Sorry for the inconvenience.
Mainly, our template is an HTML template and we have just provided WHMCS template for FREE of cost with our HTML template by customizing WHMCS default six template’s header, footer and color based on our HTML template.
In this case, you need to use both HTML and WHMCS templates separately. HTML template to show/represent your products/services and WHMCS template for billing like as our demo.
Moreover, you need to link up all of your products/services (buy now link) to your WHMCS.
