms can register and transfer domains for your customers, and they can do it automatically as part of an order. The important detail is how that works, because it is a common source of confusion.
The billing panel does not register domains by itself. It connects to a domain registrar through a registrar module, and the registrar is who actually registers, renews, and transfers the domain. To offer domains you need a reseller or API account with a registrar such as eNom, ResellerClub, or a similar provider, then you enter that account's API credentials into your billing panel.
- Open a reseller or API account with a domain registrar of your choice.
- In your billing panel, enable that registrar's module and enter the API credentials.
- Set your selling prices per TLD in the panel.
- From then on, when a customer orders or transfers a domain, the panel calls the registrar API and handles registration, transfer, and renewal automatically alongside the hosting.
Your Ultra Web Hosting reseller account is for hosting. Domain registration comes from the registrar you connect to your billing panel, not from us. For how transfers work at the domain level, see article 30.
07. How the Panel Connects to Your Reseller Account
All of these platforms talk to your reseller account the same way: through the WHM API. Once configured, the panel logs into WHM as your reseller user and manages customer cPanel accounts for you.
- In WHM, generate an API token for your reseller account (this is safer than storing your password in the panel).
- In your billing platform, add a server and enter your WHM hostname, your reseller username, and the API token.
- Create hosting packages in the panel that map to the cPanel packages available under your reseller plan.
- Test provisioning with a trial order. A paid order should create the cPanel account automatically; a cancellation should suspend or terminate it.
The packages you define in the billing panel must fit within the disk, bandwidth, and account limits of your reseller plan. If you oversell beyond what your plan allows, provisioning will fail or accounts will hit limits. Keep the panel packages and your reseller plan in sync.
08. Where to Install Your Billing Panel
Your billing platform is a web application, so it needs to live on a hosting account somewhere. For a reseller, the natural home is a dedicated domain or subdomain on your own account, for example billing.yourbrand.com or a client area at my.yourbrand.com.
Some of these platforms can be installed in a few clicks from Softaculous in cPanel, which handles the database and files for you. Others you download from the vendor and upload manually. Either way the placement and security advice below is the same:
- Give it its own cPanel account or domain. Keep the billing panel separate from customer sites so it is easy to secure and back up.
- Put it behind SSL. A billing panel handles logins and payment data, so it must run over HTTPS. Every Ultra plan includes free AutoSSL; see article 68.
- Check the requirements. Confirm the PHP version and extensions the platform needs. You can set the PHP version per domain in cPanel; see article 425.
- Back it up. This is the system that runs your business. Keep regular backups; see article 467.
09. Choosing the Right One
There is no single right answer. It comes down to budget, how much you want to customize, and how much hand-holding you want from documentation and vendors.
FOSSBilling
Best when you want to launch without a software license cost and are comfortable maintaining open source software yourself.
- No license fee
- Open source and actively maintained
- Covers the core reseller workflow
- You handle updates and security
WHMCS or Blesta
Best when you want the most proven integration, the largest module ecosystem, and vendor support, and you do not mind an ongoing license fee.
- Mature, heavily documented
- Widest choice of gateways and add-ons
- Vendor support for the software
- Ongoing license cost
A practical path many resellers take is to start on FOSSBilling to keep early costs down, then move to WHMCS or Blesta once the customer base grows enough to justify the license. Whichever you choose, our reseller account works with all of them.

Ask Our Team a QuestionQuick Recap: Reseller Billing Software
If you only take a few things from this guide, take these:
- Any cPanel-compatible platform works with our reseller accounts. We do not lock you into one or bundle our own.
- Commercial: WHMCS (the standard), Blesta, HostBill, ClientExec, WISECP, and Ubersmith for enterprise.
- Free and open source: FOSSBilling, which is the maintained successor to the legacy BoxBilling.
- Domains run through a registrar module, meaning you connect a registrar account to your panel; domain registration does not come from us.
- The panel connects to WHM over an API token to create and manage cPanel accounts, and it should live on its own domain behind SSL.
