Questions About Our WHMCS Add-ons

Where can I read your Terms of Service?

Our Terms of Service cover licensing, support and acceptable use. Read them here: Terms of Service. For data handling, see our Privacy Policy.

Do you offer a money-back guarantee?

Yes — a 30-day money-back guarantee on new license purchases if the add-on doesn’t meet your needs. Custom development and installation services are excluded. Request a refund via support ticket within 30 days.

What does support include?

Standard support covers bug fixes, configuration questions, and compatibility updates for supported WHMCS/PHP versions. Typical responses within 1 business day. Installation and custom changes are available as paid services.

What are the system requirements?
  • PHP: 8.x or higher (with an ionCube Loader compatible with your PHP version)
  • WHMCS: 8.13.x or higher
  • License: A valid WHMCS license is required to run these add-ons in production

Running older versions? Contact us for upgrade guidance.

How many sites can I run this on?

Licenses are per WHMCS installation and include one production plus one staging/dev instance. Need multiple installs or an agency plan? Contact us for bundle pricing.

How do renewals and updates work?

Your license includes 12 months of updates and support. After that, renew to keep receiving new versions and compatibility updates. The module continues to work if you don’t renew—you just won’t get new releases or support.

Do you provide installation or custom development?

Yes. We offer paid installation/config and custom module development (new hooks, UI, integrations). Share your requirements via contact or open a ticket.

Is the code ionCube encoded? Do you provide source code?

Our commercial WHMCS add-ons are distributed ionCube-encoded. A compatible ionCube Loader must be installed on your server.

We do not provide unencrypted source code as part of any license. Where applicable, configuration, templates, and language strings remain editable; the core PHP logic is encoded.
