An embodiment includes a system comprising an initialization module and a platform module. The initialization module provides an initialization interface to a merchant that receives an indication from the merchant to initialize creation of a storefront application. The platform module receives a selection of mobile phone device operating systems; accesses stored templates from a template database, and maps elements in the stored templates to portions of source code to generate sets of operating system-specific source code. The stored templates correspond to the selected mobile phone device operating systems. The stored templates include source code used to implement portions of the storefront application on a mobile phone device operating system. When compiled, the sets of operating system-specific source code become versions of the storefront application executable by a respective one of mobile phone device operating systems.
