Installing Billing Software: Blesta, WHMCS, and HostBill Compared

If you run a hosting company, MSP, web agency, or domain reseller, billing software becomes the system of record for the business. It raises invoices, tracks renewals, provisions services, sends overdue notices, stores client details, and often holds API credentials for control panels, registrars, and payment gateways.

This guide compares Blesta, WHMCS, and HostBill, then gives a practical installation path for each. The WHMCS and HostBill sections have been checked against their current official documentation and pricing pages in April 2026.

Quick Recommendation

Choose Blesta if you want monthly or owned licensing, unlimited clients on the listed licence plans, and a self-hosted platform with a lower entry cost than many enterprise-focused alternatives. For licences, Blesta.club is our preferred reseller.

Choose WHMCS if you specifically need its mature integration ecosystem, third-party module availability, and hosting-industry familiarity.

Choose HostBill if you want a one-time licence, need infrastructure-heavy automation, and are comfortable paying more upfront for the edition that includes your required integrations.

Platform Comparison

Current Pricing Snapshot

Pricing changes often, so always check the vendor before buying. As of April 2026:

• WHMCS self-hosted starts at $34.95/month for up to 250 active clients, then $54.95/month for up to 500. Business tiers start at $84.95/month for up to 1,000 active clients.
• HostBill starts at $599 one-time for Startup, then $999 for Enterprise, $1,599 for Data Center, and $5,999 for All-Inclusive. Listed packages are lifetime-valid licences with one year of update access.
• Blesta currently offers monthly and owned licence options, including plans with unlimited clients and staff. Check current Blesta pricing before ordering. We recommend checking Blesta.club as our preferred reseller for licences and Blesta-focused add-ons.

Do not host billing software in the same account as ordinary customer websites. Your billing system contains customer data, invoices, service credentials, and provisioning API keys. At minimum, use a separate shared hosting account. For production, use a VPS or dedicated server.

Where Should It Run?

The right hosting environment depends on risk and scale:

• Testing and early setup: a separate TekLan shared hosting account is fine if the software requirements are met.
• Live provider: use a VPS so you control PHP, ionCube, cron, firewall rules, backups, and logging.
• High-volume or audited environment: use a dedicated server or isolated infrastructure with a documented backup and recovery plan.

Installing Blesta

Blesta remains a practical starting point for many smaller providers. Use a dedicated hostname such as billing.yourdomain.co.uk, create a database, upload the Blesta files, run the web installer, then configure cron from Settings → System → Automation.

For a detailed walkthrough, use our dedicated guide: How to Install Blesta on Your Hosting or VPS.

Blesta Checklist

• Dedicated billing hostname.
• Correct PHP version and extensions for your Blesta release.
• Dedicated database and database user.
• Cron configured exactly as shown in Blesta, using the schedule recommended for your version and workload.
• HTTPS forced before entering real customer or payment data.
• Test invoice and payment completed before launch.

Installing WHMCS

WHMCS is a good fit when its integrations outweigh the ongoing subscription cost. The current WHMCS 9.0 requirements are stricter than older guides: PHP 8.2 or 8.3, current ionCube Loader, and a traditional Linux/Apache/MySQL/PHP environment.

WHMCS Requirements to Check First

• Linux operating system.
• Apache 2.x, with mod_rewrite recommended.
• PHP 8.2 or PHP 8.3.
• ionCube Loader 13.0.2+ for PHP 8.2, or 14.4.0+ for PHP 8.3.
• MySQL, with MySQL 8.x recommended.
• MySQL strict mode disabled.
• System cron running every five minutes.

WHMCS Install Outline

1. Create billing.yourdomain.co.uk or another dedicated hostname.
2. Enable PHP 8.2/8.3 and the required ionCube Loader.
3. Create a dedicated database and user.
4. Upload WHMCS and run /install/install.php.
5. Delete the install/ directory.
6. Set configuration.php to 400.
7. Copy the exact cron command from Automation Settings and run it every five minutes.
8. Rename the admin directory and enable two-factor authentication.

Installing HostBill

HostBill is the most infrastructure-focused of the three. Its official manual installation requirements include Linux, PHP 8.1 minimum, MySQL 5.7+ with strict mode disabled, ionCube Loader 10.1+, and the required PHP extensions. HostBill's April 2026 compatibility update says current updates require PHP 8.1, 8.2, or 8.3.

HostBill Requirements to Check First

• Linux-based operating system.
• PHP 8.1, 8.2, or 8.3 for current updates.
• ionCube Loader 10.1 or later.
• MySQL 5.7+ with strict mode disabled.
• cURL with SSL, MBstring, BCMath, JSON, PDO, PDO_MySQL, and FileInfo.
• Main cron every five minutes.
• Queue job every minute.

HostBill Install Outline

1. Create a dedicated billing hostname.
2. Enable a supported PHP version and ionCube.
3. Create a dedicated database and user.
4. Upload HostBill files to the public directory.
5. Rename includes/config.php.example to includes/config.php.
6. Make templates_c/ and includes/config.php writable for the installer.
7. Run /install/index.php and activate the licence.
8. Delete or rename install/.
9. Set includes/config.php to 444.
10. Configure admin/cron.php every five minutes and queue.php every minute.

Final Go-Live Checklist

• Billing platform isolated from customer websites.
• HTTPS forced everywhere.
• Installer removed.
• Config file permissions locked down.
• Cron jobs verified in the application's automation logs.
• Admin users protected with strong passwords and two-factor authentication.
• Payment gateway tested with a real test invoice.
• Domain registrar, server module, and email delivery tested before public launch.
• Database and file backups configured, monitored, and test-restored.

Hosting the Billing Area Safely

Your billing platform should not live inside the same public directory as a customer website. Use a dedicated hostname such as billing.example.co.uk, a separate database, separate credentials, and a clear backup plan. If you want managed PHP, SSL, cron, and database tooling, start with application hosting. If you need full control over the operating system, queue workers, custom modules, and firewall policy, use a VPS.

For resellers, the billing system is only one part of the setup. You also need product groups, order forms, domain pricing, server modules, support departments, email templates, and a cancellation process. TekLan reseller hosting works well with Blesta, WHMCS, HostBill, Upmind, Clientexec, and Paymenter.

Which Billing Platform Should a Small Host Choose?

• Choose Blesta if you want a clean billing core, straightforward licensing, and a lighter operational footprint. For licences, we prefer Blesta.club.
• Choose WHMCS if you need the largest third-party module ecosystem and you are comfortable with its licensing model.
• Choose HostBill if infrastructure automation and a broader built-in feature set matter more than a lower entry cost.

Before launch, also read the reseller hosting setup checklist, client area security checklist, and email deliverability basics.
