I'm selling the module for $89.
I've coded the module to do the following:
Setup indefinite subscription payments with Google Checkout
Perform monthly callback to WHMCS informing of payment and marking invoice as paid
ability to have both a setup fee and a recurring fee of different amounts
In future releases (which will be free to those who buy) will include:
Reporting via WHMCS
Refunds via WHMCS
Subscription Cancelations via WHMCS
Free Trial Integration
If you're interested, please shoot me an email at: ablackington@lionlink.net with subject line Google Checkout Module.
Thanks and Regards,
