We need a basic online billing system to allow us to:
See their account and past invoices (PDF viewable)
Have multiple domains under their login
Change accounts, add services, update billing
Email current months billing activities
Integrate with [url removed, login to view] (less important)
Add notes (server, contact, admin notes...)
Schedule tasks (ie, update, SSL..)and see report via staff/date/other
See declined, approved, and pending charges (per period/client)
Add hosting packages and services
Send email to clients based on server, package, or other
Must integrate with PayFLOW Pro payment gateway.
We have the SDK/API if needed.
Must also have a visual GUI than we can skin.
