WordPress provides springboard for single-page checkout system.
Bonnie Harriman and I designed Trademark Your Company for New York-based IP lawyer John M. Trani, who wanted to sell his legal services with a series of single-page forms while promoting his practice through blogging.
John needed to be able to allow visitors to buy his services directly from his website in a variety of flexible packages. Using WordPress and the PayPal Payments API, I created a form-building system that allowed John to deploy different service packages all from within the Dashboard. Each single-page checkout allowed John to combine a variety of services so that visitors could buy the package directly from the website.
