Hi, currently i am designing a shopping cart in Zend Framework. I decided to write code for user/roles/product catalog from scratch which i have already done and tested. But for other things i need you guys to guide me which are the best classes/libraries to build this system system.
I need following functionality as
- Order
- Inventory
- Accounts
- Paypal Integration
- UPS/USPS/Fedex Integration.
and thanks for your time.
Note: I have already gone through magento modules, its bit difficult to extract from it what i need, so it will be last resort for me.
