We downloaded and installed this addon with ease. It had such a good impact on us, we purchased their One Page Checkout from and our customers is increasing day by day for easy checkout process. Would highly recommend their addons.

We use their PDF module and have found this very impressive for applying a consistent branding for our business. The HTML Invoices are easy to customize via the Admin Panel. Excellent product to improve the look and feel of WHMS Invoices.
