Openprovider’s WHMCS module: an inside look for web hosters

Manual billing, endless domain transfers, and overloaded support tickets: every web hoster knows the struggle.

WHMCS (Web Host Manager Complete Solution) is the leader platform to automate critical operations like billing and domain management, for web hosting providers.

At Openprovider, we’ve gone a step further with our custom WHMCS module

Designed specifically for domain resellers, it helps you save time, reduce manual work, and focus on serving your customers well.

Curious about how it works? We sat down with Sarath, our WHMCS lead, to discuss how this module works, the problems it solves, and what’s next for this powerful tool. 

What is WHMCS, and how does it help web hosters?

Sarath: WHMCS (standing for Web Host Manager Complete Solution) is a software platform built for web hosting businesses to automate and manage their routine operations. It handles tasks like billing, domain registration, customer support, and client management, covering the entire customer life cycle – from account setup to termination. 

Founded in 2003 to simplify hosting operations, WHMCS began as a one-stop platform for client management, recurring billing, and integrated support for web hosting businesses. Today, 5K+ companies use that as, within the hosting control panels category, Datanyze reports WHMCS at 2.53% market share (5,353 companies)..

For web hosters, WHMCS saves time and reduces manual work. It helps consolidate client accounts, invoices, payments, and support tickets into one platform, which makes your daily operations more efficient. 

This level of automation improves the customer experience and supports business growth without requiring significant additional resources.

How does WHMCS solve key customer problems?

The Openprovider WHMCS module addresses common challenges faced by hosting businesses:

  • Manual domain registration and management: WHMCS automates domain registration, renewals, and transfers directly within one place, helping you save time and resources.
  • Manual billing operations: Our module integrates with WHMCS’s billing system to automate and simplify invoicing for domain-related services, keeping everything accurate and on schedule.
  • Availability checks: WHMCS helps you access up-to-date domain availability information without needing to check external systems, making it faster to manage your domain portfolio.
  • Workload management: Automation reduces the risk of human error and cuts down on operational complexity, freeing up your team to focus on other priorities.
  • Customer experience: A seamless, efficient workflow benefits both your team and your clients, improving satisfaction and reducing the risk of disruptions.

What are the key features of the Openprovider WHMCS module?

Our module integrates seamlessly with WHMCS to automate a wide range of domain-related operations, including:

  • Automated domain registrations, renewals, and transfers
    Execute end-to-end domain actions from WHMCS with Openprovider handling the registry calls. Save time, reduce errors, and keep expiries under control.

    Tag clients to segment portfolios and workflows. Filter, report, and target renewals or promotions by segment.

Our module is fully compatible with PHP 8.1, and our team is constantly working on adding more features and improvements!

What are WHMCS modules and themes?

WHMCS modules are plug-ins that extend the platform’s functionality, connecting your installation to external services like domain registrars, payment gateways, and provisioning systems. Registrar modules, such as Openprovider’s, automate domains end to end inside WHMCS, including registration, transfers, renewals, DNS, and pricing sync. Themes, on the other hand, control the look and feel of the client area and order forms so you can align the experience with your brand without touching core logic. In short, modules power what WHMCS can do, while themes shape how customers see and use it.

What are the most common use cases for the WHMCS module?

The most common use cases for the Openprovider WHMCS module among our customers include: 

  • Domain registration and management.
  • Domain reselling.
  • Domain transfers.
  • DNS and nameserver management.
  • Automated billing.

How to install WHMCS with Openprovider

To install the Openprovider WHMCS domains module into your registrar modules directory, activate it in WHMCS, and add an Openprovider API user with API access as your credentials.

Set Openprovider as the registrar for the TLDs you sell and run the registrar TLD sync to pull current prices.

For a smoother search experience, set Openprovider as the lookup provider and enable name suggestions. If you sell premium domains, switch on premium pricing. Turn on DNS, DNSSEC, and nameserver management as needed. Finally, rely on WHMCS’s native cron-based domain sync to keep statuses and renewals aligned.
