I would like to propose you to develop the iOS and ANDROID apps using PhoneGap. It will be cost efficient for you. Are you fine with that?
All the core eCommerce features like customer account signup, advanced search, various categories, place orders, checkout, inventory management system, online payment gateway- PayPal/Credit card, track orders, social media (Facebook, Google +, etc.) widgets and APIs, etc. will be developed and integrated within the apps.
We will build a user friendly ADMIN PANEL (using PHP or ASP) so you can manage/update the apps easily.
Finally after completion we'll deliver the full Source Code, assist you to launch the apps on Google play and iTunes store and provide you 6 months of Free Support.
So kindly revert back to me with the design and project scope.
We are available to start the job right away. Looking forward to hear from you soon.
Thank you
Warm regards,
