Prestashop’s one page checkout optimization

For our client we have optimized Prestashop’s one page checkout form in respect of:

  • improved arrangement of the form fields,
  • additional fields validation,
  • fields visibility changes,
  • adding ‘I want to receive a VAT invoice’ checkbox,
  • locating billing address next to the delivery address,
  • responsive css styling.
  • other.

Above changes required modification of the OrderOpcController (OrderOpcController.php), javascript code in order-opc.js, template order opc.tpl and other more than 14 files.

Optimizing the one page checkout form aims at improving the ergonomics, intuitive operation and communication in the process of order completion. Accurate optimization should increase the ratio of orders placed to the filled baskets (reduce the number of abandoned shopping carts). Case studies also show, that 80% of the basic optimization changes of the one page checkout may lead to an increase in average order value by 20%.
