We need OS Commerce and Paypal IPN integration on our web store. It's currently running OS commerce. We need to have the Paypal integration complete so that orders will switch from sending Paypal IPN to completed once payment on Paypal is complete.
We also need integration of Paypal Payments Pro with proper buttons on the site. Finally we have a custom live orders script from our warehouse that needs to be installed as part of the OS commerce system to transmit orders directly to the warehouse once Paypal payment is completed.
